NOTE
Communication parameters (data rate, parity, etc.) can also be
individually selected for each PM Switch port by accessing the
Command Mode and invoking the /P command as described in
Section
5.3.4 . However, when the PM Switch is initialized, these parameters will
return to the settings specified by the current SETUP switch
configuration.
If you change the configuration of the SETUP switch while the unit is
powered ON, the new configuration will not take effect until you initialize
the PM Switch. You can do this by sending the unit the /I command, or
you can press and hold the unit’s CLEAR and SET buttons, release the
CLEAR button, then release the SET button.
Positions 6 and 8 of the SETUP switch are reservedc for future use.

Use positions 1 through 3 of the SETUP switch to select the default data rate
for all PM Switch ports. The default data rate must match the data rate your
control device will use when communicating with the PM Switch. If the
control device will communicate across a modem link, select a default data
rate that is compatible with the modem.
After the PM Switch has been installed, you can also use the port-
configuration command /P to select individual data rates for each port.
