Message Interface 

 
The H220 uses a NMEA 0183 interface, allowing you to easily make configuration changes by 
sending text-type commands to the receiver. 
 
The H220 also supports a selection of binary messages. There is a wider array of information 
available through the binary messages, plus binary messages are inherently more efficient with 
data. If the application has a requirement for raw measurement data, this information is available 
only in a binary format. 
 
For more information on NMEA 0183 commands and messages as well as binary messages refer 
to the 

Hemisphere GNSS Technical Reference

 Guide.  

 

Using PocketMax4 to Communicate with the H220 

 
Hemisphere’s PocketMax4 is a free utility program that runs on your Windows PC or Windows 
mobile device. 
 
Simply connect your Windows device to the H220 via the COM port and open PocketMax4. 
 
The screens within PocketMax4 allow you to easily interface with the H220 to: 

  Select the internal SBAS, external beacon, or RTCM correction source 

and monitor reception (beacon optional) 

  Configure GNSS message output and port  settings 

  Record various types of data 

  Monitor the H220 status and function 

 

PocketMax4 is available for download from the 

Hemisphere GNSS website.
