Open Radar Initialize menu from [Menu] -> Initial Settings (f) and make radar settings.
Note:
If two or more chart radars are LAN connected, be sure to disconnect the chart radars from the LAN before hand to make radar settings individually.
4.1 RPU-016 Settings Setting Details Item Setting range Remarks CABLE ATT ADJ AUTO/ MANUAL 30 (:0 - 73)
The video signal level input into the control unit varies with the Antenna cable length between the Radar Processor unit and RF unit. This item is used for a compensation adjustment to the attenuation of the video signal level.
- AUTO： Automatically adjusted to an optimal level.
- MANUAL: Set GAIN to 80 and STC/FTC to OFF so that only a little noise will be generated.
HD ALIGN 000.0 (0-359.9)
Used to make heading marker adjustment in order to compensate the direction difference between a target and the echo of the target.
Make sure that the direction difference within 0.2°. Settings are processed on the basis of the Antenna HD pulse.
TIMING ADJ 1
(0-4095)
Makes adjustment of TX delay by the electrical circuit and antenna cable. Adjust range of echo so that a straight target such as a pier is presented as an straight picture on short range. Or makes adjustment so as to allow main bang of about 5 mm radius (20 inch monitor) or 7 mm (23 inch monitor) from the center on the 0.5 NM range when MBS (listed below) is set to “0”.
MBS 0
(0-255)
Used to make adjustment to Main bang
suppression (MBS). Make adjustment so that the MBS echo will be eliminated in an S1 range of 1.5 NM or below. DEFAULT ANT HEIGHT 5/7.5/10/ 15/20/25/ 30/35/40/ 45/ more 50m
Used to select the Antenna height from the sea surface, which influences the manual and automatic STC working ranges.
Reference:
The value is set as an initial value for [Menu] ->
PICTURE -> Condition: Ant Height.
NEAR STC
CRVE 2/2.5/3/3.5
MID STC CRVE 3/4/5/6 FAR STC
CRVE 6/7/8
STC curve slope settings, which usually need not be changed. The STC curve is set by this value and other factors, such as settings for [PICTURE]
->9: CONDITION and [Menu] ->0->4->6: MODEL.
Echo
RING
SUPPRESSION 1 (0-255)
Used to adjust to eliminate the ring-shaped image outside the MBS echo.
4.1 RPU-016 Settings START 000° BLIND SECTOR 1 ANGLE 000° START 000° BLIND SECTOR 2 ANGLE 000°
Used to stop transmission in specific directions. Set the target direction where transmission is stopped. Set START and ANGLE to 0° if transmission should be continued.
Antenna
REVOLUTION LO/HI/AUTO
Used to select 36 or 42 rpm provided that the RSB-097 (with a DC motor at 42 rpm) is used. - LO: 36 rpm; HI: 42rpm
- AUTO: HI when the transmission pulse width is S1 or S2, and LO when the transmission pulse width is M/L.
Reference:
The Antenna revolving speed is classified by Antenna motor model and PWR board. The type of Power supply board with 42 rpm specifications is 03Pxxxxx-B and D, with a D8G-571 motor used.
Antenna SW OFF/ON Used to turn antenna rotation ON/OFF. Usually turn this switch ON.
Scanner
Antenna
Stopd STBY/TX
Used to set ST-BY or TX when the antenna rotation stops.
EAV W/O
GYRO OFF/ON
Used to make EAV settings without HDG data. This item is provided on the assumption that the Radar is installed ashore.
Others
DEMO
ECHO OFF/EG
Used to select demonstration images. - EG：EG-3000/2000
RADAR MAIN/SUB
Used to make monitor (SUB) settings.
Transmission will be forbidden if this item is set to SUB.
The monitor signal is input into the terminal board: J616 (Master Radar) from the Master radar.
Installation
RADAR NO 1/2/3/4
The number of the local Radar (ANT) when the Radar is LAN connected.
When the number is set, turn the Chart radar system OFF and ON.
- Inter switch function:
LAN-connected Radar information can be checked with the [ANT INF] icon menu.
Note:
LAN-connected Radar numbers can be set to 1 to 4 (with the ANT unit provided).
Reference:
The Radar IP address can be checked with
[Menu] -> 0 -> 7: NETWORK on the RPU-016.
The IP address is interlocked with the radar number and allocated automatically.
4.1 RPU-016 Settings RADAR POSN FORE/ MAINTOP/ MAIN2ND/ MAIN 3RD/ AFT/ PORT/STBD
Used as a reference for the setting position of the Antenna. This information is displayed in the [ANT INF] icon menu.
Preset values are not used for signal processing.
Radar Model
6/12/25UP/ 25DOWN/ 50/30UP/ 30DOWN/60
Used for model settings. Make settings according to the RF unit.
Items, such as the transmission pulse waveform (MD board) and STC curve, changes according to the settings.
- X band：6/12/25UP/25DOWN - S band：50/30UP/30DOWN/60
Note: - UP： The RF is built into the Antenna unit.
- DOWN: The RF unit is installed externally. ON TIME 000000.0H
Used to display the total operating hours of the Radar.
The SPU board counts the time of power supply.
TX TIME 000000.0H
Used to display the total transmission hours of the Radar.
Used as a reference for the replacement of the magnetron. When the magnetron is replaced, reset this item to 0H.
The magnetron lasts for approximately 3,000 hours.
Transmission hours are counted on the SPU board.
PM GAIN
ADJ 0-255
Used to make performance (PM) gain adjustment. Range and signal processing settings will be automatically made for PM gain adjustment in this menu.
The PM echo is checked with [Menu] -> Echo ->
PM.
