Polycom MX392 Manual De Usuario

 

  

Let's say that you want MX392 to be unmuted by default.   If someone pushes the membrane 
switch, you want the microphone to stay muted until the user presses the switch to unmute the 
microphone.  You also want the LED to illuminate when the microphone is unmuted and not 
illuminate when the microphone is muted. 

  

First, set DIP Switch S1, S2, and S3 to ON and set S4 to OFF.  Then, connect SWTICH OUT to one of 
the Logic Input pins 1-24.  Connect LOGIC GND to Logic Output pins 21-25.  Connect LED IN to one 
of the Logic Output pins 1-20.

First, you want to make sure that the Vortex Device has all microphones unmuted as part of the 
Power on Preset.  Next, you need to make sure that if the unit is controlled by a control system that 
the proper commands are sent to the Vortex Device to unmute the microphones when the room is 
used for conferencing or sound reinforcement purposes.  Remember that since the requirement is 
push to mute, the user of the microphone is the one that must initiate the activity of muting the 
microphone.

Go to the Logic Input page of Conference Composer.  If the SWITCH OUT wire is connected to Logic 
Input pin 1, then you need to assign Pin 1 by left-clicking the desired pin in the DB-25 graphic and 
selecting the pink color (The pink color means that the pin is not grouped to other pins).
