SEL Distributed Port Switch Protocol
Operation
Operation
1. The relay ignores all input from this port until it detects the
prefix character and the two-byte address.
NOTE: You can use the front-panel
{SET} pushbutton to change the port
settings to return to SEL protocol.
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 command terminates the connection. If no data are
sent to the relay before the port time-out period, it
automatically terminates the connection.
6. Enter the sequence <Ctrl+X> <QUIT> <Enter> before
entering the prefix character if all relays in the multidrop
network do not have the same prefix setting.
