Remote Operation
The MAV AV Series switchers can be remotely controlled via the switcher’s rear
panel RS-232 connector (figure 4-1) or using an optional infrared small matrix
universal remote control (figure 4-2).

The RS-232 protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.
RS-232 remote control devices can be either a host device, such as a computer or a
control system.

When using communications software such as HyperTerminal to control the
MAV switcher, verify that the terminal emulation is set to Auto Detect or
ANSI and set flow control to None. Other settings may cause errors.

Two remote control methods are available: Extron’s Simple Instruction Set and
Extron’s Windows-based control program.

Operation of the IR 501 remote control is described in the IR 501 Small Matrix IR
Remote Control User’s Guide.

The switcher’s IR receiver is disabled by default and must be enabled to use
the IR remote control. See the IR receiver enable SIS command on page 4-7 to
enable the IR receiver.

enable the IR receiver.
Using the hardwired IR input on pin 9, you can use a control system with
IR-learning capabilities to operate the switcher just as if you were using an IR 501
remote control. The control system must first “learn” the IR command from an
IR 501, after which, it sends the same commands to the MAV via pin 9.

Simple Instruction Set Control
Host-to-Switcher instructions
The switcher accepts SIS (Simple Instruction Set) commands through the
RS-232 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 =

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.
