The DR 2800 has two USB interfaces as a standard feature,
located on the back of the instrument (

The USB Type A interface is used for communications with a
printer, USB memory stick, barcode scanner, or keyboard. A USB
memory stick is used to update instrument software.
The USB Type B interface is used for communications with a PC.
The optional Hach Data Trans software (see
section 5.2.6.3 on

A USB hub may be used to connect several accessories at a time.
Note: USB cables must not be longer than 3 meters (10 feet).
These USB interfaces enable data and graphics to be output to a
Printer and a PC and upgrade instrument software (see
