KVH Industries KVHTRACVISION G4 - Manual (Page 120)

9. Type HALT<cr>.
10. Type DEBUGON<cr> .
11. Type =LSTEST<cr>.
12. Type EL,300<cr>.
13. Type =CALGYRO<cr>. Verify that the Antenna
Gyro Azimuth scale factor is between -0.00090 and
-0.00110 and the Antenna Gyro Elevation scale
factor is between 0.00090 and 0.00110.
14. Type =SERNUM,<serial number><cr> , where
<serial number> = the system serial number that
you recorded in Step 2.
15. Type ZAP<cr> to restart/reinitialize the system.
If you have a GPS connected to the GyroTrac, no further action is
required. If you do not have a GPS connected to the GyroTrac,
KVH recommends that you complete the following steps to
speed satellite acquisition and improve system performance:
16. Type HALT<cr> while the system is performing
the limit switch initialization routine. The system
will complete the initialization function by finding
the azimuth and elevation switch limits and then
go to the home position.
17. Determine your vessel’s current latitude and
longitude to the nearest degree.
18. Type GPS,AA,B,CCC,D<cr> where:
• AA = Latitude in degrees
• B = N (North) or S (South)
• CCC = Longitude in degrees
• D = E (East) or W (West)
19. Verify that the response shows the correct
parameters.
20. Type ZAP<cr> to restart/reinitialize the system.
