5.3 Establish pairing – Unite CDD-8/4 and Unite CDS-4/2
Transmitters and receivers must be paired so that they can communicate with each other. For a successful
pairing the channel name, group ID and audio encryption key are required. The required audio encryption
key is generated in the Unite CDD-8/4, CDS-4/2 Cockpit desktop charger or via the Unite Manager software
and during the pairing process it is first stored on the cockpit case and then it is transferred to the
transmitter and receiver in the charging compartments.
There are three different ways to pair the Unite transmitters with receivers:
1. Via an individual charger (refer to the following description or system manual online).
2. Using the Unite Manager Software on a PC (refer to the Unite Manager Software manual or system
manual online).
3. Via dynamic channel search (refer to system manual online, chapter "Special functions".
The group ID refers to devices that can be combined to a virtual group. For example, all devices of a
building, a travel group or a conference room.
Use with the group ID 150 - 256
By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio
encryption key, which cannot be changed, is used for the group ID range of 150 to 256.
The audio encryption key ensures additional security against unauthorised listening during the wireless
transmission. Due to the factory-set audio encryption key the devices within the group ID range of 150 to 256
can connect to each other without pairing via the charger. In this case receivers can connect to transmitters
via the dynamic channel search.
Example: Via the dynamic channel search, a receiver which is set to the group ID 160 will find all transmitters
which are active and also set to the group ID 160. The receiver can connect to a transmitter without pairing.
The receiver will not find transmitters beyond the set ID range of 160.
Attention: When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at
the same time, make sure that the individual channel names differ from each other! Otherwise this can
cause connection problems with the receivers!
