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:Connect 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

00: 7 bit EVEN STOP

011 7 bit ODD STOP

10: 8 bit EVEN STOP

11: 8 bit NONE STOP

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.
