IRC Functions
Reports
Using IRC, you can generate consolidated X (read) or Z (reset) reports from any register in
the system. The report option screen allows you to select “All” or specify individual
register(s) for consolidation. See “X Reports” on page 94 or “Z Reports” on page 104 for
detailed report-taking instructions.
Busy Registers
Reports cannot be taken from registers that are busy (inside a transaction) or powered “OFF”.
The message “IRC NOT READY” will display if an attempt is made to communicate with a
register that is not available. The register number of the unavailable register will also display.
Best Practice: In IRC systems it is recommended to use only the key lock to turn the
register to “OFF”. You may wish to leave the power switch in the “ON” positon and use
the Power Switch cover (see page 13) to prevent the register from being turned off
inadvertently (and therefore not available for IRC functions.) With the power switch
“ON” you can turn the key to “OFF” so that reports and polling function will remain
available.
Device Sharing
Limited device sharing is available for remote printers and Datatran integrated payment
appliances and polling. Through IRC, traffic from satellite registers is sent to the Datatran or
printer that is attached to one of the registers in the network. In the case of polling, the PC
can access satellite registers through the connection to one of the registers.
Notes:
Caution:
The register where the shared device is connected will be momentarily busy when
traffic from a satellite register is communicated. The message “WORKING” will display
momentarily on the register that is connected to the shared device until the communication is
complete.
Best Practice:
In an IRC System where both a Datatran and remote printer are shared, it is
recommended that both devices be connected to the same register to reduce the amount of
cross-traffic between registers.
Feature Notes:
The Tracking File (Check File) cannot be shared through IRC. If check tracking is used, each
register will maintain its own file. Separate check files on individual registers can be polled
through IRC.
Other optional RS-232 devices, such as scales, scanners, pole displays, and coin dispensers
operate exclusively with the register to which they are connected, and cannot be shared.
