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 theother 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 thevideo 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

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 9 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
②TCP / IP interface, using RJ-45 terminal, is reserved for the communication interface.
③RS-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.
④Preview 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 canoutput DVI and VGA signal. When using VGA output, DVI-VGA adapter

Page 10 of 55
need tobe 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 theoperator and the commander can see the switching picture.
Figure 2-4 DVX402 Preview Output Interface
⑤Program 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.

⑥⑦AC Power Connectorand AC Switch

Page 11 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.

①FREEZE: Screen Freeze Key
There is FREEZE key in PROGRAMand PREVIEW key area, which can lock the
currently selected input picture and show it to the program output or preview output. When
FREEZE key is working, thekey shows green light, and all the input keys (1~4 key) will
be shielded. But if the user presses the key again or selects other input, the frozen frame
will be canceled.

②Input Selection Key
These two groups of INPUT # 1～# 4 are to choose input source and then output to
the program or preview display. When the input channel is selected, the key will show
yellow light. DVX402 will record every input video data, such as, layer position, size,
brightness, crop mode.
③LOGO / BLACK Key
There is LOGO / BLACK key separately in PROGRAM and PREVIEW key area,
which can output the stored logo or black to the preview output or program. It is first
edited in preview display and then itwould be switched into program output. When press
LOGO / BLACK key, the key will flash yellow light, and all input key (1to 4 key) in the
current layer will be masked, until the user presses the key again to cancel LOGO /
BLACK function.
④CUT Key
Pressing the CUT key can make the current preview image directly switch into the
program output, without any additional transition effects.
