The digital output can be configured for a few different uses such as an indication of the reception of a
Fleetlink Message. It is a “Current Sinking” output. It typically drives two terminal peripheral devices
such as lamps, annunciators, and relays. One terminal of these devices is typically connected to a power
source of up to 50 Volts DC, and the other terminal is connected to the digital output of the Airtext Router
(pin 4).
A Sample wiring diagram showing typical Digital Input and Output connections is shown below.
ARINC Configuration
ARINC configuration specifies which ARINC labels are expected at which bus speed (High or Low), on
which port (1 or 2). Typically GAMA labels are predictable. Some FMS publish different data on
different labels.
Configurations can be created by Send Solutions Technical Staff to support most Flight Management
Systems. Some information about the hardware installation, FMS type, and customer preferences is
required. Airtext routers have two ARINC input ports. Each port can be independently set to LOW or
HIGH speed. Typically only ARINC Ground speed or the Weight on Wheels signal is needed to
automate the take-off and landing functionality. Optional customer preference information might include
Altitude, Headwind/tailwind, ETE, Date/Time, GPS Location, Distance to destination, Destination
Airport. Ground speed, Air speed, Mach, etc.
Send Solutions recommends that the connection to the airplanes FMS to be GAMA HIGH Speed Protocol
with physical connection of the FMS ARINC-429 wiring to the Airtext routers port 1.
