     Installing MD-Series Systems
    Installation Planning
    Caution: The installation requires some fam iliarity with electrical connections, 
    cabling, sealing, and proper mounting practices. If you do not have this 
    background, consider having the MD-Series camera installed professionally. In 
    addition, there are several choices in how  the camera is mounted and cabled. If 
    the more complex installation options are used, such as mounting from the top 
    and creating cable connections within the ca mera dome, it is especially important 
    to have professional assistance. 
    Installation Options
    There are several options for installing  and using the MD-Series camera that 
    affect the complexity of the installation and the steps required. 
    • One set of options relates to the posi tion of the cable connections: inside or 
    outside the camera dome. 
    • The other has to do with how the camera is mounted: with mounting bolts  coming up from beneath or down from the top of the mounting plate.
    The most straightforward approach, and the  one that is recommended, is to install 
    the camera with bolts from below and the cables connected outside the dome. 
    This configuration is ideal if the vessel  has a simple cover such as a T-top. The 
    cables can be tied back as needed. Altern atively it is possible to install the 
    camera from above on the superstructure or hardtop of a vessel. In either 
    location, it is also possib le to configure the cable connections within the camera 
    dome. Doing this requires a number of additional steps. 
    External or Internal Connections  
    As delivered, the cables on the MD-Series camera extend 
    through the base (shown on left). It is a simple, 
    straightforward process to connect these cables to the 
    supplied longer cables.
    Optionally, as shown in the right-hand picture, the 
    connections can be made within the camera dome by 
    bringing the longer cables up through the base and making 
    the required interior cable connections. 
    Mounting Bolt Direction
    Generally the MD-Series camera is secure d directly to a surface using threaded 
    studs that extend from the base through the mounting platform and that are 
    secured from below. If it is not possible to access the space below the mounting 
    platform, the camera can also be mount ed in a similar top-down fashion by drilling 
    through the base in four predetermined lo cations, mounting it directly to the 
    surface. When using this method, it is necessary to seal around the fasteners 
    using a marine grade sealant (3M 4200 or  equivalent) to prevent leakage into the 
    mounting structure.

    Ball-Up and Ball-Down Installation
    In most installations, the MD-Series camera unit is mounted upright (ball up) on 
    top of a mounting surface, with the base below the camera. Optionally, the unit 
    can be hung upside down or ball down and configured to invert and revert the 
    video output by selecting Enable Ball-Down  Installation under System Settings of 
    the camera on-screen menu system. See the  MD-Series Operator’s Manual for 
    details.
    Unless otherwise noted, this manual assumes an upright installation.
    Location Considerations
    It is important to determine a good location for mounting the MD-Series camera 
    unit. The camera requires two connections:
    • One for power and camera control
    • One for the video display 
    When determining the location, consider how the system may be expanded in 
    the future. Optionally, either a JCU or wireless device can be used to control the 
    camera and more than one display can be used to view the video. 
    These are important points to consider when determining the camera location:
    • Make sure the mounting location is le vel and is at least as large as the 
    footprint of the camera. To ensure a proper seal between the camera unit and 
    the vessel, an O-ring is installed in  the camera base, which will seal properly 
    with a surface that is flat to within 0.25  mm (0.010 in) over the diameter of the 
    base of the camera. Use a short straight edge such as a six-inch ruler to 
    confirm the surface is flat and the  edge makes contact along the entire 
    surface.
    Note:  If it is necessary to install on a surface that does not meet that criteria, a 
    marine-grade sealant (3M 4200 or equivalent) must be used rather than the 
    O-ring.
    • Make sure the camera is placed close  enough to the mounting edge that the 
    camera field of view is not obstructed  by the platform. This is especially 
    important if the camera  will be tilted downward.
    • Mount the MD-Series camera body as high as practical, but without interfering  with any radar, navigational, or communications electronics and minimizing 
    the degree to which vessel structures block the camera’s view. It is good 
    practice to test the unit at the planned  installation location with typical vessel 
    electronics active prior to mounting the camera. 
    • Ensure a clearance of at least double the  overall height of the camera in order 
    to allow for dome removal. 
    • To maintain situational awareness, a good general practice is to mount the  camera so that a small portion of the ve ssel is visible at the bottom of the 
    video image as a reference point and that no more that 30% sky is visible in 
    the video image.

