ENFORCER VGA BALUN

Installation:

1.Make sure to use shielded twisted pair (STP) cable terminated with shielded RJ-45 connectors. This will ensure good signal levels between the various video components.

2.Since Cat 5 does not have sufficient lines to support VGA handshaking and control signals, it will be necessary to configure the monitor settings before installing the baluns:

To configure the monitor, connect it to the PC (or other video source), using a standard VGA cable. Configure the monitor (resolution, color depth, refresh rate, and so on) to the desired settings. Also, set the contrast and brightness levels to maximum. These will be adjusted after the VGA baluns are connected.

3.Turn off the power to the PC and monitor and disconnect the VGA cable.

4.Connect the PC side balun (EVT-TBP-GCNQ) to the VGA connector of the PC or video source.

5.Connect the monitor end balun (EVT-RBP-GNCQ) to the VGA display screen or video destination.

Note: For CRT monitors, a gender changer may be required. The CA-1D1DQ is designed to connect the EVT-RBP-GNCQ to the CRT monitor cable.

6.Connect a shielded Cat 5 cable to the RJ-45 jacks on each of the baluns.

7.Make sure to tighten all the connections.

8.Turn on the PC and monitor.

9.Adjust the monitor contrast and brightness settings for comfortable viewing.
