3. Use the up or down cursor keys to move the cursor to the parameter
to be changed. The current value for each parameter will be shown in
reverse video.
Important: Select both the SERIAL PORT (A or B) and the DEVICE
being set first (see Figure 9.1) since all other parameters are device
dependent.
4. To change a value after a parameter has been selected, press the left
or right cursor keys. The control scrolls through the available
parameter values as the left or right cursor key is pressed (or held).
5. To save the changes made to the communications parameters for a
specific peripheral device, press the {SAVE CHANGE} softkey. The
message “SAVE COMPLETED” is displayed. If the saved
parameters differ from the default parameters for that device, the
message “PARAMETERS DO NOT MATCH THE DEFAULTS”
appears beneath the parameters.
Important: You must save changes made to the parameter values for a
peripheral device before you select another device.
To restore the default parameters for a particular device, select that device
using the left or right cursor key, and press the {COPY DEFLTS} softkey.
The message “DEFAULTS LOADED” appears at the top of the screen.
To exit the device setup screen, press the exit {

device setup screen becomes your current settings.
PORT (setting of input/output port)
The 9/240, 9/260, 9/290 and 9/440 controls have two communication
ports: port A and port B. The 9/230 control uses only port B. This
parameter selects which of the two ports is going to be modified. When
you select port A, you see the letter “A” displays; and when you select port
B, you see the letter “B” displays.
All of the following parameters can be set independently for each
communication port (A or B).
