Troubleshooting
Serial interface (USB, RS232): The data logger is not recognised during "
Test
" of
Winsol
.
1.
Ensure that the data logger is connected to the PC via a USB connection.
2.
If no controller is connected to the D-LOGG, then its slide switch must be in the "USB"
position.
3.
Check in the Windows
Device Manager
whether the USB driver has been correctly in-
stalled (Device Manager
Ports (COM and LPT)). In this case, its virtual COM port
appears in the list as "USB Serial Port".
3.1.
If the driver has not yet been correctly installed, carry out the installation again
(see Chapter "
USB driver \ Installation
").
4.
If the data logger is provided with at least one controller, check the data transfer from
the controller to the data logger (
see the next point
).
Data transfer from the controller to the data logger is not working.
(No measured values are displayed in the "
Current measured values
" of
Winsol
.)
1.
Make sure that the data logger is connected to the controller and the slide switch is in
the "DL" position.
2.
Check the connections and in particular ensure the polarity is correct.
3.
With the UVR1611, data output must be activated if logging over the data link (DL-bus)
is to take place (output 14 defined as "
data link
"). On controller UVR16x2, data output
must be enabled in “DL settings” in the menu “DL bus”.
4.
If several controllers are recorded using the data logger, check the data connections
individually to limit the problem. To do this, connect the data link (DL-bus) or CAN bus
as appropriate to the other controllers. When doing so it is important that the data link
is connected directly to the controller and not to the data input of the data logger, as
otherwise you will not receive useful results!
4.1.
If data transfer functions over the DL-bus with each controller individually, then
the cause of the error is crosstalk between the two data links of the DL-bus. In
this case the two data links must be routed separately or at least one data link
must be routed in a shielded cable.
5.
To limit the cause of the error during data transfer to a single data link, carry this out
as a test over a short cable (< 1 metre).
5.1.
If data transfer functions over the short cable, then the error cause could be
crosstalk caused by an external interference source in the data link (DL-bus). In
this case, the data link must be routed in another way or a shielded cable must be
used.
6.
If, in spite of the testing of all listed points, incorrect behaviour still exists, please con-
tact your dealer or contact the manufacturer directly. However the cause of the fault
can only be found if a
precise description of the fault
is provided!
