3. Function Description
3.1
Block Diagram
Figure 3-1:GL911Tx Block Diagram
3.2
Power supply
GL911Tx‘s operation voltage is between 2.2V to 5.0V. It is recommended to use DC-DC step up
converter to provide a stable 3.0V for GL911Tx MCU, IR Emitter LED and analog photo sensors. It is
possible to reduce the DC-DC step up converter circuit, if using the digital photo sensors.
3.3
Resonator for oscillator
GL911Tx has been optimized for its firmware code. It uses only 2Mhz resonator to operate 4800 Bps
encoding and mouse control sequence. Lower resonator frequency means lower power consumption
and longer battery operation life.
3.4
Reset & Setup Button
Each mouse needs a unique Random ID to avoid co-channel interference between two or more closer
device working at the same time. Press “Setup” button can change the Random ID at each time.
The “Setup” button and the MCU “reset” pin is the same pin (Active Low). Pull up resistor (30K~100K
ohm) is required for this pin. When the setup button is pressed (change from Low to High) GL911Tx
will generate a new 8 bits ID with random number and enter “Broadcast mode” 30 seconds. If the
receiver (GL901Rx) is also in the “Setup” phase
(Note1)
, receiver will accept the packet and store the
Random ID into EEPROM.
Note1
: The receiver will keep listening the broadcast packet 30 seconds after the receiver “Setup”
button is pressed or “Remote Setup” is enabled. Please refer to the GL901Rx datasheet.
