power. The lithium-type battery has an expected life of 10 years. The internal
clock is accurate to within 1 minute per year with power applied. You can
reset the clock and calendar using the SEL-2032 TIME and DATE
commands.
Distributes IRIG-B Through Ports 1–16
The SEL-2032 distributes a demodulated IRIG-B signal through all of its 16
rear ports. You can use this to synchronize any type of device, such as a relay,
fault recorder, or meter, that can decode the IRIG-B signal. To use this feature,
you need only to connect the device to the desired SEL-2032 port using a
special cable designed for both communication and IRIG-B signal. For
devices that do not have an IRIG-B port or cannot decode the IRIG-B signal,
the SEL-2032 can send time and date messages on a periodic or time basis to
keep their clocks synchronized.

Settings
SET command variations allow you to configure and control SEL-2032
operation. See Section 7: Settings for more detailed information about this
group of commands.
SET P—Port Configuration
You can use the SET P settings to establish each port’s configuration and
communication parameters. The configuration options are designed to make
the SEL-2032 compatible with almost any device that has an EIA-232 port.
This is the only setting command required to use the SEL-2032 as a port
switch.
You should use the SET P command to configure each port. The first prompt
from the SEL-2032 asks you to identify the type of device connected to the
port. Port F can only be configured as a Master port. Ports 17 and 18
correspond to the protocol cards and are set automatically to match the
installed card.
SET A—Auto-Message Settings
Use SET A settings to control the following automatic messaging settings:
➤ Initialization message to be sent to the IED when
communication begins
➤ Fast Operate message enable
➤ Outgoing messages for control and data collection
➤ Size of the User region
SET U—User-Defined Commands
Use the SET U command (Ports 1–16) to create user-defined commands that
other devices send to the SEL-2032. You can also use this setting to trigger
action from selected SEL relay auto-messages (Event, Status, and Group). The
user-defined commands can supplement or replace the preprogrammed
