Hardware Requirements

The barcode scanner must support an RS-232 output interface for use in the RF FMS. The barcode scanner serial output must

support standard RS-232 levels of ±3V DC to ±12V DC. Logic level or TTL output signals are not supported by the RF FMS. The

barcode scanner is connected to the RF FMS Dispense Keypad via the external printer RS-232 port with DSUB9 connector

on the bottom of the Standalone Keypad. The RS-232 port on the Standalone Keypad is configured for a Device Circuit-

Terminating Equipment (DCE) pin out configuration. A null modem adapter is required for barcode scanners that are also

terminated with a DCE pin out configuration. The required RS-232 port settings for the barcode scanner input are as follows:

Baud Rate 9600 Baud

Data Bits 8 bits

Stop Bits 1 bit

Parity Odd

Hardware Flow Control None

The data output of the barcode scanner is required to be a stream of ASCII characters representing the barcode. To identify

the end of transmission, the stream of ASCII characters should be terminated by a carriage return and line feed ASCII

characters.

• Barcode Scanner cannot be used with Remote Printer.

• External Printer setting must be set to NO.
