IMU-CPT, IMU-KVH1750 and IMU-FSAS
These IMUs require an additional output from the receiver to synchronize the IMU and receiver.
l
IMU-CPT
Connect the EVENT_OUT1 (VARF) signal from the receiver to the External Clock Input signal (pin
36) on the IMU-CPT. Refer to the
on page 145 for information about the cable
requirements for the IMU-CPT.
l
IMU-KVH1750
Connect the EVENT_OUT1 (VARF) signal from the receiver to the MSync signal (pin 11) on the
IMU-KVH1750. Refer to the
on page 188 for information about the cable
requirements for the IMU-KVH1750.
l
IMU-FSAS
Connect the EVENT_OUT1 (VARF) signal from the receiver to the DAS(+) signal (pin 7) on the
IMU-FSAS. Refer to the
IMU-FSAS Cable with Wheel Sensor
on page 152 for information about
the cable requirements for the IMU-FSAS.
l
OEM-IMU-STIM300D
Connect the EVENT_IN2 signal from the receiver to the TOV signal (pin 4) on the OEM-IMU-
STIM300. Refer to
OEM-IMU-STIM300 Direct Connection
on page 237 for more information.
OEM-IMU-STIM300D
The OEM-IMU-STIM300D requires an additional input from the receiver to synchronize the IMU and
receiver.
Connect the EVENT_IN2 signal from the receiver to the TOV signal (pin 4) on the OEM-IMU-STIM300.
Refer to
OEM-IMU-STIM300 Direct Connection
on page 237 for more information.
The interface between the OEM7 receiver card and IMU must include circuitry to convert from the
LVCMOS signal levels of the receiver COM port to the RS-232 or RS-422 signal levels of the IMU COM
port.
The exception is COM1 on the OEM729 which provides either RS-232 or RS-422 signal levels.
If using a KVH1750 IMU not purchased through NovAtel, the baud rate of the IMU must be changed to
460,800 bps and the output method changed to MSYNC,EXT. For information about changing these
parameters, see
Connect an OEM IMU to an OEM7 Receiver Card Using a UIC
The UIC provides power to the IMU and communication between the IMU and receiver. For information about
using a UIC, see
Connect an OEM IMU to an OEM7 Receiver Card Using a MIC
The MIC provides power to the IMU and communication between the IMU and receiver. For information about
using a MIC, see
