CBUS Interface with RS485 device

Hi,

I was wondering if anyone knows how I can connect a R485 device to CBUS and control it via C-Touch..?

The unit Im trying to connect to is a IAS Smartzone unit for controlling air con...

I have been looking at the possibility of making my own PCB that will convert RS232 to RS485, but I?m sure there is an easier way of doing this? I hope.

Any ideas, suggestions, experience would be much appreciated

Thanks,

NW

 

I have some robust 232 - 485 converters. Let me know if I can assist. They are probably cheaper ex-factory.

I have both kinds on hand .... let me know if I can help.

 

You will only be re-inventing the wheel making your own PCB. Get a converter, there are plenty on the market.

You can also try e-bay for some if you are on a budget

You will also need the RS232/485 commands for the AC unit and a means of sending those commands based on C-Bus messages. The PACA works well for this purpose. If your C-Touch is the colour version it has serial comms (to other systems) built in

 

Were you happy with the performance of the smith type of converter. I purchased a couple a while ago to use with the sonance touch screens but havent had time to play with them as of yet.

 

One is the small basic model for tight spaces and the other is highly-robust and heavily protected model for long endurance. They all have the same basic functions.
