NOTES:
1. Two wire shielded cable. Tie shields to aircraft dc ground.
2. Tie chassis ground to aircraft frame.
3. Two wire shielded cable. Tie shield to pin 5.
4. Two wire shielded cable. Tie shield to pin 16.
5. The 115 V ac (H) and 115 V ac (C) should be shielded or twisted and shielded with an insulating
jacket over the shield. The shield should be connected to chassis ground (pin 21).
6. There is a +28 V dc output available from the transponder, however most ARINC 615 Data
Loaders do not have the capability to operate from 28 Volt power.
7. If the RS−232 interface is going to be used, these pins should be connected to a standard serial
port (usually a 9−pin D connector).
