iIMU-FSAS Odometer Cabling
The iIMU-FSAS with the –O wheel sensor option provides wheel sensor input from the Distance
Measurement Instrument (DMI) through the DB-9 connector labelled “ODO” on the IMU interface
cable. The IMU data goes through the IMU and then into the SPAN receiver through the serial
communication line.
There are two DMI products that are compatible with the iIMU-FSAS system:
• iMWS-V2 (Magnetic Wheel Sensor) from iMAR
- A magnetic strip and detector are installed inside the wheel. The signal then
goes through a box that translates the magnetic readings into pulses that are
then passed through the cable into the ODO connector on the IMU cable. See
also
below.
• WPT (Wheel Pulse Transducer) from Corrsys Datron
