Hardware / General information
Power Supply / Slide Switch
When the data converter is connected to at least one controller (DL), the slide switch on the
converter must be in the "DL" position (left) !! Otherwise, problems with data logging can
occur. The data converter receives the power it requires from the controller, regardless of
whether it is connected to a PC or not.
Bus load (DL-bus) = 24%
If the data converter is not connected to any controller, the slide switch for communication
with the PC must be in the "USB" position (to the right) , so that the converter is supplied
with power via the USB connector.
The recorded data is saved to internal memory every hour, where it is retained even when no
power is present. This means that a power loss will result in a maximum loss of the last hour
of data.
Data line
Every UVR controller has a data line output DL (with the EEG30, TFM66

D0) that, together
with the (sensor) ground conductor, forms a two-conductor cable. The data converter has 2
data line inputs for simultaneously recording measured values from up to two controllers.
Connection 1 controller:
Controller D-LOGG
Connection 2 controllers :
Controller 1 D-LOGG Controller 2
Any cable with a cross section of 0.75 mm² can be used for the data link (e.g. twin-strand)
having a max. length of 30 m. For longer cables, we recommend the use of shielded cable. If
the data from two controllers is to be acquired by the data converter, then separate shielded
cables must be used to provide protection against crosstalk errors. The data conductors must
never be in the same cable as the CAN bus.
