Step 2 - Setting Program
Parameters and Verifying Host
Connection
Now you need to turn on the NCR RealScan 7882. After making any necessary
program changes, scan a few tags to verify that the RealScan 7882 is communicating
with the host terminal.
Turning on the RealScan 7882
The RealScan 7882 does not have an On/Off switch. Use the circuit breaker switch in
the checkstand that supplies power to the unit as the On/Off switch. Put this switch in
the On position.
Programming the Communication Parameters
Caution: Some host terminals can corrupt the RealScan 7882 program if they are
running and are connected to the RealScan 7882 while you are making program
changes. Either turn off the host terminal or disconnect the interface cable before
scanning any programming tags.
If the Interface Cable is provided as a kit rather than being included with the
RealScan 7882, you can set the communication parameters by scanning the bar code on
the label on the cable package. Standard defaults are set for most RS-232 or OCIA
cables. If the cable is for a specific host terminal, all the necessary parameters required
for that host terminal are set. The bar code label on the Interface Cable package must
be the first bar code scanned after applying power to the RealScan 7882.
If the Interface Cable came with the RealScan 7882, the communication parameters are
probably correct and you should not need to make any changes to these parameters.
However, if the RealScan 7882 does not communicate with the host terminal, scan the
appropriate tag from the following set of communication protocol tags.
Note: When scanning bar codes on the following pages, be sure to completely cover all
bar codes except the one you are scanning.
