ARINC 429 Interface (special order)
23. The ARINC 429 interface option enables the transmitting of aeronautical and pressure parameter
data to the aircraft system. It also monitors ARINC 429 data from the aircraft and shows the data on
the display with the corresponding measured parameter from the ADTS 405. The labels used for
transmitting and receiving each parameter conform to the standard ARINC 429 labels. The interface is
contained on an option PCB and locates and connects into the motherboard. An external connector
provides for one transmit and one receive channel. A connector fitted to the front panel provides
connection to the aircraft ARINC 429 data bus.
Altimeter Encoder Interface (special order)
24. The altimeter encoder interface receives the 10-bit digital code from the altimeter enabling the
ADTS 405 to display the decoded altitude value and the applied aeronautical value. A connector fitted
to the front panel provides connection to the altimeter encoding circuit.
IEEE 488 Interface (option E)
25. The IEEE 488 Interface option provides a parallel communications system compatible with either
1975 systems (option E-1) or SCPI protocol (option E-2). Amphenol connectors fitted to the front and
rear panels provide connection to a suitable computer.
