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

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.

4. Common problems
(1) What is the output resolution of the loop-out interface?
Answer: if the input interface of the device is 3840x2160 resolution, the ring out DP

深圳市比特视讯有限公司
第18 页 共 19 页
interface resolution is 3840x2160 resolution.
(2) Does it support cascading mode?
Answer: cascade mode is not supported.
(3) Sometimes the dial code or remote control switch does not respond?
Answer: Because it involves resolution switching, it takes a certain time (1s). If the
display does not meet the expectations, it can be restored by power off again.
(4) Image rotation, image does not rotate, is there the simplest way to remember
the number of output screen?
Answer: yes , we have.The number follows "from top to bottom, left to right",it's
just that your head looks at the image 90 degrees to the right.Rotation and non
rotation of BIT-V406R, only 3 cases. (1 No rotation); (2 rotation 90 °);(3 rotation
180 °).
5. Appendix
