UMG 104
m
RS232
You can use the connection cable (available
accessories) to connect the UMG104 to a PC.
The achievable distance between two devices
with RS232 interface depends on the cable
used and the baud rate. The maximum
connectable cable length is 30 m!
As a guideline value, for a transmission rate
of 9600 baud the distance should not exceed
15 m to 30 m.
The permissible ohmic load must be larger
than 3 kohm and the capacitive load caused
by the transmission cable must be smaller
than 2500 pF.
Interfaces
Shielding
A twisted-conductor and shielded cable must
be provided for connections via the RS232
interface. The shielding at both ends of the
cable must be connected to a large area of the
housing or cabinet parts in order to achieve an
adequate shielding effect.
Important!
Profibus, RS232, RS485 and
temperature measurement input are
not metallically separated from each
other.
All interfaces can be used simultane-
ously.
