I have a customer who wants to add security to their 2 passenger cars with SPEC 60 (MRQ) controls. I know that the calls are serial and this will require some hardware to make it work. The existing job prints are missing some pages and I don't know for sure if there was anything in those pages that would have shown board addressing and wiring for the serial boards needed. I dug up an Otis article on how to program card reader operation for this type of equipment but I don't know if I can order a kit from Unitec for this project or if I have to piece meal it all together? Does anyone have a set of prints from a job that had security? I think I can use RS5 boards but I don't know what they should be addressed to either. Anyone's help would be greatly appreciated.
