    EVK-M8F User Guide The Antenna connector is only to be used with a GNSS antenna or simulator. Do not connect this equipment to cable distribution systems. 4.3.2 USB A USB V2.0 compatible serial port is featured for data communication and power supply. 4.3.3 UART The evaluation unit includes an RS232 port for serial communication that is compatible with PC serial ports.
  • Page 11 EVK-M8F User Guide For accurate measurements, it is recommended to use a cable of at most 1 meter in length. Figure 3 shows an example of a power supply connected to the test connector by using standard adapter cables from the manufacture Hirschmann.

    EVK-M8F User Guide 5 Measuring tracking current To measure the tracking current with EVK-M8F, follow these steps: 1. Connect a voltmeter capable of measuring average current across VCC and MODVCC of the front connector. (see Figure 4) 2. Wait 12 minutes to download all GNSS orbital data, or download all the Aiding Data via the AssistNow Online service 3.

    EVK-M8F-0-01 - User Guide 8 Troubleshooting My application (e.g. u-center) does not receive anything Check whether the blue LED on the evaluation unit is blinking. Also make sure that the USB cable is properly connected to the evaluation unit and the PC. By default, the evaluation unit outputs NMEA protocol on Serial Port 1 at 9600 Bd, or on the USB.
  • Page 18 EVK-M8F-0-01 - User Guide The EVK-M8F does not preserve the configuration in case of reset u-blox M8 GNSS technology uses a slightly different concept than most other GNSS receivers do. Settings are initially stored to volatile memory. In order to save them permanently, sending a second command is required.

    EVK-M8F-0-01 - User Guide 9 Common evaluation pitfalls • Parameter may have the same name but a different definition. GNSS receivers may have a similar size, price and power consumption but can still have different functionalities (e.g. no support for passive antennas, different temperature range).
