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.
