Why the AT10PB always shut down when using a power bank ?

The AT10PB Cash Drawer Trigger is a low-power consumption device and draws minimal current. Some portable power banks automatically disable output if they detect very low current — mistakenly assuming no device is connected. This may cause unexpected power shutdowns.

🛠️ Solution Options

• Use a standard power adapter
• Use a power bank with “Always-On” mode — designed to keep output active even under low current draw
• Upgrade to AT10M3 Cash Drawer Trigger :

  • AT10M3 Power Compatibility Statement

    • The AT10M3 Cash Drawer Trigger supports DC5V input, making it fully compatible with standard USB power adapters and portable power banks.
    • It also supports online charging, allowing continuous operation while connected to a power source — including mobile power banks.

10PB LED Status Guide & Troubleshooting

 A. Normal Operation

• 🟢 Green LED (2) ON: Power is connected and ready
• 🔴 Red LED (4) ON: Trigger signal is active

 B. Both LEDs OFF

If neither LED is lit:

Action Steps:

• Plug in the USB power cable using a DC 5V USB power adapter
• Verify that both the USB cable and adapter are functioning properly
• If everything checks out but the LEDs remain off, the 10PB unit may be faulty → Please return it to the factory for inspection

🟢🔴 C. Both Green & Red LEDs ON

🧪 Troubleshooting Steps:

1. Disconnect the USB power cable (Port 1) and RJ cable (Port 3)
2. Reconnect the USB power cable and observe LED behavior

🔴 Red LED Behavior:

• Flashes once when button is pressed → Check the cash drawer and its cable → This test confirms drawer status; an open drawer may trigger the flash. Flashes once when the button is pressed again; the USB power cable needs to be disconnected
• Stays solid (no flash) → Disconnect USB power for 30 seconds, then reconnect → If issue persists, the 10PB may be damaged → Return to factory for inspection
• Does not light at all → If Green LED is ON but Red LED remains OFF → Likely a hardware fault — return to factory for repair

T10U3 Cash Drawer Trigger cannot detect cash drawer open/close status ?

Common Reasons & Fixes :

A. Cash Drawer Lacks a Sensor

• Not all cash drawers have built-in sensors to detect open/close status.
  Solution: Confirm with the manufacturer whether your drawer supports status detection via RJ11/RJ12 pins (typically pins 3 & 6).
• Trigger Model Doesn’t Support Status Detection , Please check cash drawer sensor type.

B. Incorrect Sensor Type Configuration : 

       Cash drawers use either:

• Normal Open (NO): Sensor circuit is open when drawer is closed.
• Normal Close (NC): Sensor circuit is closed when drawer is closed.

C. POS Software Doesn’t Poll Status : 

• Your POS system must actively check the COM port for status return codes.
  Solution: Integrate status polling in your POS software.
