Date Code 20060320 Instruction Manual SEL-311C Relay
SEL Distributed Port Switch Protocol (LMD)
Operation
Operation
1. The relay ignores all input from this port until it detects the
prefix character and the two-byte address.
2. Upon receipt of the prefix and address, the relay enables echo
and message transmission.
3. Wait until you receive a prompt before entering commands to
avoid losing echoed characters while the external transmitter is
warming up.
4. Until the relay connection terminates, you can use the standard
commands that are available when PROTO is set to SEL.
5. The QUIT (QUI) command terminates the connection. If no
data bits are sent to the relay before the port time-out period, it
automatically terminates the connection.
6. Enter the sequence <Ctrl+X> QUIT <CR> before entering the
prefix character if all relays in the multidrop network do not
have the same prefix setting.
NOTE: You can use the front-panel
{SET} pushbutton to change the port
settings to return to SEL protocol.
