NOTE:
The connector pin numbers given in the Table above are to the best knowledge of Honeywell EGPWS engineering. Please
contact the manufacturer’s customer service to confirm your installation.
NOTE 1: The following RT-300 part numbers meet ARINC 552 for the Auxiliary Output: 7001840 -902, -906, -912, -
916, -917, -918, -922, -926, -928, -932, -936, -937, and -938. RT-221’s are also compatible, consult your
Honeywell representative.
NOTE 2: This is the Precision Output from the R/T. Note the + and – signals are swapped to convert the –
4mV to +4mV. RT-300 (-901, -903, -905) should use the Precision Output, same as RT-220.
3.10.5 Digital – AR INC 429 Dual IOC Buses (Cat. 8 ID 251- 255)
Radio Altitude Type 251 (IOC bus or equivalent) is a dual high speed, digital ARINC 429 signal having labels
164 and 170. Radio Altitude Type 252 (IOC bus or equivalent) is a dual high speed, digital ARINC 429 signal
having labels 164 and 370. Radio Altitude Type 253 (IOC bus or equivalent) is a dual high speed, digital ARINC
429 signal having label 164 and a analog discrete DH input. Radio Altitude Type 254 (IOC bus or equivalent) is
a dual high speed, digital ARINC 429 signal having labels 164, 170 and 370. Radio Altitude Type 255 (IOC bus
or equivalent) is a dual high speed, digital ARINC 429 signal having labels 164 and 370. For interface
description see paragraph 3.4.5 Air Data Type 255.
