Preferred Connection via USB A to B Cable 

d.  Launch the ViewPoint HD application and press the CONNECT OVER USB button on the pop-up 

window. 

The meter should now be communicating. The ViewPoint HD application offers visual guides and context 
help to facilitate meter configuration. Read the ViewPoint HD overview section (below) or watch the 
tutorial videos for additional information on configuring the meter. By default, MD-xxHD meters are 
configured for DNS Ethernet addressing. A very common configuration sequence is using USB to 
configure a meter for Ethernet communications at a static IP address and then switching from USB over 
to Ethernet to locate it. This is facilitated in ViewPoint HD by pressing the 

Refresh Connectivity

 icon 

located in the upper right hand corner.
