A hardware change by KVH regarding KVH1750 IMUs (manufactured after November 2015) expect a differential MSYNC signal input (J1 (15 pin micro D female) of the IMU: Pin 11 MSync+, Pin 7 MSync-). This was previously a single ended input signal on Pin 11 only. The NovAtel VARF signal used to provide the MSYNC to the IMU remains single ended, however significant testing has been completed with the existing IMU-KVH1750 Cable (01019211) in safe environments (no interference sources). No issues or failures have been observed. There are no plans to modify NovAtel cables at this time. However, for any custom or OEM cable solutions, it is recommended to follow KVH guidelines in providing a differential MSYNC signal, converting the VARF to differential and properly shielding for optimal reliability.
