The FC36M & FC36MV parameter display/programming (Commander) module comprises a PIC microcontroller interfaced to a 20 by 2 line alphanumeric liquid crystal display (LCD). It is linked to the FC36M & MV firing module via RJ45 connectors. The programming module can be plugged and unplugged from the firing card before or after power-up.

The programming module is small and compact, with maximum overall dimensions of 175mm x 50mm x 33 mm depth, and can be panel mounted or hand held. Panel cut-out should be 168mm x 45mm.

Data transmission between the parameter Commander module and the firing card is via two-wire serial communication using the Universal Synchronous Asynchronous Receiver Transmitter (USART) peripheral in each microcontroller.

Programmed parameter values and mode settings are retained in EEPROM memory of the firing card and recovered on power-up.
