Placement
The card reader (ETS-UP) device must be in an easy to reach location as the
driver needs to use it to unlock the truck before use.
For the best shock detection, we advise to place the IO expansion (ETS-DN)
firmly connected to the truck frame and perpendicular with the ground and
the moving direction.
Avoid installing the ETS in environmentally hard location such as close to
strong heat sources or exposed to the elements (although the ETS is IP65).
Also be aware not to place the card reader (ETS-UP) close to metallic objects
which can prevent the wireless transmissions.
