Description
The Model 1800-RA is a VGA (RGBHV) video splitter that employs the latest technologies in high-resolution
video distribution. The rack-mountable unit provides one VGA input and 18 VGA outputs. 16 of the 18 outputs can
be boosted beyond the normal signal levels in order to drive long cable up to several hundred feet.
The device is rugged, rack-mountable, low power, and highly reliable. The can reproduce a sharp and crisp image at
any resolution up to 1600 x 1200.
The Splitter has a built-in universal power supply. And comes with a 6 ft multi-coaxial cable for connection to the
PC’s video.

• Rugged, Reliable, Economical
• No software required
• Drives cables to 300 ft or more
• Easily expand outputs by daisy-chaining
Setup
Your package should include a six foot VGA-Type video cable, a power cable, and the Video Splitter unit itself.
Please take inventory of all items received and ensure that you have the above items.
Locate the Video output connector on the Computer. This connector is generally a HD15 female with three rows of
contacts. Using the cable supplied, connect the input of the Splitter to the computer.
Connect the monitors directly to the outputs of the Splitter, or use high-quality extension cables to remotely locate
the monitors. Connect the AC power to the Splitter.
If you are using long video cables (greater than 25 feet) on the output of the splitter, it is best to ensure that the cable
is connected to a monitor (which properly terminates the signals), otherwise disconnect the cable from the Splitter.
Driving Long Cables
The outputs numbered 1 to 16 can drive cables longer than 100 feet. These ouputs are devided in to 4 groups of 4
channels (i.e. group 1 is comprised of Out_1 through Out_4, group 2 is comprised of Out_5 through Out_8, etc.).
Each group of 4 has a switch that sets its output drive capability to normal or boosted. If the cable connected to the
output is less than 100 feet set the switch to the left, otherwise set it to the right for boosed output.
Outputs 17 and 18 are always normal and cannot be boosted, they are good for monitors that are located upto 100 or
150 feet from the unit.
