When the open store operation is performed at the master, the IRC system is opened. POS can send AT
command by this job. This function controls a modem, but doesn't have control over registration and T-LOG.
The procedure for the open store operation is as follows.
Select “OPEN STORE” from the OPXZ mode window and press
the
e
key.
• You can also perform the open store operation at each satellite.
• The open store operation cannot be performed at any machines whose terminal numbers have
not been programmed.
• When a transmission error occurs while the open store operation is being performed, the open
store operation is regarded as normally terminated if the system retry function* has been
disabled by programming. When the master has been programmed to enable the system retry
function, it displays the machine number of the satellite that has encountered the error.
Selecting the displayed machine number will display a prompt to retry the open store operation.
* For the system retry function, see page 63–64.
