SERIAL

INTERFACE

AND

USB

The HD3406.2 is fitted with an electrically isolated RS-232C and USB2.0 serial interface.
The USB connection requires the previous installation of a driver in the instrument software. Install
the driver

before connecting the USB cable to the PC

(please see the details on page. 32).

The instrument standard serial transmission parameters are:

•

Baud rate 38400 baud

•

Parity

None

•

N. bit

8

•

Stop bit

1

•

Protocol

Xon/Xoff

It is possible to change the RS232C serial port baud rate by setting the "

Baudrate

" parameter in the

menu (please see page 9). The possible values are: 38400, 19200, 9600, 4800, 2400, 1200. The
other transmission parameters are fixed.
The USB 2.0 connection does not require the setting of parameters.

The instruments are provided with a complete set of commands and data queries to be sent via the
PC.

All the commands transferred to the instrument must have the following structure:

XYcr

where:

XY

is the command code and

cr

is the Carriage Return (ASCII 0D)
