C93-M8E installation
The following sections describe the steps required to complete the C93-M8E hardware installation.
4.1.1
Mounting the C93-M8E
The C93-M8E application board should be firmly attached to the car body so as to avoid any
movement or vibration with respect to the car body. The application board 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 C93-M8E casing. The C93-M8E must be secured
against any change in position and particularly orientation with respect to the vehicle frame.

For best performance, the integrated antenna needs to have the best sky view possible in the car
or outside of the car.
4.1.2
Connecting the cables
Rather than using USB alone, we recommend using the 6-pin latching receptacle recommended
above, because it locks securely to the front connector of the C93-M8E. Other 0.1" receptacles may
be compatible. You will need to solder the necessary I/O cables to signal sources and outputs as in
Table 3.
1.
Connect the unit to a PC running Microsoft Windows by
1.1.
USB: Connect via USB port or
1.2.
UART: Connect via 6-pin header via an inverting RS-232 level shifter (e.g. MAX3232).
2.
The device is powered either via USB or from a 5 V supply via Pin #1 of the 6-pin header.
3.
Start the u-center GNSS Evaluation Software and select the corresponding COM port and baud
rate.
