Thanks mb2347, I will try the method listed in your agtalk link
"First make sure that you have the radar adapter cable plugged into port A on the back of the 750. To enable the radar output on the 750 from the home screen hit settings then system then advanced. In the advanced menu hit digital output. In the next screen it should say digital output mode and then disabled. Hit that button then select radar. Once radar is selected under the Digital output mode is now a frequency. Set that to 60hz and the speed cal on your raven should be set to 600. You may need to adjust the raven speed cal up or down a little bit to make the speeds match correctly."
Have you personally done this also? Did it work for you, and does it work with all 750's or do things need to be unlocked etc.
This procedure is correct. I usually set the output on the 750 to 57 Hz and then use a Raven speed cal of SP2 and 612 or so. There is no single "right" pair of numbers. The speed shown and used by the Raven is a combination of the two numbers used. The Hz number tells the 750 who fast to kick out the pulse and the Raven speed cal tells it what to do with it. This means that there are many "pairs" of numbers that would work well.
If the speed shown on the Raven is close but a bit slower than shown on the Trimble then increase the value of the Raven Speed Cal slightly.
