I hope my posting is ok and not out of line!
We have/are developing a range of IP controllers and would be happy to work with any one who maybe interested in using them with
The unit i think maybe of interest is called T1, this has
4x RS232 ports
1x RS485 port
6x IR outputs
We also make devices that sit on he RS485 such as relay boxes, audio switchers and dimmers (dimmers are coming soon)
All units are euro DIN mount but can be put into desk top or rack mount style boxes.
please PM me if you would like to work with us.
