Setting up
4.1
EVK-M8U installation
The EVK-M8U ships with an active GPS / GLONASS / BeiDou magnetic mount antenna with 3 m cable.
The following sections describe the steps required to complete the EVK-M8U hardware installation.
4.1.1
Mounting the GNSS antenna
Attach the antenna to the car; for best performance attach it on the roof as shown in Figure 33. Bring the
antenna cable in through the window or door. Be careful not to damage the antenna cable.
4.1.2
Mounting the EVK-M8U
The EVK-M8U should be firmly attached to the car body so as to avoid any movement or vibration with respect
to the car body. The EVK should not be attached to any ‘live’ (unsprung) part of the vehicle’s suspension. Often
it is enough to use strong double sided tape or Velcro tape glued to the bottom of the EVK-M8U casing. If
necessary, mounting brackets may be attached using the end-plate retaining bolts (M3). The EVK must be
secured against any change in position and particularly orientation with respect to the vehicle frame.
The EVK case-work, antenna and USB connectors are linked internally to the common
supply/interface ground (pin 13).
Dead-reckoning performance will be seriously impaired by errors or changes in the orientation of the EVK.
