VisuaLink 128/384 Engineering Guide Chapter 1
1.4 Communication Format
Communication between a console and VisuaLink 128/384 is done in a start-stop synchronization of the
following format.
Data Format
Data Length: 7, 8 bit ASCII code
Stop Bit: 1 bit
Parity: Even, Odd, NONE parity
Baud: 1200, 2400, 4800, 9600bps
Note: Default setting for VisuaLink is 9600, 8, none, 1.
To change the default setting use the SSPR command.
A: Conne ct terminal to VisuaLink Serial 2
B: Set terminal application to:
Baud: 9600
Parity: Even
Bit: 8
Stopbit: 1
C: Calculate the Baud, Parity, and Bit
D: Set system parameter command for the appropriate setting
Example: SSPR 168=21
Means: Your VL in now set up for 2400, 8, EVEN, 1
E: Reset the VL.
