Remote Control
The switcher can be remotely controlled via its rear panel
Remote connector (Figure 3-1). Remote control devices can be:
•
A host device such as a computer or control system
•
A device such as an Extron IR 102 Universal remote
control kit
•
A contact closure device such as an Extron KP 6 Keypad

Three remote control methods are available:
•
Extron's Simple Instruction Set
•
Extron's Windows-based control program
•
Contact closure
N
The cable used to connect the Remote port to a computer,
control system, contact closure device, or IR control kit
may need to be modified by removing pins or cutting
wires. If unneeded pins are connected, the switcher may
hang up.
For RS-232, Windows-based program, and IR control, use a
control cable with only pins 2, 3, and 5 connected. Otherwise,
either cut the wires to the other pins in hard-shelled connectors
or remove the unneeded pins from molded plugs. See "Simple
Instruction Set Control
definitions of the SIS commands. See "Windows
Program Control", beginning on page 3-15, for details on how to
install and use the control software.
For contact closure, use a control cable with pins 2 and 3
disconnected. Otherwise, either cut the wires to these pins in
hard-shelled connectors or remove these pins from molded
plugs. See "Contact Closure Control", beginning on page 3-18,
for information on how to make a remote contact closure device.

Simple Instruction Set
Host-to-interface communications
SIS commands consist of one or more characters per field. No
special characters are required to begin or end a command
character sequence. When a command is valid, the unit executes
the command and sends a response to the host device. All
responses from the unit 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.
Symbol definitions
Symbols (variables), defined on the next page, are used
throughout the "Unit-initiated messages" section and the
command/response table on page 3-6. The symbols represent
variables in the unit-initiated messages and the command/
response table fields.
