Extron electronic MVX 84 Remote Operation, IR Remote Control, Matrix Switchers Control Program

Remote Operation

This section describes the operation of the MVX VGA Matrix Switcher, including:

•IR Remote Control

•Simple Instruction Set Control

•Matrix Switchers Control Program

SIS commands and the Matrix Switchers Control Program require a connection to the rear panel RS-232 port by either a host device, such as a computer, or a control system (see item d and “Remote Connection” on page 6). The serial port protocol is:

•9600 baud

•8-bit

•1 stop bit

•No parity

•No flow control

NOTE: When using communications software such as HyperTerminal to control the MVX switcher, verify that the terminal emulation is set to Auto Detect or ANSI

and set flow control to None. Other settings may cause errors.

IR Remote Control

Besides the RS-232 port, the MVX VGA Series switchers can be remotely controlled using an optional infrared Small Matrix Universal Remote Control (figure 21). Operation of the IR 501 remote control is described in the IR 501 Small Matrix IR Remote Control User Guide. Using the hardwired IR input on pin 9 of the RS-232 port, 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 MVX via pin 9.
