Campbell Scientific CD294 DataView Dual Line Data Display - Manual (Page 10)

DataView (CD294) Dual Line Data Display
Once you are ready to send the data to the LCD click on the Write to LCD
button. This will bring up the window shown in FIGURE 11.
FIGURE 11. Communication Options
The only option to select in this window is the COM port. At this stage you
can plug the DataView into the desired COM port using the custom
programming cable supplied. Click on the Start Comms button to begin
transferring the data.
When the Start Comms button is pressed the program actually writes the LCD
file to disk, along with the information about the first 255 input locations and
the execution interval. The name of this file is the same as the DLD except
with LCD for the extension. This all occurs in the background before the data
is sent to the DataView.
FIGURE 12. Waiting for Acknowledge
Once communications has begun, the program will wait for the DataView to
return an acknowledge code and will then begin transferring the data.
When data transfer is complete, the DataView configuration is complete. The
custom programming cable can now be removed from both the computer and
the DataView. It will not be required unless you wish to reprogram the
DataView at a later date.
Store the custom programming cable in a safe place. This is a
custom cable and cannot be purchased other than through an
authorized Campbell Scientific distributor. Loss of this cable
could result in prolonged delays while waiting for a replacement.
Should a replacement be required, order part # SC294 from your
authorized Campbell Scientific distributor. NOTE
