QM-MD8x8 Digital Input Signal Descriptions

INPUT DESCRIPTION

VideoEnter This input enables the video source select

analog for as long as the input remains high. For

most applications, this input should be set high,

which will allow all video sources to propagate to

the QM outputs immediately.

AudioEnter This input enables the audio source select

analog for as long as the input remains high. For

most applications, this input should be set high,

which will allow all audio sources to propagate to

the QM outputs immediately.

FrontPanelLockout

This input locks out the LOCAL button on the

front panel of the MD8x8 for as long as the input

remains high. When this input is high, the user

cannot switch the unit into local mode. However,

the user can use the front panel buttons to view

system connections. If the unit is already in local

mode, the activation of this signal will take the

unit back into system mode.

NOTE: When the front panel is locked, the MD8x8 will switch to the system mode

and use the switching schema specified by the control system.

QM-MD8x8 Analog Input Signal Descriptions

INPUT DESCRIPTION

VideoOut1 through VideoOut8 Select the QM video source to be switched to the

indicated QM output. Valid analog values range

from 0 (for no source) through 8, and correspond

to the QM 1 input through QM 8 input. Thus to

route a video source from QM In 5 to QM Out 7,

initialize VideoOut7 to 5d.

AudioOut1 through AudioOut8 Select the QM audio source to be switched to the

indicated QM output. Valid analog values range

from 0 (for no source) through 8, and correspond

to the QM 1 input through QM 8 input. Thus to

route an audio source from QM In 5 to QM Out 7,

initialize AudioOut7 to 5d.

NOTE: When programming the MD8x8 using digital and analog commands, serial

commands should not be used. Similarly, if the MD8x8 is to be programmed with

serial commands, digital and analog commands should not be used. However, analog

outputs can be monitored.
