then the DataView will continue to display the old values. Once the
communications port has become available the DataView will attempt to get

boxes where the numbers will usually be. For example:

then the DataView has not been programmed. This is the default message
when the DataView is sent out. A program needs to be sent to the unit. See
the program section for instructions.
PC294W does not get past the message Waiting for code from DataView…
Have you selected the correct communications port? Is the custom
programming cable properly connected?
PC294W displays the screen:
FIGURE 13. Incompatible File Type
A DLD program being downloaded from a datalogger usually causes this error
message. To use this DLD file, it must be loaded into Edlog using the
Document DLD function and subsequently recompiled. This file will not load
directly into PC294W because it does not contain any input location labels.
These are added during the documentation process.
