The UP-3500 inter-register communication (IRC) system consists of one master machine and up to 31
satellite machines which are all interconnected by the local area network (LAN) to provide data transmission
among them. This system allows the manager to exercise centralized control over the satellites through the
master.

• One of the satellites may be used as a back-up master.

1)The message as shown below is displayed at the master which is engaged in IRC transmission.

ex.:

2)The machine number of the satellite communicating with the master is displayed at the master after

the start of IRC transmission.

ex.:

In this case, the machine number of the satellite is “000022.”

If an error occurs, a corresponding error message is displayed.
To clear an error message, touch the [CLEAR] key.
Some of the error messages are listed below as examples.

• This message prompts you to retry communication with the machine which you 

have failed to communicate.

• The target machine is busy.

• The specified clerk has signed on at another machine.

• The entered GLU code is in use.

• The GLU code or related file memory is not enough.

• Transmission error

• The clerk who entered a GLU code are not authorized.

• IRC initial downloading before resetting

• The back-up master doesn't reply to the request.

• The master doesn't reply to the request.

• Remote printer or external printer off-line error

• The target machine is turned off.

• T-LOG buffer is full.

• The file in the master and that in the satellite are not of the same type.

• The specified clerk code is not present in the master list.

• The entered code is not listed.

• The entry made is not valid.
