This option can only be changed if your computer or terminal is attached to the
serial port of port board 1 (the bottom board that includes CPU ports 1
through 4—see Figure 2-3 in Section 2.4 for board numbering).
The serial options menu displays the currently configured starting-CPU number
in option 1. To change option 1 (starting CPU), press 1; you’ll see this prompt:
Enter the starting cpu number →
Type the new number and press [Enter]. The serial options menu will be displayed
again. Use option 7 to permanently save this change to the flash memory of the
port board (see Section 7.2.6), then cycle power to the Switch to distribute the
change to all of the other port boards in the Switch.

Change the setting of this option to change the baud rate (data rate) of the Matrix
ServSwitch port board you are communicating with. Before you select it, this
option will show the current speed of the port board’s serial port as either “9600”
or “57,600” (bps). You can change this rate just by pressing 2 to select this option,
so be careful about doing that. After you do select this option, these messages will
appear (still at the old data rate):
Baud rate changed to 9600 [or 57,600]
Set baud rate of your terminal to 9600 [or 57,600] and press
return
If you’re using a terminal or a better communication program, you will be able to
change your terminal’s or communication program’s data rate on the fly to match
that of the Switch’s port board. (Refer to the comm program’s manual or online
help for instructions on doing this.) If you’re using Windows Hyperterminal,
however, you’ll need to temporarily disconnect from the Switch, change the data
rate, then reconnect:
1. Select “Disconnect” from the “Call” pulldown menu.
2. Select “Properties” from the “File” pulldown menu.
3. Select “Configure” and change the data rate in the field labeled “Baud rate.”
4. Press “OK” to save your new PC data rate.
5. Select “Connect” from the “Call” pulldown menu.
Once you’ve changed the data rate on your end, press [Enter]. The serial
options menu will be displayed again, at the new port-board data rate. Use option 7
to permanently save this change to the port board’s flash memory (see
Section 7.2.6).
