![7─11 7.2 NAVIGATOR SETTING This section describes the electrical adjustment procedures to be performed by service engineers during system installation. Make an appropriate setting for each type of equipment when inputting true bearing signals, true bearing data, and speed data. Settings and parameters are different for each type of equipment. Make settings for the type of equipment to be connected. [I] Inputting analog true bearing signals from a gyro system through synchronization and steps By following the procedure described in the INSTALLATION MANUAL, connect the optional NSK unit (NCT-4106A) to this equipment. Then, follow the steps below to make settings. In Section 7.2.1 “Ship Heading Equipment Setting (Heading Equipment),” select 1: GYRO (NCT-4106A, JLR10, JRL20/30). By referring to Section 7.2.2 “NSK Unit Setting,” make a setting for the gyro system. By referring to Section 7.2.3 “True Bearing Value Setting (Set GYRO),” make a setting such that the gyro azimuth and the radar azimuth are the same. Refer to an applicable page for details. CAUTION Do not carry out the adjustments of the equipment except authorized service persons. If wrong setting is carried out, this may cause unstable operation. Do not carry out the adjustments during navigation. Otherwise, the radar performance may be affected, resulting in an accident or trouble.](https://usermanual.wiki/Japan-Radio/NKE2062.Users-Manual-4/User-Guide-1377755-Page-1.png)
![7.2 NAVIGATOR SETTING 7─12 7yyyyyyy[II] Inputting digital true bearing signals from a gyro system (IEC61162, NMEA0183) By following the procedure described in the INSTALLATION MANUAL, connect the gyro system to this equipment. Then, follow the steps below to make settings. In Section 7.2.1 “Ship Heading Equipment Setting (Heading Equipment),” select 2: COMPASS (IEC61162). In Section 7.3.1.1 “Baud Rate Setting,” select 5. COM5 (COMPASS). Select either 38400 bps or 48000 bps depending on the data baud rate outputted from the GPS compass. (*) For digital signal output from the gyro system ・ Select 38400 bps if possible. A higher baud rate means shorter data output cycle, which results in better course following performance. ・ If the system allows setting of data output cycle, set it to 10 ms to 20 ms. A longer data output cycle results in lower course following performance. This may affect the radar performance level and the target tracking performance level. Refer to an applicable page for details. [III] Inputting true bearing data from GPS Compass JLR10 or JLR20/30 By following the procedure described in the INSTALLATION MANUAL, connect GPS Compass JLR10 or JLR20/30 to this equipment.

True bearing value setting described in Section 7.2.3 is not required when using the GPS compass. If the GPS compass azimuth and the radar azimuth are not the same, use the GPS compass to adjust the azimuth. Refer to an applicable page for details. [IV] Inputting digital true bearing data from a GPS compass (other than JLR10 and JLR20/30) or other true bearing systems (IEC61162 or NMEA0183) By following the procedure described in the INSTALLATION MANUAL, connect a GPS compass or other true bearing system to this equipment. Then, follow the steps below to make settings. In Section 7.2.1 “Ship Heading Equipment Setting (Heading Equipment),” select 2: COMPASS (IEC61162). In Section 7.3.1.1 “Baud Rate Setting,” select 5. COM5 (COMPASS). Select either 38400 bps or 48000 bps depending on the data baud rate outputted from the GPS compass. (*) For the GPS compass or other true bearing systems ・ Select 38400 bps if possible. A higher baud rate means shorter data output cycle, which results in better course following performance. ・ If the system allows setting of data output cycle, set it to 10 ms to 20 ms.
