PHYSICAL CONNECTIONS AND GROUNDING

In order to connect the microphone to the Vortex Device, first connect the audio portion of the microphone to the Vortex Device: Connect the Positive conductor (Red) to the Positive terminal, the Negative conductor (Black) to the Negative terminal, and the Ground wire (gray) to the Ground terminal. Next, connect the SWITCH OUT (white) conductor to one of the Logic Input pins 1-24 and then connect the LED IN (orange) conductor to one of the Logic Output pins 1-20 (Note that the Logic Input and Outputs pins are fully programmable). Next, connect the LOGIC GND wire (green) to the audio ground wire. Although, you can connect the LOGIC GND wire to one of the ground pins on either the Logic Input or Logic Output port, both the Logic port ground pins and the audio ground pin are tied to chassis ground of the unit.

The drawing below shows how to perform the wiring. Note that for clarification purposes the LOGIC GND wire is shown tied to the audio signal ground near the unit; however, this connection may be made at the microphone itself so that you will only need a 4 conductor cable plus ground wire to connect the microphone to the Vortex Device.

To accomplish this, we will use the BROADA command to send MUTEI commands from one unit to the other unit. The BROADA command broadcasts any command that is after the colon. For example, if a Macro in the Vortex EF2241 has this command Page LOGIC INPUT Page Page LOGIC OUTPUT Make sure the LED works as designed. If you press the membrane switch, you should see the LED above the pins illuminate in Conference Composer as well as on every MX392. Since the switch is a membrane switch, the LED will stay lit until the switch is pushed and held down Polycom Installed Voice Business Group Contact Information TECHNICAL SUPPORT
