Changing virtual COM port to use field probe with EMC32

Question

We are using EMC32 software for EMS measurements. Currently we have difficulties integrating a field probe. We cannot change the COM port of the field probe's USB/serial adapter and therefore cannot use the field probe with EMC32.

Answer

The virtual COM port can be changed within Microsoft Windows. Please refer to the Windows Device Manager. If you connect the device to the PC, it is automatically assigned to a virtual COM port with a port number. This port number is also available in EMC32.

Example:

COM ports in the Device Manager ...

3.) Now COM10 is also available in EMC32.

It is important to know that COM ports 1 to 10 can be used with EMC32.

To use your field probe with EMC32, you need to find a free port in this range.
