Figure 1: Front Panel of PDU. (A) Charge LED, (B) USB-C Port, (C) RX LED, (D) TX LED, (E) Bluetooth LED, (F) Power Button, (G) SAA Power On LED, (H) Battery Gauge LED
Charge LED (red):
- If the Charge LED is solid on, the battery is charging.
- If the Charge LED is off, the battery is fully charged or is not charging/not plugged in.
- If the Charge LED is blinking (0.5 Hz), the battery cannot be charged or is already fully charged. Move the PDU to a room temperature location for charging.
RX LED (green):
- Array data (blinks as data goes by).
TX LED (red):
- Commands data (blinks as data comes in from SAARecorder).
Bluetooth LED (blue):
- If the Bluetooth LED is blinking, the Bluetooth connection has not yet been established.
- If the Bluetooth LED is solid on, the Bluetooth connection has been made and communication has been established.
Power Button LED (green):
- If the Power Button LED is solid on, the PDU is running.
- If the Power Button LED is off, the PDU is in sleep mode.
SAA Power On LED (red):
- If the SAA Power On LED is solid on, power is turned on to the ShapeArray.
Battery Guage LEDs (green):
- If all three LEDs are lit, the PDU is fully charged and does not need to be plugged in to charge. If plugged in, the charge LED may flash, but if already fully charged, the PDU does not need to be plugged in.
- If the first two LEDs are lit, the PDU is 50% charged.
- If the first LED is lit, the PDU is 25% charged.
- If the first LED is slowly blinking (5 Hz), the PDU is 10% charged.
- If the first LED is quickly blinking (10 Hz), the PDU is less than 10% charged.
