Chapter 2: Overview
2. Overview
2.1 Introduction
The MediaCento VX Extender pair (Tx + Rx) transmits VGA + Audio + Serial signals
via CATx cable(s). With one Cascadable Receiver and one Long-Range Receiver, it
extends up to and over 450 meters away with WUXGA (1920 x 1200)/Full HD (1920
x 1080) resolution. Via cascading, up to 32 threads and more than 1000 display
units broadcast audio/video signals simultaneously to expand system capability.
Each audio or video port can be independently turned on/off. To ensure video
quality, users may manually adjust video signal on Gain (Brightness), Equalizer
(Sharpness), and RGB skew on all receivers (and cascadable receiver).
However, in some cases display problems may occur because of incorrect EDID
communication between the display monitor and the unit or inappropriate EDID
data programmed by display manufacturers. The EDID Copy function enables the
system to either read the necessary EDID information from the unit or copy EDID
from EDID-compliant displays.
The Graphical User Interface (GUI) is easy to use. You can not only enable or disable
audio/video output simply by clicking the icons, but you can also sort the units by
grouping, which makes management easy. Using the GUI does not need complex
commands. You can portray or rename display icons. The system is ideal for public
broadcasting, exhibits, retail stores, courtrooms, stock tickers, bus stations, etc.
2.2 Features
• Transmit VGA + Audio + Serial signals via CATx technology up to and beyond
1440 feet (450 meters) away with repeaters in between.
• Cascade units to broadcast up to 32 threads to more than 1000 display units;
expand system capability.
• Unique Equalizer (sharpness)/Gain (brightness)/RGB Skew adjustment via push
buttons provides optimal video quality.
• Independently turn ON/OFF the audio and video of the remote ports.
• Automatically detects and indicates the source video signal.
• EDID Copy function.
• Supports surge protection.
• Audible confirmation beeps make operation and cross-checking easier.
• LED indicators monitor status.

4. Operation
4.1 Video Adjustment on Receiver/Cascadable Receiver Unit
To optimize the video signal associated with various cable lengths, users may adjust
the video compensation on the Receiver/Cascadable Receiver Unit. It follows the
order in sequence of: EQ—>Gain—>Skew (Red—>Green—>Blue) —>EQ—>
Gain…
STEP 1: Press and hold the “Mode” button for two seconds. When the “EQ” LED
flashes yellow with one beep, the receiver enters video adjustment mode.
STEP 2: Press the “+” or “-” button once (you will hear a clicking sound) to increase
or decrease one level of video adjustment. You will hear a long buzzer
when the receiver reaches its limit.
STEP 3: Press the “Mode” button to go to the next phase (Gain). The “Gain” LED
flashes yellow with one beep sound. Follow STEP 2 above for adjustment.
STEP 4: Press the “Mode” button to go to the next phase (Skew). The “Skew” LED
flashes red/green/blue with one beep sound. Follow STEP 2 above for
adjustment. The “Skew” LED flashes red, green, or blue to indicate which
color is being adjusted. You will hear a long buzzer sound when the
receiver reaches its limit.
STEP 5: Press and hold the “Mode” button for two seconds. You will hear one beep
when the receiver exits Video Adjustment mode.
NOTE: The timeout is set around 20 seconds.

Chapter 4: Operation
4.2 EDID Setting on a Transmitter
In some cases, display problems may occur because of incorrect EDID
communication between the display monitor and the unit or inappropriate EDID
data programmed by display manufacturers. The EDID Copy function enables the
system to either read the necessary EDID information from the unit or copy EDID
from EDID-compliant displays.
NOTE: Before starting EDID Setting, ensure the Cascade Switch is in the “OFF”
position.
4.2.1 EDID Copy
If the transmitter EDID does not match the EDID of the attached displays, copy the
EDID from the displays.
STEP 1: Apply power to the unit.
STEP 2: Connect the display to the Video Out connector on the transmitter and
power on the display.
STEP 3: Press the “EDID Copy” button and release the button RIGHT AFTER the LED
flashes green.
STEP 4: The LED flashes red and green alternately and returns to normal status,
indicating that the copy is successful.
Otherwise, if the LED flashes RED:
a. The monitor is not properly connected.
b. The monitor is not powered on.
c. EDID data of the monitor is not applicable.
Repeat STEPS 2 and 3.
4.2.2 Use (Load) Default Setting
When using a monitor that is NOT EDID compliant, the transmitter will automatically
select viable EDID data from the transmitter’s EDID profile to set up the EDID
information.
STEP 1: Apply power to the transmitter.
STEP 2: Press the “EDID Copy” button and release the button RIGHT AFTER the LED
flashes red.
STEP 3: The LED flashes red and green alternately and returns to normal status
when the copy is successful.

