Note:
The maximum cable length between the camera and the injector is limited
to 100m per the PoE IEEE802.3af specification.
Installing a Joystick Control Unit (JCU)
If an optional JCU is used for controlling camera settings, mount it in a
convenient area that is close to the monitor being used to display the MD-Series
video output. Make sure there is sufficient clearance for the cable under the JCU
(refer to the MD-Series ICD for dimensions). The magnetic compass safe
distance for the JCU is 55 cm (21.7 in).
The JCU can be mounted to the dash (or other surface) in any orientation, using
four captive mounting screws that hold panel mounting clamps. When the
mounting screws are tightened, the panel mounting clamps rotate and extend
away from the JCU at a right angle, and come into contact with the mounting
surface. The JCU can be mounted to dash thicknesses ranging from 0.16 – 4.45
cm (0.063 – 1.750 in). A trim bezel snaps on top of the JCU to cover the
mounting screws.
JCU Connection to Camera
The JCU is a Power over Ethernet (PoE) device and cannot be connected to the
camera directly. Installation of a JCU will require an additional PoE injector.
Alternatively, the camera and the JCU can be connected together via an Ethernet
switch; this type of configuration allows more than one JCU or camera to be
used. The JCU draws its power through the Ethernet connection, so a PoE
injector or PoE switch is required. The JCU could also be powered using an
additional PoE injector coupled with a non-PoE switch.
Ferrite Clamp
A clamp-on ferrite, consisting of a ferrous ceramic core, is attached to the JCU
cable close to the PoE injector to reduce any high-frequency noise that might
interfere with communication.
Open the ferrite, lay the cable into the inner groove, and snap the cover shut. The
ferrite should fit snugly over the cable, but if sliding is an issue, add a zip tie on
either side of the ferrite to limit movement.
Prior to Cutting Hole
To ensure a proper seal around the JCU, the supplied gasket must be applied to
the JCU and the cutout opening for the JCU should precisely match the template.
If the cutout opening is too large, the gasket around the JCU may not cover the
opening adequately.
JCU Installation Steps
The cable gland seal is designed for use with double-shielded category 5
Ethernet cable. To ensure a good seal and to maintain compliance with EMI
ratings, a double-shielded cable is required.
