Installation
3.4 Connection
The DR 2800 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, 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 page 33) 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 6.7.2 on page 98).
