Installation
3.3 Power connections
Only the provided external power supply LZV798 has to be used.
Install the correct adapter plug on the supplied external power
supply (
Figure 1
) by sliding the adapter on until it "clicks" into
position. Correctly mounted, both housing of power supply and plug
are in line. Plug the external power supply cord into the connector
on the back panel of the instrument, then plug the supply into a
power outlet (100–240 V~ / 50–60 Hz). Press the power switch on
the back of the instrument to initialize power.
3.4 Connection
The DR 2800 has two USB interfaces as a standard feature,
located on the back of the instrument (
Figure 1
).
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
).
