IFD5XX Installation Manual
600-00299-000
Page 46 of 198
Revision: 02
The Approved Model List for the STC will indicate if an aircraft is required to install wire
harness overbraid on the IFD5XX wiring. Note: Overbraid is not required on VFR only
installations as defined in Section 2.4.1.
4.5.3 Copper Overbraid Installation
The copper overbraid must be a minimum 90% optical coverage per ASTM-B-33. The
overbraid must be grounded at both ends. If the aircraft wiring passes through wire
disconnects or bulkheads, the overbraid should be continued on each segment.
The wire harness overbraid should also be installed per FAA AC 43.13-1B Chapter 11-189.

4.7 Byteflight Digital Data Bus Consideration
– Dual IFD Installations
Dual IFD installations use a Byteflight digital Databus protocol when connected via RS-232
Channel 3 and configured for CrossSync. The following must be considered for replacement
and new installations.
4.7.1 Databus Wiring - Replacement Installations
For installations that are replacing two previously connected GNS4xx/5xx systems, the
Byteflight digital Databus is capable of using the pre-existing wiring between the two pre-
existing trays with no additional wiring or modifications required. All bus termination is
built into the IFD units. However, the existing wire length on the CrossSync connection must
not exceed 8 feet in length on IFD5XX RS-232 Channel 3 on P1001. Installations with longer
installation lengths between IFD5XX units must use Byteflight cable. The ByteFlight wire is
available from Avidyne, reference Table 15.
