2.3.1 The bus
The bus is a serial communication channel, used for exchanging data between the control panel
and the peripherals. The protocol in use by the bus is ForceCom (PIMA proprietary).
Use four 0.5mm (24 Gauge (AWG)) wires for the bus. The maximum bus length is
500m, including all peripherals and keypads.
Connect the wires using the numbers 1-4, where terminal #1 on the control panel
connects to the same terminal on the peripheral, and so on.
