Using the MLC 52 Configuration Program | Extron electronic specification

Serial Communication

The MLC 52 can be remotely configured via a host computer connected to the front panel configuration port. Through this port, you can program the MLC’s buttons with commands by using the Windows®-based configuration software (MLC 52/DVCM 50 Configuration Program). You can also issue certain SIS™ (Simple Instruction Set) commands through this port. The optional 9-pin D to

2.5mm stereo mini TRS RS-232 configuration cable (part #70-335-01) can be used for this connection.

The connector has the following pin assignments:

1 6

Pin 2	Computer's RX line	Tip
Pin 3	Computer's TX line	Ring
Pin 5	Computer's signal ground	Sleeve

Using the MLC 52 Configuration Program

To perform advanced configuration tasks (e.g., setting button modes, updating firmware, adding display device drivers), you must use the included Extron Windows-based configuration software. Many items in the MLC 52 Configuration program are also accessible via front panel controls described in chapter 3, “Operation.” Refer to that chapter for details on features and settings. Some features are available only via this configuration program. The MediaLink Help Program provides information on settings and on how to use the configuration program itself.

To install and run the MLC 52 configuration software, ensure that your PC meets the following system requirements:

•Microsoft® Windows 2000 or later

•Pentium III or better processor (or compatible)

•32 MB free hard disk space

•Microsoft® Internet Explorer© 4.0 or above

•4x or higher CD-ROM player

•Minimum 1024 x 768 screen resolution

Extron’s Windows-based configuration software is provided on a CD, which is packaged with the MLC. The program can also be downloaded from the Extron Web site (http://www.extron.com). Install this software on your computer.
