Page 6: Potentially Explosive Environments
• Do not store the TW1m modem in hot areas. High temperatures can shorten the life of electronic devices, damage batteries and warp or melt certain plastics. • Do not store the TW1m modem in cold areas. When it warms up (to its normal temperature), moisture can form inside, which may damage electronic circuit boards. -
Page 7: Device Overview
• Programming interface The TW1m modem is designed to be a TETRA modem solution that is compact in size yet provides a full TETRA feature set required by typical data and voice applications. It has been made integrator- and service friendly with commercial off-the-shelf connectors and a standard programming interface. - Page 8 MAB-1 must be integrated into an enclosure for environmental protection. Interfaces are provided as commercial connectors and external cabling must be customized by the user.

Page 9: Technical Data
The integrating requires that the cables are tailored to the optimum length. Airbus does not provide the tailored cables. The RF antennas should be installed a minimum of 50cm from the TW1m boards to avoid TETRA interferences. Note: Simultaneous use of AT commands and IP data is not supported. -
Page 10: Device Layout
The TW1m modem features a GPS receiver for positioning applications. An external active GPS antenna is required for the receiver. Do not use a passive GPS antenna! The TW1m modem does not have an integrated TETRA antenna. Therefore, a connector for an external antenna is provided. A combined TETRA/GPS antenna can also be used. - Page 11 Data mode FBUS parametering MBUS prametering Table 3 Operation mode truth table (X = Any value) TW1m - Instruction Manual PS11730AENAD01 11/27 This document is the property of Airbus DS SLC and should not be copied or circulated without permission.
