equipment through the upper computer software.
3. Device Debugging
3.1 Device Connection
Device connection could be divided into three parts: power connection, signal
connection and control connection (used for software debugging).
Power connection: device power supply. Connection method: connect power
cord to power plug.
Signal connection: the method transferring signal from signal source to LED
large screen. Connection method:
signal source→(e.g.: computer)Splicing Processor→Sending card→Large
screen.
Control connection: connect computer with device control port and debug device
connection method. There are three connection methods:
（
1
）
Connect 100 mbit network control port with splicer LAN1 port, which can
set device software.
（
2
）
Connect computer gigabit network port with splicer LAN2 port, which can
not only set device but also echo signal source image.
（
3
）
Connect one crystal head of serial port line which is randomly donated by
device with splicer COM port, and plug DB9 into computer serial port. Any of the
three methods realizes device software control.
