(RD) and navigation data from the xOEMcore, writes RD files and sends the navigation data out over serial and Ethernet interfaces. Model variations There are two models available in the xOEM series: the xOEM500 and xOEM550. Both systems use the xOEMcore with the same inertial sensors. The only difference is the GNSS receivers. ▪... -

The main connector for both xOEM models is a Samtec CLP-111-02-L-D. This is a 22 pin header with 1.27 mm spacing. The antenna connectors on the xOEM500 are MMCX. On the xOEM550 the antenna connectors are Hirose H.FL. Co-ordinate frame and origin point The xOEM uses a co-ordinate frame that is popular with most navigation systems. -
Page 14: Design-In
Design-in Main connector OxTS recommends that you mount directly to the xOEM with a connecting board using Samtec FTSH-111-02-L-D. 5 mm space should be left between the mounting points for the xOEM and the mounting points for the mating board to allow room for the two connectors. Alternative mating connectors are available from Samtec or from alternative suppliers. -

Limited protection is provided on this input, however the input voltage should not exceed 12 V. Antennas The xOEM500 GNSS modules receive L1 GPS signals at a nominal frequency of 1575.42 MHz, and can receive L1 GLONASS signals at 1602.0 MHz. Antennas used with the xOEM500 must be capable of tracking this signal for correct operation. -
Page 17: Mounting
Mounting Figure 9 and Figure 10 show the mounting points and required clearances for the xOEM500 and xOEM550 respectively. It is important when mounting the xOEM board sets not to stress the IMU mechanically in any way as this can change the alignment of the sensors and degrade the calibration. -

Page 20: Heat Dissipation
As with other electronic devices the power consumption of the xOEM is affected by the environmental conditions it is operating in and by its power source. Tests carried out by OxTS have shown that the best power consumption is achieved with a 12 V power input and at room temperature (20–25°C). It is also recommended to not use excessively long antenna or power cables to reduce power loss in cabling. -
