All Monitor BUS lines must be terminated with an End of Line resistor on the last

monitor in the run. This is built into each monitor and can be installed by putting a jumper

connector on J1. The location of this jumper is illustrated on Page 12. If a BUS is not

terminated properly, the electronic characteristics of the line will change resulting in signal

degradation and poor video quality.

Using EVB33 Distribution Units with BUS risers:

Always try to avoid branching or “T-Tapping” to connect monitors from a riser as this

will cause changes in the riser electronic characteristics which may cause signal

degradation and poor video quality. However, when it is necessary to “T-Tap” a line from

a BUS line, there are two important things to remember.

1. Use an EVB33 for each “T-Tap” to help minimize issues with signal propagation. This

can be done in an “in-line” method alternating polarity of the monitors, (maximum of 6

monitors or 8-10 monitors on the total riser) or in a “star” pattern with up to three monitors

on their own “sub” risers.

2. Always use the End of Line jumper at the physical end of a riser line.

Both of these items are illustrated below.
