The System 5 IP switcher can be remotely set up and controlled via a host
computer or other device (such as a control system) attached to the rear panel
Config/RS-232 port or LAN port, or the front panel Config port.
The System 5 IP must be configured before use. As shipped the switcher works
as a stand-alone A/V switcher but cannot control any other devices before being
configured.
The switcher can be set up and controlled by using Extron’s Simple Instruction Set
(SIS) commands or the Extron Global Configurator software (version 2.1 or higher)
for Windows, and both of those methods can be accessed via RS-232 or Ethernet
LAN connection. See chapter 2 for pin assignments and other details on the
configuration and control ports. For information on Global Configurator and the
switcher’s embedded Web pages, see chapter four.
Switcher’s RS-232 protocol:
• 38400 baud
• 8 data bits
• 1 stop bit
• no parity
• no flow control
Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The Global Configurator
software automatically sets the connection for the appropriate speed. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
LAN port defaults:
• switcher’s IP address: 192.168.254.254
• gateway’s IP address: 0.0.0.0
• subnet mask: 255.255.0.0
• DHCP: off
Host-to-switcher Communications
SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the switcher determines
that a command is valid, it executes the command and sends a response to the host
device. All responses from the switcher to the host end 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
If you communicate with the System 5 IP via RS-232 or via a verbose Telnet
connection, when a local event such as a front panel selection or adjustment takes
place, the System 5 IP responds by sending a message to the host. No response is
required from the host. The switcher-initiated messages are listed here
(underlined).

Vx.xx is the firmware version number.
The System 5 IP sends the boot and copyright messages under the following
circumstances:
• If the System 5 IP is off and an RS-232 connection is already set up (the PC is
cabled to the System 5 IP and a serial communication program such as
HyperTerminal is open), the connected unit sends these messages via RS-232
when it is first powered on.
