Introduction
Overview
ATEN VE814A is an HDBaseT Video Extender that is capable of sending
HDMI signals up to 100 m over a single Cat 5e/6/6a or ATEN 2L-2910 Cat 6
cable. Featuring dual synchronous outputs, the VE814A can transmit identical
outputs to two remote displays and one display at the local side. This
HDCP 2.2-compliant extender meets the HDMI Specification, including 3D,
Deep Color, the maximum data rate of 10.2 Gbps, and transmission of 4K
videos up to 100 m.
Supporting bi-directional RS-232 and full-range IR signaling pass-through, the
VE814A allows you to control an HDMI source device from the remote unit
(VE814AR) while granting access to the HDMI display device from the local
unit (VE814AT). In addition, it supports Long Reach Mode that extends HDMI
signals up to 150 m, 1080p, via a single Cat 5e/6 cable.
The VE814A is a powerful solution for where digital signage is required, such as
bars, educational spaces, and public transportation stations, allowing display of
identical contents at different spots.

Connecting the VE814A Unit
Follow the steps below to connect the VE814A to a source and other devices as
required.
1. Use an HDMI cable to connect the HDMI Out port on your source device to
the HDMI In port on the VE814AT.
2. Use an RJ-45 cable to connect the HDBaseT Out port on the VE814AT to
the HDBaseT In port on the VE814AR.
3. Depending on your preferred location of display, connect a display device
to the VE814AT or VE814AR using an HDMI cable.
Note: When displays are connected to the VE814A transmitter and
VE814A receiver, the VE814A system adopts the EDID values of the
display connected to the transmitter’s side.
4. Plug the Power Adapter Cables into the Power Jack on the VE814AT and
VE814AR.
5. (Optional) To send RS-232 serial commands, connect a computer or
control system to the RS-232 Port on the VE814AT or VE814AR.

Operation
Long Reach Mode
Long Reach Mode is a modulation that extends the transmission distance up to
150 m while compromising the maximum frame rate to 1080p, 60 Hz, 24 bpp.
To enable the Long Reach Mode, make sure to do the following:
Use a Cat 5e/6/6a or ATEN 2L-2910 cable to connect the VE814AT and the
VE814AR
Put the HDBaseT Long Reach Mode Switch to ON at either the VE814A
transmitter or the VE814A receiver.
Note: When enabled with Long Reach Mode, the VE814AT and VE814AR will
not be able to transmit 4K signals, in which case, the output display will
be blank.

Safety Instructions
General
This product is for indoor use only.
Read all of these instructions. Save them for future reference.
Follow all warnings and instructions marked on the device.
Do not place the device on any unstable surface (cart, stand, table, etc.). If
the device falls, serious damage will result.
Do not use the device near water.
Do not place the device near, or over, radiators or heat registers.
The device cabinet is provided with slots and openings to allow for
adequate ventilation. To ensure reliable operation, and to protect against
overheating, these openings must never be blocked or covered.
The device should never be placed on a soft surface (bed, sofa, rug, etc.) as
this will block its ventilation openings. Likewise, the device should not be
placed in a built in enclosure unless adequate ventilation has been provided.
Never spill liquid of any kind on the device.
Unplug the device from the wall outlet before cleaning. Do not use liquid or
aerosol cleaners. Use a damp cloth for cleaning.
The device should be operated from the type of power source indicated on
the marking label. If you are not sure of the type of power available, consult
your dealer or local power company.
The device is designed for IT power distribution systems with 230V phase-
to-phase voltage.
To prevent damage to your installation it is important that all devices are
properly grounded.
The device is equipped with a 3-wire grounding type plug. This is a safety
feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not attempt to defeat the
purpose of the grounding-type plug. Always follow your local/national wiring
codes.
Appendix
16
Do not allow anything to rest on the power cord or cables. Route the power
cord and cables so that they cannot be stepped on or tripped over.
If an extension cord is used with this device make sure that the total of the
ampere ratings of all products used on this cord does not exceed the
extension cord ampere rating. Make sure that the total of all products
plugged into the wall outlet does not exceed 15 amperes.
To help protect your system from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
Position system cables and power cables carefully; Be sure that nothing
rests on any cables.
Never push objects of any kind into or through cabinet slots. They may
touch dangerous voltage points or short out parts resulting in a risk of fire or
electrical shock.
Do not attempt to service the device yourself. Refer all servicing to qualified
service personnel.
If the following conditions occur, unplug the device from the wall outlet and
bring it to qualified service personnel for repair.
The power cord or plug has become damaged or frayed.
Liquid has been spilled into the device.
The device has been exposed to rain or water.
The device has been dropped, or the cabinet has been damaged.
The device exhibits a distinct change in performance, indicating a need
for service.

Rack Mounting
Before working on the rack, make sure that the stabilizers are secured to
the rack, extended to the floor, and that the full weight of the rack rests on
the floor. Install front and side stabilizers on a single rack or front stabilizers
for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the
rack first.
Make sure that the rack is level and stable before extending a device from
the rack.
Use caution when pressing the device rail release latches and sliding a
device into or out of a rack; the slide rails can pinch your fingers.
After a device is inserted into the rack, carefully extend the rail into a
locking position, and then slide the device into the rack.
Do not overload the AC supply branch circuit that provides power to the
rack. The total rack load should not exceed 80 percent of the branch circuit
rating.
Make sure that all equipment used on the rack – including power strips and
other electrical connectors – is properly grounded.
Ensure that proper airflow is provided to devices in the rack.
Ensure that the operating ambient temperature of the rack environment
does not exceed the maximum ambient temperature specified for the
equipment by the manufacturer.
Do not step on or stand on any device when servicing other devices in a
rack.
