Help programming

[glaso 1]

Hi:

I've been searching for a while for ways to integrate HC2 to different alarm systems. Right now I am working with a DSC PC1616 panel with a Envisalink 3 interface

They provide a TPI (third party interface) programming guide (attached), but I can't get it to work.

My programming skills are pretty rudimentary and when they start talking about binary, hex and ASCII commands I get really confused.

I managed to open a TCP socket from terminal app on a MAC, but can't manage to send commands to the alarm panel. I always receive a "syntax error message" (50202029).

Could someone help me with a few sample strings to, for example, arm or disarm the alarm, in order to understand the protocol and start working on a virtual device to fully integrate the alarm to HC2?

Example: Partition arm control - with code

Command code: 033 (ASCII 30 33 33)

Partition: 1 (ASCII 31)

User Code: 1234 (ASCII 31 32 33 34)

Checksum (according to my inexperienced calculation): 0x1F1 (ASCII 66 31)

I tried the following string with no luck (always received "syntax error" message):

303333313132333466310D0A

30:33:33:31:31:32:33:34:66:31:0D:0A

30333331313233346631

30:33:33:31:31:32:33:34:66:31

If someone could point me in the right direction would be great in order to start working on the integration of DSC panels.

Thanks!!

Does your system have anything like API ?

Sorry, forgot to add the attachment, now is included in the original post.

Its a TPI (third party interface) programming guide. The closest to an API I was able to find

Found the answer

the code shouldn't be converted to ASCII (just to make de checksum)

The correct string was:

0331123491

Mac terminal adds the line feed (LF) 0A automatically, so it is necessary to add the CR (0D) to the end of the string. on terminal is control + V

Now I want to send the string directly from HC2, but I can't figure how to open the TCP socket from HC2 using Lua. Anyone?
