.
EEPROM
Store the system information for user friendly.
. Flash Memory
System software was stored in this chip, which the memory size is 4M bits.
. Remote Mouse
The DX760 support remote USB mouse, there is one USB B-type connector on DX760
MBD. The chip IC801 support USB mouse, there is hardware setting to ensure it should be
working, whenever the chip receives the IR signal from receiver, the chip will respond to the IR
signal and sending out to PC the according simulated mouse code hence control the mouse
movement and function.
.IR Receiver
The PIC-26043LM is miniaturized receivers for infrared remove control systems. PIN diode
and pre- amplifier are assembled on lead frame, the epoxy package is designed as IR filter. The
demodulated output signal can directly be decoded by a microprocessor. The main benefit is the
reliable function even in disturbed ambient and the protection against uncontrolled output pulses.
