5.2.3Schematics

The PRoC LP RDK bridge schematics and Gerber files are located in the following directory: <installation directory>\Hardware\Bridge. The schematic is in Adobe Acrobat PDF for- mat with the letters ‘Sch’ in the file name.

5.2.4LED Usage

Red LED:

■The red LED blinks ON/OFF when the bridge is in Bind mode. The ON and OFF time is approxi- mately 320 ms which is the rate at which the bridge changes channels during the Bind process.

■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 wake up interrupts.

Green LED:

■The green LED turns on when the bridge receives data from the mouse or keyboard. It remains on for 250 ms since the last received Data packet.

■The green LED turns on and remains on if a key is pressed and held (due to the keyboard’s send- ing Keep Alive packets).

■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).

The Red and Green LED are blinking alternately when in Manufacturing Test mode.
