CAT5 MULTI VGA SYSTEM

2. Introduction

2.1 Overview

The CAT5 Multi VGA System extends VGA video signals over ordinary Category 5 cable. All models support RGBHV, RGB, and VGA video, and they use a transmitterto-receiver setup. They can be used as video splitters as well as video extenders.

This manual covers CAT5 Multi VGA System Transmitters and Receivers with Audio (AC1000A–AC1003A) and CAT5 Multi VGA System Transmitters and Receivers with RS-232 (AC1004A–AC1007A). Their respective Rackmount Kits (AC1008–AC1012) are discussed in Appendix D.

The video/audio models enable you to broadcast line-level mono audio, along with video from your computer, to as many as 100 computer monitors up to 450 feet (137.2 m) away over CAT5.

The video/serial models transmit VGA signals at the same 450-ft. distance to RS232 devices, such as touchscreen displays or newer plasma monitors that have RS232 serial inputs. They do this by transmitting full modem serial signals along with the video signals over CAT5.

Among the transmitters available for both video/audio and video/serial models are single-port models and four-port (quad hub) versions. The quad hub transmitter is used to distribute the same signal to multiple display devices. Setup and cabling are the same as the single-port transmitters.

When using the quad hub serial transmitter model (AC1003A) with daisychained receivers, serial communication mode is unidirectionally broadcast. In this mode, all other CAT5 Multi VGA System devices must be of the simplex serial type.

CAT5 Multi VGA System receivers are available with single or dual daisychainable connections. The dual daisychainable receiver is used when the same signal is distributed to multiple display devices across a single CAT5 cable in a daisychain or loop-through fashion. Setup and cabling are the same as the single-port receiver.

The single-port serial transmitters and single-port and dual daisychainable serial receivers contain an internal Universal Digital Board (UDB) that can be reconfigured from its default setting for simplex operation to bidirectional operation. This way, you can connect touchscreens and high-end video projectors with interactive features. The bidirectional setting isn’t an option on the the quad hub models because they broadcast serial data in one direction only.

CHAPTER 2: Introduction

All models support refresh rates/resolutions up to 1280 x 1024 @ 75 Hz at up to 450 feet (137.2 m) and 1600 x 1280 @ 75 Hz up to 400 feet (121.9 m).

WARNING

This equipment is not intended for, nor does it support, distribution through an Ethernet network. Do not connect these devices to any sort of networking or telecommunications equipment!

2.2 Package Contents

• The transmitter or receiver.

• External power supply (100–250 VAC, 50–60 Hz, autosensing) with cord.

• This manual (transmitters only).

2.3 Equipment You May Also Need

• Rackmount Brackets: For single-port transmitters or single-port/dual daisychainable receivers:

AC1008 for 1 unit; AC1009 for 4 units; AC1010 for 8 units;

For quad hub transmitters: AC1011 for 3 units; AC1012 for 6 units.

• Audio cable with RCA jacks.

• Video cable with HD15 connectors.

• Serial cable with DB9 connectors.

• CAT5 cable.

• For the single-port audio models, an audio splitter.

2.4 Compatible Cabling

CAT5 cabling for the CAT5 Multi VGA System must be pinned to the TIA-EIA T568B wiring specification. We also highly recommend that all CAT5 cables be pre-terminated and tested. Cables terminated on-site or in an existing infrastructure should be tested before use to ensure compliance with the TIA-EIA T568B specification. Using incorrectly terminated CAT5 cables can damage the CAT5 Multi VGA System.

CAT5 MULTI VGA SYSTEM

3. Setup and Installation

3.1 Data Mode Configuration

For serial 1-port versions only: Configure the internal Universal Digital Board (UDB) if you want to change the transmitters/receivers from simplex operation (default) to bidirectional operation. (See Appendix C.) This configuration should be done before making any cable connections and applying power.

