Extron electronics DTP CrossPoint 84 - Host-To-Switcher Instructions

DTP CrossPoint 84 Series Matrix Switchers • Programming Guide 53
NOTES:
• The factory configured passwords for all accounts on this device have been set
to the device serial number. Passwords are case sensitive. If the device is reset,
the password will be the original password configuration.
• 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 five minutes but the value can be changed (see the
Configure port timeout SIS command on page68).
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 DTP CrossPoint 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
device, the number of connections should stay low and unnecessary open sockets should
be closed.
Using Verbose Mode
Telnet connections to a DTP CrossPoint 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 command
on page68).
Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through the rear panel
Remote RS-232 port, the front panel Configuration port, and the rear panel Ethernet
(LAN) 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.
