To connect your Essae AX Series balance to a PC or peripheral device, you must use a standard 6-pin Mini-DIN connector on the balance side, wired to a 9-pin 'D' Type (DB9) connector on the computer side.

Data Transfer Modes:
The balance supports multiple data transfer protocols configured via parameter "C11 LSD":
- Stream Mode (Continuous output)
- Manual Mode (Transmits only when the [*] key is pressed)
- Command Mode (Transmits when "CTRL+E" or "W" is received from the PC software)
- Auto Weight Transfer (Transmits automatically once a stable weight is locked)

Communication Parameters:
Default baud rates and parity can be configured under customer specification "C10". Supported speeds include 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200. Ensure your PC software matches the scale's baud rate exactly. Note: Any changes to RS232 settings require a power cycle (OFF/ON) to take effect.