4.3 Factory Default Settings on Transmitters and Receivers
To restore the transmitters and receivers to the default settings, follow these steps.
4.3.1 Factory Default Setting on the Transmitter
STEP 1: Press and hold the “EDID Copy” button.
STEP 2: Apply power to the transmitter.
STEP 3: Release the button RIGHT AFTER two LEDs flash.
NOTE: A two-beep sound is used to confirm power supply.
STEP 4: Power cycle the unit.
4.3.2 Factory Default Setting on the Receiver
STEP 1: Press and hold the “+” button.
STEP 2: Apply power to the receiver.
STEP 3: Release the button RIGHT AFTER two LEDs flash.
NOTE: A two-beep sound is used to confirm power supply.
STEP 4: Power cycle the unit.

Appendix C: Text-Based RS-232 Protocol
Appendix C: Text-based RS-232 Protocol of MediaCento™ VX
RS-232 Communication setting:
Baud rate: 38400
Data bit: 8
Parity bit: 0
Stop bit: 1
Flow control: none
Letter case: none
The command set has the following format (Command is ASCII format).
(a1.a2.a3.a4.a5.a6)XXX=n,m[CR]
a1.a2.a3.a4.a5.a6
(Optional) The Address packet of the destination device node, variable length, with
a maximum length of 6. This is required when sending a command to destination
node.
When command line doesn’t include an Address packet that indicates this, the
command will be broadcasted to all nodes.
Each byte of an address packet is hexadecimal-text, low nibble is the TX port index
(zero-based), high nibble is Expanded port index (1-based).
The device tree has to follow the rules listed below:
• The first layer only can expand to four splitters.
• You can only can extend to four layers of Repeaters in the device tree.
• You can only can expand one Splitter on a Repeater’s expanded port.
For example, (see the device tree listed below):
(00) – root node, a Splitter
(10) – the node on the expanded port of node (00), a Splitter
(20) – the node on the expanded port of node (10), a Splitter
(30) – the node on the expanded port of node (20), a Splitter
(30.00), a Repeater — The node on the TX port 1 of node (30)
(30.10), a Splitter — The node on the expanded port of node (30.00)
724-746-5500 | blackbox.com Page 39
Page 40
Appendix C: Text-Based RS-232 Protocol
(30.10.00), a Repeater — The node on the TX port 1 of node (30.10)
(30.10.00.00), a Receiver — The node on the TX port 1 of node (30.10.00)
[CR] carriage return ASCII code (hex value = 0x0D), the end of command packet
[LF] line feed ASCII code ( hex = 0x0A )
[ESC] Escape ASCII code
For example,
If you want to set all video on, you can send a command like this:
VEN[CR]
If you want to set the video on node (30.10.00.00), you can send a command like
this:
(30.10.00.00)VEN[CR]
If you want to set the audio on node (30.10.00.00) and all branches, you can send a
command like this:
(30.10.00.00)BS_AEN[CR]
If you want to enable the public audio on node (30.10.00.00) and all branches, you
can send a command like this,
(30.10.00.00)TEMP_AEN[CR]
When the “first” transmitter, which is directly connected to a PC, receives the
command, it will reply with a code:
Correct [CR][LF] (this means the command is correct) or
Incorrect [CR][LF] (this means the command is incorrect)
(*=no change, !=reset default, +=increase, - = decrease, 0= Off , 1= On)
Video default=On, Audio default=On, RS-232 default=On, Buzzer default=On,
EQ default=0, GAIN default =100, RSKW default = 0, GSKW default = 0, BSKW
default =0,
*This is what device is returning to PC.
