During unpacking and installation, proper ESD handling procedures should be enforced. Maintenance The 1775 IMU is supplied as a sealed unit; there are no field maintainable components. Opening the enclosure will void the warranty and may violate the contract under which the unit was...
1775 IMU Technical Manual Output Orientation Output Orientation The 1775 IMU senses acceleration and angular velocity on three physical axes, as shown in Figure 3 and Figure 4. You may configure a rotation matrix to set the output axes relative to the physical orientation of these measurement axes, allowing the IMU to measure motion in three arbitrarily orthogonal axes (see “Configuration...

Figure 4 below shows the general physical location of the accelerometer axes and the location of the sensing point on each axis. Figure 5 describes the specific location of the accelerometer axes in Figure 4 for each 1775 IMU variant. Figure 4: Accelerometer Axes and Sensing Points Top View...
1775 IMU Technical Manual Interface Connector Interface Connector The 1775 IMU is equipped with a 15-pin (male) Micro-D interface connector of the following type: MIL-DTL-83513. Figure 6 shows the connector location. Figure 7 describes the function of each pin. For more information, refer to “Appendix C: Electrical Signaling ICD”...
When connected to the IMU, you can enter commands directly from the terminal or through a terminal emulation application. Use RS-422 differential signaling methods for all 1775 IMU digital control signals (KVH preferred). Alternatively, RS-422 single-ended signaling may be used if cabling susceptibility and other environmental interferences are proven acceptable.

(BIT) may be initiated by entering the “?bit” or “?bit,2” command. (Extended BIT data is also output whenever the IMU is first powered on.) The extended BIT provides six bytes of diagnostic data. The 1775 IMU records and reports stored BIT history as an optional diagnostic aid. For more information, refer to “Appendix C: Electrical Signaling ICD”...
1775 IMU Technical Manual Data Output Signal Processing Configuration Options The 1775 IMU offers more user configurable parameters than the KVH 1725 or 1750 IMU. These parameters can optimize the 1775 IMU performance for specific application need (e.g., faster update rates for...
1775 IMU Technical Manual Data Output Signal Processing You can query the current value of any parameter by entering the corresponding “?” command. For example, to view the current data rate, you would enter the “?dr” command. To enter any configuration command, the IMU must first be set to Configuration mode.
1775 IMU Technical Manual User Commands User Commands In addition to the configuration commands described in “Configuration Options” on page 14, the following commands are also available to the user. For more information, refer to “Appendix C: Electrical Signaling ICD” on page 31.
Time of Validity (TOV) Output Time of Validity (TOV) Output The 1775 IMU provides an optional RS-422 differential output on the external connector (named TOV-OUT+/TOV-OUT-) to indicate the time at which the data being output on the serial port can be considered to be valid.

7 (MSync (-)) and pin 11 (MSync (+)). The IMU’s output will be triggered on the rising edge of this master sync signal. The 1775 IMU master sync signal input supports both isosynchronous and non-isosynchronous signaling methods of transmission synchronization.
1775 IMU Technical Manual Hardware Restart TOV with Internal MSYNC Mode When the IMU is providing its own data output requests based on its internal source’s preconfigured rate, the unit outputs the differential TOV signal with a 10% duty cycle at the same frequency as the data output.
Mounting the IMU Mounting the IMU The 1775 IMU is easily mounted to a structure using the four 0.173" (4.39 mm) mounting holes on the base of the enclosure (see Figure 21). An alignment hole 0.198" (5.03 mm) and an alignment slot 0.218"...
This chapter explains how to diagnose basic problems. IMPORTANT! The 1775 IMU is supplied as a sealed unit. Breaking the QA seals voids the warranty and may violate the contract under which the unit was supplied. The warranty does not apply if the unit has been damaged by misuse or as the result of service or modification other than by KVH Industries.

Most users will not need to handle this as a special case, as the typical user requests data far faster than the 1/2 Hz limit. The 1775 IMU has a 90 µs hold off time from reception of one MSYNC to the next and this must also be taken into account.

12.2.6 Additional Information: Output Rate Resampling In the 1775 IMU family, the rate of the output of data to the user is configurable in a number of ways. It is, however, asynchronous to the internal sampling rate of both the gyro and the accelerometer sub-systems and it occurs at a lower data rate.
