This option can only be changed if your computer or terminal is attached to the
serial port of the bottommost Port Card in the Affinity chassis (the card installed in
the lowest occupied slot; see
Section 2.3
for slot numbering). For instance, if you
are using a computer attached to the serial port of the Port Card in slot 3, this
operation will work if there are no other Port Cards in slots 1 and 2. But if there’s a
card in slot 1 or 2 or both, you’ll have to disconnect your serial cable and attach it
to the lowest-numbered card (the card in slot 1 if there is one, the card in slot 2
otherwise) in order for this to work.
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
attached Port Card (see
Section 7.2.6
), then cycle power to the Affinity to
distribute the change to all of the other Port Cards in the unit.

Change the setting of this option to change the baud rate (data rate) that the
ServSwitch Affinity uses on its serial ports. Before you select it, this option will show
the current speed of the attached Port Card’s serial port as either “9600” or
“57,600” (bps). You will 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 to match that of the
Affinity’s Port Card. (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 Affinity, 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.
