Serial Port Communications
and Commands
Overview
Various serial ports are available in the SEL-351A Relay:
Connect the serial port to a computer serial port for local communications or
to a modem for remote communications. Other devices useful for
communications include the SEL PRTU, SEL-2032, SEL-2030, and
SEL-2020 Communications Processors, and SEL DTA2 Display/Transducer
Adapter. You can use a variety of terminal emulation programs on your
personal computer to communicate with the relay. For the best display, use
VT-100 terminal emulation or the closest variation.
The default settings for all serial ports are:
➤ Baud Rate = 2400
➤ Data Bits = 8
➤ Parity = N
➤ Stop Bits = 1
To change the port settings, use the SET P command (see Section 9: Setting
the Relay) or the front-panel {SET} pushbutton.
