5.11 Connecting a Barcode Scanner
The
Counterpart
will accept a barcode scanner connected to the unit. In order to use a scanner, you must set the
specifications of the
Counterpart
scale to recognize the scanner to the appropriate port and, in some cases, do the
setup on the scanner required by the scanner manufacturer.
The scanner allows non-contact, instantaneous, and accurate input of unit weight, tare weight, and ID code.
QD2100 Barcode Scanner
If you are using the Quickscan QD2100 barcode scanner sold by Rice Lake Weighing Systems, you can set up the
scanner by connecting the scanner (PN121495) to the RS-232 port on the
Counterpart
CPU board. Plug connector
with three wires into serial port 2 (J4) and plug with one wire into DIGIO (J3). Connections between the barcode
scanner and Counterpart should be wired as shown in Table 5-3.

The default baud rate is set for 9600 for both
Counterpart
and the scanner.
To set up barcode scanner parameters:
1. Navigate through the menu Setup >> Config >> Serial.
2. Set up the selected Port, J5 (Port 1) or J4 (Port 2) for the scanner.
3. Follow through and set up the various parameters such as 9600 baud, 8 bits, 1 stop bit, none parity.
4. Headers are set to
ON
under scanner sub-menu when needing to have headers for IDs, tare and unit
weights.
5. If the header is set to
OFF
, the
Counterpart
assumes that all scanned items are ID codes and part numbers.
Note
ID codes are not functional when scanning ID codes.
