Administrator .

Number of Connections
An HDXP switcher can have up to 200 simultaneous TCP connections, including all http
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, keep the number
of connections low and close unnecessary sockets.
Verbose Mode
The connection to an HDXP switcher can be used to monitor for changes that occur on
the switcher, such as front panel operations and SIS commands from other connections
or a serial port. To receive change notices from the switcher, you must enable verbose
mode 1 or 3 (see
Verbose Mode Commands on page 66). In verbose mode 1 or 3,
changes are reported in messages that resemble SIS command responses.
Host-to-Switcher Instructions
The HDXP accepts SIS (Simple Instruction Set) commands through the
RS-232/RS-422 and Ethernet ports. 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.
Switcher-Initiated Messages
When a local event such as a front panel operation occurs, the switcher responds
by sending a message to the host. The switcher-initiated messages are listed below
(underlined).
With an RS-232 or RS-422 connection:
(c) Copyright 20nn, Extron Electronics HDXP Plus Series, Vn.nn, 60-nnn-01 ]
With an Internet connection:
(c) Copyright 20nn, Extron Electronics HDXP Plus Series, Vn.nn , 60-nnn-01 ]
Ddd, DD Mmm YYYY HH:MM:SS ]
The switcher initiates the copyright message when it is first powered on or when
connection via Internet protocol (IP) is established.
Vn.nn is the firmware version number,
60 - nnn - 01 is the HDXP model part number, and 20nn is the copyright year.
] 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.
NOTE: The Password prompt dialog box is redisplayed if an incorrect password is
entered.
