Connection Timeouts

The Ethernet link times out and disconnects after a designated
period of no communications. By default, this timeout value is set
to 5 minutes but the value can be changed.
NOTE:
5 minutes and periodically issuing the Query (Q) command to
keep the connection active or disconnecting the socket and
reopening the connection when necessary.

Number of Connections

A switcher can have up to 200 simultaneous TCP connections,
including all HTTP sockets and Telnet connections. When
the connection limit is reached, the switcher accepts no new
connections until some have been closed. No error message or
indication is given that the connection limit has been reached.
To maximize performance of your switcher, keep the number of
connections low and close unnecessary open sockets.

Verbose Mode

Telnet connections to a switcher can be used to monitor for
changes that occur on the switcher, such as front panel operations
and SIS commands from other Telnet sockets or a serial port.
For a Telnet session to receive change notices from the switcher,
the Telnet session must be in verbose mode 1 or 3 (see the
verbose mode

SIS Commands

The switchers have SIS commands that you can use for operation
and configuration. You can issue these commands from a PC
connected to the DXP serial port, USB port, or Ethernet port
(see Rear Panels and Connections
information).

Host-to-switcher Instructions

The switcher accepts SIS commands through the LAN port, the
Remote (RS-232) port, or the front panel USB Config port. SIS
commands consist of one or more characters per command field.
They do not require any special characters to begin or end the
command character sequence. Each switcher response to an SIS
command ends with a carriage return and a line feed (CR/LF =
which signals the end of the response character string. A string is
one or more characters.
