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. 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.
  • 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.
