OEM-IMU-µIMU-IC / OEM-IMU-µIMU-IC-UART

The specifications in this section apply to both the OEM-IMU-µIMU-IC and OEM-IMU-µIMU-IC-UART.

The OEM-IMU-µIMU-IC requires a Universal IMU Controller to connect to a NovAtel receiver. See UIC – Universal IMU Controller.

OEM-IMU-µIMU-IC / OEM-IMU-µIMU-IC-UART Comparison

While the OEM-IMU-µIMU-IC and OEM-IMU-µIMU-IC-UART provide the same SPAN performance, there are differences in how the IMU is integrated into the SPAN system.

	OEM-IMU-µIMU-IC	OEM-IMU-µIMU-IC-UART
Communication connection	The UIC provides the communication interface between the IMU and receiver.	The IMU connects directly to a receiver serial port.
Input voltage	The UIC provides power to the IMU. The UIC requires 10 – 34 VDC. See UIC Electrical and Environmental.	The IMU requires 5 VDC.
Power consumption	<8 W + 4W for the UIC	<8 W
DMI input	Yes. DMI input is handled by the UIC.	No. Requires manual input of wheel ticks using the RAWDMI command.
Event Signals	The UIC handles timing with the IMU.	Requires the SYNCOUT signal on the IMU to be connected to an EVENTIN on the receiver. (EVENTIN2 is the default)
Cables	An IMU to UIC cable is available from NovAtel. See OEM-IMU-µIMU-IC to UIC Cable Assembly.	A cable is not available from NovAtel. A Micro-D 31 connector is required on the IMU end of the cable.
