Figure 2-24 GyroTrac Sensor Connector Sensor Cable Connector 2. Connect the other end of the sensor cable to the blue ADCU terminal strip connector as shown in Figure 2-25.
TracVision G4 Technical Manual Connecting External Devices to the ADCU (Optional) GyroTrac can be integrated with many types of onboard equipment, including autopilots, radars, remote displays, plotters, global positioning systems (GPS), and computers. All connections between the ADCU and external devices are made at the terminal strip connectors located on the rear of the ADCU.
Installation Connecting the Sine/Cosine Interface (Optional) The GyroTrac ADCU sine/cosine interface provides the following outputs: • sine • cosine • inverse sine • inverse cosine • reference voltage Green Label 1 2 3 4 5 6 7 8 9 Figure 2-26 Sine/Cosine ADCU Wiring 10 11 12 Sine Sine (inverted) Cosine Cosine (inverted) Ref Ground Because the reference voltage is a reference output, not an input, connecting this output to another reference output from an autopilot or other system will
TracVision G4 Technical Manual To adjust the GyroTrac reference to match the reference of the autopilot (or other system), connect a voltmeter to GyroTrac ADCU terminal (#8) and the reference terminal of the autopilot (or other system). Adjust the GyroTrac reference voltage as described in “Setting the Sine/Cosine Data Output” on page 69 until the voltmeter indicates 0 VDC. The sine/cosine interface should now operate with optimal precision.
Installation Connecting the ADCU to Vessel Power Short circuits may result in severe electrical shock or burns. Turn off vessel power and test the circuit to ensure that no power is present before connecting any power cables. Do NOT reapply power until all system wiring is completed and all terminal strip connectors are installed on the ADCU rear panel, as described in “Connecting the Terminal Strip Connectors to the ADCU” on page 38. The TracVision G4 system requires an 11-16 VDC power input.
TracVision G4 Technical Manual Connecting the Terminal Strip Connectors to the ADCU Now that you have connected all wires to the terminal strip connectors, insert the connectors into the ADCU’s rear panel as shown in Figure 2-29. Figure 2-29 Attaching the Terminal Strips to the ADCU & ' ! " # $ % Double-check all wiring. Be certain to plug terminal strips into the correct positions.
Installation Effective Strain Relief for ADCU Terminal Connections Due to both the potential number of wires that connect to the rear of the ADCU and the dynamic environment aboard ship, it is critical that the terminal connections be properly strain-relieved using tie-wraps (a number of which are included in the GyroTrac kitpack). Some things to consider when strain-relieving wires: • There should be no tension on the wires connecting to the terminal strips.
TracVision G4 Technical Manual 2.7 Calibrating the Sensor Every sensor module is calibrated at the factory in a perfectworld environment. However, hard and soft iron effects on your vessel can distort the local magnetic field, causing errors in the reported heading. These errors are minimized by mounting the sensor module in a suitable location and are further removed by GyroTrac’s autocalibration feature, which compensates for minor magnetic distortions.
Installation The Calibration Score Each calibration results in a calibration score that is stored in the system’s memory. Figure 2-32 Sample Calibration Score Screen Magnetic Environment Accuracy Calibration Update Number ACC CAL<1° MagEnv GOOD Cal# 3 Table 2-7 Possible Compass Accuracy Levels Accuracy (ACC) The ACC data indicates the degree of accuracy the GyroTrac will provide based on the quality of the last calibration. Table 2-7 lists the five possible accuracy levels.

Troubleshooting 4.1 Troubleshooting Matrix The troubleshooting matrix shown in Table 4-1 identifies some trouble symptoms, their possible causes, and references to troubleshooting solutions.
TracVision G4 Technical Manual 4.2 Causes and Remedies for Common Operational Issues There are a number of common issues that can affect the performance of the TracVision G4. The following sections address these issues and potential solutions. Blown Fuse, Low Power, or Improper Wiring Blown Fuse The antenna unit is equipped with two fuses mounted on its main printed circuit board (PCB). The ADCU is equipped with one fuse mounted on its upper PCB.
Troubleshooting Incorrect Satellite Configuration (European Systems Only) The satellite configuration on European IRDs must match the satellite settings on the TracVision G4 system. • Satellite A on the TracVision G4 must be the same satellite as IRD Alternative 1 (or A, based on your IRD) and must be assigned the IRD DiSEqC 1 setting. • Satellite B on the TracVision G4 must be the same satellite as IRD Alternative 2 (or B, based on your IRD) and must be assigned the IRD DiSEqC 2 setting.
TracVision G4 Technical Manual Satellite Frequency Data Changed If some channels work, while one or more other channels do not, or the antenna cannot find the satellite, the selected satellite’s frequency data may have changed. To update this frequency data, refer to “Updating Satellite Frequency Data” on page 88. Incorrect or Loose RF Connectors As part of preventive maintenance (described in Section 5.2, “Preventive Maintenance” on page 103) KVH recommends checking the antenna unit’s cable connections.
Troubleshooting 4.3 GyroTrac-specific Issues The GyroTrac is designed for reliable, easy use. This section provides a brief overview of some potential operational issues. Issue 1: System is installed correctly and power is available, but the system is non-functional. Figure 4-1 ADCU Fuse Location (Top Cutaway) Solution: Check the 4-amp fuse within the ADCU. Remove the two screws securing the top and the base of the ADCU, and remove the ADCU’s top cover.
TracVision G4 Technical Manual Issue 4: There is no data output through Serial Port #3. Solution: Serial Port #3 provides no output when GyroTrac is configured as a component within a GyroTrac-compatible TracVision system. 4.4 IRD Troubleshooting The IRD that was provided with your satellite television service may also be the cause of less-than-ideal operation. First check the IRD’s configuration to ensure it is set up for the desired programming.
Troubleshooting The diagnostics procedure requires Windows Hyperterminal (or other terminal emulation software, such as PROCOMM). Use the settings appropriate to your application. 1. Connect one end of the PC data cable to the DB9 maintenance port connector on the rear of the ADCU. Connect the other end to the serial port on your PC (a 9-pin/25-pin connector adapter may be needed for some PCs).
