I'm running a Trimble 5800 rover, Trimble 5700 Zephyr base, and a PacCrest PDL, and a TSC 1. I import a coordinate system from another job for the State plane, change the projection to what I assume is correct from another survey we did in the area (I haven't done the math provided from the state to find the projection, but the last job we did in the area is supposed to be on the county coordinate system). I started the base, told the TSC "here" on WGS84 lat long coords, then over rode them with the published data provided for the Geodetic horizontal control monument, and then finished starting the base. But the base did not transmit.
I tried starting the base using a known coordinate system/projection from another county and it worked fine, but every time I tried to use the problem county projection the base would not transmit. Should I just use the lat long the base wants to use and not override with the published coordinates, and just calibrate with the projection I need?
Are you using the same survey style?
This is just a guess: if you are trying to start up a file in NAD27 then you need to have imported the combined grid file to allow the collector to work. The combined grid file is a file that does a "guesstimation" of a NAD27 coordinate from GPS numbers. Also, if you are trying to apply a geoid file and you have a geoid subgrid that doesn't cover the area you are physically surveying in, then the job won't start up. And, if you have a name incorrect between geoid files you will have problems. For instance, if the file you are trying to use has a geoid file named geoid09 and the controller has been downloaded with a geoid file named Geoid09 then you’ll have issues.
It sounds like you're trying to open a NAD27 projection; then I'd guess you need the combined grid file.
on your collector, Pick configuration, then survey styles, then pick your current survey style, then pick base radio. Make sure the radio type and port on your 5700 reciever is correct. look on the reciever where the cord plugs in at and there is a port number printed on the reciever there. If it still isnt blinking TX then check the baud rate and parity on both the survey style on the collector and radio to make sure they are both the same. after that you should be good to go.

I must be missing something here. The key term in this entire problem seems to be "calibrate". If you're calibrating to a local datum, then just toss all that other mumbo jumbo out the window. 10,000/10,000/1,000 works just as well.
But if you're on SPC, or at least think you are, then I think I'd back up and go with OPUS or something.
Good luck
Thank you gentlemen for your help. Until I can get a good train up on geoid models and projections, I think I will just calibrate the site, using our current model. And hope the coordinates are close enough. We have plenty of monuments with published coordinates that we can check into and ensure we are not too far off.
Apparently the majick box is two much four me too figoor out.;-)
Don't plug the radio cable into the base UNTIL the base is started otherwise the radio will try and pull juice from the handle battery and not the deep cycle.
As far as your method of the job, that's a whole other thing. Nothing sounded right.
Since you're running trimble, use TGO. Set up a job, set your projection, import your points, then d/l into the collector. No muss, no fuss, no overriding, nada. Much easier using the KISS principle with this stuff.
BTW, the radio thing is dead on. It's the same way on our 5700 as it is on our R8. Don't know why, but otherwise, it ain't working.
Again thank you gentlemen for the help. I appears the problem was not the way i was setting up the job. It was something a bit simpler than that. The manner I was setting up the job works just fine, I worked it out today. The problem was the power cord. There is apparently not a "fail safe" for unlearned people in the field computer, just a failure of power and recognition of the fact.
