PORT 1 Settings
(Serial Port Command SET P 1 and Front Panel)
Protocol Settings (See Below)
Protocol (SEL, LMD, DNP, DNPE) PROTO =
Protocol Settings Set PROTO = SEL for standard SEL ASCII protocol. For SEL Distributed Port
Switch Protocol (LMD), set PROTO = LMD. Refer to Appendix C for details on the LMD protocol. For
Distributed Network Protocol (DNP), set PROTO = DNP or DNPE. Refer to Appendix H for details on
DNP protocol.
The following settings are used if PROTO = LMD.
LMD Prefix (@, #, $, %, &)
PREFIX =
LMD Address (01–99)
ADDR =
LMD Settling Time (0–30 seconds)
SETTLE =
Communications Settings
Baud Rate (300, 1200, 2400, 4800, 9600, 19200) SPEED =
Data Bits (6, 7, 8)
BITS =
Parity (O, E, N) {Odd, Even, None}
PARITY =
Stop Bits (1, 2)
STOP =
Other Port Settings (See Below)
Time-out (0–30 minutes) T_OUT =
Send Auto Messages to Port (Y, N, DTA)
AUTO =
Fast Operate Enable (Y, N)
FASTO P =
Other Port Settings Set T_OUT to the number of minutes of serial port inactivity for an automatic log
out. Set T_OUT = 0 for no port time out.
Set AUTO = Y to allow automatic messages at the serial port. Set AUTO = DTA to use the serial port
with an SEL-DTA2 Display/Transducer Adapter.
Set FASTOP = Y to enable binary Fast Operate messages at the serial port. Set FASTOP = N to block
binary Fast Operate messages. Refer to Appendix D for the description of the SEL-351A-1 Relay Fast
Operate commands.
