Getting Started with DT800
dataTaker
UM-0071-A0
DeLogger or DeLogger Pro to plot graphs of your data
versus time directly on the computer screen.
Communication
The most common method of supervising your DT800
is to send commands to it directly from a computer.
(There are other methods — see the Extras panel
“Sending Commands” on page 8.)
To do this, and for the DT800 to return data to the
computer,
• your computer must be running one of
dataTaker’s
DT800-friendly software packages such as
DeLogger, DeLogger Pro, or DeTransfer
• the computer’s communications port must be
connected to one of the DT800’s communications
ports by any of the methods described in the Extras
panel “Communications Links”.
Power
You can power the DT800 from three sources:
A mains adaptor and 12 volt internal battery are
supplied with your DT800. This 12V battery is known
as the
internal main battery
to distinguish it from the
DT800’s other internal battery, the
internal memory-
backup battery
(next topic).
NOTE
The DT800 is shipped with its internal main
battery disconnected. Although you don’t need it to
work through this user’s guide (because we instruct you
to power the logger from its mains adaptor), it’s a
good idea to connect the internal main battery in the
near future so that it can be fully charged — see “Main
Battery is Disconnected for Shipping” in Part C of the
DT800 dataTaker User’s Manual supplied with your
DT800.
Good Power Practice
The recommended method of working with the DT800
is — while you are programming it “back at base” —
to power it from the mains using a mains adaptor. The
mains adaptor supplies the logger and charges the
main internal battery.
When you’ve finished programming and are ready to
use the logger “in the field”, you disconnect it from
both the computer and the mains adaptor and it
continues to operate from the freshly-charged main
battery. The amount of power consumed by the DT800
depends on the program running.
Communications Links
With appropriate software, the DT800 and the host
computer can communicate with each other by
means of
• a communications cable (called a “direct”
connection) — for distances of up to 50 meters / 55
yards (a
dataTaker communications cable, product
code IBM-6, is supplied with your DT800)
• a communications cable fitted with line drivers —
for distances of up to 5000 meters / 5500 yards
• telephone or radio modems, or satellite links — for
much longer distances (you’ll need to upgrade to
DeLogger Pro if you want to use modems)
• an Ethernet network — the DT800 supports
10BaseT Ethernet.
