Do what Boomer24 says, though I would suggest using the AGRTCM34 mountpoint instead. Here is how to get to the page you need to enter the info.

Connect your display to the BR1 by going to the satellite icon, Data Transfer, then Network at the bottom of the page. The WiFi password is the AP password on the bottom of your BR1. Once you have internet on the 1200, do the following.

From the Home Screen:

1. Red Setup wrench icon.
2. Steering wheel/GPS tab on bottom of page.
3. Ag Leader NTRIP Setup about half way down.
4. Green Plus symbol, and give your profile any name you like.
5. Put in the url and port info Boomer24 posted.
6. Use AGRTCM34 mountpoint.
7. Enter your user name and password.
