[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. 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).
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.
A longer data output cycle results in lower course following performance. This may affect the
radar performance level and the target tracking performance level.
