Important Safety Instructions
1. READ these instructions.
2. KEEP these instructions.
3. HEED all warnings.
4. FOLLOW all instructions.
5. DO NOT use this apparatus near water.
6. CLEAN ONLY with dry cloth.
7. DO NOT block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including ampliers) that
produce heat.
9. DO NOT defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding prong. The wider blade or the third prong are provided for your
safety. If the provided plug does not t into your outlet, consult an electrician for replacement of the obsolete outlet.
10. PROTECT the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
11. ONLY USE attachments/accessories specied by the manufacturer.
12. USE ONLY with a cart, stand, tripod, bracket, or table specied by the manufacturer, or sold with the apparatus. When a cart is
used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. UNPLUG this apparatus during lightning storms or when unused for long periods of time.
14. REFER all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in any way, such as
power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped.
15. DO NOT expose this apparatus to dripping or splashing and ensure that no objects lled with liquids, such as vases, are placed on
the apparatus.
16. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug from the AC receptacle.
17. Where the mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily
operable.
18. DO NOT overload wall outlets or extension cords beyond their rated capacity as this can cause electric shock or re.
The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying the product.
The lightning ash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure that may be of sucient magnitude to constitute a risk of electrical shock to
persons.
ESD Warning: The icon to the left indicates text regarding potential danger associated with the discharge of static electricity from an
outside source (such as human hands) into an integrated circuit, often resulting in damage to the circuit.
WARNING: To reduce the risk of re or electrical shock, do not expose this apparatus to rain or moisture.
WARNING: No naked ame sources - such as candles - should be placed on the product.
WARNING: Equipment shall be connected to a MAINS socket outlet with a protective earthing connection.
WARNING: To reduce the risk of electric shock, grounding of the center pin of this plug must be maintained.

User Manual - VPX-1401 3
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before
touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be
followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive
smocks, and conductive work mats are specically designed for this purpose. These items should not be manufactured
locally, since they are generally composed of highly resistive conductive materials to safely drain static discharges, with-
out increasing an electrocution risk in the event of an accident.
Anyone performing eld maintenance on AMX equipment should use an appropriate ESD eld service kit complete with at
least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another ground cord.
WARNING: Do Not Open! Risk of Electrical Shock. Voltages in this equipment
are hazardous to life. No user-serviceable parts inside. Refer all servicing to
qualied service personnel.
Place the equipment near a main power supply outlet and make sure that you
can easily access the power breaker switch.
ESD WARNING
WARNING: This product is intended to be operated ONLY from the voltages listed on the back panel or the recommended,
or included, power supply of the product. Operation from other voltages other than those indicated may cause irre-
versible damage to the product and void the products warranty. The use of AC Plug Adapters is cautioned because it
can allow the product to be plugged into voltages in which the product was not designed to operate. If the product is
equipped with a detachable power cord, use only the type provided with your product or by your local distributor and/or
retailer. If you are unsure of the correct operational voltage, please contact your local distributor and/or retailer.
FCC AND CANADA EMC COMPLIANCE INFORMATION:
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment o and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

User Manual - VPX-1401 6
Overview
VPX-1401 is an advanced presentation switcher, allowing switching among four inputs and distribution to two outputs. It oers
one VGA input with one balanced analog audio embedded, three HDMI inputs, one HDMI output to a local display, plus one
balanced de-embedded analog audio output and one HDBaseT mirrored output to a remote display via a Cat X cable.
The VPX-1401 has one built-in scaler which supports up to 4K@60Hz 4:4:4 8bit. The video stream goes through the scaler rst
before distributing to two outputs. The scaler output can be set to xed resolution or auto scaling. When set to auto scaling, the
scaler analyzes the EDIDs of two connected displays and outputs optimum resolution for both displays.
The VPX-1401 can be set to auto switching or manual switching. The VPX-1401 can be controlled by front panel buttons, LAN
control with NetLinx Studio, Telnet API and Web GUI.
Powered by HDBT 2.0 and DSC (Display Stream Compression), the VPX-1401 can transmit 4K@60Hz 4:4:4 8bit video up to 80m /
262 ft via a Shielded Cat 6a/7 cable, with USB 2.0 (Host), bidirectional RS232 and IR pass-through. HDBaseT output also features
PoE (PSE) to power an HDBT receiver.
The VPX-1401 simplies integration and installation of a small presentation system for classrooms and small oces, providing
localized presentation switching support over long distances.
