a. For the IMU-ISA-100C, IMU-HG1900, IMU-ENC-LN200 or IMU-µIMU-IC, use the IMU Enclosure
Wheel Sensor cable (60723137), or a custom cable, to connect the DMI to the Wheel Sensor port on
the IMU. See
IMU Enclosure Wheel Sensor Cable
on page 179 for information about the cable or for
information about creating a custom wheel sensor cable.
b. For the IMU-IGM-A1 or IMU-IGM-S1, use a custom cable to connect the DMI to the AUX port on the
IMU. Refer to
on page 163 for the pin out of the IMU-IGM AUX port.
The SPAN-IGM Auxiliary Port interface cable (01019015) can be used to connect the wheel sensor
inputs to the IMU-IGM. However, when this cable is used with an IMU-IGM, only the wheel sensor
inputs are available. The other connectors on this cable do not have connections to the IMU or receiver.
c. For the IMU-FSAS or IMU-CPT, connect the DMI to the wheel sensor inputs on the IMU interface
cable. Use the IMU-FSAS Cable with Wheel Sensor or a custom cable that provides access to the
wheel sensor inputs. See the
IMU-FSAS Cable with Wheel Sensor
on page 152 for more information.
3. Connect an external power supply to the DMI.
The power required for the DMI depends on the DMI used. Refer to the DMI user documents for more inform-
ation.
Configure the DMI
1. Send the following command to enable a DMI on the IMU wheel sensor inputs.
DMICONFIG DMI1 ENABLE IMU
2. Send the following commands to log the DMI data.
LOG DMICONFIGA ONCHANGED
LOG RAWDMIA ONNEW
LOG INSUPDATESTATUSA ONNEW
3. Check the
RAWDMI
log to ensure the DMI is producing data.
4. Check the
INSUPDATESTATUS
log to ensure the DMI is being used in the SPAN solution.
If there is no DMI data being produced or the DMI status is not USED, refer to
Refer to the
OEM7 Commands and Logs Reference Manual
for information about the commands and logs used
in this section.
