Features

Enables A&D balances/scales with an RS-232C (D-Sub 9-pin) interface to wirelessly communicate with a Bluetooth-equipped device such as a smartphone/tablet, PC, or the AD-8931 remote display.

Maximum communication distance: 10 m (line of sight).

Eliminates spacing/cabling problems and risk of contamination in places such as fume hoods, safety enclosures and glove boxes.

Can be used without a separate power supply as it receives power from the connected balance/scale (except for some models).

HID^*1 function: Capable of sending weighing data directly to general-purpose text apps such as notepad and spreadsheet.

Also allows bi-directional communication with freeware such as A&D WeiV on a smartphone/tablet or WinCT on a PC^*2.

*1 HID over GATT Profile
*2 For bi-directional communication with a PC, a separately-sold dongle, AD-8541-PC, is required.
