Hi,I have a Comfort system fully installed and working really well for a number of years. I need to add another keypad to the system but cant get a direct RS485 cable to the location. I do have IP network connectivity so I have bought a pair of RS485 to IP transceivers. Can someone let me know the RS485 settings in Comfort for Baud Rate, Parity etc so that I can \"tunnel\" the RS485 over Ethernet? Thanks in advance!

The Rs485 parameters are
  • Baud rate 9600
  • 8 data bits, 1 stop bit
  • No parity
Please update us if you can get it working and which device you are using. It may be an interesting solution

I am trying with another pair of rs485 devices which apparently support transparent tunnelling.
On the comfort bus, is it half duplex? I think it must be due to the single pair of A and B but I could do with it being confirmed
Thanks!

The communications  is 1/2 duplex
