Connecting and Communicating via a USB Cable 

It is recommended to use a Type AB USB cable between a personal computer and a 
MD-P1 or MD-P1D Power Meter to set up the meter. The USB cable will also power 
the meter when connected to a computer. When using a USB cable with a computer, 
each USB port on the computer generates a unique comm port in the ViewPoint 
software, such as Com3 or Com4 (see Figure 4.) 

Commercially Available Examples: CablesToGo UPC 757120281023, Grainger 
5XFV4, Best Buy SKU 9457928 

 

 

A USB driver is installed when you install the ViewPoint software. 

ViewPoint communicates with the MD-P1 or MD-P1D Power Meter through a USB 
connection, using Modbus protocol in the service software communication with the 
meter. The USB connector on the meter can be used to power the unit during 
configuration. 

Initial Meter Setup 

Start ViewPoint software on your computer. Connect one end of the USB AB cable to 
your computer’s USB port and one end to the MD-P1 or MD-P1D Power Meter’s USB 
port on the side of the device (see Figure 4). 

Once communication is established between the computer and the power meter, you 
can configure the meter for the field. The 

Communications

 screen (upper left tab) 

should display first.
