An alternative STC approved mounting option is via hook and loop (Velcro) fastener. Airtext mounting
via two 3” strips of 1” Velcro exceeded a 9G pull test for securing the device. Velcro used was Part #
PBEGE1.00H (hook) and Part # PBGE1.00L (loop) manufactured by Skandia Inc. www.skandiainc.com
ROUTER CONFIGURATION
The personality of the Airtext router can be tailored for use in several kinds of environments. Each unit
is shipped with a standard configuration suitable for type 25 aircraft using ARINC-429 data that is
connected to the Airtext router’s channel 1 input using GAMA protocol at HIGH speed. This works for
most aircraft even if ARINC-429 wiring is not connected to the Airtext router. Send Solutions technical
staff can tailor a configuration specific to your use case. It is applied to the Airtext router using a phone or
tablet in a few seconds in the same manner that the router is updated with new revisions of firmware.
ARINC data or Weight on Wheels status is useful to the Airtext router as it can automate some take-off
and landing functions for a more pleasant and intuitive experience for both flying and ground-based users.
List of configurable items
System Firmware Configuration.
A portion of the configuration file is used for internal housekeeping and verification. Do not make
changes to the configuration without knowing what effect each change will have on the system operation.
Landing delay: optional time delay can be inserted between the physical landing of the airplane and the
triggering of the automated landing functions.
Iridium mailbox inquiry time. Settings are available for Airplane and Fixed location use.
Ground speed threshold: The ground speed that determines Flying and Landed.
Digital IO configuration
Three digital inputs exist on the Airtext router. Currently the router can be configured to monitor signals
such as the state of the optional Iridium antenna sharing relay and the state of the aircrafts Weight on
Wheels. The digital inputs support signals from 0 to 50 Volts. Voltages below 2 Volts are interpreted as
OFF and voltages above 9 Volts are interpreted as ON. Voltages between 2 Volts and 9 Volts are
indeterminate.
Weight on Wheels: Which input (1, 2, or 3) and does it have 28V when landed or when flying.
Antenna Sharing: Which input (1, 2, or 3) and does it have 28V when available or not available.
Mailbox check rate: Which input (1, 2, or 3) and the delay values for the active and inactive states.
Fleetlink Message Ack. Which input (1, 2, or 3).
