Go to the DSC test page at http://www.dsc.com/iptesting/ and setup your T-Link with an IP address of 209.82.42.121 and port number 3061. Enter any 4 digit account code into your T-Link and DSC panel. Prefix the account code with zeros in your panel programming. Carry out some tests and if possible, test every device on your system to make sure they all communicate correctly with the server.

Programming your DSC TL-150

1. Enter "tl-150" into the URL bar of your browser and enter the username of "admin" and pasword "admin" when requested in order to access the web interface of the device.

2. From the main page, choOse the "Config" hyperlink in the top right corner and you will be presented with a number of programmable options. The options will vary slightly depending on your firmware version.

3. DRL-IP Reporting Address. Enter the IP address provided to you by youralarm.com.

4. Receiver Port Number. Change the value to the one provided by youralarm.com (usually 3061 or 6000)

5. Encryption Key. Enter 32 zeros to disable encryption.

6. Account Code. Enter your assigned 4 digit account code. You should also program the four digit account code into your alarm panel and prefix it with 6 zeros. Example 0000001234

7. Test Transmission Period. Enter 1 to enable a supervision heartbeat every 15 minutes.

That's all there is to it. There is no panel programming required other than the account code.

IMPORTANT: Please note that there is a known issue with DSC IP communicators whereby they stop working correctly if the network router changes IP address or reboots for any reason. The built in web server is also very inconsistent. For these reasons, it is essential that you have your system communicate daily test signals to the monitoring center so that any problems can be picked up quickly.
