4. Device Debugging
4.1 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,
method: signal source (e.g.: computer)
→
Mosaic Processor
→
LCD.
Control connection:
connect control computer with device control port and debug device
connection method. There are three connection methods
(1) Connect 100MB network control port with splicer LAN(100M) port, which can set device
software
(2) Connect computer gigabit network port with splicer LAN(1000M) 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 kind of method among the
three can realize device software control.
