How To Use

1. Please confirm from the AD-8541-SCALE product page that the weighing device to be used is compatible with this device.

2. Connect to the RS-232C connector (D-Sub 9 pin (male)) of the weighing device. Power is supplied from the weighing device. If the connector of the weighing device is D-Sub 25 pin or DIN 7 pin, a cable in “6. Accessories” is required.

3. Check that the monitoring LED lights up.
   If the LED does not light up, connect an AC adapter in “6. Accessories”.

4. The table below shows the relationship between monitoring LED colors, functions, and connectable devices.
   Press and hold the switch for several seconds to switch functions. Color| Functions| Connectable Devices
   ---|---|---
   Green| Bidirectional communication| AD-8541-PC
   (Wireless Communication Interface for PC) AD 8931 (Wireless Remote Display) Tablet / Smartphone 2
   Blue| HID 1| Tablet / Smartphone PC (Bluetooth-equipped)

*1:* HID over GATT Profile
2:** A dedicated app (A&D WeiV) is required.

5. Perform pairing from the other device. For the pairing method, refer to the instruction manual of the connectable device above. If a previously paired device is nearby, it will automatically connect, so when connecting to a new device, turn off or disconnect the unused device.
6. The monitoring LED blinks when wireless connection is established.

Bidirectional Communication Function

The monitoring LED lights green.
The same bidirectional communication as with a wired connection is possible.

• When connecting to an AD-8931, set the weighing device to stream mode.

HID Function (HID over GATT Profile)

The monitoring LED lights blue.
You can enter weighing values into a general-purpose text application (notepad or spreadsheet software) on your tablet or smartphone.

• Send the weighing data by pressing the Print key on the weighing device.
• The data to be entered is only numerical values, and headers such as “ST” and “WT”, signs of “+”, and units such as “g” and “kg” are not attached.

Pairing With Connected Device (Tablet / Smartphone)

With the Bluetooth function of the connected device turned on, turn on the power of the weighing device. From the Bluetooth connection of the connected device, select the device starting with “A&D_HID” and perform pairing.

• After 30 seconds have passed without pairing after selecting a device, the operation will time out. In that case, turn off the power to the weighing device and restart the operation.
• If you cannot reconnect with a device that has been paired in the past, delete the device information once and perform pairing again.

Keyboard Settings for Connected Devices

• If the input mode of the tablet or smartphone is a language other than English, poor reception or garbled characters may occur. Set the keyboard to English input keyboard (alphabet input mode) before connecting.
• If you need to install an English keyboard application, please refer to the A&D website for tablet or smartphone settings.
