PESA offers a wide variety of remote control panels that afford users easy access to switching functions through the 3500PRO or PERC2000 controllers. Control panels communicate with either system controller over a serial data bus called the PESA Remote Control Panel (RCP) bus. Each controller allows up to four RCP bus branches, and each branch allows multiple remote control panels to be daisy-chained for easy installation. Panels range from a simple push-button configuration to a complete status display control panel that allows multi-level, multi-bus operation. Monitor display panels are available for monitor and remote station labeling. Our port expanders allow the addition of up to 8 branches of the PESA Router Control (PRC) Bus or the serial remote control panel (RCP) bus.
