Installing Works24 Digital SignageWhile Works24 digital signage is designed to be as simple and easy as

possible, it is still a relatively complicated multimedia installation. These

instructions are designed to help installers complete installations in a timely

manner with a minimum of problems.

Because each installation is unique and equipment is changing rapidly, this

is not a detailed set of instructions to use in every case, but a guide to the

most commonly encountered installation scenarios and problems.

Below is a connection diagram showing a typical installation with three

HDMI screens. This installation is common, but you might have more or

fewer screens, component video, external video, drive-up lanes, a mix of

video types, etc.

For example, if you have a simple, single-screen installation, consider

locating the player at the screen if possible. This will eliminate almost

all video distribution issues (interference, etc.) and greatly simplify your

installation.

IMPORTANT: This diagram represents a typical installation scenario. However, each installation is unique. Yours may be different.

HDMI Video The current standard for digital HD video. The ends of these cables look like fat USB cables.

Component Video Analog HD video, composed of three separate RCA cables, usually colored red, green and blue. A fourth and fifth cable (usually red and white), carry audio.

Composite Video These classic TV video cables are yellow (video), red and white (audio).

DEFINITIONS


Video Over Cat6/5eIf your player will be located separately from the screen(s), such as in a server room or wiring closet, you

will need to run network cabling to carry the video to the screen(s). We use special converter boxes

called baluns (BALancer/ UNbalancer) to convert the video signal to an analog signal for the cable run.

You will run one set of cables from the player location to EACH screen you wish to support.

Balun Examples (yours may not look exactly like these)

Wiring DiagramsBelow are the basic wiring diagrams for the baluns we ship. As a general rule, HDMI baluns require two

cables per screen, and component or composite baluns require one cable. All new installations of VXP

since 2010 are HDMI. All HDMI baluns, and some component baluns include power supplies, either one or

two depending on the brand. Follow the instructions that came with your baluns to be sure the power is

connected correctly.

Component Cable from PC/Splitter/DA


Cabling Do’s and Don’ts

Use high-quality cable and terminate it properly (either 568A/B). BEST - Shielded Cat 6 cable GOOD - Cat 6 cable MINIMUM - Cat 5e cable

Minimize the number of terminations over

the run, the fewer the better. Directly out

of the wall and into the balun at each end

(a straight cable run from transmitter to

receiver) is preferred.

Double-check the termination of your cable.

Correct wire pairs and polarity are critical.

Read the instructions that came with your

baluns. We use several suppliers for video

distribution equipment, and there are slight

differences between brands.

Be sure that the “send” (transmitter) baluns

are located at the player PC, and “receive”

(receiver) baluns are located at each

screen.

DO NOT run cable within 12 inches of

sources of electrical interference. These

include but are not limited to fluorescent

lights, transformers, power boxes and

conduit.

DO NOT exceed the maximum cable

run distance for the baluns. 100 feet is

about the limit for HDMI, and 200 feet for

component, and if you are close to that

you will most likely need to run shielded

Cat6 cable. Check the instructions that

came with the baluns for specifics.

DO NOT run cable through any kind of IP

switching equipment or network hardware.

The video cabling is used “as a wire” and is

not carrying any kind of network traffic.

DO NOT mix brands of baluns over a

single run. The brand and model of the

transmitter MUST match that of the receiver.

When using HDMI baluns with two cables DO NOT cross the cable connections at

each end. The converters are marked

and each cable must run to its matching

connection on the other end.

DO NOT split the cables or attempt to drive

more than one receiver per transmitter. A

transmitter can support only one receiver.

DO

DO NOT


Distribution AmplifiersIf your player will be driving multiple screens, you will be provided with a

distribution amplifier, to be located at the player PC. There are several

issues that can crop up with connecting multiple screens via HDMI DA;

we’ve addressed the most common below.

HDMI is two-wayHDMI uses digital two-way communication between the player device

and the screen to negotiate resolution, refresh rate, etc. Because a splitter

must drive more than one screen, only one of its ports will be two-way.

THIS PORT MUST ALWAYS BE CONNECTED FOR ANY OF THE SCREENS TO GET

A SIGNAL. This is usually port 1 or A, but check the instructions that came

with your device.

