NOTES:
1. Use AWG−24 single conductor, shielded wire. Attach shield to ground loop E1 or E2 on back of
mounding tray.
2. Two wire shielded cable. Tie shields to ground loop E1 or E2 located on back of mounting tray.
3. This ARINC 429 output is required on some Collins Control Panels that require a feedback loop to
make sure the transponder is working properly.
4. Refer to interface descriptions in Table 4−9.
5. This output is connected only if the control panel has an ALT FAIL input function.
