Notes:
(*1) Specification of vehicle speed pulse and reverse signal
Please check the regulation and electric characteristics by GNSS+DR receiver data sheet and keep it,
otherwise customer may have risk of out of performance guarantee. It is necessary to take vehicle speed pulse
together reverse signal.
(*2) Supported IMU sensor
We verified that GNSS+DR receiver with sensor in Table 3.2 could achieve target performance by proper
calibration described at Chapter 6.
(*3) In case of using XV-8000CB, it is necessary to implement the following devices.
-AD convertor (ADS1100A3: Texas Instruments)
-Thermo sensor (LM73CIMKX-0: Texas Instruments)
-Level shifter from 5V to 3V
(*4) In case of using XV-8100CB, it is necessary to implement the following devices.
-AD convertor (ADS1100A3: Texas Instruments)
-Thermo sensor (LM73CIMKX-0: Texas Instruments)
