GDS3705 APPLICATION SCENARIOS

The GDS3705 Door System can be used in different scenarios.

Peering Mode without SIP Server

For environments like remote warehouse/storage, grocery store, small (take-out) restaurants, just using static IP with PoE switch to form a LAN, using Grandstream’s audio phone GXP21XX/17XX/16XX series, the GDS3705 will meet your very basic intercom and open-door requirements.

This is the solution to upgrade the traditional analog Intercom system. All you need is a Power source, Switch or PoE Switch, and Grandstream IP phones.

The equipment list can be found below:

  • GDS3705
  • Grandstream IP Phones
  • PoE Switch with related Cat5e/Cat6 wiring

Peering using SIP Server (UCM6XXX)

For large deployment, multiple GDS3705 units might be required, peered connection will not work in such case due to multiple connections. Such scenarios require an IPPBX or a SIP Proxy to accomplish the tasks.

If remote access is required, a router with internet access should be added to the below-needed equipment list:

  • Several GDS3705
  • UCM6XXX or another SIP Server
  • Grandstream IP Phones
  • PoE Switch with related Cat5e/Cat6 wiring
  • Electronic Lock
Figure 13: Peering GDS3705 with UCM6XXX

GDS3705 PERIPHERAL CONNECTIONS

Below is the illustration of GDS3705 peripheral connections for related applications.

Figure 14: Peripheral Connections for GDS3705

Alarm IN/OUT

Alarm_In could use any 3rd party Sensors (like IR Motion Sensor).

Alarm_Out device could use 3rd party Siren, Strobe Light, or Electric Door Striker, etc.

The figure below shows an illustration of the Circuit for Alarm_In and Alarm_Out.

Figure 15: Alarm_In/Out Circuit for GDS3705

Notes:

  • The Alarm_In and Alarm_Out circuit for the GDS3705 should meet the following requirement:

Alarm Input

3V<Vin<15V, PINs (1.02KΩ)

Alarm Output

125VAC/0.5A, 30VDC/2A, Normal Open, PINs

  • The Alarm_In circuit, if there is any voltage change between 3V and 15V, as specified in the table above, the GDS3705 Alarm_In port will detect it and trigger the action and event.
  • Higher voltage and wrong polarity connection are prohibited because this will damage the devices.

Protection Diode

When connecting the GDS3705 to a door strike it is recommended to set an EMF protection diode in reverse polarity for secure use, below are examples of deployment for the protection diode.

Figure 16: Protection Diode – Example 1

The reverse EMF protection diode must always be installed in reverse polarity across the door strike.

Figure 17: Protection Diode – Example 2

Connection Examples

Below are examples, show how to use wiring on the back cover of the GDS3705 to connect with external devices. The “NO” (Normal Open) model strike is used as an example, “NC” (Normal Closed) should be similar and users need to decide which model (NO or NC) to be used on the door.

Wiegand Module Wiring Examples

GDS3705 package is shipped with one Wiegand cable for Input/Output Wiegand connections. The following examples show how to connect the Wiegand Input/Output devices to the GDS3705.

Input example with 3rd party power supply for Wiegand device

Figure 23: Wiegand Input Example with 3rd party Power Supply

Make sure to connect the GND of the Wiegand device and the GDS3705 Wiegand port.

For Wiegand input mode, LED and Beep pins require that the Wiegand device support those interfaces. These two pins will not affect the Wiegand bus when not connected.

Input example with power supply for both GDS3705 and Wiegand device

Figure 24: Wiegand Input Example with Power Supply for GDS3705 and Wiegand Device

If the power source is 12VDC, the Wiegand device can share the same power source as GDS3705. However, users need to check the max power consumption and the max capability of the power source.

If Wiegand device is using 5VDC, GDS3705 Wiegand port can provide 5VDC with max 500mA to power up Wiegand device.

Output example with 3rd party power supply for Wiegand device

Figure 25: Wiegand Output Wiring Example

When the Wiegand output of the GDS3705 is connected, it acts as the signal receiver of the 3rd party Wiegand device, connecting to the door controller. The major wiring is GND, D0, and D1. Because usually, the door controller will consume a big current and power, the power supply should be separated.

Wiegand RFID Card Reader Example

Figure 26: Wiegand RFID Card Reader Example

Siren alarming when the door opened abnormally

When this feature is enabled (special wiring required, see below wiring diagram), an abnormal open door will be detected by the DI port (Alarm_In2 or IN2 in the below diagram showed) if wired correctly (connecting the COMx port to DIx port) therefore trigger the siren alarm. Once an abnormal open door alarm is triggered, the siren will sound non-stop, until manually overridden by a related person.

There are several ways to stop and disable the alarm:

  1. Power cycle the GDS3705
  2. Pick up the Alarm Phone Call (if configured)
  3. Open Door using a PIN (either public PIN or private PIN)

Once the alarm is triggered, the GDS3705 will play a siren sound, send an email to the administrator (if configured SMTP); call the configured alarm SIP phone, and send the alarm output (if connected). Users will only be able to disable the siren using the 3 methods mentioned above.

For detailed action information please refer to GDS37xx User Manual, “Alarm Action Settings” configuration. Below are some diagrams showing the correct wiring to enable this new security enhancement feature.

Open Door via GDS3705 with or without a SIP Call

This feature needs related matching GDS3705 firmware to work. The minimum firmware version needed:

  • GDS3705: 1.0.1.16 or higher.

From the GDS3705 side, the configuration is the same. The only difference is the number of doors to be controlled: If using Local Relay controlled by GDS3705, TWO DOORS can be controlled.

If using GSC3570 Relay, ONLY ONE DOOR can be controlled. The PIN and other settings are the same as SIP remote open door or GSC3570 secure open door.

The difference will come out in the touch screen UI operation of GSC3570.

Figure 31: GDS3705 Configuration Example

Figure 32: GSC3570 Configuration Example

Door opening with SIP Call

When GSC3570 established a call with GDS3705, the screen will display the virtual open door button(s), and the user will press the button to open the door:

Figure 33: Open Door with SIP Call

Door opening without SIP Call

At the GSC3570 idle screen, press “Monitor →Door system”, and the related GDS305 will be displayed. In the blue bar, left is a “Phone” icon and right is the “Open door” icon. The“Phone” icon will establish the SIP call as the previous firmware behaved.

Press the “Open door” icon, and the GSC3570 will open the door directly and NO SIP CALL will be established. Depending on how many doors are controlled, if one door is configured, the door will open directly; if two doors are configured, another screen will pop up to allow the user to choose which door to open, as shown below:

Figure 34: Open Door without SIP Call

When the door is successfully opened the following message will appear:

Figure 35: Open Door without SIP Call

Secure Open Door via GDS3705/GSC3570 Peering

This secure open door feature needs to include GSC3570 to make it a whole solution. The GDS3705/GSC3570 will be peering together in LAN/WAN via IP/SIP, and the door lock/strike will be wired to the GSC3570Alarm_Out port and controlled by GSC3570. This way the strike control is inside the building with enhanced security. Below is a setup example:

Figure 36: GSC3570 secure open door via GDS3705

Note: Minimum firmware required for this to work:

  • Outdoor Device: GDS3705 firmware 1.0.1.116 and higher.
  • Indoor Device: GSC3570 firmware 1.0.5.9 and higher.

For “Secure Open Door”, the GSC3570 is paired with GDS3705. The GSC3570 controls the relay/strike/lock from inside the building (Unlike GDS3705 installed outside), but only ONE door can be controlled because GSC3570 only has one Relay Control circuit built-in. This pairing can be via LAN/WAN but LAN is recommended and actually, most of the application scenes are in a LAN environment because most likely the GSC3570 and GDS37xx are in the same building.

For the GSC3570 and GDS37xx pairing, it can be used via SIP only (Cloud or UCM); IP only (No SIP proxy or UCM but static IP address), and Mixed (SIP and fallback to IP if Proxy failed).

GDS3705 Web Configuration

This setup can be found under the device web UI under, Door System SettingsBasic Settings:

Figure 37: GDS3505 Web GUI configuration for a secure open door with GSC3570

GSC3570 Web Configuration

The GSC3570 side also need to be configured accordingly, like below example:

Figure 38: GSC3570 Web GUI configuration for secure open with GDS3705
Notes

  • If the solution/integration is using a static IP address without SIP Proxy, all the devices involved (GDS/GSC/IP Phone) should choose “NAT Traversal” to “No” and should NOT “Use Random Port”, otherwise will have a problem of ghost call (SIP signaling working but NO media).
  • The IP phone or GSC3570 can use any empty SIP account, meaning it can be mixed if Account 1 is registered to UCM/Proxy and Account2 (blank) to use IP (but the account has to be configured as “Active”).

GDS3705 HOME WEB PAGE

  • Once the IP address of the GDS3705 is entered on the user browser, the login web page will pop up allowing the user to configure the GDS3705 parameters.
  • When clicking on the “Language” drop-down, supported languages will be displayed as shown in the Figure below. Click to select the related webpage display language.
Figure 39: Change Language Page
Note

Current firmware supports only English (default) and simplified Chinese.

GDS3705 SETTINGS

Door System Settings

Users can configure system operations parameters, like input PIN for the door, and manage users’ settings.

Basic Settings

Figure 40: Door System Settings Page

Door Relay Options

There are two choices in the pull-down selection: Local Relay and Webrelay.

  •  Local Relay: Local Relay is the GDS3705 controlling the relay. The strike is wired into the COM2 or COM1 port of the GDS3705 depending 1 door or 2 door need to be controlled.

  • Webrelay: When Webrelay is selected, customers need to continue configure the webrelay IP address or domain name, together with credentials like Username and Password. When legal open door event happened, the configured web relay will get the communication from GDS3705, and will operate the strike to open door for the authenticated open door request.

Note: In web relay mode, the strike is wired to the web relay controller device.

Webrelay URL ON

When Door relay Option set to Webrelay, then enter the correct URL used by the third party controller so that the GDS3705 send the command to activate the relay.

This adds an extra layer of security so when legal open door event happened, the configured web relay will get the communication from GDS3705, and will operate the strike to open door for the authenticated open door request or use that command to operate other industry application. 

Notes:

  • Now there are two Webrelay URL fields available, with On or Off URL command allowed or other usage URL command allowed. Also allow Username and Password configured if the 3rdparty Webrelay requiring this security feature.

  • If some 3rd party Webrelay only support one URL command, then just leave another Off URL blank, or put whatever there as long as it is NOT a URL command.

Webrelay URL OFF

When Door relay Option set to Webrelay, then enter the correct URL used by the 3rd party controller so that the GDS3705 send the  command to disable the relay.

Webrelay Username

Enter the web relay username.

Webrelay Password

Enter the web relay password.

ALMOUT1 Feature

This option allows to choose to use Alarm_Out (COM1) interface for either as alarm out with 3rd party device, or to control a second door “Door 2” (the two functions are mutual exclusive).

When option “Open Door” is selected, will enable GDS3705 to control the operation of two doors via RFID, local and remote PINs.

ALMOUT1 Status

Select Normal Open or Normal Close depending on the lock used.

Delay before Unlock (s)

Device will open door after specified delay (in seconds) when user issuing the authorization.

Unlock Holding Time (s)

Configures the lock holding time, in seconds (default value is 5 seconds).

Device will hold the door unlocked for this specified duration.

Range: 1-1800 seconds.

Minimum Interval of Swiping Card (ms)

Defines the interval in ms to swipe consecutive RFID cards. The range should be between 0ms and 2000ms. Default 300 ms.

Call Mode

Chooses whether to make call to the SIP number or Virtual Number when dialing from the GDS3705 keypad.

Doorbell Mode

Configures the action to be taken when the doorbell is pressed, three options are available:

  • Call Doorbell Number: when Doorbell is pressed, a call will be made to the “Number Called When Door Bell Pressed”. *This option will be the only available when ALMOUT1 Feature is set to Open Door.

  • Control Doorbell Output (Digital Output 1): when Door Bell is pressed electronic lock for Output 1 is opened.

  • Both of Above: When selected, both Call Doorbell Number and Control Doorbell Output options are enabled.

Doorbell Call Out Account

This option sets the account to be used to make call upon the doorbell trigger. If set to Auto, the GDS will use the first available account.

Door Bell Call Mode

Select the ring strategy for the Numbers Called when pressing the Door Bell button to be either Serial or Parallel:

  • Serial Hunting: the configured extensions and/or IP addresses will ring one after one by order.

  • Parallel Hunting: The configured extensions and/or IP addresses will ring simultaneously (up to 4 simultaneous SIP calls).

Number Called When Door Bell Pressed

Configures SIP extension number (SIP Server mode), or IP address with port number (peering mode), to be called when the Door Bell is pressed:

  • SIP Server Mode:

  • The field can be configured to store multiple one or multiple SIP extensions, if configured with multiple extensions (ex: 1001, 1002, 1003), separated with “,” the GDS3705 will ring one extension after the other in a Serial Hunting Mode (GDS will ring each extension by default 15 seconds, this can be changed on the Ring Timeout) or ring them simultaneously in Parallel Hunting Mode.

  • When using UCM, users can also configure there a Ring Group extension (6400 for example) that will ring multiple extensions simultaneously, or one by one depending on the Ring Group ring strategy

  • If all phones are GXP21XX, users can open door either by pressing Remote_PIN# or by pressing Open Door button if already configured.

  • If early medial is enabled on phone side, user can send the PIN code using the Open-Door button before answering the call (Of course users can open the door also after answering the call).

  • Peering Mode:

  • User should configure multiple IP addresses of phones instead of SIP extensions, when Door Bell pressed the GDS3705 will ring the configured IP Addresses in Serial or Parallel Mode according to Doorbell Call Mode strategy.

Note: This field supports a Maximum of 256 characters.

Remote PIN to Open the Door

Configures PIN code stored in the GDS3705, remote SIP phone needs to input and match this PIN (the PIN is sent via DTMF while in call) so that the GDS3705 can open the door.

Note: For enhanced security, when the call is initiated from GDS then only the numbers existing in “White List” will be able to use DTMF PIN to open door remotely.

Maximum Number of Dialed Digits

Configure the maximum digits allowed to dial in the keypad. Once the configured condition satisfied, the device will send out the digit to call automatically without pressing #. Disabled if set to 0.

Three options are available: Private Card PIN, Unified PIN or Card and Private PIN.

  • Private PIN: Means every member has a private PIN, the GDS will record who unlocked the door every time. Users need to enter the following sequence from the GDS3705 to open the door [*Virtual Number*Private PIN#].

Notes:

  • When Local PIN type is set to private PIN, users can also open the door by swiping their cards.

  • If “Disable Keypad SIP Number Dialing” is checked, users will be able to open door using private PIN with following sequence [Private PIN#].

Note: Door can still be opened by Card and with the sequence [*Virtual Number*Private PIN#].

  • Unified PIN: Means all members share a same PIN to unlock the door. Users need to enter the following sequence from the GDS3705 keypad to open the door [*Local PIN to Open Door#].

  • Card & Private PIN: Means every member needs to swipe his card and enter his private PIN to open the door using the following sequence [Swipe the card + * Private PIN#]

Local PIN to Open Door

Configures PIN stored in GDS3705, input locally this PIN on the GDS3705 keypad will unlock the door.

This feature needs Private PIN, means every member has a private PIN, the GDS will record who unlocked the door every time.

Users need to enter the following sequence from the GDS3705 to open the door [*Virtual Number*Private PIN#].

Note: When local PIN type is set to private card PIN, users can also open the door by swiping their cards.

Local PIN to Open Door Schedule

This option needs to be enabled when GDS is connected to the wiegand. output device (RFID card reader for example)

Wiegand Output

This option is to be enabled when the GDS is the wiegand output device. (example: input device is a door controller)

Table 5: Door System Settings

Notes: Remote SIP phone needs a password (digits 0-9 only, ended with # key) matching the configuration on the web page to open the door (via DTMF).

GDS3705 support RFID for multiple users to open door, therefore every user has its own PIN. For an environment with 100 users and more, it’s difficult for the GDS3705 to manage all these users and a separate PC or Server should be involved for such kind of management and monitoring.

In environments with more than 100 users the GDS3705, another possibility would be to set one unified Local PIN for opening the door for all the users.

Using Alarm Out (COM 1) to Control a Second Door

Starting from firmware 1.0.0.41, the user can now set Alarm_Out (COM1) interface to control a second Door, in addition to the existing Locker/COM2 interface (controlling Door1).

This feature allows GDS3705 to control the operation of two doors via RFID, and local and remote PINs.

For example, a 3rd party Wiegand Input device or GDS3705 can be installed at Door2 with a related cable wired into the control GDS3705 installed at Door1. The Door1 and Door2 can be configured to be open by programmed RFID cards, and PINs either separately or both.

