Environmental Information
The equipment that you bought has required the extraction and use of natural
resources for its production. It may contain hazardous substances that could
impact health and the environment.
In order to avoid the dissemination of those substances in our environment and
to diminish the pressure on the natural resources, we encourage you to use the

1. Installation and Getting Started
1. Installation and Getting Started
This document describes how to use the Epiphan VGA Splitter
device to split a single VGA signal between two VGA display,
capture, or recording devices. The Epiphan VGA Splitter is an
active splitter that takes a single VGA input and provides two
VGA outputs:
• A fault tolerant VGA output
• An amplified VGA output
The fault tolerant VGA output provides a direct connection to the
original VGA output and is delivered by the Epiphan VGA
Splitter without any changes to the VGA signal. If the Epiphan
VGA Splitter loses power, the fault tolerant VGA signal will be
maintained. The quality of the amplified VGA output is also the
same as the original VGA signal. It is a copy of the original VGA
signal that is then amplified by the Epiphan VGA Splitter. The
amplified signal is lost if power is disconnected from the VGA
Splitter device.

Hardware Features
The following table describes VGA Splitter hardware features.
Power Connect the AC power adapter to the VGA
Splitter power connector and to a power
outlet.
VGA IN Connect the VGA source to the VGA IN port
using a standard VGA cable.
VGA OUT (fault

VGA OUT Connect a second VGA monitor or projector
Connect a VGA monitor or projector to view
the video signal received at the VGA IN port.
The VGA OUT (fault tolerant) port connects
directly to the VGA IN port and will continue
to function if the VGA Splitter loses power
because of a power interruption or because
the AC power adapter is disconnected.
to split the video signal received at the VGA
IN port. The VGA signal to the VGA OUT
port is amplified by the VGA Splitter to be as
high quality as the signal received at the VGA
IN port. The signal at the VGA OUT port will
be lost of the VGA Splitter loses power.

Connecting and Powering on the VGA Splitter
This section describes how to connect a VGA Splitter to a VGA
source and to a VGA monitor and VGA Frame Grabber (Figure 1).
The Frame Grabber is connected to the fault tolerant VGA OUT
port because the primary application is image capture using the
Frame Grabber.

User Guide Page 5
To connect the VGA Splitter
1 Use a VGA cable to connect the VGA source to the VGA
Splitter VGA IN port.
2 Use another VGA cable to connect the VGA Frame Grabber
(for example, a VGA2USB device) to the VGA Splitter VGA
OUT (fault tolerant) port.
3 Connect a VGA display device (for example a VGA monitor)
to the VGA Splitter VGA OUT port.
1. Installation and Getting Started Troubleshooting
4 Connect the power cable to the VGA Splitter power port.
As it receives VGA signals from the VGA source, the VGA
Splitter splits the signal, sending the original signal to the
Frame Grabber and a high-quality copy of the signal to the
VGA display device.
Troubleshooting
If the VGA OUT port is not receiving a VGA signal but the VGA
OUT (fault tolerant) port is, make sure the VGA Splitter is
receiving power.
If neither of the VGA OUT ports are receiving a VGA signal,
check all connections to the VGA Splitter. You should also verify
that the VGA source is operating correctly and that the VGA
display devices are receiving power.
