Problem

Wavy or ghost image if connected to image processor (e.g., multiplexer or DVR), but not if directly to monitor?

Image background flutters between dark and light?

Image is weak or faded?

No image?

Possible Cause

a. Strong electromagnetic

interference. b. Split pairs. c. Crimped cable.

Interference from external power source.

a. Exceeded recommended balun

separation. b. Using lower-grade cable than

recommended.

a. Power is off. b. Cable is incorrectly

connected/crimped. c. Cable was accidentally cut. d. Defective video source. e. Defective video destination.

Possible Solution

a. Move the cable away from possible sources of

interference.

b. Ensure same twisted pair connects to balun at both ends

of cable.

c. Replace cable with new cable.

Remove power source, or adjust monitor's brightness and contrast.

a. Reduce cable length. b.

Replace with a higher-grade cable. CAT 5 cable meets specifications in allows longer range.

a. Check the power supplies of all devices connected to the

cable.

b. Double-check that the cable was connected and crimped

properly. c. Run a continuity test on all wires in the cable. d. Replace the unit with a new unit. e. Replace the unit with a new unit.

Passive VGA Baluns

EVT-SBP-GQ

VGA Balun Set

EVT-TBP-GCNQ*

TX / PC / Source Side

EVT-RBP-GNCQ*

RX / Monitor / Destination Side

Range: Up to 450’ (137m) over STP cable

*Note: SECO-LARM Passive VGA Baluns are sold as a set only.

The model numbers EVT-TBP-GCNQ (transmitter / PC / source side) and EVT-RBP-GNCQ (receiver / monitor / destination side) are provided for identification purposes only.

What it is:

VGA baluns allow extension of the range between CCTV video sources such as PCs, digital video recorders, or video splitters, and CCTV video destinations such as CRT / LCD monitors or video projectors. The range is up to 450 feet (137m). The connection is via low-cost Cat 5 or Cat 5E shielded twisted-pair (STP) cable with shielded RJ-45 connectors. This allows the monitor or projector to be easily installed on a security professional's desk while the video devices are locked securely in a separate room.

Features:

Note: For some CRT monitors, a gender changer may be required. The CA-1D1DQ is designed to connect the

EVT-RBP-GNCQ to the CRT monitor cable.

●

Passive operation -- No power required.

●

Sends a VGA video signal from a VGA source (personal computer, digital video recorder, video splitter, or other video source) to a VGA destination (CRT monitor, LCD monitor, or VGA projector).

●

Uses Cat 5 or Cat 5E shielded twisted pair (STP) cable instead of heavier, more expensive VGA cables.

●

Works at the following resolutions and maximum distances:

640x480 (VGA) 450ft (137m) 800x600 (SVGA) 350ft (107m) 1024x768 (XGA) 250ft (76m) 1280x1024 (SXGA) 200ft (61m)

●

Small size, only 21/8" x 13/16" x 1" (55 x 30 x 26 mm) with a 6" (152mm) pigtail for the VGA connector.

●

The EVT-SBP-GQ is sold as a set - one for the source side, one for the monitor side.

CA-1D1DQ Gender Changer.

Allows EVT-RBP-GNCQ to connect to certain CRT monitor cables. Product sold separately

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.
