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.
