Please note that a receiver can only be a base for at most two rovers, one using RTCM, the other using CMR.

You shold always use the most recent version of Survey Controller software.

If you have a 37779 Rev B and at 5700 then it is much easier to get everything going, there is a good chance it will work first time. See the basic configuration page
