1.2 DDC/EDID Support
For best compatibility with source devices (for example, a PC), an extension device (CAT5 Multi VGA and Analog Audio
Transmitter in this case) should provide an appropriate DDC/EDID profile with the proper resolution and timing information. This
helps ensure best compatibility with display devices connected at the remote end.
The transmitter supports a simple, yet very flexible, DDC/EDID management scheme:
• The built-in factory-default DDC/EDID profile supports a number of standard resolutions and timing information that is widely
compatible with many displays.
724-746-5500 | blackbox.com
Page 6
Chapter 1: Specifications
• A specific DDC/EDID profile can be copied from a particular display and stored inside the transmitter’s internal non-volatile
memory. This method enables the best possible compatibility with a specific display that would otherwise not work properly if
simply using the factory-default DDC/EDID profile.
• Finally, the transmitter supports a “pass-through” mode, where the DDC/EDID profile of a locally attached display is passed
directly to the video source. This can be very helpful in diagnosing certain resolution or timing related display issues, but
generally is not used on a permanent basis (though it is safe to do so).

1.3 Auxiliary Signal Support
The transmitter design supports two types of auxiliary signals, preconfigured from the factory.
NOTE: Only one type of signal is supported at a time.
The CAT5 Multi VGA and Analog Audio Transmitter supports L+R summed audio.
It also supports the following serial signals:
• Provides simplex (TX-only) serial data, even with daisychained receivers.
• Data is transmitted to all attached receivers. No data can ever be received.
• Receivers are not individually addressable.
• RS-232 interface supports a 2-wire interface: TX/GND.
• Baud rates up to 115.2K are supported. No settings required.
• Transparent to format and protocol.
NOTE: For each transmitter configuration above, the accompanying receiver device must be similarly configured.
For more specific information on CAT5 Multi VGA and Analog Audio receivers, please refer to the user guide provided with your
re cei ver.
1.4 CAT5 Cable Compatibility
The CAT5 Multi VGA and Analog Audio Transmitter enables the highest quality video extension over common Category 5 (CAT5)
cable. In some applications, system design or environmental factors can require the use of CAT5e and CAT6 cabling (with and
without optional shielding). Each installation may have special requirements, and it is up to the system designer to determine the
most appropriate type of cable to deploy with CAT5 Multi VGA and Analog Audio Transmitter products.
724-746-5500 | blackbox.com
Page 7
724-746-5500 | blackbox.com
Chapter 1: Specifications
CAUTION: In any case, if there is any doubt with regards to a specific type of cable, it is strongly advised that actual testing be
performed using an appropriate length of the desired cable—BEFORE that cable is specified and installed.
The transmitter provides four UTP output ports. Each port in turn supports a daisychained CAT5 connection to multiple receivers.
This allows one video source to be sent to many displays at the same time—with the absolute minimum amount of signal
degradation possible.
The transmitter is compatible with standard CAT5/5e/6 data cabling as well as specialized “low skew” cabling manufactured
primarily for video applications.
CAUTION:
Some “low skew” cabling is specific to a particular equipment vendor or application and may not be compatible with CAT5 Multi
VGA and Analog Audio Transmitter products. Make sure that any “low-skew” CAT5 cable is non-proprietary prior to purchase/
installation.
Standard CAT6 cable can exhibit much greater skew than standard CAT5/5e and may require skew compensation beyond what
the standard product offers. Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com for details.
The CAT5/5e/6 cable should be suitably rated listed (DUZX) communications cables, TYPE CMP, CMR, CMG, or CM as
designated in the NEC. Cables are to be installed in accordance with the NEC and local building and electrical codes. This is the
responsibility of the end user/installer of this product.

Chapter 3: Installation
3. Installation
CAT5/5e/6 cabling for the CAT5 Multi VGA and Analog Audio Transmitter must be pinned to the TIA-EIA T568B wiring
specification.
Figure 3-1. T568B CAT5 Specification.
CAUTION: We also highly recommend that all CAT5 cables be preterminated 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 transmitter.
CAUTION: 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.
NOTE: Do not connect DC power until instructed to do so.
3.1 Prerequisites
Depending on the specific installation requirements, some common tools (screwdrivers, nutdrivers) and related hardware (mounting screws) may be required. These are not included with the transmitter.
You might need the following items. For details, contact Black Box Technical Support at 724-746-5500 or info@blackbox.com.
• Appropriate audio cabling.
• Appropriate video cables and adapters (if needed).
• Auxiliary signal cables.
Of course, you will need appropriate CAT5 cable, as previously described, to connect the transmitter to receivers.
3.2 Installation Procedure
NOTE: All units must be configured alike for all supported features to function correctly. For example, a serial transmitter must be
connected to a CAT5 Multi VGA and Analog Audio serial type receiver for the serial interface to function properly. You
cannot mix one version of a transmitter with a different version of a receiver.

