THE
DT800
There are several ways of providing power to your
DT800, which are covered in “Powering the DT800”
in Part C of the
DT800 dataTaker User’s Manual. In
particular, be sure to read “Main Battery is
Disconnected for Shipping”.
For this tutorial, you’ll simply use the mains adaptor.
➲
Provide external power to the DT800 using
the mains adaptor supplied.
To do this…
a) Plug the coaxial connector of the mains adaptor into
the coaxial
11–28Vdc
socket on the left side of the
DT800.
b) Plug the mains adaptor into a wall outlet and, while
watching the DT800’s front panel, switch on at the
wall.
If the DT800’s internal main battery is not connected
(we’re assuming yours is not), the five red LED (light-
emitting diode) indicators on the front panel flash
rapidly four times. Then the Acquiring LED begins its
“heartbeat” flash — every three seconds. (The
functions of these LEDs are described in “Indicator
LEDs” in Part B of the
DT800 dataTaker User’s
Manual supplied with your DT800.)

For the computer to talk to the DT800, and the DT800
to return data to the computer, you must establish a
communications link between the two.
You can use any of the links described in the Extras
panel “Communications Links”, but in this guide we’ll
use the simplest of all, the comms cable supplied with
the DT800. You’ll connect it between the DT800’s Host
RS-232 port and a COM port on your computer.
➲
Locate and identify your computer’s COM1
serial port then connect the comms cable to it.
To do this…
a) On the rear of your computer, locate the COM1
port and remove anything plugged into it (a
modem, for example).
If you find several likely connectors and don’t know
which is COM1, just choose any one. Later, if
communication with the DT800 is unsuccessful,
simply change to a different connector (we’ll remind
you about this in the next chapter).
b) Plug either end of the comms cable supplied with
the DT800 into the computer’s COM1 port.
➲
Connect the comms cable to the DT800.
To do this…
a) On the left side panel of the DT800, plug the other
end of the comms cable into the connector labelled
Host RS-232
