Connecting Clockaudio microphones and mounts to a Logic Box

Goal

After completing the steps in this article, you will be able to connect a Clockaudio microphone or mount to a Biamp Logic Box.  This will allow your Audia or Nexia configuration to control the LED's on the device, and it will also allow the microphone's switch to control functions within your Audia or Nexia configuration (like mic muting).  Some Clockaudio products have multi-color LED's (red/green), others have single-color LED's; some have mechanical mute switches, others have touch-sensitive switches.  Regardless of the model used, all Clockaudio products that have an RJ45 cable use the same wiring scheme, described below.

Note that the Logic Box cannot supply the DC power required to activate any LED's connected to it.  Therefore, an external power supply is required to power the LED's.  This power supply is not included with either the Clockaudio product or the Biamp Logic Box.

Conductor colors

Each Clockaudio device has a 5-conductor cable tail attached to it, which is terminated to an RJ45 connector.  When connecting the device to a Logic Box, the RJ45 connector is sometimes cut off.  The 5-conductor cable tail is comprised of the following colors:

Older models of many Clockaudio products had different color conductors than the ones listed above (and in some cases, they may have had different DC voltage requirements as well).  Check the included Clockaudio documentation to confirm the wiring scheme and voltage requirements.
