​New features included in this release: 
  1. Added a downlink packet counter diagnostic tool to the SYSTEM CHECKS page.  To access it, go to: MAIN MENU > COMMANDS > SYSTEM CHECKS > PACKET COUNTERS.  The packet counters diagnostic tool shows how many downlink packets have been received and how many were missed (i.e. not received).  It also shows the signal strength of each packet as it is received as well as the average for the last ten packets received.
  2. Added a link to the SYSTEM CHECKS page that allows a user to view the receiver fault log. To access it, go to: MAIN MENU > COMMANDS > SYSTEM CHECKS > RECEIVER FAULT LOG. The receiver fault log contains code numbers that work very much like the trouble codes for an automobile.  Consult the factory if you are having trouble and some fault codes are logged.
  3. Updated firmware to support a new version "D" of the Mx220 Receiver.  Version "D" has a new GPS module that supports reception of both the USA GPS system and the Russian GLONASS system. The module was changed because the older GPS module used in the version "C" receivers is now obsolete and is no longer available. This firmware change is backwards compatible. It can be used in the older version "C" receivers as well as the new version "D" receivers.
