 Bigger Bigger  Smaller Smaller  Reset Reset

Hello, I am playing with Spectra 1738 panel. Connected the serial port to my Debian server using RS232 to USB converter. The boud rate I am using is 9600. But can see only 7 bytes sent when an event is triggered. It seems the bytes differ from the ones Mauzer described.
Here is a sample of what I am dumping:
(the first value is the time i inserted - not from the Paradox system)
1381052775      11      5b      b0      8       1       5b      b0
1381052775      11      5b      b0      8       11      5b      b0
1381052795      81      60      0       8       1       60      0
1381052795      81      60      0       8       11      60      0
1381052799      41      60      0       8       1       60      0
1381052799      41      60      0       8       11      60      0

It seems the 5th byte reports sensor state.

Just in case anyone is still looking for this, you can find the protocol doc for the Digiplex online. The file name is, "DIGIPLEX-ASCII-EP00-eng.pdf". (Sans quotes.)

For example: http://www.elektro-mahl.cz/dokumenty/DIGIPLEX/DIGIPLEX-ASCII-EP00-eng.pdf

You need to have the PRT3 module in, and configured to, "Home Automation," mode. Hope this helps. smiley
