Subtask 34-52-00-860-093-A ** ON A/C NOT FOR ALL
A. Change of ICAO Address
(1) Change the ICAO address to binary format
(a) Find the correct plug AWM 345205 and AWM 345206.
(b) Do the pin-programming in relation to the binary format of the ICAO address.
For a pin to be at "1" on the plug, you must connect this pin to common pin b of the same plug.
Subtask 34-52-00-860-093-D ** ON A/C NOT FOR ALL (1) Change the ICAO address to binary format
(a) Find the correct plug AWM 345205 and AWM 345206.
(b) Do the pin-programming in relation to the binary format of the ICAO address.
For a pin to be at "1" on the plug, you must connect this pin to common pin b of the same plug.
NOTE: Pin A of the plug is Most Significant Bit (MSB).
NOTE: For example, for ICAO address C0099D (hexadecimal)/60004635 (octal):
- you change it to binary format: 1100 0000 0000 1001 1001 1101.
- you connect pins A, B, N, S, T, W, X, Y and a of the plug to pin b AWM 345205 and AWM 345206.
A. Change of ICAO Address
(1) Change the ICAO address to binary format
(a) Find the correct plug AWM 345205 and AWM 345211.
(b) Do the pin-programming in relation to the binary format of the ICAO address.
For a pin to be at "1" on the plug, you must connect this pin to common pin b of the same plug.
Subtask 34-52-00-865-069-A (1) Change the ICAO address to binary format
