interconnected via a bus. The bus starts on the basic unit and goes over all the
modules. The order of modules on the bus is irrelevant. And it also irrelevant which bus
connector on the module is used as the input and which is used as the output.
The modules include a 220 mm long interconnecting cable; the Wiegand (9155037)
and I/O modules (9155034) include an 80 mm long interconnecting cable.
You can order a separate 1 m long bus cable (9155050) for remote installation of the
modules. Typically, it helps install an RFID card reader on the
