 Installing M-Series Systems
Camera Video Options
The M-Series gimbal assembly has either one or two video cables:
• The cable labeled IR is for the composite—also known as analog—video 
signal from the thermal (infrared) camera. This is the only cable on single 
payload cameras.
• On dual payload models, the cable labeled VIS/IR is for video from either the 
thermal camera or the DLTV camera. You use the JCU to determine which 
output displays.

When selecting a mounting location for the M-Series, consider cable lengths and 
cable routing. Ensure the cables are long enough, given the proposed mounting 
locations and cable routing requirements, and route the cables before you install 
the components. 
If you are using one of the top-down installation kits, the riser or plate should be 
used as a template for the location of the drill holes and cable access hole....

Physical Installation
Use a thread-locking compound such as Loctite 242 or equivalent with all metal-
to-metal threaded connections.
Installing the Camera Unit
With the exception of theM-618CS model, which must be installed in the ball-up 
orientation, the M-Series camera can be mounted in an upright or upside down 
position. Two O-rings are provided for use during the camera installation. You 
should choose the one most...

As an alternative to the mounting O-ring, you can use a marine-grade sealant 
such as 3M 5200 or the equivalent.
Mounting Upright
Caution: The cable connectors terminating the pigtail cables on the camera are 
not sealed connectors; therefore, appropriate sealing steps are needed to protect 
the connections and the camera.
Caution: Before drilling holes, ensure you have first followed the steps outlined 
in the planning...

Caution: An installation template is provided in the JCU ICD. If you print the 
template from the PDF file, ensure that it was printed to the correct scale by 
checking the dimensions prior to cutting any holes.
Standard JCU Mounting Instructions
1.Using the JCU template supplied as a guide in Doc. # 500-0385-19, mark the

rear of the mounting surface and allows the clamp to contact thinner panel 
surfaces while still allowing for proper compression of the JCU mounting gasket 
to form a watertight seal.
Electrical Connections
Watertight connectors/enclosures should be used on each of the electrical 
connections. Table 1.1 shows the connections for the cables attached to the 
camera.

Proper Grounding
Caution: Ensure the camera is properly grounded. Following best grounding 
practices, the camera chassis ground should use the lowest resistance path 
possible. 
The green wire in the camera cable can be used to provide chassis ground for 
cable lengths under 2 m (6 ft). For longer cabling, the camera must be connected 
to a vessel ground using a low-resistance grounding strap connected directly to 
one...

Warning: Use of insufficient wire gauge can result in fire. Suggested gauge 
depends on supply voltage shown. For lower supply voltages, lower gauge wire 
must be used.
Video Connections
The video cables from the camera are terminated with F-type male connectors. 
Video cables of various lengths with F-type female connectors at one end and 
BNC-connectors at the other end are available from FLIR. The video cable used...

suggests that you clean the lens when image quality degradation is noticed or 
excessive contaminant build-up is seen on the lens. 
Rinse the camera housing and optics with low pressure fresh water to remove 
any salt deposits and to keep it clean. If the front window of the...