3.2 Cabling Considerations

• We recommend mounting and connecting all cabling to the CAT5 Multi VGA

System components before applying power.

• Makes sure that the CAT5 cable you intend to use has been tested to comply with

the TIA/EIA 568B wiring specification.

• We recommend that you use only CAT5 cable with the CAT5 Multi VGA System.

If you must use CAT5e or CAT6 cable, call Technical Support.

3.3 Making the Connections

3.3.1 C

ONNECTIONS ANDSETUP INGENERAL

This section contains figures showing connections with the specific CAT5 Multi VGA System models. In general, however, the connection and setup procedure at both transmitter and receiver ends is as follows:

At the transmitter end:

1. Connect the source video to the CAT5 Multi VGA System transmitter video input

port, which is an HD15 connector labeled SOURCE IN.

2. If desired, attach a local monitor via the local monitor port to LOCAL OUT.

NOTE

The single-port units with audio have a single audio input. So, for audio capabilities on the attached monitor, you’ll need an audio splitter.

3. Make your audio or serial connections.

For audio versions: Connect the audio input to the AUDIO jack. For RS-232 versions: Connect the serial input to the RS-232 (DB9 female) port.

CHAPTER 3: Setup and Installation

4. Connect the CAT5 cable to the transmitter.

5. Apply power on the transmitter. The LED should light and, if there’s a local

monitor attached, a video image should appear on the monitor’s screen.

At the receiver end:

1. Connect the SOURCE OUT HD15 connector to the display unit, and attach any

audio or serial connections depending on the model of CAT5 Multi VGA System (see Sections 3.3.2 through 3.3.5 for model-specific connections).

2. Make sure that the CAT5 cable connection(s) from the transmitter are secure.

3. Apply power. The LED should light and video should appear on the display

(make sure display is powered ON).

4. For video clarity, adjust the 3-position compensation switch, which optimizes the

image for the length of CAT5 cable used (long, medium, or short).

If there are any problems at either end, see Chapter 4.

CAT5 MULTI VGA SYSTEM

4. Troubleshooting

4.1. Common Problems

In most cases, nearly every issue with the CAT5 Multi VGA System can be resolved by checking the CAT5 termination and making sure that it’s pinned to the TIA/EIA 568B wiring specification. However, there may be other problems that cause the system to not perform as it’s designed. Below are solutions to the most common installation errors.

Problem: No video signal at the transmitter local port or at the receiver.

Solution: • Check that both units are powered.

• Make sure the CAT5 cable is terminated correctly per the TIA/EIA 568B wiring specification.

• Is the display device powered on and functioning? In some cases, the video termination may be mismatched. The transmitters and receivers ship with 75-ohm termination as the default. To disable termination, see Appendix B.

Problem: Video signal is poor.

Solution: • Is the compensation switch on the receiver in the correct

position?

• Check all cable connections.

• The video signal’s refresh rate may be set too high. Reset to a lower refresh rate in your monitor-configuration menu.

• There may be a delay skew issue. Call Technical Support.

Problem: Audio is poor.

Solution: • Powered speakers are required. Make sure speaker power is

ON.

• Check input source levels from the source device. Make sure the audio source is not overdriven or underdriven.

CHAPTER 4: Troubleshooting

Problem: Serial communication doesn’t work correctly.

Solution: • Are the serial devices connected properly? Are the serial

parameters correct for source/destination devices?

• Are the serial cables terminated correctly? If a null-modem cable is used, it must be placed at the receiver end.

• When using RS-232 transmitters or receivers, the serial signal is a unidirectionally broadcast mode only. In this mode, all other CAT5 Multi VGA System devices must be the simplex serial type. For assistance, contact Technical Support.

• The last device in a quad hub or daisychain configuration must be a standard receiver unit with a terminated serial board (default).

Problem: “Blue shift” of video signal (a slight blue haze appears in areas of

the screen that normally would appear black, or a slight blue tint appears in areas that would normally appear white). This is most often seen in applications that use inexpensive monitors, but it sometimes occurs with more expensive equipment.

