Communications Arbitration Unit

Dispatch Communications
Telephone and Radio Headset Jack Box

The Communications Arbitration Unit (CAU) is a USB headset adapter which allows the use of professional air traffic control and/or dispatcher industry (PJ-7) headsets and handsets with any computer via the USB port. It features two twin jacks, which each support the WE-425, PJ7 or “310 connector”. It requires no external power and supports PTT devices like the Plantronics SHS1890.

Includes CauPTT,  a lightweight application that runs in the WINDOWS background.  It allows you to quickly map each PTT to a keyboard “hotkey” or mouse button.  This is useful for integrating with a third-party voice communications program (such as Motorola Dispatch).

Allows  dispatcher to:

• control both telephone and radio through a single headset.
• listen to both the telephone and radio at the same time.
• manually control whether the headset is on the telephone or radio
• rapidly switch back-and-forth, between telephone and radio
