I tried to output correction thru emlid.caster to 3rd party receiver but I found that my RS2 is sending out correction as RTCM3.3 and my receiver is accepting up to RTCM3.2. I cannot find if thats possible to choose which RTCM3.X version RS2 is sending?
You can use the legacy messages on Reach RS2. To enable them, connect to the unit via ReachView 3, go to the Base mode tab, and choose Show legacy messages option:
