Power GDS370x using PSU

• To power the unit using PSU, use a multimeter to detect the polarity of your Power Supply, then connect GND to the negative pole and 12V to the positive pole of the PSU.

GETTING TO KNOW GDS370x

The GDS370x has an embedded Web server to respond to HTTP/HTTPS GET/POST requests. Embedded HTML pages allow users to configure the GDS370x through all available Web browsers in the internet.

Connecting GDS370x to Network with DHCP Server

The GDS370x by default has a DHCP client enabled, it will automatically get IP address from DHCP server.

Windows Platform

Two ways exist for Windows users to get access to the GDS370x:

UPnP

By default, the GDS370x has the UPnP feature turned ON. For customers using Windows network with UPnP turned on (most SOHO routers support UPnP), it is very easy to access the GDS370x:

1. Find the “Network” icon on the Windows Desktop.
2. Click the icon to get into the “Network”, the GDS370Xs will list as “Other Devices” shown like below. Refresh the pages if nothing is displayed. Otherwise, the UPnP may not be active in the network.

3. Click on the displayed icon of related GDS370x, the default browser (e.g.: Internet Explorer, Firefox, or Chrome) will open and connect directly to the login webpage.

GS Search

GS search is a program that is used to detect and capture the IP address of Grandstream devices. Below are instructions for using the “GS Search” utility tool:

• Download the GS Search utility tool from the Grandstream website using the following link: GS_Search

• Double click on the downloaded file and the search window will appear.
• Click on button to start the discovery for Grandstream devices.
• The detected devices will appear in the output field like below.

• Double click on a device to access its web GUI.

4. The detected devices will appear in the output field like below:

5. Double click the column of the detected GDS370x, and the browser will automatically open and show the device’s web configuration page.

6. Enter the administrator user name and password to access the Web Configuration Interface, the default admin username is “admin” and the default random password can be found at the sticker on the GDS3705.

Connect to the GDS370x using Static IP

If there is no DHCP server in the network, or the GDS370x does not get IP from the DHCP server, the user can connect the GDS370x to a computer directly, using static IP to configure the GDS370x.

1. The default IP, if no DHCP server, or DHCP request times out (after 3 minutes), is 192.168.1.168
2. Connect the Ethernet cable from GDS370x to the computer network port directly.
3. Configure the computer using Static IP: 192.168.1.XXX (1<XXX<255, except for 168) and configure the “Subnet mask” to “255.255.255.0”. Leave the “Default Gateway” to “Blank” like below:

4. Power on the GDS370x, using a PoE injector or external DC power.

5. Enter 192.168.1.168 in the address bar of the browser, and log in to the device with admin credentials. the default admin username is “admin” and the default random password can be found on the sticker on the GDS3705.

GDS370x APPLICATION SCENARIOS

The GDS370x Door System can be used in different scenarios. We will be using the GDS3705 Model as our testing unit.

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 GDS370x 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:

• GDS370x
• Grandstream IP Phones
• PoE Switch with related Cat5e/Cat6 wiring

Peering using SIP Server (UCM6XXX)

For large deployment, multiple GDS370x 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 GDS370x
• UCM6XX or another SIP Server
• Grandstream IP Phones
• PoE Switch with related Cat5e/Cat6 wiring
• Electronic Lock

GDS370x PERIPHERAL CONNECTIONS

Below is the illustration of GDS370x peripheral connections for related applications.

Alarm IN/OUT

Alarm_In could use any 3rd party Sensor (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.

Notes:

• The Alarm_In and Alarm_Out circuit for the GDS370x 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 GDS370x Alarm_In port will detect it and trigger the action and event.
• Higher voltage and wrong polarity connections are prohibited because this will damage the devices.

Protection Diode

When connecting the GDS370x 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.

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

Connection Examples

Below are examples, show how to use wiring on the back cover of the GDS370x 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.

Good Wiring Sample for Electric Strike and High-Power Device

Wiegand Module Wiring Examples

GDS370x 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 GDS370x.

Input example with 3^rd party power supply for Wiegand device

Make sure to connect the GND of the Wiegand device and the GDS370x 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 GDS370x and Wiegand device

If the power source is 12VDC, the Wiegand device can share the same power source as GDS370x. However, users need to check the max power consumption and the max capability of the power source.

If Wiegand device is using 5VDC, GDS370x Wiegand port can provide 5VDC with max 500mA to power up Wiegand device.

Output example with 3^rd party power supply for Wiegand device

When the Wiegand output of the GDS370x is connected, it acts as the signal receiver of the 3^rd 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

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 GDS370x
2. Pick up the Alarm Phone Call (if configured)
3. Open Door using a PIN (either public PIN or private PIN) for the GDS3705 Model only.

Once the alarm is triggered, the GDS370x 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.

