Outputs 1 and 2 — For each output press the button for the desired input (1, 2 or 3). The LED for that input lights.

NOTE: When power is applied, the LEDs light sequentially from left to right. For first time power up, the default configuration is input 1 tied to both outputs

1 and 2, the front panel is not locked, and all states are unmuted. Input 1 LEDs for output 1 and for output 2 are both lit. If this is not a first time power up, then the LEDs for the last valid input selections light.

Front Panel Security Lock Out (Executive Mode)

Locking the front panel protects the switcher from unwanted tampering. While the switcher is locked, the user can select inputs only through a remote device.

To lock or unlock the front panel, press the following buttons simultaneously and hold them for at least 3 seconds:

•For output 1 press and hold input 1 button.

•For output 2 press and hold input 3 button.

The front panel LEDs flash to indicate the front panel is locked.

	OUTPUT 1			OUTPUT 2

Press and hold Input 1	Press and hold Input 3
Button for Output 1.	Button for Output 2.

System Reset

To reset the switcher to its factory settings, press and hold the input 3 button for output 1 while powering up the switcher.

Audio Switching

When you select an input, the audio and video signals from that input are routed together to the appropriate output.

Audio breakaway is possible through the Extron Simple Instruction Set (SIS) or the Extron Universal Switcher Control Program. When audio breakaway is active, the front panel input LED for the audio source flashes, while the LED of the video source lights steadily.

Device Control

Output Control

Momentarily short the rear panel Remote contact pin 1, 2, or 3 for the desired output to ground to switch to that input.

Use the +5 V port when controlling the output with an MMX 32 AAP or MMX 32 MAAP panel.

RS-232 Control

Software control via the RS-232 connection is possible using the Extron Simple Instruction Set (SIS) or the Extron Windows®-based control program. The RS-232 connector on the MMX 32 VGA MTP is a 3-pole captive screw connector.
