Connecting the interfaces

This section describes the pin assignments of the
interface sockets.
8.1

Serial interfaces

Note
There is a danger with long cable lengths (over 30 m)
that the bus nodes have different ground potentials. If
necessary, establish potential equalization between the
bus nodes with a separate cable.
Use a flexible cable with a cross-section of at least
2
for the potential equalization.
10 mm
All connections for the serial interfaces are available at
Serial 1. Serial 2 is set up for a connection of a serial
printer, the connections of both sockets are connected
internally.
