Communications Settings: COMMINF is available on Port 4 only.
Set COMMINF = Modem is only available if supported by the part number.
Other Port Settings
Minutes to Port Time-out (0–30) T_OUT :=
Send Auto Messages to Port (Y, N)
AUTO :=
Enable Hardware Handshaking (Y, N, MBT)
RTSCTS :=
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 RTSCTS = Y to enable hardware handshaking. With RTSCTS = Y, the meter will not send characters
until the CTS input is asserted. Also, if the meter is unable to receive characters, it deasserts the RTS
line. Setting RTSCTS is not applicable to serial Port 1 (Ethernet), Port 4A (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 meter deasserts
the RTS line and does not monitor the CTS line. This selection is normally used with M
IRRORED BITS,
PROTO = MBA or MBB. See Appendix G: M
IRRORED BITS Communications 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 C: SEL Communications Processors for the description
of the SEL-734 Meter Fast Operate commands.
