Computrac 200 speed input

[cyclone jim]

Can a JD Computrac 200 use a speed input other than radar?  I haven't been able to find a users manual.  I think it can show seed without speed input if you start it up correctly.  Population reading would be nice but not essential for an old bean planter.

yes. you can use gps signal to do it. phone ag express electronics out of des moines iowa. I have used it on a trimble 750 and jd gps.

or u can go manual speed.. but u need to plant CONSISTENLY at that speed and ur cal needs to be good to get a good read.

Not too worried about pop. Just want to know it's putting beans in the ground. How do you set it for manual speed?
