➲
Connect to the DT800 using
dt800 Com1
.
To do this…
a) In DeLogger’s Connections menu (fourth from the
left), choose
Connect…
.
b) In the Connect dialog box that opens, highlight (one
click)
dt800 Com1
and click
OK
.
Two progress bar dialog boxes open, then close
automatically to indicate that you’ve successfully
connected to the DT800.
If a dialog box opens asking if you want to upgrade
to a later version of the
dataTaker firmware, click
No
. (You can do this at another time.)
If DeLogger is unable to connect (you’ll see an
“Error connecting to…” message), go to the Extras
panel “Connection Troubleshooting”.

Now carry out some simple communication with the
DT800.
➲
Get the
dataTaker’s status.
To do this…
a) From DeLogger’s
dataTaker menu (sixth from the
left), choose
Status…
.
DeLogger communicates with the DT800, retrieves
information about what’s currently happening in the
DT800, and presents the information to you in the
large dialog box that opens (Figure 15).
You can do this anytime you’re connected to a
DT800. In fact, as well as using this command to
find out which schedules (see page 33) and alarms
(see page 63) are currently running in the DT800,
how much data storage (memory) is used and free
in the DT800 and so on, you can send this
command simply to confirm that you’re connected
to the DT800.
b) Look through the Status dialog box tabs to
familiarize yourself with the information you can get
from it, then click
OK
.
Flow Control
Flow control is a communications feature that allows
communicating devices to control each other’s
transmission of information.
DeLogger and the DT800 support two types of flow
control:
•
Hardware Flow Control (HWFC)
Flow control
signals are sent between the communicating
devices by means of RTS and CTS control wires in
the cable.
•
Software Flow Control (SWFC)
Flow control
commands XOFF and XON are sent between the
communicating devices by means of the
data wires in the cable.
Setting Flow Control
You must set the same
type of flow control at each end of a
communications link. For example, for this tutorial,
both the DT800 and your DeLogger Connection
must be set for software flow control.
This Tutorial
We recommend that you use
software
flow control for this tutorial. This is the
default/factory setting for a new DT800 and for
DeLogger’s
dt800 Com1
Connection. (If you’re using
a DT800 that has previously been set to hardware
flow control, you must either change the DeLogger
Connection to hardware flow control also, or change
the DT800 to software flow control.)
