PORT MANAGER SWITCHES
6. Define the Site I.D. message. The Site I.D. allows the user to denote the
location or name of the PM Switch unit. The Site I.D. cannot include
nonprintable ASCII codes such as [NUL] (the null character) and [LF]
(the line-feed character).
a) Type “/F” and press [Enter]. The PM Switch will prompt the user to
enter the Site I.D. Key in the desired Site I.D. and press [Enter]. The
Site I.D. can be up to 32 characters long.
b) To display the Site I.D., type “/J” and press [Enter].
c) Note that the Site I.D. will be cleared when the PM Switch is
initialized.
This completes the introductory overview of the PM Switch unit. After you
have determined that the unit is operating properly, configure the
PM Switch as described in
Chapter 4 .
This chapter describes the procedures for installing the Port Manager Switch
and connecting devices to the unit.
4.1 Setting the SETUP Switch
When the PM Switch is shipped from the factory, all of the positions of its
SETUP DIP switch are set to
down
, which means the PM Switch is configured
to default to 9600 bps, 8 data bits, no parity, DTR flow control, verbose
command response, and no command echo (half-duplex operation). These
factory-default switch settings are compatible with most applications. If the
default settings are not compatible with your application, change the switch
settings as described in the following subsections.
The SETUP Switch should be set to match the communication parameters
used by the device attached to Port 1. This assures that you can access the PM
Switch if the unit is initialized to default parameters.