     Installing MD-Series Systems
    • Ensure the camera mount is suitable for the camera mass and that potential vibration and mechanical shock is mini mized. The camera is tested to hold 
    position for mechanical shock up to 9g transverse and 15g vertical. Improper 
    mounts that are loose and/or resonate  can magnify vessel impacts causing the 
    camera to be unable to maintain pointing direction.
    • Consider the camera’s location relative to other navigation devices. If a  magnetic compass is used for navigation and direction, establish a “compass 
    safe distance” for any object placed in  its vicinity, especially any electronic 
    equipment. The magnetic compass safe distance for the camera is 7 cm (2.75 
    in) and for the PoE inject or is 11 cm (4.33 in).
    • Verify that both sides of the mounting surface are accessible. 
    • Consider the thickness of the mounting platform. With the supplied hardware,  the camera can be mounted to a platform  that is up to 41 mm (1.6”) thick. 
    Depending on the thickness of the mounting platform, it may be necessary to 
    provide other mounting hardware, rather than using the supplied threaded 
    studs and nylock nuts and acorn nuts. 
    • Ensure the supplied coaxial and Ethernet cables are long enough, given the  proposed mounting locations and cable routing requirements. It is a good idea 
    to route the cables before beginning the physical installation to verify correct 
    length. 
    Camera Settings
    The MD-Series has a number of settings that can be tailored using on-screen 
    menus. These settings are fully described in the  MD-Series Operator’s Manual. 
    To change the system settings requires  the use of a wireless device, a direct 
    connection with a PC, or the installation of  an optional JCU. If one of these is not 
    available on the vessel when the came ra will be used, consider setting up the 
    camera at the time of installation. 
    For example, connect a PC or laptop  to the camera’s Ethernet connection
    1. Then 
    it will be possible to make any setup  changes from the PC a web browser. 
    Proper Grounding
    As part of the installation, ensure the ca mera is properly grounded. Following best 
    grounding practices, the camera chassis gr ound should use the lowest resistance 
    path possible.
    A dedicated stud located on the bottom of  the MD-Series near the cable egress 
    points provides chassis ground for a hi gh conductivity path to vessel ground 
    (maximum 0.25 Ohm). The installer must provide the grounding strap and ring 
    terminal for the connection. A nylock nut is provided to secure the strap. The ring 
    terminal is typically sized for #6 or M3 stud and 14 to 16 gauge wire. If using a 
    1 Connect the camera to the end of the PoE  injector with the warning and then connect an 
    Ethernet cable from the othe r end of the PoE injector to a PC or laptop. Connect DC 
    power to the PoE injector’s terminal block.

    different ring terminal, make sure that its size does not interfere with the camera 
    mounting.
    Failure to provide this connection may result in electrical interference between 
    the camera and other shipboard electr onic systems. Furthermore, it is 
    recommended that a bonded grounding scheme is used with a common ground 
    between the chassis ground and electrical return, with the connection made as 
    close as possible to the negative terminal of the battery. 
    Physical Installation
    When shipped from the factory, the MD-Series camera has two cables that 
    extend through the base.
    • The teal cable is to be connected to the supplied 25-foot Ethernet cable using  the supplied RJ45 waterproof coupler.
    • The black cable is to be connected to the 25-foot coaxial cable using the  suppled F-type female-to-female connector.
    Caution:  During installation, ensure the cables exiting the bottom of the camera 
    are not in contact with sharp edges, do not bend at sharp angles, and are not 
    pinched between the bottom of the camera  and the mounting surface. Do not pull 
    on the cables with excessive force. 
    The complete installation of the MD-Ser ies camera follows a series of steps:
    1.Remove the camera dome so that the camera is accessible
    2.Attach the grounding strap and mount the camera in the chosen location 
    3.Route the camera cables without tighteni ng the cable glands in the base. This 
    can be done with the connections ou tside the camera dome (simpler 
    approach) or inside the dome. The  MD-Series ICD contains a drawing 
    representing the two approaches
    4.Complete the electrical connections using the supplied PoE injector and 
    observe the video on a monitor

