Serial interfaces
The UMG96S can have up to three serial inter-
faces, depending on the different available ver-
sion.
Profibus DP
RS232
RS485
These serial interfaces are not separated gal-
vanically. The RS232 and RS485 interface can-
not be used at the same time.
The Profibus interface can be operated at the
same time with RS232 or RS485 interface.
Automatic recognition of the interface
If both interfaces are connected, the UMG96S
recognizes by the signals, if a device is con-
nected at RS232. The data transmission is car-
ried out via RS232.
If no device is recognized at RS232, the data
transmission is carried out via RS485 interface.
Interface selection (Addr. 062)
The selection of the RS232 and RS485 inter-
face is carried out on address 062:
0 = Automatic recognition
1 = RS232
2 = RS485
Modem operation (Addr. 070)
Via RS232 or RS485 interface, the UMG96S
can be connected to an analogue modem. To
enable the UMG96S to transmit data via an
analogue modem, address 070 must be
overwritten with the value 1.
Address 070 = 0 => Modem operation = No
Address 070 = 1 => Modem operation = Yes
The connection between RS232 interface and
analogue modem is done by a modem cable
(option). The modem cable, part no. 08.01.503,
does not belong to the contents of delivery of
the RS232 interface.

Device address (Addr. 000)
If several devices are connected via RS485 or
Profibus interface, the master (PC or PLC) can
tell those devices by their device address only.
Within a network, each device UMG96S must
have its own device address.
Up to 255 device addresses can be entered.
Baud rate (Addr. 001)
For RS232 and RS485 interface, the following
common baud rate can be set.
Baud rate
: 0 - 9.6kBit/s
1 - 19.2kBit/s
2 - 38.4kBit/s
