Ajax Alarm system integration UART
do you know if it is possible to integrate LM5 with Ajax Alarm system by using their uartBridge module?
Im not familiar with uart protocol but what I understand that it uses rs232

Here is link to uartBridge protocol documentation:

I dont have Ajax yet but I want to know if it is possible to integrate ( at least in theory)
The protocol description is missing there (or I can't see it). There's no CRC, which is dangerous (or maybe it's in layer below but it's not visible from the provided PDF).

I see +5V at the pinout. Does it mean it's TTL RS232? I'm just guessing)
LM5Lp, firmware: 2018.08.22, FlashSYS v2, ARMv7 Processor rev 5 (v7l), kernel 4.4.151

It's not possible to connect this directly to LM. You will need a USB-UART adapter. The protocol itself looks simple enough - ASCII lines terminated by \r\n
Ok and thanks! Now I know that it can be done. It is only matter of scripting that functionally.