Chapter 3: Installation
NOTE: Make sure that all connectors are clean and free of contaminants before making the connections. Use appropriate
connector locking hardware (screws/latches) to prevent cables from disconnecting or causing intermittent operation.
At the transmitter end:
1. Connect the source video to the CAT5 Multi VGA and Analog Audio Transmitter’s video input port, which is a standard HD15
female (VGA) connector labeled SOURCE IN.
2. If desired, attach a local monitor to the VGA connector labeled LOCAL OUT (optional).
3. Connect up to four CAT5 cables to the transmitter LINK OUT ports. All link-out ports have the same signals—it does not
matter what order they are used in.
4. Make your audio or serial connections via the Phoenix AUX IN and AUX OUT connectors (optional).
5. Apply power to the transmitter.
a. The power-on LED should turn on. All other LEDs should execute a power-up test sequence.
b. If the video source is providing a valid RGBHV video signal, the Video Status indicator should turn on.
NOTE: It will remain off for YUV, S-Video, and any other analog formats that do not use separate H/V sync signals.
c. If there’s a local monitor attached, a video image should appear on the monitor’s screen.
6. Remember to make any required transmitter configuration changes via the LED/button user interface.

Chapter 3: Installation
4. Make any required configuration changes via the LED/button user interface, if the receiver is equipped with this capability. This
is for skew compensation.
5. Adjust the receiver’s EQ and/or SKEW (optional) settings.
NOTE: If this adjustment is not made, it can result in a poor or no image on the display.
3.3 Configuration
The transmitter has a number of configurable operating parameters, and the factory-default settings will work in most
applications. However, some applications may require configuration changes. Nearly all settings are available from the front-panel
buttons/LEDs. The enclosure does not need to be opened; there are no user-configuration settings or jumpers inside.
3.3.1 DDC Mode Selection
The CAT5 Multi VGA and Analog Audio Transmitter features the ability to send DDC/EDID display identifiers to the video source
to determine display capabilities. The DDC/EDID interface is a data communications channel used between plug-and-play devices
to accurately report a display's capabilities and identify the manufacturer. If this data is not available, the video source may revert
to a low resolution or not display at all. The transmitter has three DDC/EDID modes of operation. When the T4 is operating in
“normal mode” (CFG indicator is off), you can quickly select between the three operating modes simply by using the DDC MODE
button at any time:
• STD: Selects the default DDC profile (a default set of common video resolutions). Press the DDC MODE button until the STD
indicator (LED 6) is on. This is the factory default setting.
• LOCAL: Selects the DDC profile from a locally connected display. Press the DDC MODE button until the LOCAL indicator (LED 7)
is on. The LOCAL mode allows the video source device to directly read the DDC profile from the locally connected display (if
present).
NOTE: LOCAL mode does not store any DDC profile information inside the transmitter.
• COPY: Selects a previously stored copy of a DDC profile. Press the DDC MODE button until the COPY indicator (LED 8) is on. To
use the COPY mode, a DDC profile must have already been read and stored into the transmitter.
• To perform a DDC-copy operation, make sure the COPY mode is selected (LED 8=on), then:
1. Connect a display to the LOCAL OUT port.
2. Push and hold the COPY button until the copy-status indicator flashes three times, indicating a successful operation. If it only
flashes once, the operation failed, and the previously stored DDC profile (if any) will remain unchanged.
3. If desired, disconnect the display from the LOCAL OUT port.
3.3.2 General Configuration Settings
For all other configuration settings, the transmitter must be in CONFIG mode (CFG indicator is on). Once in CONFIG mode, any
changes are effective immediately and are saved in non-volatile memory.
• To enter configuration mode1: Press the CFG button once. The CFG indicator will light, confirming that you are in configuration-
mode 1. Once in this mode, the LED indicators 1–8 will display the current settings as described in Tables 3-1 through 3-4.
• To enter configuration mode2: Press CFG button twice. The CFG indicator will flash, confirming you are in configuration-mode
2. Once in this mode, the LED indicators 1–8 will display the current settings as described in Tables 3-1 through 3-4.
• To exit configuration mode: Leave the buttons untouched for 10 seconds. The CFG indicator will turn off (normal mode).
3.3.3 Setting Factory Defaults
To quickly reset all user-configurable options back to factory default settings:
1. Disconnect the DC power cable (or AC power).
2. Press and hold the CFG button.
724-746-5500 | blackbox.com
Page 13
724-746-5500 | blackbox.com
Chapter 3: Installation
3. Connect the DC power cable (or AC power). All LEDs blink three times, indicating all settings are now changed back to factory
defaults.
4. Release the CFG button.
NOTE: The factory default settings represent the analog version. You can easily reconfigure this device to be a serial by using “con-
figuration mode 1” and “4th-pair settings.” See below.
3.3.4 Config Mode 1: Sync Mode Options
The transmitter is factory-configured for autodetecting the proper sync mode (RepliSync-I normal/stretched). This mode is
generally compatible with all existing receiver products that support sync (if they are also using their factory-default settings).
However, some video sources may require a custom sync mode setting (especially at 1080p and 1920 x 1200 video resolutions).
For these cases, you can select one of the other available sync modes.
NOTE: Any connected receiver should generally be set to the same sync mode and may require other configuration adjustments
(such as sync polarity). Otherwise, you may not get a proper video display output at that receiver.

