Choosing the video connection with coaxial cable or twisted pair
With monitor ST7100 the video connection can be made either with 75
Ohm coaxial cable or twisted pair. The choice between the two systems
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 correctly and use the proper input
terminals of bracket WB7100.