GDS370x Connection: IN2 set as Normal Close and “Fail-Safe” Electric Strike using 3^rd Party Power Supply

GDS370x Connection: IN2 set as Normal Open and “Fail Secure” Electric Strike using 3^rd Party Power Supply

Open Door via GDS370x with or without a SIP Call

This feature needs related matching GDS370x firmware to work. The minimum firmware version needed:

• GDS370x: 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.

Door opening with SIP Call

When GSC3570 established a call with GDS370x, the screen will display the virtual open door button(s), and the user will press the button to open the door:

Door opening without SIP Call

At the GSC3570 idle screen, press “Monitor →Door system”, and the related GDS370x 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:

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

Secure Open Door via GDS370x and GSC3570 Peering

This secure open-door feature needs to include GSC3570 to make it a whole solution. The GDS370x/GSC3570 will be peering together in LAN/WAN via IP/SIP, and the door lock/strike will be wired to the GSC3570 alarm_Out port and controlled by GSC3570. This way the strike control is inside the building with enhanced security. Below is a setup example:

Note: Minimum firmware required for this to work:

• Outdoor Device: GDS370x 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 GDS370x. The GSC3570 controls the relay/strike/lock from inside the building (Unlike GDS370x 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).

GDS370x Web Configuration

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

GSC3570 Web Configuration

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

GDS370x HOME WEB PAGE

• Once the IP address of the GDS370x is entered on the user browser, the login web page will pop up allowing the user to configure the GDS370x 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.

GDS3705

GDS3702

GDS370x SETTINGS

Door System Settings

Users can configure system operations parameters, like input PIN for the door (GDS3705 Model only), and manage users’ settings.

Basic Settings

Door System Settings

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 3^rd 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.

• 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 3^rd 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:

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 Door2 have to be configured with the exactly SAME password or PIN as DTMF open door.

• Private PIN or Card & 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.

Keep Door Open

This feature allows users to set either an immediate or scheduled open door, this will allow usage scene like schools or similar private or public places where the door needs to keep open at specific time window and closed otherwise. Also handy for buildings or properties where a seminar needs to be hosted for some period or lunch breaks in a factory or company where the door keeps open and no access log required then back to locked with authorized entry after that, by default it’s disabled.

There are two modes under this section:

1. Immediate Open Door (One Time Only Action)

1. Access to GDS370x Web GUI using the using the shipped default password.
2. Navigate to Maintenance 🡪Reboot & Reset.
3. Select the reset type from Rest drop down menu and press reset button as displayed on the following screenshot.

Hard Factory Reset

Some users did not keep the revised password safely and forgot the changed password. Due to GDS370x did NOT have built-in reset button (Grandstream purposely designed this way to enhance security), this will make the GDS370x inaccessible even for the true owner who lost the changed password.

Below is a photo of the normal connection of the provided Wiegand cable.

To perform a hard factory reset to the GDS3705, please refer to the following steps:

1. Power OFF the GDS3705.
2. Take the provided Wiegand cable, and connect (or shorting) the related color wires as illustrated on the following picture. Please make sure the connection is correct and solid:

• Connect WHITE and BROWN cable together.
• Connect GREEN and ORANGE cable together.

3. Power ON the GDS3705. In about 10 seconds, the keypad LED lighting will change from solid lighting to blinking, the blinking time window is about 30 seconds. The user needs to enter the following key combination *0# while the LED is blinking.
Notes:

• If the correct key combination is 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.

Hard Factory Reset Using GS Search

The GDS3702 can be reset using the GS Search tool by following these steps :

1. Open the GS Search tool that can be downloaded from the Grandstream tools page.

2. Select the device in question, in our example it is the GDS3702, and then select Facility Device Password Recovery.

3. Perform the reset of the device by clicking the Reset button option, after providing the initial default password, found on a sticker on the unit.

Restore to Factory Default Via SIP NOTIFY

1. Access your GDS370x UI by entering its IP address in your favorite browser.

2. Go to the 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 GDS370x will perform factory reset after authentication phase.

The authentication can be done either using an 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 the password will be reset back to factory default. All other settings or parameters will NOT be changed and will remain the same. This feature is specially designed for field engineers or technicians when dispatched in the 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 a password reset operation via keypad:

Encoding Rules:

Alphabet A – Z mapping to digit 1 – 26 respectively, no difference in lower or up case.

A	B	C	D	E	F	J	H	I	G	K	L	M	N	O	P	Q	R	S	T	U	V	W	X	Y	Z
1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26

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

1. Enter ***334444**# via keypad, get into the password reset mode, the keypad backlight will flash quickly.
2. Within 60 seconds, enter 2423162426611#, the device will play one long beep then reboot itself.
3. Wait the device finishing boot up, log in the webUI using the default password, xwpxz6AA
