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. This is

specifically targeted at those outputs supporting auto pilot functionality, ensuring that those outputs

reset when the microprocessor resets.

Each discrete input provides 1mA of wetting current when connected to ground.

Both the Audio and Main board are capable of reading the state of 10 of the discrete inputs, and these

pins should be reserved as practical. This provides a low latency input path to the audio panel to allow

for current and future functionality where delay is undesirable. These functions include 3D Audio,

oxygen mask selection, key'ed ICS, and additional ASR Push-to-Command inputs.

5.1.2 Configurable ARINC-717/708 Interface

The GIA 6300 can support any combination of 2 ARINC-717 transceivers and 2 ARINC-708 receivers. The

GIA 6300 has an ARINC-708 receiver to support interfacing to a 3rd party radar. The GIA 6300 also

supports an ARINC-717 transceiver to add support for connecting to a 3rd party Flight Data Recorder.

These interfaces are combined such that they can be configured between ARINC-717 and ARINC-708.

The GIA 6300 has a total of 4 Ethernet interfaces. The 4 Ethernet interfaces are divided equally between

the two processors on the main boards, each interface can be used to support redundant connections to

the rest of the system from each processor. Each processor can have two high speed communication

paths independent of the 2nd processor.

These Ethernet interfaces are all capable of up to 100 Mbps of bandwidth, but it is not available in flight.

5.1.4 RS-485/422

The GIA 6300 has a total of 14 RS-485 transceivers. Any two of these transceivers can be paired

together to make one RS-422 interface allowing up to 7 RS-422 interfaces. The RS-485/422 interfaces

are capable of a maximum baud rate of 921.6 kbps.
