The easiest way to get Trimble machine control to run off a Topcon base is to run a HPB450 external radio off the Topcon base. You also need to replace the 900 radio on the machine with a 450. I've set up dozens of machines this way.
Welcome to HEF, and thanks for the tip. I have had the same question in the past, and now have the answer if it comes up again.
I will give you my opinion what I like for the gps I like topcon I have it on all 4 excavators and both my dozers so to be buying another dozer so it will also have it on it I like toocon that's my opinion
Were running a 140M trimble with the remote cell base that is 13 miles away alongside an 8 year old topcon system on our 140H. So far they have been within a couple hundredths of each other. We recently set up a repeater for the trimble machines because of a couple of blind spots. The Topcon system is running off of an onsite base. Our 8 year old fc100 data collector is still dead accurate also.
We are also running our 8R with the same old Topcon system and a 345D with the cell base Trimble. I think the Trimble is more operator friendly, but I think the Topcon is better tech.
It seems that Topcon 3dmc2 is usually a single Antenna system. Can you get this in a dual antenna set up? If it is a single antenna how can you run automatics on both sides of the blade?
because it has a slope sensor
So 3dmc2 does everything with a single antenna that trimble does with 2 antennas? Sounds like this 3dmc2 is hard to beat.
yes and it does it at twice the speed
The number of antennae on a 3D machine control system is a separate issue from the use of an inertial measurement unit.

sorry but thats not the case the two antenna setup is by far the most accurate system and faster in the way that when you change direction the system allways know excactly where your blade is where the one antenna system (doesnt matter if it is 3DMC2)will first have to calculate positions of your blade and the direction of machine

on top of that i can tell you that Trimble has just released their firmware version 12.2 with grade max for dozers that gives you more than twice calcultion speed of glonass signals in the antennas which gives you better speeds and grading capabilitys than 3dmc2 just by adding software instead of adding extra sencors and other gadgets.
this new software also gives yoy 5 adjustable settings that you can adjust while you are grading in automatic mode without any delay in speed
and with Trimbles connected site and connected machine everything works wireless with two way data and as built data synced back to office in the background
havent herad or seen any other brand that can do the same

What I have heard from both Trimble and Topcon as well as a few equipment manufacturers, it won't be too long until the antenna's are gone altogether. Seems the industry is actually heading towards full-automation and full-autonomy, meaning in 20 or 30 years their won't be Operators.
CAT, Volvo and Liebherr reps have told me they're working towards complete machine integration controlled by both US and Russian GPS with millimeter precision and the mast mounted antenna's will be a thing of the past. The antenna's will be atop the cab and barely visible. It appears that US and Russian military's are improving their systems to the point where the private sector will soon have access to what they consider "old" technology. This same old technology allows for GPS guidance of missles and bombs and affords pinpoint accuracy on delivery.
You'll no longer need grade stakes for anything, Dozers, Wheel Loaders, Excavators will all know where they are and what they need to do. Yes, I know they can do this now but not to the degree that's coming. There'll come a time just before full-autonomy when Operator's sit in a Command Center and remotely control all machines. That should be very interesting...

Just an add-on to my original post. The systems that are in development and coming soon to a jobsite near you will be 2, 3, and 4-axis systems which can determine a machines location and attitude with absolute precision and accuracy. The sensors being developed are wireless and either Radio Frequency Identification (RFid) or BlueTooth Technology (BTT) which will eliminate wiring altogether and they will be hardened or armoroed to deal with the rigors of heavy equipment applications. Since LCD screens are becoming more and more prevalent in machines there will come a time when all necessary information will be displayed in one location, and it is rumored that Heads Up Displays (HUD) will be coming too.

Have you used version 12.2? I'm eagerly waiting to try it, but the only CB460 (required for 12.2) we have is in a D6T that's down with engine problems right now. All the others are CB430's.

yes i have and it works incredible good you can set your valve speed while you are going in automatic so you can see imediate result and the valve speed has five different settings now over the older versions two

and there is good functionality in it for excavators too

you can set your valve speed while gradding in the 3dmc2 now, and 3dmc2 has 6 ways to change your valve speed, 2 for tilt and 4 for up and down. Topcon's system can fine grade to less then a tenth of speeds up to 11 mph! Trimble cannot, yet anyways
