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
E
ven parity.