Figure 41: Alarm_Out1 Feature
  • Interface for Door Control (which Door can be OPEN):

If Alarm_Out (COM1) interface is set to control Door 2 opening, “ALMOUT1 Status” can be configured by choosing “Normal Open” or “Normal Close” based on the strike used.

Unlike the default COM2 which is designed for strike control and has three connecting sockets, COM1 only has two connecting sockets. Therefore correct lock mode has to be configured to make the strike work as expected.

For the above example, the GDS3705 is configured to control Door1 (wiring to COM2 interface); the 3rd party Wiegand Input is set to control Door2 (wiring to COM1 interface).

In case of a power loss then the DOOR STATUS when power is off will be depending on the following situations:

  • COM2 has three wiring PINs, corresponding to NO or NC accordingly. Therefore when connecting NC2 and COM2 (Fail Safe) the strike will open when power is lost and when using a NO2 strike (connecting COM2 and NO2) the door is “locked” when power is lost (Fail Secure).
  • COM1 (ALMOUT1) has only two PINs and NO ONLY. If the connected strike/lock is a NO strike, this means ALMOUT1 Status should be set to “Normal Open” then the door will be closed when power is lost, while if the strike connected is NC strike, and ALMOUT1 Status is set to “Normal Close” then the door will be open when power is lost.
  • Universal PIN for Operation of Doors:
Figure 42: Universal Local PIN

If Unified PIN (Universal PIN) is configured to open door, then which door can be controlled by the PIN is configured in the UI once “Unified PIN” is selected.

For example, like the above screenshot, if this universal PIN is set to open both Door1 and Door2, but due to the previous “Control Option” set to open Door1, and “Wiegand Control” set to open Door2, therefore the final result will be the INTERSECT result of both sets with condition qualified.

  • Remote PIN to Operation of Doors:

For remote PIN to open door, the PIN can be configured in example down below.

The PIN can be different for Door1 and Door2 and has to be configured correctly in related IP Phone which will be used to operate “One Key Open Door”.

If BOTH doors need to be opened at the same time, then both Door1 and Doo2 have to be configured with the exactly SAME password or PIN as DTMF open door.

Note

For enhanced security, When call is initiated from GDS then only the numbers existing in “Number Called When Door Bell Pressed”, “Account White Lists” or “Card Management” will be able to use DTMF PIN to open door remotely.

Figure 43: Remote PIN to Open Door
  • Private PIN or Card & Private PIN:
Figure 44: Right of Card and Private PIN

If using an RFID card or Private PIN to open door, then which door can be opened by the RFID card or Private PIN is configured via “Card Management”, see above screenshot.

Note

For all the settings, the final result of which door can be opened is the LOGIC INTERSECT OPERATION of ALL the sets of conditions qualified.

Please refer to our Open Door Flow chart for better understanding of how to configure and control 2 Doors operation: http://firmware.grandstream.com/GDS3710_opendoors_logic.pdf

Keep Door Open

Note: For security reasons, the SIP password is invisible on the web UI.

Display Name

The GDS3705 is an audio only device, unlike GDS3710, user cannot see who in at the door. Adding this “Display Name” will also allow user receiving calls from GDS3705 knowing where the call is coming from (e.g.: which door or extension the call is made), improve user experience when user is using a IP phone with LCD display.

Tel URI

Select “User=Phone” or “Enabled” from the dropdown list.

If the SIP account has an assigned PSTN telephone number, this field should be set to "User=Phone". Then a "User=Phone" parameter will be attached to the Request-Line and "TO" header in the SIP request to indicate the E.164 number. If set to "Enable", "Tel:" will be used instead of "SIP:" in the SIP request. The default setting is "Disable".

SIP Advanced Settings

Allows the SIP user's registration information to be cleared when the GDS3705 reboots. The SIP REGISTER message will contain “Expires: 0” to unbind the connection.

NAT Traversal

This parameter configures whether the NAT traversal mechanism is

activated. Users could select the mechanism from No, STUN, Keep-alive,

UPnP, Auto or VPN. The default setting is “No”.

If set to “STUN” and STUN server is configured, the GDS3705 will route according to the STUN server. If NAT type is Full Cone, Restricted Cone or Port-Restricted Cone, the unit will try to use public IP addresses and port

number in all the SIP&SDP messages.

The GDS will send empty SDP packet to the SIP server periodically to keep the NAT port open if it is configured to be “Keep-alive”. Configure this to be “No” if an outbound proxy is used. “STUN” cannot be used if the detected NAT is symmetric NAT. Set this to “VPN” if OpenVPN is used.

