Use only industry standard Category-5 Enhanced (CAT5e) cable to operate the
CAT5•8000 system.
Local video outputs are provided on the CAT5•8000 Sender unit for monitoring
purposes. Any monitor connected to a local video output port (Monitor Out 1, 2, or 3)
must be able to display a matching resolution with its corresponding remote display
on the CAT5•8000 Receiver unit.
The CA T5•8000 system does not pass EDID (Extended Display Identifi cation Data)
from the extended monitors back to the source. EDID is not necessary to output
standard VESA VGA video from a computer. In situations where non-VESA VGA
resolutions are required, a DVI Detective (EDID storage device), part #EXT-DVIEDID, will be required for each non-VESA resolution monitor connected to the
CAT5•8000.
The CAT5•8000 units are housed in a metal box for better RF shielding.
The CAT5•8000 Sender unit can be powered from the USB cable without the ex-
ternal power supply.

The CAT5•8000 sends three analog monitors, one USB 1.1 equipped keyboard/
mouse, one analog audio signal, and one RS-232 device (like a touchscreen) up
to 330 feet from the computer using multiple CAT5e cables. It’s designed for those
situations where multiple extended video screens need to be relocated to a distant
location. USB 1.1 control, audio and RS-232 support is provided to enable remote
operation.
How It Works
The CAT5•8000 uses a sender and receiver methodology to transmit signals from
the computer to the workstation. The sender connects to the computer using the
cables provided. The receiver connects to the three monitors, one RS232 serial
device, and one analog audio device up to 330 feet away. Multiple CAT5e extension
cables (up to 4 for the CAT5-8000), user provided, connect the sender to the
receiver units. Both the sender and the receiver are powered separately using the
provided power supplies. When connected and operational, the units extend all
signals effi ciently and reliably.

CONNECTING THE CAT5•8000
5
Connect the computer’s VGA output ports (supports up to three displays) to the
CAT5•8000 Sender unit using the supplied VGA male to female cables.
Connect the computer’s stereo audio mini-jack output to the CAT5•8000 Sender
unit using the supplied stereo audio mini-jack cable.
Connect the USB from the computer to the CAT5•8000 Sender unit using the
supplied USB A to B cable. The A side of the USB cable needs to be connected
to a free USB A port on the computer, while the B side needs to be connected
to the B connector on the CAT5•8000 Sender unit.
Optionally, you can connect the RS-232 to the CAT5•8000 Sender unit using a
user supplied RS-232 cable. This cable must be a straight-through patch cable.
A null-modem cable will not work for this application.
Connect the CAT5•8000 Sender unit to the CAT5•8000 Receiver unit using four
user supplied CAT5e cables. Termination of the cabling must adhere to the TIA/
EIA-568-B standard. See page 9 for more details.
Connect the displays to the CAT5•8000 Receiver using user supplied VGA
cables. Up to 4 displays can be connected to the CAT5•8000 Receiver. Video
Out 1 and 2 on the CAT5•8000 Receiver correspond to Video In 1 and 2 on
the CAT5•8000 Sender. Both VGA output ports labeled as Video Out 3 on the
CAT5•8000 Receiver corresponds to Video In 3 on the CAT5•8000 Sender. The
second Video Out 3 VGA output port is a mirrored output for Video In 3 and is
for the connection of an additional display.
Connect amplifi ed speakers to the CAT5•8000 Receiver unit using a user
supplied stereo audio mini-jack cable.
Connect USB peripherals to the CAT5•8000 Receiver unit using user/device
supplied USB cables. The connection to the CAT5•8000 Receiver unit must be
USB A type.
Optionally, connect a RS-232 peripheral to the CAT5•8000 Receiver unit with a
user supplied RS-232 cable.
Plug both supplied 5V DC power supplies into the CAT5•8000 Sender and
Receiver units.
Power all monitors fi rst, and then power on the computer.
Note: There is a second stereo audio mini-jack input and output for an
additional audio signal to be transmitted to the remote location. It is not
necessary to connect these audio ports for the CAT5•8000 to function properly.

OPERATING AND TUNING THE CAT5•8000
6
Once all connection have been made and an image appears on the remote
monitors, the images may need to be tuned to perfect the video signal. The
CAT5•8000 has been engineered to provide exceptional video quality and user
functionality, but the variance in cable length and quality is a variable that can create
color separation and ghosting. These artifacts can be eliminated by fi ne tuning the
CAT5•8000. Please refer to the section below if the CAT5•8000 exhibits any video
issues.
Brightness Adjustment
The CAT5•8000 Receiver has three brightness adjustment trim pots on its front
panel. If the resulting image is either too bright or too dim, use a small fl athead
device to turn each trim pot in either a clock-wise or counter-clock-wise direction.
Turn the trim pot in small increments to either brighten or dim the image. Once a
satisfactory brightness level has been achieved, remove the fl athead device.
Jumper Settings
Variances in CAT5e cable skew and quality may cause the individual colors in the
VGA signal (red, green, and blue) to arrive at the CAT5•8000 Receiver at slightly
different times. These delays can cause the colors in the image to be offset, cause
the video to appear slightly out of focus, and ultimately degrade the video image.
Inside the CAT5•8000 Receiver unit are sets of jumper pins that will allow the user to
fi ne tune each color and compensate for these delays in the CAT5e cable. Because
there are multiple displays that are being sent from the CAT5•8000 Sender to the
Receiver, a separate bank of jumper pins are provided for each display. Because
this operation requires the unit to be partially disassembled, please follow these
steps ONLY if there are issue in the video quality.
Open the CAT5•8000 Receiver by removing all screws on the underside and
sides of the unit.
Remove the hex nuts associated with all HD-15 (VGA) and RS-232 heads on
the rear panel of the CAT5•8000 Receiver unit.
Carefully slide the unit apart to reveal the circuit board of the CAT5•8000
Receiver unit.
Locate the jumper pin banks using the diagram on the next page.
First, focus the image by setting the jumper pins according to the distance of
CAT5e cabling using the table on the next page. Move the red, green, and blue
jumpers together for each of the video outputs.
Fine adjustment to each color can now be done to individual colors based on
what is viewed on screen. Move the jumper either up or down on each color to
adjust the delay until the picture no longer appears smeared.
