Installing the USB Driver

3.  Click on the + at the left of “Ports (COM & LPT)”. 

The indication “RION USB to RS232C Converter Virtual COM Port” should 

be shown as COM port name. If this is not shown, check the connection 

between the NL-42/NL-52 and the computer (step 1). If there is an “×” over 

the icon, the port is not functioning normally. Install the driver again.
