Module Bus Interconnection
All the extending modules, except for the tamper switch, are 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 include an 80 mm long bus cable. (9155034)
It is possible to order separate bus cables of the length of 1 m, 3 m or 5 m (Part No.
), which are intended for remote module 9155050/9155054/9155055 respectively
installations. Typically, they help install an RFID card reader on the opposite side of
the wall on which is installed. This cable may only be used once on the 2N IP Style
®
bus. The total length of all the bus cables used in these extended installations may not
exceed 7 m.
