Job Done Examples
Example 2: Using the SEL-2032 as a Port Switch
Step 2. Connect the IRIG-B time source to the SEL-2032 IRIG-B
input. (You need to know if the time source has a modulated or
demodulated IRIG-B signal. Set IRIG setting accordingly.)
NOTE: You do not need to modify the
baud rate of Port 2 at the relay; the
SEL-2032 will match the baud rate
during auto-configuration.
Step 3. Connect the modem to Port 9 using cable SEL-C226, and
connect a telephone line to the phone line connector on the
modem.
Step 4. Connect the serial port on your computer to Port F on the
SEL-2032 with an SEL C234A cable.
Set the SEL-2032
Step 1. Issue the ACCESS and 2ACCESS commands and associated
passwords to go to Access Level 2.
Step 2. Use SET P F to set Port F parameters.
Step 3. Set Port 1 configuration communications options using the
SET P 1 command.
Step 4. Use SET A 1 to define a timed trigger condition in the form of
(Thh:mm:ss) to send a date message at a specific time once
each day to the relay connected to Port 1.
Step 5. Use the COPY 1 ALL command to copy Port 1 settings to the
other ports (2, 3, 4, 5, 6, and 7) with devices attached.
Step 6. Use SET P 9 to set Port 9 as a modem port.
Verify and Test All Communication Paths
Step 1. Use the STATUS command to check that the IRIG-B signal is
present and devices are connected to ports as expected.
Step 2. Check transparent communication with each port.
➢ Use the PORT n command to enter transparent
communication with Port n, where n is any port number
(1–16).
➢ Use <Ctrl+D> to end transparent communication.
Step 3. Check that all SEL relays are receiving the proper IRIG-B
signal from the SEL-2032, that all relays have their Port 2 set to
issue auto-messages, and that the relay Port 2 time-out is OFF.
➢ Enter Transparent Communication with each port,
Access Level 1, and issue the IRIG command.
➢ Issue the SHO command to check the relay’s AUTO
and TIME settings.
➢ Exit transparent communication using the default
disconnect sequence, <Ctrl+D>.
Step 4. Check that the SEL-2032 issues the correct date code to each
relay. Change the relay date to the wrong year; use the
TOGGLE command to issue the SEL-2032 date message.
Step 5. Check modem communication.
➢ Have someone call; the SEL-2032 modem should
answer by the fourth ring.
➢ The remote caller can enter transparent communication,
and you can watch the communication using front-
panel LEDs and the STATUS command.