When installing multiple screens, first get one screen up and running, connected through port 1 (or whichever port is the two-way port) on the DA, then connect the other screens.

Composite Video Conversion (Drive-up)If you have a drive-up system or other video display device that requires

a composite (standard) video connection, we will include a device that

converts the high-definition (HDMI or composite) signal to a standard video

signal.

Examples of two of the devices we ship are shown below. Video is run to

the display connection as normal, then the device is used to downsample

(resize) the picture for standard video.

IMPORTANT: Because we are resizing HD (1280x720) video to SD (640x480),

content with small text can be hard to read.

External Video CaptureWe strongly recommend against running external content on your

displays for the following reasons:

• Risk of displaying competitors’ ads on your screen to your

customers

• Risk of offensive/inappropriate content

• Distracts from your marketing message

However, our system does include the ability to display standard-

definition external video as part of the playlist if requested.

External video limitations

• Video must be standard-definition, analog cable on coax or a composite signal on RCA or S-Video

coming from a cable or satellite box.

• The built-in tuner can tune standard channels from 2 to 125. It cannot tune digital, HD or encrypted

(pay) channels.

Run a separate cable/satellite signal directly to the televisions outside of the VXP service. That way, in the case of inclement weather, sporting event, community event, etc., you can switch the television directly to regular TV temporarily.

Troubleshooting Balun/Video Issues

Problem:

HDMI or Component — TV showing “no signal” or black screen (HDMI and Component)

Check first (and double-check!):

✔ Power “On” on PC (check lights)

✔ Power “On” on TV (check lights)

✔ TV tuned to correct input source, usually HDMI 1 or 2 or Component/CMP 1 or 2

✔ All wiring connected correctly (wires not crossed, no loose cables)

✔ Power LED lit on powered baluns (see manufacturer’s instructions)

✔ Read manufacturer’s instructions included with baluns. Most HDMI baluns, and some component

baluns, have adjustments for gain/impedance, etc. Follow those directions to test different

settings. ✔ Before continuing to “next steps,” call Sharon or Jason at Works24 support, 800-460-4653.

Next steps:

✔ Either bring PC to screen or screen to PC (pick one screen for multi-screen installations). Connect

HDMI/Component directly from screen to PC, power on PC and screen.

✔ Double-check all connections, TV tuned to correct input source

If you have a picture when connected directly to the TV, it’s an issue with the baluns/DAs/cable runs.

Check:

✔ Check house cabling again, use a cable tester if possible

✔ Check connections again

✔ Test baluns with short patch cables (bypass cable run through building)

If it works with short cable run (patch cables), the issue is with the installed cabling.

Check:

✔ Cabling not run over 100 feet for HDMI, 200 feet for component

✔ Cabling not run over fluorescent lights or other sources of electrical interference

✔ Check wiring with cable tester

✔ Check connections on HDMI baluns are not crossed ✔ If still no picture, call Sharon or Jason at Works24 support, 800-460-4653.

Troubleshooting Balun/Video Issues cont’d.

Problem:

HDMI only — TV intermittently losing signal (such as between clips) OR “Sparklies” on screen or distorted/

pixelated picture

This usually indicates the signal is “borderline.” The signal is weak, causing the TV to stop detecting the

presence of the player, usually when the screen goes black between clips.

Check:

✔ Cabling not run over 65 feet

✔ Cabling not run over fluorescent lights or other sources of electrical interference

✔ Check wiring with cable tester

Solutions:

✔ Replace wiring with shielded Cat6

✔ Move PC closer to screen(s)

✔ If the problem is not solved, call Sharon or Jason at Works24 support, 800-460-4653.

Problem:

Component only — Black/white or tinted picture (colors off)

✔ This usually indicates one of the three component cables (red, green, blue) is crossed somewhere

along the signal path.

Check:

✔ Red audio cable and red video cable not switched

✔ Cable colors match at every connection (all baluns, DA, and PC)

✔ Correct adapter used from PC to component video

✔ If the problem is not solved, call Sharon or Jason at Works24 support, 800-460-4653.
