Installation
3.4 Interfaces
The DR 3800 has two USB interfaces as a standard feature,
located on the back of the instrument (
Figure 2 ). The USB Type A
interface is used for communications with a printer, USB memory
stick 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 9 on
page 131 ) must be installed on the PC for this use.
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
section 6.8.2 on page 110 ).
