Connecting PC-Tool to the bus system !
In bus mode no tools may be operated through the
communications socket of the NMV-
D2M. For this
application the connection is made directly to the
UK24LON unit or the DDC system.
!
Duplicated NMV-D2M power supply !
The NMV-
D2M must not have a duplicated power
supply! When using this method of connection re-
move the AC 24 V plug from the ZIP-RS232 unit.
!
Detailed information about the MP-bus interface
ZIP-RS232 can be found in the data sheet ZIP-RS232.
