3 Equipment Use
3.1 Main menu introduction
splicing mode
The splicing mode function module contains 3 options: horizontal splicing, vertical splicing,
and field splicing. Select the appropriate mode according to the distribution of the loading area of
the sending card behind the LED screen.
Horizontal splicing: The 4 output ports of the stitcher are arranged horizontally and stitched
into a complete image.
Vertical splicing：The 4 output ports of the splicer are arranged vertically to stitch a complete
image。
Cross splicing splicing：The 4 output ports of the splicer are cross splicing into a complete
image.

Screen parameters
The screen parameter function module adjusts the load parameters of each of the 4 output ports
on the back of the splicer according to the load of the sending card. The four parameters OUT1,
OUT2, OUT3, OUT4 correspond to the four output ports respectively. For the number of the output
port, see the silk screen on the back of the splicer.

Screen layout
The screen layout function module contains four fixed layout templates. The layers opened
through the screen layout are fixed.
Layout one: Turn on a single layer, and one layer fills the entire screen.
Layout two: Turn on two layers. The layout of the layers is shown below. Layout three and
layout four are in analogy.

Output resolution
The output resolution function module can define the load and output frequency of the splicer
output port. The output resolution is divided into regular resolution and custom resolution. The
custom resolution is the output port size that can be defined according to specific needs when the
conventional resolution does not meet the conditions.

3.2 Layer information
There are two operations for turning on the layer: one is to press and hold the layer button for
3 seconds to turn on the corresponding layer. Another is to select the screen layout of the main
menu interface and turn on the layer by selecting the corresponding layout. The device turns on
the MAIN layer by default in the initial state. The layer setting interface contains all operations
specific to the layer.
