There are five different detectors connected to the data bus, all
together controlling 13 separate track sections. In order to display
and exploit the data there are used:

four single display devices RCA-1 displaying the data from one
section each,

one 24-fold display device RCA-24, displaying the data from all 13
track sections,

one RailCom PC interface RC-Link.
Bus line
For technical reasons, there are two wires with a diameter of minimum
0,10 mm² mandatory as a bus line for the communication between
detectors, display devices and PC interfaces (lines A and B). In order to
minimise the vulnerability towards disturbances from other cables, the
two wires should be twisted. It is recommended to use twin wire (e.g.
LiYz, 2x0,19 mm², red-brown, item no. 73-30037)
The bus line has to be looped through from one to the other device.
When connecting them the lines A and B always have to be assigned to
the corresponding connection points A and B of the devices.
