Tac/Com Control Head Manual

2.The interface cards for the RT9600 and RT7200 have different locks from those on the original harness. The tight packaging on the Tac/Com control head does not allow spring locks to be used. The harness locks must be changed to jackscrews to match the Tac/Com connectors before flight. New locking hardware is furnished with the control head when these cards are installed.

2.3.4Mechanical Mounting

Installation should be in accordance with AC 43.13-1B chapter 7, sections 3 to 7 and AC 43.13-2A chapter 2.

Mounting is accomplished in a standard Dzus rack or rail assembly with a clearance opening of 5", and full width dimension of 5.75". The rail height required for mounting the various control heads is shown below.

Tac/Com Series

Rail Height Required

250/260 and 350/360

3.00"

450A

3.75"

450B and 460B

3.375"

450/460

4.875"

Be sure that adequate rear cable clearance is allowed when planning console installations. Refer to the aircraft structural repair manual and maintenance manual for instructions and information pertinent to this installation.

2.3.5Notes

2.3.5.1Control Head System Connector

The J100 System Connector Power/Lights/Ground connections must be provided for operation of the overall system, in addition to the basic interface card-to-radio connections. For specific RT9600/7200 radios, see the relevant Interface Card supplement (SM06\PQRU\810-0) for an alternative method for providing these connections to the control head.

Pins 7, 10 and 22 are serial data control lines that may be brought out to a connector for serial loading of the control by a PC. This allows easy large scale data changes without removing the control head from the aircraft. NAT provides a special software package for this function. This port may also be used for Master/Slave operation or the DTE12 DTMF/Keyboard Data Unit.

2.3.5.2Additional Mounting Considerations

LED display units come in several different display filter styles (see Section 1.6), and the panel location and filter type should be matched for the best performance. LED displays offer very wide viewing angles, and are suitable for centre console mounting and locations not in the pilot's direct field of vision.
