Overview
The Trimble® CFX/Case IH FM-750 is typically configured to accept CMR format RTK
corrections from an Intuicom RTK Bridge
®
-X which in turn has been configured to connect to a
GPS/GNSS reference network. The intended audience for this document is a dealer or
integrator familiar with the CFX 750 and generally familiar with the Intuicom RTK Bridge-X.
The Intuicom RTK Bridge-X User Guide covers the steps necessary for its configuration.

2 Installation Instructions
Below is a diagram for the recommended installation of the Intuicom RTK Bridge-X utilizing the
equipment noted above.
Diagram 1
2.1 Configuration
• Configure the Intuicom RTK Bridge-X to connect to GPS/GNSS Reference network
and obtain CMR/CMR+ correction data stream from an appropriate single reference
station, such as a VRS.
• Configure the resulting RTK correction data to be output from the data port at a
known baud rate (a baud rate of 38400 is recommended).
• Confirm GPS and cellular antenna (typically a combined antenna with two coaxial
cables with TNC connectors) are connected and placed where they have good sky
view and good cellular signal.
• Configure the pinout on the Deutsch connector on the RTK Bridge–X to FMX
data/power cable to match the appropriate pin-out. See Pin-out Diagram 1
