The visible light camera is fixed to the railing of the ship’s radar mast.

The visible light camera is mounted on the camera housing, which secures the camera housing to the handrail. It will be a method of fixing and installing the pedestal of the camera housing between the handrails, and then installing the camera housing on top of it. The camera housing is not mounted directly on the pedestal, but is used on the camera housing mounting platform. The handrails and pedestal are fixed from the left and right sides and the bottom with U-bolts, and the pedestal and camera housing mounting base are bolted.

Camera housing mount drawings

Use U-bolts to secure the bottom three points of the pedestal and the center of the handrail. Fasten with double nuts.

Fix the left and right handrails and pedestals. Use long-legged U-bolts. Fasten with double nuts.

The pedestal and camera housing mount are fastened with 6 M8 bolts.

Note：

Visible light cameras are basically adjusted before shipping, but during on-site installation, there may be cases where the pedestal cannot be installed parallel to the hull or the pedestal cannot be oriented to match the heading of the ship. If this occurs, adjust the direction and angle of the visible light camera.

Each visible light camera is fixed to the camera housing mount at two points. Bolts use M5 and M8 nuts. Loosen this nut to adjust the direction of the visible light camera.

By aligning with the center of the moving part of each visible light camera, the angle difference between each camera will be 50 degrees. Make sure to orient the center camera to match the heading of the ship. For example, if you decide to shift the direction of the center visible light camera to the right by 2 degrees, please also shift the port and starboard sides by 2 degrees to the right.

Note：

If field adjustments do not allow three visible light cameras to be spaced 50 degrees apart, or if the cameras need to be pointed in different directions due to obstacles in their field of view, the camera angles can be adjusted in software.

In this case, record the camera orientation value.

Example：

To adjust the pitch angle of each visible light camera, loosen the M5 bolts (6 locations in total) on the left and right sides. Use a level to adjust it so that it is parallel to the pitch angle of the hull.

To adjust the roll angle of each visible light camera, loosen the bolts (7 locations in total) on the rear of the visible light camera. Use a level to adjust it so that it is parallel to the hull roll angle.

Basically, do not adjust the focus of the camera. Please perform the adjustment using the following method only if necessary due to the focus setting being incorrect.

　Focus adjustment must be done manually. There is a focus ring on the camera lens body, so turn it to adjust.

Remove the lens tube retainer that secures the camera. Using a hex wrench, remove the four screws on both ends and the two screws on the back.

　Then rotate and remove the lens tube.

　Removing the lens tube will expose the camera lens. The lens has two adjustment rings, and the outer ring is the focus ring.

　When adjusting the focus ring, it is equipped with a stopper screw to stop the ring from rotating, so loosen this screw and turn the ring. In the photo below, the ring is equipped with two stopper screws, but there may be only one.

　Focus adjustment is done while displaying the camera image on the iPad, but there is a slight time lag when displaying the image on the iPad. Check the image (focus check) by turning the ring little by little.

After adjustment, attach the removed lens tube and lens tube retainer.

The top plate is secured with six M8 extra low head screws. Please install it after adjusting the visible light camera.

Record the height of the visible light camera installed. Height is the height above the water surface.

Before installing the IMU, turn it on and rotate it ±2 rotations around each axis in the XYZ (yaw, roll, and pitch directions). By doing this, you can find out the minimum and maximum values of magnetic flux density, and you can calculate magnetic north.

Select 「起動設定．．．」 in the receiver menu.

Select "現在の設定で起動" for each item and press the OK button.

　When you press the OK button, the following message will be displayed, so please turn the IMU power off and on and restart it. If the following message is not displayed, repeat the startup settings again.

Since the IMU is used to measure the roll angle and pitch angle of the hull, please install the IMU in the same direction as the ship’s heading.

　If the IMU is misaligned and the inclination of the IMU is different from the inclination of the ship, you can adjust the offset of the IMU to match the inclination of the ship.

After entering the offset value, check the DMP/MB Gyro screen and adjust the level to match the inclination of the ship.

Select 「起動設定．．．」 in the receiver menu.

Select "現在の設定で起動" for each item and press the OK button.

　When you press the OK button, the following message will be displayed, so please turn the IMU power off and on and restart it. If the following message is not displayed, repeat the startup settings again.