     Installing MD-Series Systems
    5.Adjust the pan/tilt position of the camera if needed and tighten the cable 
    glands in the base
    6.Replace the camera dome
    Important : Use a thread-locking compound such  as Loctite 242 or equivalent with 
    all metal-to-metal threaded connections.
    Remove the Camera Unit Dome
    1.Place both thumbs on the ball front near th e top of the opening and grip firmly 
    around the dome 
    2.Push down on the ball front with both  thumbs while pulling up on the dome
    3.Once the dome is detached, gently slide it up and off the camera 
    Mount the Camera Unit
    The camera unit can be mounted from the bottom, which is the recommended 
    approach because it is the most straightforward. If necessary, it is possible to 
    mount it from above by drilling holes in  the base plate. Both approaches are 
    described in this section.
    Prior to cutting or drilling holes, determine  if any interior trim panels must be 
    removed in order to gain access to the mounting hardware, and remove them 
    ahead of time.
    Caution:  Please be aware of these cautions:
    • When installing the camera, do not tighten fasteners in the threaded holes so  far that they contact the bottom of the threaded hole. Maximum insertion 
    should not exceed 6 mm (0.24 in), and torque should not exceed 9.5 N·m 
    (7 lbf· ft).
    • The F-type connector terminating the video cable on the camera is not a  sealed connection; therefore, appropriate sealing steps are needed to protect 
    the connection and the camera.
    • Before drilling holes, ensure the steps out lined in the planning section (starting 
    on page 10) have been followed. For example,  it is important to test the unit at 
    the planned installation location, with the typical vessel electronics active, prior 
    to mounting the camera.
    Mounting the Camera from the Bottom
    1.Using the mounting templa te supplied with the camera (and part of the 
    MD-Series ICD) as a guide, mark the location of the holes for mounting the 
    camera. Also mark the location for the cable port holes.
    Make sure the template is oriented proper ly relative to the bow of the vessel. If 
    the template is printed, be sure it is printed to scale so the dimensions are 
    correct.  
    						
    							 Installing MD-Series Systems
    14432-0010-00-12 Rev 100 — MD-Series Installation Guide 
    2.Drill the 4 holes for the mounting studs using a 6.4-mm diameter drill. Also drill 
    the appropriate cable port holes. 
    3.After the holes are drilled in the mounting surface, install  the four threaded 
    studs into the base of the camera with thread-locking compound. 
    4.Install the rubber O-ring in the groove in the base of the camera. 
    5.Pull the supplied grounding cable up through the cable access port and attach 
    it to the grounding stud on the base of the camera using a user- supplied ring 
    terminal.
    6.The next step depends on whether the  cables are connected externally or 
    internally:
    External Connection : Thread the video and Ethernet cables from the camera 
    through the cable port.
    Internal Connection:  Loosen the light grey capture nuts on both of the cable 
    glands in the base.Use a wr ench if they are tight. Pull the rubber glands and 
    clamping claws out of the threaded counter bores. Pull both cables completely 
    up through the base. Slip the rubber gland, clamping claw and capture nut off 
    each cable and set them aside. 
    7.Place the camera on the mounting surface so the threaded studs extend 
    through the drilled holes. 
    8.Secure the camera body to the mounting surface with the supplied nuts and 
    washers.

    Note:As needed, the threaded studs can be replaced with studs of a different 
    length or cut to a shorter length.
    Continue with “Route Camera Cables” on page 16.
    Mounting the Camera from the Top
    1.Loosen the light grey capture nuts on  both of the cable glands in the base, 
    using a wrench to loosen them if necessary. Pull the rubber glands and 
    clamping claws out of the threaded counte r bores, leaving them on the cable. 
    Pull both cables completely up through the base. (See the picture for step 6. in 
    the previous section.) 
    2.Using a 10-mm wrench, comp letely loosen the self-locking M6 bolt in the 
    center of the camera bracket in order to detach the base from the rest of the 
    camera assembly. 
    Make sure to place the bolt, washer, and thrust washer in a safe place for 
    reuse once the base is properly mounted.
    Caution : Do not detach the grounding c able since doing so will adversely 
    affect its seal. 
    3.Use the pilot locations in the base to  drill clearance holes for the 4 required 
    mounting fasteners. The ex act fasteners to use will vary depending on the 
    mounting surface. Maximum major diameter is 6.5 mm. Maximum head 
    diameter is 13 mm.

