SPI Ports

The Serial Peripheral Interface (SPI) port provides communications to specific, supported devices in the GNSS system. The OEM7 functions as a SPI host and cannot be interfaced as a SPI Device. For example, the OEM7 receiver can use the SPI port to communicate with some IMUs in a SPAN system. Here is a list of the currently supported devices:

  • OEM-IMU-ADIS-16488

  • OEM-IMU-EG320N

  • OEM-IMU-EG370N

A SPI port is only available on OEM7500, OEM7600, OEM7700 and OEM7720 receivers.
