9. MASTER AND BACKUP MASTER ALTERNATION
The Backup Master Terminal can be changed to be used as the Master Terminal for an accident that
the Master Terminal becomes down, etc. And the Master Terminal can be changed to be used as
the Backup Master when it comes back from repair, etc.
To switch from the Backup Master Terminal function to the Master Terminal function
Disconnect the master terminal from the line.
When other terminals are in registration operation, finalize and cashier sign-off, operations should
be performed.
Since a transmission error occurs at this time, an inquiry job should be completed.
Change the backup master terminal address from 2 (BM) to 1 (M). (Therefore, the backup
master terminal will function as the master terminal.)
Refer to TERMINAL ID SETTING (Submode 77) on Chapter 4.
Delete the backup master terminal from the terminal connection table on the master terminal.
(Reprogramming is required.)
Refer to TERMINAL CONNECTION TABLE SETTING (Submode 69) on Chapter 4.
Download the terminal connection table.
The following files are guaranteed when the recovery process is performed. If a file is used in an-
other terminal when the master terminal goes down, however, data stored in the terminal is not
guaranteed.

• PC transmission information

The following files and data are lost when the master terminal goes down.

• Data which is being outputted from RKP 1 and 2.

• Files controlled locally on the master terminal

• Data in the files which are used by other terminals when the master terminal goes down.

11. TRANSMISSION ERROR
When a terminal makes an inquiry but a communication error occurs for some reason and the
inquiry to the other station is not possible, the message “IRC CONNECT ERR” (standard program:
programmable) is displayed on that terminal and operation is stopped.
When the Master Terminal cannot access the inquiring file because the Master Terminal is receiving
DLL data, the backup data is being updated between the Master and the Backup Master terminals,
etc., the message “MASTER IS BUSY” (standard program; programmable) is displayed and opera-
tion is stopped.
