Connection timeouts
The Ethernet link times out after a designated period of time of no communications. By
default, this timeout value is set to five minutes but the value can be changed. See the
NOTE: Extron recommends leaving the default timeout at 5 minutes and periodically
issuing the Query (
Q
) command to keep the connection active. If there are long idle
periods, Extron recommends disconnecting the socket and reopening the connection
when another command must be sent.
Number of connections
A FOX matrix 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 an IP Link device,
keep the number of connections low and close unnecessary open sockets.
Using Verbose Mode
Telnet connections to a FOX matrix 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
Host-to-Switcher Instructions
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
unit executes it and sends a response to the host device. All responses from the unit to the
host end 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.
Switcher-initiated Messages
When a local event, such as an equipment power-up, occurs, the unit responds by sending
a message to the host. The unit-initiated messages are listed below:
(c) Copyright 20yy, Extron Electronics, FOX Matrix 320x,
Vx.xx, 60-1082-01]]
- or -
(c) Copyright 20yy, Extron Electronics, FOX Matrix 14400,
Vx.xx, 60-1255-01]]
The switcher issues the appropriate copyright message (above) when it first powers on.
Vx.xx is the firmware version number; 60-xxxx-xx is the part number of the connected unit.
]Password:
The switcher initiates the password message immediately after the copyright message when
the controlling system is connected using TCP/IP or telnet and the switcher is password
protected. This message means that the switcher requires an administrator or user level
password before it will perform the commands entered via this link. The switcher repeats
the password message response for every entry other than a valid password until a valid
password is entered.
