Complete the following steps to connect and power your MIC and OEM615.  
Assemble in accordance with applicable industry standards. Ensure all Electrostatic Discharge  
(ESD) measures are in place, in particular, use a ground strap before exposing or handling any  
electronic items, including the MIC, receiver and IMU. Take care to prevent damaging or  
marring painted surfaces, O-rings, sealing surfaces and the IMU.  
For more information about ESD practices, see the OEM6 Family Installation and Operation  
User Manual available from our website at www.novatel.com.  
1. Attach the IMU mounting PCB to the IMU.  
Ensure all the pins on the header are aligned with the holes on the mating connector.  
An IMU mounting PCB is not used with the STIM300 IMU.  
2. Mount the IMU and antenna securely to a vehicle.  
For the simplest operation, align the Y-axis of the IMU with the forward axis (direction of travel) of the  
vehicle. Ensure the Z-axis is pointing up.  
Ensure that the GNSS antenna and IMU cannot move relative to each other. The distance and relative  
direction between them must be fixed.  
For center of navigation diagrams of the ADIS and STIM300 IMUs, see the SPAN on OEM6  
User Manual available from our web site at www.novatel.com.  
For center of navigation diagrams of the HG1700, HG1900 and HG1930 IMUs, contact  
NovAtel Customer Support. See Questions or Comments on page 12 for contact  
information.  
3. Use the standoffs supplied with the MIC to mount the OEM615 receiver in a secure enclosure to  
reduce environmental exposure and RF interference. See the OEM6 Family Installation and Operation  
User Manual for information about mounting printed circuit boards.  
The part number for the standoffs included with the MIC is RAF-M21073005AL7 (Irwin  
Industrial).  
If alternate standoffs are selected, use equivalent parts with a minimum height of 12 mm.  
 
4
Ensure all standoffs are properly installed and the mounting location for the receiver is level.  
The amount of board deflection (bow and twist) must not exceed 0.75%. For example, on  
the OEM615 which is 71 mm long and 46 mm wide, the deflection along the length must not  
exceed 0.53 mm and the deflection along the width must not exceed 0.34 mm.  
4. Connect the antenna cable to the antenna jack (J101) on the OEM615.  
The antenna cable must have a right angle MCX connector on the end that connects to the OEM615.  
Do not apply power to the cards until the antenna cable is attached.  
The part number for the recommended MCX connector is  
M1051-110 (ShinA Telecom). If an alternate is used part, it  
should meet the dimensions shown in the diagram.  
The space between the OEM615 and the MIC is limited. The  
height of the MCX connector must not exceed 8.65 mm.  
5. Align the OEM615 mating connector (J301) on the MIC with the 20-pin header (P1101) on the OEM615.  
Make sure all of the pins on the header are aligned with the holes in the mating connector.  
Press down on the MIC to seat the connector on the header.  
6. Use the four screws supplied with MIC to secure the MIC to the OEM615.  
7. Connect the IMU-to-MIC interface cable to the IMU.  
8. Connect the IMU-to-MIC interface cable to the IMU connector on the MIC.  
Use the 10-pin locking connector (P701) for the ADIS IMU.  
Use the 20-pin locking connector (P601) for the HG1700, HG1900, HG1930 or STIM300 IMU.  
9. Using a customer supplied wiring harness, connect a +10 to +30 V DC power supply to the power  
connector (P101) on the MIC. This connection provides power to the MIC and the OEM615.  
See the SPAN on OEM6 User Manual for pin out information for the power connector.  
10. Using a customer supplied wiring harness, connect the communications connector (P301) to the user  
system.  
In a stack up configuration, the P301 connector provides connections for the: MIC serial port, OEM615  
serial port (COM2), USB port, Event1 trigger, Event2 trigger, 1 Pulse Per Second (PPS) output,  
Variable Frequency (VARF) output, Reset Input and Position Valid output.  
See the SPAN on OEM6 User Manual for pin out information for the communications connector.  
All signal I/O with the exception of the USB port are at LVTTL levels.  
To connect the MIC to devices that use other signals levels, such as a computer with an  
RS-232 serial port, an interface circuit that converts to and from LVTTL must be used.  
Use a twisted pair for the USB port connection and keep the wires as short as possible.

3. Enter the distance from the IMU to the GNSS antenna using the SETIMUTOANTOFFSET command.  
The X (pitch), Y (roll) and Z (azimuth) directions are clearly marked on the IMU enclosure. The  
SETIMUTOANTOFFSET parameters are (where the standard deviation fields are optional):  
x_offset y_offset z_offset [x_stdev] [y_stdev] [z_stdev]  
This example assumes a default mounting configuration with a -X offset, -Y offset and +Z  
A typical RTK GNSS solution is accurate to a few centimetres. For the integrated GNSS/INS system to  
offset.  
have this level of accuracy, the offset must be measured to within a centimetre.  
4. Perform a kinematic alignment.  
See the SPAN on OEM6 User Manual for more information.  
LOG SPAN DATA  
Navigation data (position, velocity, attitude) is available from the system as ASCII or binary logs.  
Data can be collected through NovAtel Connect using the Logging Control Window, or sent out the  
receiver COM port to user supplied data collection software.  
The figure shows the recommended logs for optimal real-time performance.  
 
10  
OPERATE THE SPAN SYSTEM  
The system is ready to go once it is powered and the INS and GNSS are configured using the previously  
shown commands.  
Observe the status of the system in the NovAtel Connect INS Window or in the status field of any of the  
INS solution logs (for example INSPOS, INSVEL, INSATT and INSPVA).  
INS data is available once there is a good GNSS solution. Therefore, an antenna must be  
connected for the system to function.  
If performing a static alignment, allow the system to be stationary for at least 1 minute after the GNSS  
solution is computed for its initial system alignment. If performing a kinematic alignment, move the vehicle  
forward at a speed faster than 5 m/s. The following status stages may be observed:

INS_ALIGNING  
INS is in alignment mode.  
The INS solution is still being computed but the azimuth  
solution uncertainty has exceed 2 degrees. The solution  
is still valid but you should monitor the solution  
uncertainty in the INSCOV log. You may encounter this  
state during times when the GNSS, used to aid the INS,  
is absent.

INS_SOLUTION_GOOD  
INS_SOLUTION_FREE  
The INS filter is in navigation mode and the GNSS  
solution is suspected to be in error.  
This may be due to multipath or limited satellite visibility.  
The inertial filter has rejected the GNSS position and is  
waiting for the solution quality to improve.  
The INS filter is in navigation mode, but not enough  
vehicle dynamics have been experienced for the system  
to be within specifications.