Solution: 1. Go into the monitor’s menu and select the “Blue-Black Level”

function.

2. Use the appropriate command to reduce the level.

3. Reduce the “Blue-Black Level” until the black areas in the

image truly appear black. For monitors with a “Blue Drive” adjustment, reduce this setting until the white areas of the screen appear normal.

Problem: “Green shift” or “green washout” on multimedia signals.

Solution: Please contact Technical Support.

The standard video/serial model (AC1004A–AC1007A) is designed to function with DC coupled signals in which the black level is referenced to 0 volts. Nearly all VGA cards function this way.

Some media servers, however, provide AC coupled signals and can cause a green color shift in the video. This is a result of the

CAT5 MULTI VGA SYSTEM

sync clamping on the red and blue channels of the video/serial model.

For five-component (RGB/H&V) AC coupled video, an optional DC restoration adapter needs to be installed between the ACcoupled source and the transmitter. Technical Support can provide you with ordering and installation information.

4.2 Calling Black Box

APPENDIX B: Setting Sync Signal Output Termination

Appendix B.

Setting Sync Signal Output Termination

In some cases, it may be necessary to disable the 75-ohm termination of the video outputs on the CAT5 Multi VGA System units. This can be done by opening the case of each unit and installing jumpers on the circuit board. The settings disable/enable the 75-ohm termination on individual units. For instance, changing a transmitter termination affects the local monitor port only; it doesn’t affect the receivers. Conversely, changing a receiver affects the output port of the receiver, not the transmitter. The following diagrams show the jumper locations for each type of assembly.

The UDB hardware configuration is done via jumper settings. These jumpers are used to route signals to the interface port(s) for the DB9 connector and to configure the transceiver for RS-485 operation.

To access the UDB on these transmitter and receivers:

1. Make sure the unit is powered OFF.

2. If necessary, unplug all cables to the unit.

3. Unscrew the top screw as well as the two set screws in the DB9 connector. Lift the cover off.

For reference Table C-1 shows the input/output jumper configuration for the DB9 connector as it’s currently pinned on the board.

NOTE:

1. JP-2, JP-10, and JP-11 are reserved (not currently used).

2. JP-3 configures the RS-485 transceiver for unidirectional or bidirectional operation.

3. JP-4, JP-5, JP-6, and JP-7 are used for IR configurations only (not currently used).

4. JP-9 controls the RS-485 termination.

5. JP-12 selects simplex or duplex operation.

Figure C-1 shows the board for the Single-Port CAT5 Multi VGA System, RS-232 Transmitter (AC1004A). Figure C-2 illustrates the UDB for both CAT5 Multi VGA System, RS-232 Receivers (AC1005A and AC1006A).

Appendix D. Rackmounting Units

The Rackmount Kits include brackets for mounting a single transmitter, single receiver, or a single dual daisychainable receiver. Figure D-1 shows the 1-Unit Rackmount Bracket (AC1008), which can be used to mount a single CAT5 Multi VGA System unit on a wall. Figure D-2 shows the 4-Unit Rackmount Bracket (AC1009), which holds four units in a 19" x 1U rack.

Not shown are brackets for 8 units and brackets for quad hub transmitters. The 8Unit Rackmount Bracket (AC1010) holds the mounted units like the 4-Unit Rackmount Bracket (AC1009) but is 2U high instead of 1U high, stacking 4 slots directly above 4 slots. The 3-Unit Quad Hub Transmitter Bracket (AC1011) is like the AC1009 but holds 3 units instead of 4 in a 19" wide x 1U high panel. The 6Unit Quad Hub Transmitter Bracket (AC1012) is like the AC1011 but occupies 2U of space instead of 1U in a 19" rack, stacking 3 quad hub transmitters atop 3 quad hub transmitters.