    Ensure that the size of the clearance holes accommodates the tolerance 
    associated with hand drilling, bolt patterns, and fastener  tolerances. 
    4.Using the mounting template supplied with the camera (and part of the 
    MD-Series ICD) as a guide, mark the location of the holes for mounting the 
    camera. The base itself can also be used as a guide. 
    Make sure the template is oriented properly  relative to the bow of the vessel. If 
    the template is printed, be sure it is printed to scale so the dimensions are 
    correct. 
    5.In addition to the four  mounting holes, drill the appropriate cable port holes 
    using the template as a guide. 
    6.Install the rubber O-ring in the base of the camera. 
    7.After the holes are drilled in the mounting surface, secure  the base to the 
    mounting surface with the required fasteners. Seal around fastener heads 
    using marine grade sealant (3M 4200 or equivalent).
    8.Using the M6 bolt, washer, and thrust  washer, reattach the camera to the 
    base.
    9.If connecting cables externally, rethread the video and Ethernet cables 
    through the counter bores and through the cable port, making sure the rubber 
    cable gland and clamping claw fit properly. 
    If connecting cables internally, leave the  cables as they are, refer to “Connect 
    Cables Internally” on page 19 and skip the next step. 
    10.Loosely tighten the light grey capture nuts at the base. Make sure to support 
    the cable so it is perpendicular to  the base. The nuts will be tightened 
    completely after any needed mechanical adjustments are made to the camera 
    pan and tilt (see page 24). 
    Route Camera Cables
    There are two options for routing the camera cables:
    • The simplest and most straightforward is  to route the cables through the two 
    cable glands in the base and connect the camera cables externally to the 
    extended 25-foot cables. In this  case the connections are visible.
    • Optionally make the connections withi n the camera by routing the longer 
    cables through the two base cable glands. In this case the connections are 
    hidden inside the dome cover.
    Caution:  It is recommended that any built-up  triboelectric charge on the Ethernet 
    cable be discharged  before connecting it to the camera. This can be 
    accomplished simply by pressing an ungl oved finger across the Ethernet RJ45 
    coupler of the cable for a few seconds. 
    						
    							432-0010-00-12 Rev 100 — MD-Series Installation Guide 17
     Installing MD-Series Systems
    Connect Cables Externally
    Leave the cables as installed from the factory and make connections outside the 
    camera unit, as shown in this diagram. This is the simplest way to install the 
    camera and is the recommended approach.
    Step 1 : Connect the Ethernet Cables (Teal and Grey)
    In this step, connect the camera’s Ethern et cable to one end of the supplied RJ45 
    coupler. Then connect the supplied 25-foot Ethernet cable to the other end. 
    The two ends of the RJ45 coupler are different, but if using the supplied cable, 
    connect either of the cables to either  ends. The complete coupler is shown below 
    on the left. On the right, the coupler is fully disassembled showing all 
    components. 
    Caution:  The Ethernet clamping claw is delicate; treat it gently so that no prongs 
    are broken 
    1.Connect the teal Ethernet cable to  the RJ45 coupler using these steps:
    a.Remove the dark grey capture nut, gland, and claw from one end of the 
    RJ45 coupler. 
    b.Thread the teal cable through the dark grey capture nut, followed by the 
    dark grey claw. Then wrap the cable gland around the cable. Seat the 
    clamping claw over the gland.
    c.Insert the end of the cable into the end receptor in the coupler. This picture 
    shows the sequence of pieces on the cable. 
    d.Bring the capture nut up to the coupler and tighten it.
    2.Then connect the 25-foot Ethernet cabl e to the other end of RJ45 coupler:

    a.Remove the rubber boot from the end of the Ethernet cable using a cutter. 
    It will not seal correctly with the rubber boot in place.
    Caution: Be careful not to cut any part  of the Ethernet cable when 
    removing the rubber boot to ensure the enclosure seal is not 
    compromised.
    b.Remove the dark grey capture nut, clamping claw, and gland from the 
    other end of the RJ45 coupler. 
    c.Thread the 25-foot Ethernet cable through dark grey capture nut, followed 
    by the dark grey claw. Then wrap the cable gland around the cable. Seat 
    the clamping claw over the gland.
    d.Insert the end of the 25-foot Ethernet  cable into the receptor in the coupler 
    until it snaps into place.
    Caution : Be careful to minimize any tw isting in the cable to prevent 
    communication failure. 
    e.Bring the capture nut up to the coupler and tighten it.
    f.Pull down on the cable at the camera base to reduce slack for dome 
    clearance. 
    g.Loosely tighten the light grey capture nut at the base. Make sure to support 
    the cable so it is perp endicular to the base.  The nut will be tightened 
    completely after any needed mechanical adjustments are made to the 
    camera pan and tilt (see page 24). If no further adjustments are needed, 
    hand tighten the capture nut and then make an additional 1/4 turn with a 
    wrench.
    Step 2 : Connect the Video Cables (Black)
    Connect the video cable from the camera  to the 25-foot video cable using the 
    supplied female-to-female connector. Then seal the connection with marine 
    grade sealing tape and electrical tape. 
    1.Thread the female-to-female connector into the end of the camera’s video 
    cable with a 7/16 inch wrench.
     
    Important : Be sure to apply thread locker to the F-type connectors.
    2.Attach the 25-foot coaxial cable to the other end of the connector after 
    applying thread locker so that it looks like the picture below.
