Are the MPI-200 and the sensor con-

The program should automatically de-
tect that a device has been connected
or disconnected. If not, this function
can be manually activated.
If the USB connection was detected by
the operating system, the COM no. ap-

"Uart:" ?
If the USB driver was correctly in-

Device Manager.
Is an external power supply is con-
nected to the M12 connector of the
MPI or is the "Power supply MPI-200"
parameter set to "PC"?
Is .NET 4.0 or higher installed on the
PC?
Was the MPI-200 connected just
before the program was started?

Solution
Check the cabling.
Clicking on the "Reconnect" button
prompts the program to read in the
device structure again.
Disconnect the USB cable from the PC
and reconnect it.
If the system asks for a manufacturer
CD, please insert the supplied CD
and specify the "FTDI" path of the CD
drive.
Set the appropriate power supply.
Install .NET from the supplied CD,
path "NET4.0".
Start the program before connecting
the MPI-200 or wait until the operat-
ing system has detected the USB
device.
Set the mode to the required ap-
plication. Depending on the setting,
certain modes may be password
protected.
In a later software version, it will
also be possible to save and load the
parameters of a connected device.
