Step‑by‑step

1

1) Connect via RxControl

Attach the antenna, connect USB, open RxControl, and connect to the receiver (virtual USB COM). Confirm a position.

2

2) Open DataLink and create two connections

  • Connection 1 (receiver): Click Serial → choose the USB COM → Connect

  • Connection 2 (network): Click NTRIP (Client) → enter IP/Port/credentials/mountpoint (next step) → Connect

  • Bridge the links: enable Link2 in Connection 1 and Link1 in Connection 2 so data flows both ways.

3

Enter RTKdata.com connection settings (Regional hostnames + IP fallback)

Use the regional RTKdata.com hostname where possible. If your device only accepts numbers or your network DNS blocks hostnames, use the numeric IP fallback. Keep ALL CAPS where noted.

  • Host (domain): rtk.rtkdata.com

  • Host (IP fallback): 13.56.117.10

  • Port: 2101

  • Username / Password: your RTKdata.com credentials

  • Mountpoint (ALL CAPS): AUTO (recommended) — or AUTO_WGS84, AUTO_ITRF2020, AUTO_ITRF2014

Only these four mountpoints are valid. Typing local CRS names as mountpoints will result in no corrections. Always use ALL CAPS.

4

4) Output GGA @ 1 s

In RxControl: Communication → Output Settings → NMEA Output

  • Stream 1 → select USB1 (the port DataLink listens on)

  • Tick GGA and set Interval = 1 s → OK

DataLink now sees GGA on Connection 1 and forwards it to the caster; RTCM flows back on Connection 2.

5

5) Verify FIX

In DataLink, confirm bytes in/out; in RxControl watch Autonomous → RTK Float → RTK FIX. If stuck on Float, ensure open sky and mountpoint = AUTO.

Notes

  • Some PCs expose two virtual COM ports over USB; you can dedicate one to RxControl and one to DataLink.

  • Heights are ellipsoidal; convert to orthometric with a geoid in processing if required.
