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. For M

The following settings are used if PROTO = LMD.
LMD Prefix (@, #, $, %, &) PREFIX =
LMD Address (01–99) ADDR =
LMD Settling Time (0–30 seconds) SETTLE =

Baud Rate (300, 1200, 2400, 4800, 9600, 19200, 38400)

Time-out (0–30 minutes) T_OUT =
Send Auto Messages to Port (Y, N, DTA) AUTO =
Enable Hardware Handshaking (Y, N, MBT) RTSCTS =
Fast Operate Enable (Y, N) FASTOP =
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 RTSCTS = Y to enable hardware handshaking. With RTSCTS = Y, the relay will not send
characters until the CTS input is asserted. Also, if the relay is unable to receive characters, it
deasserts the RTS line. Setting RTSCTS is not applicable to serial
PORT 1 (EIA-485) or a port
configured for SEL Distributed Port Switch Protocol (LMD).
Set RTSCTS = MBT is only available at 9600 baud (SPEED selection). In this mode, the relay
deasserts the RTS line and does not monitor the CTS line. This selection is normally used with
M
IRRORED
B
ITS
, PROTO = MBA or MBB. See Appendix I for more detail.
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-351 Relay Fast
Operate commands.
