Custom Electronics

This is a controller for a large paging system.  No off-the-shelf solution exactly met the clients unique combination of requirements which meant a custom piece of equipment needed to be designed and built.  The paging stations convert contact closure to RS422 for the long haul to the controller.  Crestron is programmed to control Radio Design Lab modules and relays.
