GE PB3-POS-RP user manual Protocol

SW2 - Switches 5-8

Switches 5-8 on SW2 are used to modify the communication transfer protocol on Port 2 of the PB3 should the POS device you are using require it. The protocol listed here consists of 3 user definable settings: The Start Bit, The Stop Bit, and Parity. These can be expressed as follows:

•Stop Bit: 7 or 8-bit ASCII

•Stop Bit: 1 or 2-Stop bits

•Parity: Odd, Even, or None

In the following table 8,1,E would translate to 8-start bits, 1-stop bit, and Even parity.
