FIXING ELEMENTS
With monitor ST7100 the video connection
can be made with 75 Ohm coaxial cable or
twisted pair. The choice between the two sys-
tems depends on the correct selection of video
distributor and camera. The number of wires
and possible installations does not change.
Do not forget to position jumper J2 cor-
rectly and use the proper input terminals
on bracket WB7100.
