Extron Electronics MTPX Plus 6400 Series User Guide - Manual (Page 73)

Establishing a Connection
Establish a network connection to an MTPX Plus matrix switcher as follows:
1. Open a TCP socket using the IP address of the switcher.
NOTE: If the local system administrators have not changed the value, the factory-
specified default, 192.168.254.254, is the correct value for this field.
The switcher responds with a copyright message including the date, the name of the
product, firmware version, part number, and the current date/time.
NOTE: If the switcher is not password-protected, the device is ready to accept SIS
commands immediately after it sends the copyright message.
If the switcher is password-protected, a Password prompt appears below
the copyright message.
2. If the switcher is password protected, enter the appropriate administrator or user
password.
If the password is accepted, the switcher responds with Login User or Login
Administrator.
If the password is not accepted, the Password prompt reappears.
Connection Timeouts
The Ethernet link times out after a designated period of time of no communications. By
default, this timeout value is set to 5 minutes but the value can be changed.
See the “
Configure port timeout ” SIS commands on page 85.
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 MTPX Plus 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, the number of connections should be kept low
and unnecessary open sockets should be closed.
Using Verbose Mode
Telnet connections to an MTPX Plus 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 “
Set verbose mode ” SIS command
on page 85).
