Tac/Com Control Head Manual

1.3Purpose of Equipment

The Tac/Com series of control heads provides a centralized location for tactical radio control and channelling of up to four independent transceiver systems. Only the Tac/Com II series will be considered; for further information, contact NAT Ltd.

Alphanumeric labeling of each radio channel is provided, as well as a display of receive and transmit frequencies, to ease pilot identification of the selected channel on each radio.

At the Tac/Com (master) control head, individual radio receive volume and radio power on/off status can be controlled. Individual radio functions can also be set, such as scanning, tones, simplex/duplex, TX power and others. Annunciation is provided for TX and RX activity on a per transceiver basis, and the main display can be set to show the channel name (alphabetic label), the receive frequency and tone data, or the transmit frequency and tone data for all radios via the general control group.

(2 Radios, 256 Total Channels)

Within the control head, individual radio interface cards translate the control head commands into suitable channelling data for each specific type of radio connected. Software controlling these functions, as well as the built-in help screens for control head operation, is located on the main control head CPU board and can be easily replaced to upgrade or improve control head functions.

The software of the control head's computer can emulate many types of parallel tuned radio controls and this allows the Tac/Com system to directly replace many existing controls such as the C-960, C-961, C-962A, C-722A and C-1000. In addition, since the Tac/Com control allows control of up to four simultaneous radio systems, the single Tac/Com control can replace up to four individual controls, with a substantial reduction in cost and panel space. The following diagram illustrates a system that shows this multiple radio capability using NAT NT-series agile transceivers. Any combination of radios could be used by installation of the appropriate interface cards within the control head. In the example below, an accessory DTE12 is used for DTMF tone generation and direct keyboard data input to the TH450.
