Frequently Asked Questions - GDS3702 GRANDSTREAM

How to connect the GDS3702 to power?

The GDS3702 can be powered via a PoE switch (IEEE 802.3af Class 3) by connecting an RJ45 Ethernet cable to the network port, or via a DC 12V/1A power adapter (not included) on the power connector. See the connection table for wiring.

What is the default IP address of the GDS3702?

By default, the GDS3702 uses DHCP. If no DHCP server is available after 5 minutes, the fallback IP address is 192.168.1.168. Use the GS_Search tool to find the assigned address.

How to access the web configuration interface?

Open a browser and enter https:// (default HTTPS port 443). Log in with username admin and the random password printed on the device sticker.

How to reset the GDS3702 to factory settings?

The manual does not specify the hardware reset procedure. Refer to the full user manual or contact Grandstream support. Generally, press and hold a reset button for 10 seconds.

Can the GDS3702 be used with an electric lock?

Yes, the GDS3702 has a relay output (NO2/COM2/NC2) for controlling an electric lock. Wiring depends on the lock type (fail-safe or fail-secure). Refer to the connection table and manual.

What are the wiring prerequisites for installation?

Use a Cat5e or Cat6 cable for Ethernet. For PoE power, pairs blue/blue-white (PoE_SP2) and brown/brown-white (PoE_SP1) must be connected. Follow the J2 and J3 connection table.

Does the GDS3702 work in cold weather?

Yes, its operating temperature range is -30°C to 60°C. Below -30°C, the device takes about 3 minutes to warm up before starting.

How to surface mount the GDS3702?

Drill holes according to the drilling template, fix the mounting bracket with screws and anchors, route the cable, connect wires (see connection table), then place the back cover and secure the device with security screws.

Can I use a power adapter instead of PoE?

Yes, option B requires a DC 12V/1A minimum source (not included). Connect positive (+) to 12V terminal and negative (-) to GND on connector J2. Ensure correct polarity.

Where to find the default password of the GDS3702?

The random password is printed on a sticker affixed to the device. It is also accessible via the GS_Search tool. Change it after first login under System Settings > User Management.

Note:

Needle nose plier highly recommended and 2.5mm flat screwdriver required (not provided). Stripping outer plastic shield of the cable in less than 2 inches suggested. Do NOT leave bare metal outside the socket by over stripping the inner plastic shield of the wires.

Step 3:

Make sure the "Back Cover Frame" is in place, the wired back cover panel is good. Flush the back cover panel piece with the whole back surface of device, tighten it using the screws provided.

Step 4:

Step 4:

Take out the two preinstalled anti-tamper screws using the hex key provided. Carefully align the GDS3702 to the metal bracket on wall, press and pull the GDS3702 down to the right position.
