devices as input source.
Using 40nm high-end programmable FPGA chip, full
hardware real-time processing architecture, ultra-fast
processing speed without delay.
1.2. Application scenarios
It is mainly used in industrial applications such as
ultra-high-definition video surveillance, large screen walls,

BIT_V406R front panel
A: Industrial seat, RS232 control loop out, used in cascade
mode to loop out RS232 commands to the next device.
B：Network interface, TCP network protocol, is used for the
control system to issue instructions to control the device.
C：Industrial seat, used for RS232 control, used to issue RS232
commands.
D：Dip switch (Board id): indicates the ID of the current device
in cascade mode.V406 does not support this function, only
V409 supports it.
E：IR is used for receiving remote control signals,Need external
IR receiver.
F, G, H ， I: 4 HDMI input ports, of which I port is 4K60,
F/G/H port is 4K30, suitable for graphics card output on PC

host or other devices. There is an LED light next to each HDMI
interface. The light indicates that the HDMI interface has a
signal input.
J: 1 DP input interface, 4K60 input, suitable for graphics card
output on PC host or other devices.
K: Audio output interface, used for audio output devices:
earphones, etc.
L: DP ring output interface, when multiple devices are
cascaded,It acts as a DP input source for other devices or
displays. The LED light (loop) next to the interface indicates
that there is a loop-out signal output.
(In single-screen mode, the loop-out follows the selection of
the input source channel to switch. In non-single-screen
mode, only the loop-out DP signal is supported).
M: Power switch

N: Power interface, connect to 12V@2AAC-DC power supply.
O: LED light (power) next to the interface.It is a power
indicator. The LED lights when the device is normally powered.
P: Connect the light, which means the video signal is
connected normally.
Q, R, S, T, U, V: 6 HDMI output interfaces, used to
connect display devices such as monitors, televisions or
monitors. There is an LED next to each HDMI interface.The
light is on, indicating that there is a signal output from the
HDMI interface.
Note 1: DIP switch,when cascading, it indicates the ID number
of the current device, which is set in binary.

Remote control operation instructions
The adjustment of the following two groups of parameters
needs to press the [Ent] confirmation key to take effect, and
the [Esc] cancel key can be pressed when the parameter
setting needs to be cancelled.
(1) [ROW, COL] is a group to adjust the output splicing mode.
You can confirm the value by viewing the OSD display
information in the upper left corner of the whole screen.
For example: if you need to adjust to 2x3 (two rows and three
columns) splicing mode, you need to set [row] to 2, and [COL]
to 3. Press [Ent] to confirm, and then the splicing mode will be
changed to 2x3.
(2) [Src, Win] is a group. The purpose is to arbitrarily specify
the input source channel of each screen (window) in the
"whole screen". You can confirm the value by viewing the OSD
display information in the "upper left corner of the whole
screen".
For example: Currently, it is [ ] PIP mode,HDMI is displayed

in large screen window and DP is displayed in small screen
window by default.If you need to adjust the large screen
window to DP and the small screen window to HDMI,Then
you need to set [Win] to “ 1 ” (window No. 1 means large
screen window), [Src] is “ 2 ” (2 means DP input) ， After
pressing the [Ent] confirmation key，The large screen window
can be switched to DP signal source.Set【Win】to“2”（window
No. 1 means small screen window），set【Src】to “1”（2 means
HDMI input），After pressing the [Ent] confirmation key，The
small screen window can be switched to HDMI signal source.
