FDL-DB DUAL BAND SERIES PORT CONFIGURATION
5.1
General
This section contains installation configuration and descriptions for serial and ARINC data
interfaces on the FDL-DB Dual Band Series.
5.1.1 FDL-DB Dual Band Series Serial, ARINC and Network Port
Configuration Details
The FDL-DB Dual Band Series installations require data interfaces to other equipment for
complete aircraft installation. The available data interfaces are Control Input (Transceiver Only),
GPS Input, Altitude Input, TCAS Input, Display Output, GPS Output, and GPS Predictive RAIM
Input. The FDL-DB Dual Band Series Serial, ARINC and Network ports must be configured to
enable these data interfaces and are described in the table below:
Table 2. FDL-DB Dual Band Series Installation Data Interfaces
Interface
Description
Control Input
Control inputs such as Flight Plan ID (Squawk Code), call sign, and mode
control (IDENT, Altitude Inhibit, transmit Standby) are needed by the FDL-
DB-XVR. The TC978 provides control or the FDL-DB-XVR can be configured
for other control formats. If a control format is configured and functional with
the TC978 installed, the TC978 displays control status but will not accept
control inputs. Serial port 2 is typically used for control input. Remote
network server ports 1 and 2 can also be used for control input.
Control Input is NOT required for receive only systems.
GPS Input
The FDL-DB Dual Band Series requires position, velocity, time, and integrity
data from a GPS sensor. The internal GPS or an external GPS must be
configured to provide this data.
GPS Input is required for all FDL-DB
systems.
Altitude Input
The FDL-DB Dual Band Series requires external pressure altitude data input
from an altitude/air data sensor (ADS). Altitude rate and airspeed will be
used if available in the configured protocol. Pressure altitude data output can
also be configured to share with a transponder. Serial port 4 is typically used
for Altitude Input.
Pressure Altitude Input is required for all FDL-DB systems.
Heading Input
The FDL-DB Dual Band Series can optionally receive aircraft true heading
data. True heading is sent in UAT transmit messages on the ground and is
also used to more accurately correlate TCAS and ADS-B Traffic. Heading
input is not required but desirable with TCAS installations.
TCAS Input
*Optional Feature
TCAS traffic MUST be input to the FDL-DB Dual Band Series if the aircraft is
TCAS equipped so the TCAS traffic can be integrated with ADS-B traffic and
a single traffic picture can be presented to the Display Output. The FDL-DB
Dual Band Series accepts TCAS traffic input via ARINC input per the ARINC
735A/B Intruder Labels.
