I have Just Installed a New XP-GT or XP-GTR Controller but it's Status is Shown as Down in Device List

After installing the new XP-GT or XP-GTR controller, the controller status in Device List is shown as "Down".

The controller failed to establish communication with the software.

• XP-GT3200
• XP-GT3500
• XP-GTR1200
• XP-GTR1500

There are several potential causes which contributes to the same symptoms:

Connection Settings:

1. Controller is not connected to a network switch / router using a network cable if it is to be connected via LAN connection.
2. The network router / switch has not been powered up.
3. The network cable used is in faulty condition

Network Settings:

1. Dynamic IP Address is used for the Server PC's IP Address, thus the controller is unable to establish communication with the Server PC as a result of IP Address changes.
2. IP Address conflict.
3. Incorrect network configurations was set in the Network Parameters in the controller's settings.
4. Incorrect Remote IP Address / Controller Model No. / Door Unit No was set in the software server.
5. The controller communication is blocked by firewall

Step 2: If the Uplink Communication icon is absent, then it means that the controller failed to communicate with the software, users should then proceed with the remainder of this article.

• General Troubleshooting steps for LAN Communication:

Step 1: Check and ensure that the controller is connected to a network switch / router, and that the network switch / router is powered on and in running condition.

Step 2: Check and ensure that the network cable used is in good, working condition. Users are advised to test the connectivity of the cable by using a network cable tester.

Step 3: Before assigning any IP Address, users should ensure that the IP Address does not conflict with other devices. To do that, users must try to ping the IP Address before hand via Windows Command Prompt.

Step 4: To check whether the Server PC's IP Address is static or dynamic,

 1. Go to Network Connections window, right-click on the Ethernet and select Properties.

 2. The Ethernet Properties window will then be shown. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.

3. The Internet Protocol Version 4 (TCP/IPv4) Properties window will be shown. Ensure that the Use the following IP address checkbox is ticked, enter IP address of the Server PC and click OK.

Step 5: Users should also check and ensure that the Network Parameters configured on the controller LCD screen matches with the configuration in the software.

• To allow the application to communicate through Windows Firewall:

Step 1: Users must allow the application (xPortal software) to communicate through the Windows Firewall.
