5.4 Mounting Guidelines
 Make sure that you use the total number of two screws to attach the TC1 to your vehicle.
 Tighten each screw with a preload force of F = 6.7 kN – 9.0 kN. Use the stated preload force to determine
the torque:
The torque of a screw depends of its type, its structure robustness, and coefficient of friction (COF). To
determine the torque of a screw, use the stated preload force and the data of your used screw.

 Make sure that you operate the TC1 always within the electrical and mechanical specifications defined by
STW. If you are not sure about your application, do not hesitate to contact STW's design team.
 Make sure to keep a minimum distance of 20 cm between the used antenna and people.
NOTE:
Cross the Rx/Tx pairs (6 <-> 2 and 3 <-> 1) for a 1:1 ethernet connection.
NOTE:
RS232 needs a common ground for communication (PC-GND <-> TC3-GND).
