appears in the Actions pane detach the MiniProg.
4. Connect the bridge dongle through the USB port to the PC and wait for the bridge to enumerate.
When the dongle is first plugged in, the red LED turns ON. It turns OFF when the USB enumera-
tion process completes. Note that if the bind button is pushed when the dongle is first plugged in,
the firmware enters the MTK test mode and blinks the red and green LEDs alternately. The LED
blinks continuously until the dongle is removed from the computer.
5. After the bridge is enumerated as HID device in Device Manager, start using the bridge. To bind
the bridge with the mouse/keyboard, press the bind button on the bridge. The bridge then goes
into Bind Mode. In Bind Mode, the bridge uses the Bind ID to communicate with the mouse/key-
board to bind to the system.
6. The red LED blinks ON/OFF when the dongle is in Bind Mode. The ON and OFF time is approxi-
mately 320 ms, which is the rate at which the dongle changes channels during the Bind process.
7. The red LED also blinks ON/OFF when the PC is suspended. The blinking rate is approximately
1 second, which is the frequency of the wakeup interrupts.
8. The green LED turns ON when the dongle receives data from the mouse or keyboard. It remains
on for 250 ms after the last received data packet.
9. The green LED turns ON and remains ON if a key is pressed and held (because the keyboard
sends Keep Alive packets).
10.The green LED turns ON and remains ON during Ping Mode. In normal operation, Ping Mode is a
very short period. The user may not notice this period.
11. The red and green LED blink alternately in the Manufacturing Test mode.