Enable SRTP

Enable SRTP mode based on your selection from the drop-down menu.

The default setting is “Disabled”, the two other modes are “Enabled but Not Forced” and “Enabled and Forced”.

Special Feature

Configures GDS settings to meet different vendors’ server requirements.

Users can choose from Standard, Broadsoft or Telefonica Spain.

The default setting is “Standard”.

Outbound Proxy Mode

In route: outbound proxy FQDN is placed in route header. This is used for the SIP Extension to notify the SIP server that the device is behind a NAT/Firewall.

Always sent to: SIP messages will always be sent to Outbound proxy.

Not in route: remove the Route header from SIP requests.

Validate Incoming Messages

Specifies if the device will check the incoming SIP messages caller ID and CSeq headers. If the message does not include the headers, it will be rejected. The default setting is "No".

Enable RTCP

This option allows 3rd party Service Provider or Cloud Solution to monitor the operation status of the GDS3705 by using related SIP Calls.

Notes:

  • If the correct key combination inputted, the last key input will play with a long tone, illustrating the correct key combination entered, then the GDS3705 will get into factory reset mode.
  • During the blinking time window, if the user does not finish the key combination operation, or pressed the wrong key combination, the GDS3705 will play short beep quickly three times illustrating error. Nothing will happen and the GDS3705 will get into normal booting process. User who wants to do hard factory reset has to perform the operation from the beginning again.

4. After 3 ~ 5 minutes the GDS3705 will finish performing the reset process, then the user can log into the GDS3705 web GUI using the shipped default password.

5. User must power OFF the GDS3705, unplug the Wiegand cable, power ON the GDS3705 again and make sure the GDS3705 is running correctly.

Restore to Factory Default Via SIP NOTIFY

1. Access your GDS3705 UI by entering its IP address in your favorite browser.

2. Go to Phone Settings # page.

3. Enable “Allow Reset Via SIP NOTIFY” by checking this option. (Default is disabled)

4. Once a SIP NOTIFY with “event: reset” is received, the GDS3705 will perform factory reset after authentication phase.

Note

Received SIP NOTIFY will be first challenged for authentication purpose before taking factory reset action.

The authentication can be done either using admin password (if no SIP account is configured) or via SIP account credentials (SIP User ID and Password).

Reset Factory Password Via Special Key Combination Operation

This feature allows customers to reset the device administrator password to factory default via keypad operation through some special key combination. When performing this operation, ONLY password will be reset back to factory default. All other setting or parameters will NOT be changed and will remain the same. This feature is specially designed for field engineers or technicians when dispatched in field but for some reason the administrator password is not available therefore not able to access the GDS37xx device to do the related maintenance.

Here are the steps to do such password reset operation via keypad:

Notes

  1. MAC address of the GDS3705 (check the sticker at back of the device)
  2. Default password of the GDS3705 (check the sticker at the back of the device)
  3. Correct decoding the last 6 MAC address into digits (refer to encoding rule)
  4. Correct decoding the default password into digits (refer to encoding rule)
  5. Finish keypad input within 1 minute

Operation Steps:

  1. When device is idle, input the special keypad combination with format: ***last_6_MAC**#
  2. Device will reach restore mode after correct digits in Step 1) entered. The backlight of keypad will flash quickly to tell operator the device is now in password reset/restore mode.
  3. Operator will enter the correct decoded default password ending with # with format: default_password_code# via the keypad within 60 seconds.
  4. If wrong code combination entered, the GDS3705 will beep with error sound (three short beeps) then exit the password reset mode, and the backlight will stop flashing.
  5. If the correct default password decoded entered within 60 seconds, GDS3705 will play a long beep sound (advising correct operation), the device will reboot itself automatically.
  6. If keypad entry time out (not finish the input within 60 seconds), the device will exit this password reset mode automatically and stop the backlight flashing.
  7. After successful password reset, operator will then be able to log into the GDS3705 webUI with default password, all the configuration inside the device will be the same and will NOT be changed.

For example:

Decoding the string into digits and write to paper before doing the operation:

Device with last 6 MAC address: 33DDDD

Decoding the last 6 MAC to digits would be: 334444

Default password is: xwpxz6AA

Decoding the default password to digits would be: 2423162426611
