S2U Serial TTL to USB-A Adapter Kit
Use this serial TTL to USB-A adapter (USB dongle) to connect our digital load cells and load cell interfaces to a PC's USB port. When connected the device shows up as a virtual COM port and once can communicate with device via terminal emulator programs such as Hypeterminal, TeraTerm etc.
The following products need the adapter to communicate with a PC running Windows XP, Windows Vista or Windows 7 or Linux or MacOS operating systems. The base output of these devices is Serial TTL (Serial) and the USBA adapter converts the signal into a USB signal:
- iLoad Series USB Load Cells
- DQ-1000U Capacitive Load Cell Interface
- DQ-4000/DS-4000 Load Cell Interfaces/Load Cell Indicator
- DI-100U USB Load Cell Interface

USBA adapter, shown, attached to a cable with mini B connector coming from a device such as the DI-100U or the iLoad series load cells.

If you would like access to the Serial TTL pins coming from or to the USBA adapter, you can take a look at our HX-100 breakout board.
PLEASE NOTE this is a proprietary adapter designed for use with Loadstar Sensors products only. Do not substitute with other adapters since this might damage your load cells.
