Setting Keyboard Baud Rate
This appendix provides instructions for setting the baud rate on keyboards
(Catalog No. 2706-NK1 or -NK2).
Before the 2706-NK1 or 2706-NK2 keyboards can be connected to the
DL20, the baud rate of the keyboard must match the display baud rate.
Displays are shipped from the factory with a baud rate of 9600. The
keyboard baud rate must be set to 9600 to work with a DL20.
Use the following procedures to change or verify the keyboard baud rate
1. Turn the keyboard over and slide the DIP switch access door open.