Chapter 4. Troubleshooting
4.1 Problems/Solutions
In most cases, nearly every issue with the CAT5 Multi VGA and Analog Audio CAT5 Video 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 not to perform as it’s designed. Table 4-1 explains the most common installation errors and their
solutions.
Table 4-1. Common installation errors and solutions.
Problem Solution
1. Check that both units are powered.
2. Make sure the receiver EQ and SKEW adjustments are set correctly.
3. Change EQ settings slowly to allow the display to re-acquire a valid signal and display the image.
4. Make sure the CAT5 cable is terminated correctly per the TIA/EIA 568B wiring application.
No video signal at the transmitter local port or at
the receiver.
5. Is the display device powered on and functioning?
6. Check to make sure display settings (resolution, refresh rate, etc.) are compatible with the input signal.
7. In some cases, the video termination may be mismatched.
8. Generally, transmitters and receivers ship with 75-ohm termination as the default. Refer to applicable user guides to
change the termination settings.
9. There may be a DDC/EDID compatibility problem. Try changing the DDC mode setting or copying the DDC/EDID
profile directly from the display.
1. Make sure the receiver EQ and SKEW adjustments are set correctly.
2. Change EQ settings slowly to allow the display to re-acquire a valid signal and display the image.
3. Check all cable connections.
Poor video quality at the receiver.
Poor audio quality.
4. The video signal’s refresh rate may be set too high. Reset to a lower refresh rate in your display configuration menu
(for example, under Windows
5. There may be a video-skew delay issue. See the section on skew adjustment s in the applicable receiver manual.
6. There may be a DDC/EDID compatibility problem. Try changing the DDC mode setting, or copying the DDC/ EDID
profile directly from the display.
1. The audio output at the receiver is line-level only. An amplifier or powered speakers are required. Make sure the
amplifier or speaker power is on.
2. Check input source levels from the source device. Make sure the audio source level does not exceed the audio input
ratings for the transmitter. Clipping or distortion can result.
3. Audio is summed left and right for “A” versions. If using a single channel, both audio inputs must be connected at the
transmitter end to obtain proper audio gain through the link (1:1, input to output).
4. If daisychaining, audio termination should be removed in DP rceivers. Only the last receiver requires termination.
NOTE: The transmitter is NOT compatible with equipped receivers.
NOTE: Table 4-1 is continued on the next page.

Chapter 4: Troubleshooting
Table 4-1 (Continued). Common installation errors and solutions.
Problem Solution
1. Are the serial devices connected properly?
2. Are the serial parameters correct for source/destination devices?
Serial communications do not work correctly
NOTES on Daisychaining: When using a receiver’s RJ-45 daisychain port, the following rules apply:
• If using L/R summed audio, simplex serial, or SPDIF units, a maximum of 12 units may be daisychained within the rated cable
length of the receiver.
3. Are the serial cables terminated correctly?
4. Is a null-modem cable required at the TX or R X end?
5. When using RS -232 (CAT5 Multi VGA and Analog Audio Transmitter S type) capable receivers with video switches, distribution amps, or multi-output transmitters, the serial data is sent transmit-only. Consider this when trying to
control displays or other devices. For help, contact Black Box Technical Support at 724-746 -5500 or info@blackbox.com.
• When daisychaining, the maximum cable distance is not increased beyond the rated distance of the receiver used. For example,
a receiver can only daisychain up to the allowed distance of the transmitter. It is possible to daisychain out of a short-range
receiver into a longer-range receiver to increase the range. For example, a receiver can be daisychained into a receiver that
allows longer daisychaining distance.

A.4 DC Power Connector
You should use the power supply that’s included with the transmitter. However, if there is a reason a substitute power supply
must be used, then the following information is important for maintaining product reliability and performance:
Power supply output rating: Regulated +5-VDC @ 3-Amps.
Power-input rating for CAT5 Multi VGA and Analog Audio Transmitter: 5-VDC, 1-Amps max.
The transmitter’s DC power input connector accepts an industry-standard coaxial-DC plug with the following specifications:
• Coaxial power connector
• Outside diameter (OD) = 5.5 mm
• Inside diameter (ID) = 2.5 mm (accepted center-pin diameter)
• Length = 11 mm (overall length of insertable plug end)
• Inner contact (pin-socket) = +5VDC
• Outer contact (sleeve) = Ground
We recommend that the inner contact (center-pin contact) of any mating DC plug use a “tuning-fork” shaped design, rather than
a plain barrel shape. The tuning-fork design greatly increases the reliability of the power connection. The plain barrel style connector can cause intermittent operation, often resulting in “mysterious” system problems that are difficult to identify.
The provided power supply already comes with the correct output ratings and DC-plug configuration.
Figure A-5. Plain barrel center contact.
Figure A-6. Tuning-fork center contact (PREFERRED).
The power supply included with your transmitter already has the correct output ratings and DC-plug configuration.
