3 - 2 ba76037d01 01/2012
RS 232 The RS 232 interface cable is already connected to the terminal strip in
the factory.
SENSORNET All SENSORNET connections are identical and can be used as
required for extending/branching the cable section or for the connection
of sensors.
3.3 Connecting the MIQ/IF232 with the PC
Connect the interface cable of the MIQ/IF232 with the 9-pole connector
to any free RS 232/COM connection on the computer.
Note
The connecting cable between MIQ/IF232 and PC can be extended by
a 1:1 extension cable. However, a short cable is better for good EMC
characteristics. If the distances to the IQ S
ENSOR N ET system are long,
install the MIQ/IF232 in the vicinity of the PC so that no extension is
required. Bridge the distance to the IQ S
ENSOR N ET system with the
IQ S ENSOR N ET SNCIQ or SNCIQ/UG (distributed mounting) cable.
Note
Details for the installation of the software are given in the operating
manual on the IQ S
ENSOR N ET software pack.
