970 Series
Channel Change Encoder / Decoder

Remote Channel Reconfiguration



The 970CE uses standard 5 tone selcal to initiate a channel change, enabling any existing 5 tone system to be used to initiate a command on the 970CD.

Separate ports for audio and channel change information is provided to allow simple installation. Channel change information is provided from voltage free normally open or closed relay contacts via a "D15" socket. This provides flexibility in interfacing to base radio equipment. The relay outputs can be configured as 1 of 8 outputs or 2 x 4 BCD outputs, giving a range of 0-99 channels.


Omnitronics 970 Series Channel Encoder/Decoder


Channel change operation is simple and quick, using 2 or 3 button operations. An audible acknowledge tone is sent from the 970CD to inform all users that a channel change has taken place. Systems using 960HA & 960CA display handsets and consoles will have the new channel number displayed on the screen.

An extended mode of operation can be utilised to monitor and control other features of radio operation, such as mains standby power switching, RF power measurement, low battery monitoring etc. This mode allows up to 4 inputs and 4 outputs to be used.

The 960CD can also be used in conjunction with a 619E 6 way 4 wire audio bridge and associated 619BC Audio Bridge Controller(s) to remotely control multiple audio configurations. The audio source for the decoder can, in fact, be one of the six bridge channels configured as a control channel.
