QT-6600 Installation & Down Recovery Manual
The master plays an important role, such as controlling check tracking files. If the master
terminal goes down, the following undesirable condition results:
1) The check tracking processing (open check, close check. etc.) being performed cannot
be continued. (In case of Check Tracking master goes down.)
2) The receipt cannot be printed out to remote printers. (In case of Remote printer master
goes down.)
If the master terminal failed, therefore, the user should call the serviceman as soon as
possible.
With the QT-6600 system, the satellite terminal assumes that the master terminal is down
when it could not obtain any response to its inquiry. The master terminal is assumed to have
gone down in the following cases:
1) The power cable is disconnected from the outlet.
2) Trouble with the inline between the master and the satellite terminal.
3) Trouble with the master terminal hardware.
Note that the master terminal is not really down in the first two cases.
When a satellite detects the master terminal down, the satellite asks the operator by the
message below. If the operator of the satellite selects master removal, the satellite turn on
the "Master down" flag and broadcast all of the terminals (including backup master)
connected inline. After broadcasting this flag, all of the terminals do not access any check
tracking data to the master.
