Computer
If the computer is part of a loop or network, each computer should have its
number
own, unique number.

Type
Enter whether the computer functions as "master" or "slave". The "master" is
the computer which controls communication. All the other computers in the
loop (L) or network (N) should be set as "slave".
Baud rate
All the computers in a loop should have the same Baud rate setting. The loop
communication normally works at 2400Bd. If a modem of 1200Bd is used, all
the other computers in the loop should also be set to 1200Bd.
Comm. R...,T .....
Communication counters with loop communication for receive (Receive) and
transmit (Transmit). These counters can be used to trace faulty
communication connections. In this case set all the counters on all the
computers to "0". Normally these counters increase simultaneously.
Communication has failed between the last computer where the counters are
increasing simultaneously, and the first computer where the counters are not
increasing at the same speed.
Network status
If several computers are connected via a network, the network status can be
controlled. The network status is a value between 0 and 5. If the value is 5,
the connection is in order. Every other value (0, 1, 2, 3 or 4) indicates that
the network connection is not (yet) in order.
