Chapter 2 Installation of OEM7 Family Receiver CardsOEM7 Installation and Operation User Manual v4 46If the Ethernet port is being routed outside of the enclosure, an interface circuit is needed. Foran example of an Ethernet interface circuit, see Ethernet Port on page 223.See OEM729 Technical Specifications on page 146, OEM7700 Technical Specifications onpage 166 and OEM7720 Technical Specifications on page 189 for further information on Ethernetspecifications and pin assignments.Ethernet is not available on OEM719 receivers.Refer to Ethernet Configuration on page 91 for instructions on configuring Ethernet and NTRIP.2.11.4 SPI PortsThe Serial Peripheral Interface (SPI) port provides communications to specific, supporteddevices in the GNSS system. The OEM7 functions as a SPI host and cannot be interfaced as a SPIDevice. For example, the OEM7 receiver can use the SPI port to communicate with some IMUsin a SPAN system. Here is a list of the currently supported devices:l OEM-IMU-ADIS-16488l OEM-IMU-EG320NA SPI port is only available on OEM7700 and OEM7720 receivers.2.12 Check that the Receiver is OperatingAfter the receiver is installed, powered up and connected to a GNSS antenna, use the followingprocedure to ensure the receiver is operating.1. Check the LED Status Indicator is blinking green at 1 Hz.See Preparing the Data, Signal and Power Interface on page 33 for the location of the LED.2. Send the following command:LOG VERSIONThe VERSION log is returned.

Check that the Time Status is FINESTEERING which represents that time is fine set andbeing steered.4. Check the Receiver Status word (02040020 in this example). If the farthest digit is 1, thereceiver has errors.
