Installation
TM-250 Miniature CCD Camera
2.2.3
Attaching the Video Output
Most users utilize the BNC connector for video output from the camera. Connect the output from the
camera to the input of your monitor, VCR, or switching device. The input of the monitor should be
balanced for 75
Ω
termination. Standard RG-59 type coaxial cable should carry a full video signal for up
to 500 feet.
To output the video and input the power and sync to a camera over a single cable, use the PULNiX
multi-conductor cables, such as the 12P-02S, etc. The mini coaxial leads in PULNiX multi-conductor
cables are designed for short runs of no longer than 100 feet.
Note:
Make sure that no extraneous wires are visible which could cause a short.
2.2.4
Attaching the Camera Lens
The TM-250 camera accepts 1/2" or larger format size C-mount lenses. To attach the C-mount lens to
the camera, carefully engage the threads and rotate the lens clockwise until it firmly seats on the
mounting ring. Do not force the lens if it does not seat properly. Please note that some lenses with
extremely long flangebacks may exceed the mounting depth of the camera.
2.2.5
Auto-Iris Lens Setup
Auto-iris lenses with full video input can be used with the PULNiX TM-250, although this camera
model does not come equipped with auto-iris output.
Note:
Make sure that the power is removed from the camera before connecting or disconnecting
the auto-iris lens. There is a small chance that the auto-iris lens could be damaged by
plugging or unplugging it while the camera is powered up.
Power down the camera before installing the auto-iris lens. To install the auto-iris lens in a PULNiX
camera without an auto-iris output, wire the signal (video) on the lens into the terminal 1 Vp-p video
output on the camera.
Point the camera at a light area and then quickly towards a darker area. If everything is working
properly, the iris should adjust for the light change.
2.2.6
Monitor Display Mode
For monitoring real-time video, connect the video output to a video monitor or other device.
