Installation
3.5 Interfaces
The DR 3900 features three USB ports and one Ethernet port as
standard, located on the front and rear sides of the instrument
(Figure 1 and Figure 2, page 17).
The USB type A ports are used for communications with a printer,
USB memory stick or keyboard. A USB memory stick can be
used to update the instrument software.
The USB type B port is used for communications with a PC. The
optional Hach Data Trans software (refer to Section 9, page 137)
must be installed on the PC for data transfer.
A USB hub may be used to connect several accessories at a
time.
Note: USB cables must not be longer than 3m.
These USB ports permit data to be exported to a printer or PC
and also allow the instrument software to be upgraded (refer to
section 6.8.2, page 111). The Ethernet port supports real-time
data transfer in local networks, LIMS systems or SC controllers.
Only use a shielded cable (e.g. STP, FTP, S/FTP) with a
maximum length of 20 m for the Ethernet port.
