In Case Of Error - Casio V-REGI Series Reference Manual

5.4. In case of Error

PLU register operation will send stock information to Master. In case of communication error,
the "not-yet-send-data" will be kept and will do automatic retry. Operator does not care
communication error.
"PLU with Stock Check" checks Check Master stock data and response whether the stock is
zero or less, then communication retrying may slowdown PLU operation. If communication
is not available, PLU operation cannot check but can register without check.
Shared Stock uses Shared Check Tracking, then also Check Master down may happen when
check operation (for New, NB, Fin) or non-check tracking finalize (for Invoice number).
Even if Check Master is cut, Shared Stock communication is not related Check Tracking, then
Stock data will send to Stock Master even if Check Master down.
Once used Shared Stock (or Shared Check Tracking) for demonstration or installation,
changing of terminal property (Master/Satellite) may cause wrong transmission
"not-yet-send-data". Please INIT2 if change terminal property.
Important
When you perform "Remove check master", check tracking function will be changed to

the stand alone mode but shared stock control function will try to continue work with
shared stock master terminal.
If you change settings for shared check tracking after you have performed actual

registration of stock control such as for demo, there is a possibility to remain data
internally which were not updated stock master.
To clearing up such data, please perform Init2 to clear up internal work data.
