Installation

1. Locate TwinSplit E.D. within 6 feet of the computer.

2. Connect the 6 ft. VGA jumper cable supplied from the VGA output of the

computer to the connector marked VGA.

3. Connect the VGA compatible monitors to the OUTPUT on the rear of

TwinSplit E.D. Monitor extension cables (CAB-27) may be used to extend

the distance up to 700 feet, according to the table below.

4. Plug the 9 Vdc wall power transformer supplied into the jack on the rear of

TwinSplit E.D.

5. Plug the power transformer into an AC power wall outlet. The front panel

LED should glow red, indicating the unit is properly powered.

6. Turn on the computer and the monitor(s). The monitor(s) will now display

the computer’s output.

7. The front panel knobs are used to

adjust the gain and peaking of the

amplifiers of the TwinSplit E.D. to

compensate for the long extension

cable being used. These knobs have

6 positions from SHORT to LONG

and correspond to cable lengths for

standard VGA up to 480 lines

approximately as shown.

Note: For SUPER-VGA modes operating at 600 lines, the maximum

recommended length is 600 feet. For SUPER-VGA modes operating at 768

lines, the maximum recommended length is 500 feet.

8. As shipped, TwinSplit E.D. is internally jumpered to support a standard color

VGA monitor. The

internal jumpers are

located on the jumper

block JP1 and may be

changed for different

monitor types as

shown.

TwinSplit E.D. requires no ongoing adjustments once it is installed. It is designed

to work continuously and can be placed “out of sight” if desired.

The design intention of the product is to provide a reliable means of extending

the viewing position of VGA monitors. This means compensating for the normal

signal losses which will occur when adding cable to a VGA monitor. This is

achieved through equalized amplification so that the signal at the remote end

matches closely to the signal as it left the VGA adapter. This ensures the truest

representation of the VGA image as it relates to detail and color fidelity. If

lengths of longer than 700 feet are necessary, consult Communications Specialties

for system design assistance.

Additionally, each monitor output is independently buffered. This ensures

isolation and proper signal levels regardless of the number of monitors used. The

splitters may be cascaded to achieve multiple outputs at different distances from

the computer. Communications Specialties can help with specific application

assistance.

Please note that the plug-in transformer will feel warm after the unit is on

for a period of time. This is normal as TwinSplit E.D. draws a significant amount

of power.
