1. Install NTP from Meinberg

2. Edit ntp.conf

Open Notepad as Administrator, and then open c:\Program Files (x64)\NTP\ntp.conf

Add these lines:

# VK-162
#server 127.127.20.6 minpoll 3 maxpoll 4 mode 80 prefer
#fudge 127.127.20.6 refid NMEA time2 0.052 minjitter 0.1

# LEA-M8T
server 127.127.20.7 minpoll 3 maxpoll 4 mode 80 prefer
fudge 127.127.20.7 refid NMEA time2 0.08 minjitter 0.1

3. Restart ntpd

Open the Services control panel. Scroll down to Network Time Protocol Daemon. Right click on it and choose Restart.

4. ntpq

Open a Command Prompt windows and type ntpq -p in it. It should show the current NTP status. If the GPS was detected on the correct COM port, it should be listed as well:

C:\Users\matt>ntpq -p
