Serial interfaces
Depending on the version the UMG96S may
have up to three serial interfaces. The serial in-
terfaces are not separated galvanically.
The RS232 and RS485
cannot
be operated at
the same time!
If both interfaces are connected, the device rec-
ognizes by the signal level, if an instrument is
connected to the RS232. The data transmission
is carried out via RS232 only.
If no device is recognized at RS232, data trans-
mission is active on RS485 interface.

Inputs and outputs
The UMG96S offers the possibility of assigning
different functions to the outputs of the different
versions (options).
Terminal 12, for example, can have the function
"pulse output" and terminal 13 can have the
function "digital input". Please note, that both
circuits have a common 24VDC, termi-
nal 11.
Only one function can be assigned to each ter-
minal 12 and 13.

Attention!
Real energy Wp is firmly assigned to
puls output 1.
Reactive energy Wq is firmly assigned to
puls output 2.

Diagr.: UMG 96S with one analogue and one
digital output as pulse output for real energy.
The cable for serial data transmission
must be performed in a shielded way, if
the cable length is more but 30m or the
cable leaves a building.
