Hi Folks, I'm trying to interface my Solution Ultima 880 to my PC. I have already done it with the ALink software but know I want to monitor the panel in realtime from the WWW. I figured that if I make the PC emulate a codepad I should be able to have realtime updates.

From Bosch's manual I can see that the codepad uses a clock and a data line. This labeling makes me think that it could be using I2C, but the electrical characteristics of I2C wouldn't work for the lengths that the codepad support.

Any ideas on which bus standard and protocol Bosch/EDM is using?

Thanks

Cat
