Change the corresponding program to receiving card, occupied information transmission bandwidth is a lot, cause to send snapping into the transmission of receiving card and need gigabit to pass
Send interface.
Receiving card receive come breath sending card transmitted by gigabit networking the video comprising address information, word, figure
Piece information, is previously written display unit module LED address information by the programmable gate array of receiving card, to distribute each
The information of unit module, the connected unit module of receiving card only limits a kind of specification and shape, is transferred to the number needed for unit module
More more than 16 according to line.
Existing LED display LED arrangement is lighted as unit using the constant-current driving that common cathode or common anode principle drive
Control, male or female is connected to power supply and is adjusted luminosity by constant-current driving by LED, and every constant-current driving is firmware electricity
Resistance adjustment constant current value, controls the output channel constant current value of IC by the every module unit of firmware resistance setting, and resistance setting needs foundation
Purchased LED luminosity presses 3：6：1 ratio calculates configuration, needs test to check and just can order in batches after the completion of configuration；Cell board
On LED arrangement information be to be stored on receiving card, need in advance cell board design complete connection system when make configuration information
Deposit file, need first to send configuration information to storage on receiving card after display screen installation, other parameters could be set；If
After the completion of putting, video information is assigned to receiving card and is assigned to the right of cell board by receiving card according to different positional information transmission again
Answer position.
