2、ASM-822 intelligent mixer can contact VTS-1000 Video track system by RS-200 port to open the video conference.

RS-232 port pin indication

1:NC

2:TX(data output)

3:RX(data input )

4:NC

5:GND(grounding)

remark: only the host can

use video track function.

6:NC
7:NC

8:NC

9:NC

3、ASM-822 intelligent mixer can outer intelligent control by contacting the inter control
system by logical port:

1：CH8 OUT 2：CH7 OUT 3：CH6 OUT 4:CH5 OUT 5:CH4 OUT 6:CH3 OUT

7：CH2 OUT 8：CH1 OUT 9：GND 10：GND 11：GND 12:GND

13：GND 14:CH8 IN 15：CH7 IN 16：CH6 IN 17:CH5 IN 18:CH4 IN

19:CH3 IN 20:CH2 IN 21:CH1 IN 22:GND 23:GND 24:GND 25:GND

Logical control mostly used on control outer input and outer output

Control input :when external control input high level to a channel ,the channel gate will be compulsory

open; when external control input low level to a channel ,the channel gate will be automatic test, the gate
will be open only AF signal through it.
Control out: when microphone is open, the gate of this channel will output high level .
When the microphone is mute, the gate of this channel will output low level

Rotate the encoder switch can adjust the volume of AF input, push the encoder switch, then yellow LED will twinkle，it
indicate enter menu select mode，then rotate the encoder switch can choose corresponding function. For example,
the “on” yellow light is twinkle ,it indicate select “on” function, then push the encoder switch again, and will start

use “on” function. If the “on” red light is on, it indicate start use prior speak mode, if the “on” light is off, it

indicate start use automatic test mode.

ASM-822 intelligent mixer use encoder switch ，every encoder switch can operate corresponding function.
For example of CH1,the specific operation as the bellows:
