INTRODUCTION
Thank you for purchasing this Blackbird™4K HDBaseT™1x4 Splitter Extender! This device
accepts a single HDMI® input and splits it into four HDBaseT outputs. It features an HDMI
loop out, which allows up to three additional devices to be cascaded. It supports video
resolutions up to 4K@60Hz and all HDMI audio formats. It can extend 1080p signals on
each output to distances up to 196 feet (60 meters) and 4K signals to distances up to 131
feet (40 meters) over a single Cat6 Ethernet cable. It supports the Power over Cable (PoC)
feature, which allows the receivers to be powered from the transmitter over the Ethernet
cables. It supports bidirectional IR and RS232 pass-through and loop output.

PRODUCT OVERVIEW
Transmitter Front Panel
1. POWER LED: The LED illuminates red when power is applied.
2. FIRMWARE: USB port for connecting a flash drive to perform a firmware update.
3. INPUT LED: The LED illuminates green when there is an input signal present.
4. OUTPUT LED: A block of LEDs to indicate the condition of the input and output
signals:
HDMI: The single HDMI LED illuminates green when the HDMI® source signal
contains HDCP data. It blinks green when the HDMI source signal does
not contain HDCP data and is off when there is no HDMI source signal
present.
LINK: Each LINK LED illuminates green when there is a valid connection between
the transmitter and each of the four receivers.
HDCP: Each HDCP LED illuminates green when the corresponding receiver
supports HDCP and blinks green when the corresponding receiver does
not support HDCP. Each LED is off when there is no connected
corresponding receiver.

Transmitter Rear Panel
1. HDMI INPUT: HDMI® port for connecting the HDMI source device.
2. OUTPUTS: The OUTPUTS section contains an HDMI loop output and four HDBaseT™
RJ45 jacks with PoC support.
3. IR: A 3.5mm IR IN jack for connecting an IR receiver (not included), a 3.5mm IR LOOP
output jack for cascading to another device, and a 3.5mm IR OUT jack for connecting
an IR transmitter (not included).
4. ID PRESET: Assigns a single digit ID to the transmitter. When cascading multiple
transmitters and using RS232 control, each transmitter must have a unique ID. Use a
small, flathead screwdriver to set the ID. There are sixteen positions, with 0at the
fully counterclockwise position and 15 at the fully clockwise position. After setting
the ID, the device must be restarted for the new ID to take effect.
5. RS232: Two 3-pin RS232 connectors. Connect the included 3-pin to DB9 cable to the
IN connector, then connect the other end to your PC. If cascading multiple units,
use the included 3-pin RS232 cable to connect the LOOP output to the RS232 IN on
the next device in the chain.
6. EDID: Four DIP switches for setting the Extended Display Identification Data (EDID)
value.
7. DC 24V: DC barrel connector for connecting the included AC power adapter.

8
Receiver Front Panel
1. LINK LED: The LED illuminates green when there is a successful link between the
transmitter and the receiver. It blinks green when there is a problem with the link
and is off when there is no link.
2. HDCP LED: The LED illuminates green when there is valid HDMI® traffic with HDCP
content. It blinks green when there is video traffic without HDCP and is off when
there is no traffic.
3. POWER LED: The LED illuminates green when power is applied.

9
Transmitter Rear Panel
4. RS232: A 3-pin RS232 connector. Connect the included 3-pin to DB9 cable to the
RS232 connector, then connect the other end to your PC.
5. IR IN: 3.5mm jack for connecting an IR receiver (not included).
6. IR OUT: 3.5mm jack for connecting an IR transmitter (not included).
7. HDMI OUT: HDMI® connector for connecting a video display.
8. HDBT IN: RJ45 jack for connecting the Cat6 cable from the transmitter.
9. DC 24V: DC barrel connector for connecting the included AC power adapter.

SAMPLE CONNECTION DIAGRAM
Use the following sample connection diagram as a guide for connecting the Blackbird™ 4K
HDBaseT™1x4 Splitter Extender with up to four HDBaseT PoC Receivers (not included).

11
CASCADING
In addition to the main unit, you can cascade up to three additional units to distribute the
video signal to up to sixteen video displays. Use the following connection diagram as a
guide for cascading multiple units. Note that each unit must have a unique ID if using
RS232 control.

12
IR CONTROL
You can connect an IR receiver and transmitter to the system to allow for IR control of
remote devices. The IR feature is bidirectional, so you can control either the source or
display device(s). Use the following sample connection diagrams to connect for IR remote
control.

EDID MANAGEMENT
The Extended Display Identification Data (EDID) is used by the source device to match its
video resolution with that of the connected display. By default, the source device obtains
its EDID from the first connected display. However, since displays with different
capabilities can be connected to the splitter, the EDID DIP switches can be used used to
set the EDID to a fixed value. Note that the default setting is the only way to distribute 4K
video.

RS232 CONTROL
The Splitter Extender and compatible receivers (not included) can be controlled from a
computer using the included 3-pin to DB9 RS232 cable and a third party RS232 control
software, such as CommWatch. Compatible receivers must be able to communicate at
2400, 4800, 9600, 19200, 38400, 57600, or 115200 baud. The Splitter Extender requires the
following communication protocol parameters:
9600 baud rate, 8 data bits, 1 stop bit, no parity bits
