Number of connections
A DXP 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 your switcher, keep the number of
connections low and close unnecessary open sockets.
Command and Response Table for SIS Commands
The switchers have SIS commands that you can use for operation and configuration. You can issue these commands from
a PC connected to the DXP serial port, USB port, or Ethernet port (see
information). The following symbols are used in the Command and Response Table for SIS Commands:
]
= Carriage return and line feed
• = Space
NOTES:
•
Commands can be entered back-to-back in a string, with no spaces. For example: 1*1!02*02&003*003%4*8$.
•
The matrix switchers support 1-, 2-, and 3-digit numeric entries (1*1!,02*02&, or 003*003%).
