There is another option: Download ProLink v1.5 off the Sokkia website. Prolink can read in a text coordinate file exported from Civil3d, create the SDR equivalent and upload it to the instrument. It also downloads, reduces to coordinates and produces a text file which can be imported to Civil3D. We tend to keep control files in SDR format on the computer ready for upload when needed.
Carlson Connect expects a com port link (I have not looked at the 2007 version yet). We have problems with new notebooks that don’t have com ports, we have found the Aten USB-Serial converters don’t always work properly with Carlson Connect. It would be great if Carlson Connect could produce the SDR file on the PC and we could rather transfer it using the Prolink, Flash cards or Active Sync, depending on the gear that’s going into the field. Carlson Connect 2006 also dos not give you the option of choosing a Civil3D Point Group to upload, which the exporting of a text file from Civil3D does.
