I got a Paradox 1738 Spectra v2.10 Alarm Panel that I need to interface with.
Thanks to the info found in this thread: https://forum.arduino.cc/index.php?topic=101632.30

I managed to interface directly on the serial port @9600 bauds. Other users seems to get 37 bytes packets, but in my case, I only get 4 bytes/event.

Think I decoded part of it correctly, but is there more info on that 4 bytes version of the Paradox serial protocol?

Updating the thread in case someone else encounters this version of the Paradox protocol.

I managed to get what I needed of of it by walking the zone and setting off the alarm on purpose.
Still to be done would be analysing the Status 1st byte... but all I need for now is keeping a log of events + reports of alarms/watch some users lock/unlocks.

Hi MarioT,

thanks a lot for sharing this information! I have a Spectra 1728 and have just started to log the packets, and you helped a lot on how i can decode them.

Hi,
also thank you for sharing. I have Spectra 1738 too. I am going to do something with it but had no time yet. However, your info could be useful for me. Thx.
