SM06 Rev. 4.10 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.
2.3.4 Mechanical Mounting
Installation should be in accordance with the aircraft manufacturer’s instructions for
continued airworthiness or AC 43.13-1B Change 1, chapter 7, sections 2 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.

Notes
2.3.5.1 Control 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.
2.3.5.2 Additional 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
