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 the performance of your switcher, keep the
number of connections low and close unnecessary open sockets.
Establishing a USB Port Connection
A standard USB cable and the Extron DataViewer utility, version 2.0 or
newer, can be used for connection to the DTP CrossPoint matrix switcher
Configuration port. The USB cable, available at any local electronics store,
should be terminated on one end with a mini USB B male connector.
Host-to-Switcher Instructions
The switcher accepts SIS commands through its serial port, its USB port,
or its 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 =
signals the end of the response character string. A string is one or more
characters.
