Use the RS-232 interface to connect the MP72 to POS devices, host computers, or other devices with an available RS-232 port (for example, a com port). Then, use a second RS-232 cable (p/n CBA-R51-S16ZAR) to connect the MP72 Dual Cable Scanner/Scale AUX port to a scale-only port on the POS device.
The Dual Cable Scanner/Scale interface supports the industry-standard SASI scale-only protocol and communicates with a POS using a 9600 baud rate, 7 data bits, and even parity.
To set up the MP72 and Dual Cable Scanner/Scale:
Attach the RJ-45 modular connector of the RS-232 scanner interface cable to the POS port on the MP72.
Connect the other end of the interface cable to the serial scanner port on the host.
Attach the RJ-45 end of the RS-232 interface cable to AUX 2 on the MP72 (see Connector Ports).
Connect the other end of the cable to the scale-only port on the host.
Connect the power supply directly to the MP72.
Select the RS-232 scanner host type by scanning the appropriate barcode (see RS-232 Host Types). If your host does not display in the terminal-specific tables, refer to the host documentation to set communication parameters to match the host. To modify other parameter options, scan the appropriate barcodes in the MP72 Scanner Scale Barcode Programming Guide.
The protocol on this Dual Cable Scanner/Scale port is SASI.
Set the RS-232 device port configuration by scanning the appropriate barcode in the MP72 Scanner Scale Barcode Programming Guide.
