Test and Measurement Forum

I want to connect my ADC 16 to my laptop. As I only have a USB port on my laptop, i used a COM to USB adaptor to connect the logger. However, when I start the software, i get a message saying that the device cannot be found. can you give me advice on this please?

Hello

Thank you for your post.

I recommend checking the voltages of the serial port to see if it is supplying the correct voltage to the unit on the correct pins. It should be as follows:

Pin 4 > -7V
Pin 5 Gnd
Pin 7 > +7V

If it is not supplying these voltages then we can either supply you with a
diagram showing how to power the device externally.

If the port is supplying these voltages then I recommend that you check the COM port number assigned to the adapter, you will find this in the device manager.

Best Regards
