perfectly achieve seamless switching and high-definition image analysis conversion. It has
the function of preview edition, program output, switching transition, LOGO capture and
insertion and screen freezing, which can also realize variety of advanced functions
required in a high-end presentation environment.
DVX402 has a 4-channel fully configurable input, which can access 16 channels of
video input, including 4-channel DVI, 4-channel VGA, 4-channel VID and 4-channel
3G-SDI (optional), and each channel can receive SD or HD video signals.
DVX402 has 2-channel output, the main channel of which is the live program output,
and the vice channel of which is preview output. Program and preview output interface has
two DVI and one VGA, with the highest resolution up to 1920 x 1200 @ 60Hz or 2048 x
1152 @ 60Hz.
More Operating Layers: DVX402 has four layers, and a single output channel can
output three layers at most. Each layer has an independent parameter setting, and the user
can edit the position, size, color, LOGO of each layer. It has real-time save function that

Page 6 of 55
DVX402 has rich input and output interfaces, which can switch in VGA and DVI
signal of desktop computer, laptop, SDI (optional) signal of high-definition camera, and
DV and DVD video signal. Both the outputs of preview and program have two DVI
interface and a VGA interface, which can meet the various needs of users.
DVX402 has two-channel outputs, one channel can be connected to preview display;
and the other channel can be connected to the projector or LED video wall. After editing
images after the preview display, the user can follow the switch or exchange the switch
to the video wall. If the user needs to connect the LED video wall, it can be connected to
LED video processor, and then output it to the LED video wall. Program output of
DVX402 can also be connected to the LED video processor or LED video splicing
processor, and the switch does not need to zoom the image and the DVI output of the
program is directly connected to the video processor. If necessary, the user can use the
software or the console to have full control on DVX402.
Installation
Install DVX402
The user can choose whether to install DVX402 to rack or flight case. DVX402 is a
standard 2U chassis, with the size of 8.8cm (Height) x 44cm (Width) x 33.5CM (Depth).
While installing, please avoid scratching the case and use cushion for fixing suspension
loop.

① # 1 ~ # 4 Channel Video Input
It can receive a 4-channel video at the same time, and each channel can receive VGA,
DVI, HDMI (DVI terminal), VID (CVBS) and SDI (optional). DVX402 offers a number
Page 8 of 55
of input interfaces which can connect 16-channel video. After a one-time access, the user
can quickly switch video source without reconnection.
The following are the corresponding terminals for the input interfaces:
DVI input - DVI-D
VGA input - DB15
SDI input (optional) - BNC
VID input - BNC
Figure 2-3 DVX402 Channel # 1 Input Interface
②③ Communication Interface
② TCP / IP interface, using RJ-45 terminal, is reserved for the communication interface.
③ RS-232 interface, using DB9 terminal if it is connected by computer’s RS-232 or
console, resolution adjustment, channel selection and seamless switch to DVX402 can be
operated by it.
④ Preview Video Output Interface
Preview output is normally connected to the preview display. There are two video
output interface in the preview channel, and has two DVI-I seats, of which DVI / VGA
interface can output DVI and VGA signal. When using VGA output, DVI-VGA adapter
Page 9 of 55
need to be connected to the DVI / VGA interface. The video image and resolution
outputted by the two interfaces are the same, which can be switched in multiple monitors;
therefore, both the operator and the commander can see the switching picture.
Figure 2-4 DVX402 Preview Output Interface
⑤ Program Video Output Interface
The program output channel has two video output interface, using two DVI-I
terminals, of which DVI / VGA interface can output DVI and VGA signal. When using
VGA output, DVI-VGA adapter need to be connected to the DVI / VGA interface. The
video image and resolution outputted by the two interfaces are the same. Normally, DVI is
outputted to the LED sending card or projector. The interface output resolution can change
by itself, with the resolution output up to 2048 x 1152.

⑥ ⑦ AC Power Connector and AC Switch
Page 10 of 55
DVX402 provides a standard IEC power terminal with the input power of 100 ~
240VAC, 50Hz or 60Hz, at the same time, the ground wire of the power supply must be
grounded to avoid equipment damage or the electric shock to human body.
Operation Interface
All the control and instruction of the switcher are set on the front panel (see Figure
3-1). These keys provide yellow and green background lights, which indicate the current
input selection and layer selection. The user can re-paste the character or graphic label on
the program and preview input selective keys (1, 2, 3, and 4). A 240×64 LCD window
indicates the current state of the seamless switcher, menu selection, data status, and other
system parameters.

Mix Layer Split: layer A and layer B is called superimposed layer, whose separation
means whether layer A and layer B can be allowed to appear in the same screen (preview
or program).
Open Mix Layer Split: key A and Key B can be used separately. The channel of
program or preview can output at most three layers, which enlarge the degrees of freedom
used by the user and at the same time may create conflict layers (such as, the preview and
program in the same layer). When adding layer in the preview, it may add the same layer
with the program. As shown in Figure 4-9, the preview and program are both in layer A
and layer B.
Close Mix Layer Split: press key A and Key B in the key panel, and then key A and
Key B will show the yellow light. At this time, key A and Key B can be taken as the only
one key, and the corresponding layer is on the top of the current preview display, as shown
in Figure 4-10.
Page 25 of 55
Tip: Close Mix Layer Split will avoid adding the same layer in the current program of
the preview display, and totally avoid the impact that the background operation makes on
program.

Open Modify On Program: when it is open, all the keys in PROGRAM information
source key area can be used. The adjustment of layer input source, window size and
position, crop size and position can be changed on program output.
Close Modify On Program: when it is closed, all the keys in PROGRAM
information source key area cannot be used. The adjustment of layer input source, window
size and position, crop size and position cannot be changed on program output.
When the layer in the preview is the same with the layer in the program, if the size
and position of the preview layer is adjusted, the layer on the program will also change in
the same way, as shown in Figure 4-11.
