Installation Overview 3.1 Cabling and Wiring Coaxial cable with 50 Ω nominal impedance and meeting applicable aviation regulations should be used for the installation. A typical maximum cable length for the GPS antenna is 40 feet. The installer shall insure that the attenuation of the GPS cable run falls between 3 dB and 7 dB inclusive at 1.5 GHz. 3.2 VHF COM Cable Routing Avoid routing the COM antenna cable near aircraft control cables or near GPS antenna cables. Avoid sharp bends in the antenna cable.

5 GIA6300 Interfaces 5.1 I/O Data Concentration and Computation (provided by Main Boards) Table XXX lists the interfaces provided by Main A and Main B in the GIA 6300. Main A and Main B in the GIA6300 function as two independent units, and interfaces to specific units should not be split across the boards if practical.
PAGE 5
Each discrete output is capable of sourcing 20 mA in the active state when configured as active high. Six discrete outputs (3 per main board) can be used as super flag outputs capable of providing up to 0.5 Amps of current. Active low states are capable of sinking up to 0.5 Amps. All of the discrete outputs have a default state of inactive implemented during and after a reset.
PAGE 6
5.2.1 Key Event Out The Key Event Out active low discrete output signals that the GIA COM is transmitting. In installations with more than 2 VHF COM radios, this input can be used to connect to the Transmit Interlock input on the other radios. 5.2.2 RX Squelch Break The RX Squelch Break active low discrete output/input signals that the RF squelch has broken on the COM receiver.
PAGE 7
Speaker Outputs 2 5.4.1 Transceiver Interfaces The GIA 6300 supports a total of 8 radio transceivers including the internal VHF COM radio. One of these interfaces is used to connect to the cross-side GIA 6300 VHF COM. Four transceiver inputs can be configured as microphone inputs. This allows a total of 8 passenger or support staff positions per GIA 6300.

Figure XXX illustrates the AES3 interconnect configurations provisioned by the GIA 6300 AES3 interfaces. The majority of GIA 6300 installations will require only the low fidelity connection depicted by (A) with cross-side music audio being implemented with wiring splices.

5.4.6 Summed Audio Output The GIA 6300 has a summed audio output suitable for driving a CVR input. When in hardware failsafe, the COM is hardwired to the Summed output. 5.4.7 Speaker Output The GIA 6300 has two speaker outputs to support mid-sized aircraft that need one or two additional PA speakers in the cabin area but do not need the flexibility or output capabilities of a full IFE or passenger address system.

Note 2: See the Environmental Qualification Form for details on surge rating and minimum/maximum operating voltages. 7 Environmental Qualifications Reference the Environmental Qualification Form in Requiem GIA6300 EQF. 8 System Interconnect 8.1 Unit Level Connections Figure XXX shows the electrical top level design of the GIA 6300. The GIA 6300 consists of 9 separate circuit boards and the GPS module.
PAGE 11
8.2 System Level Connection Figure XX shows the system level, Ethernet interconnects between the GIA 6300 and the rest of the Garmin system. This shows a larger system containing 4 GSD data concentrators, GTC touch screen controllers, and GDU displays. Most foreseeable systems are expected to be a subset. The GIA 6300 implements 4 Ethernet interfaces between the two Main boards. Main A and Main B have independent processors each with a separate HSDB address.

This document also lists the keying for each connector. prism://hw-bin-vc.aviation.garmin.com/gia6300/trunk/Design/IO Board/GIA 6300 Pin Out.docx 10 Electrical Bonding Electrical equipment, supporting brackets, and racks should be electrically bonded to the aircraft’s main structure. Refer to SAE ARP 1870 section 5 when aluminum surface preparation is required to achieve electrical bond.
PAGE 13
Simultaneous COM performance varies significantly across installations and is affected by both the isolation between the COM antennas and the separation of the tuned frequencies. Each installation should be individually examined to determine the expected performance of simultaneous COM. 12 License Requirements The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion to eliminate radio station license requirements for aircraft and ships.

NOTES 1) The VHF transmitter in this equipment is guaranteed to meet federal communications commission acceptance over the operating temperature range. Modifications not expressly approved by Garmin could invalidate the license and make it unlawful to operate the equipment. 2) This device complies with Industry Canada’s license-exempt RSSs.
