Topcon GTS-235W to TSC3 Serial Connection

I am having a heck of a time getting this gun to zero from my TSC3.  The gun seems to connect as soon as I run "Station Setup" from the collector, but when I tell it to backsight it beeps but does not zero and the collector says instrument error.The baud rate is set to 1200, parity is even, stop bits 2.  I tried going up to 4800 on the baud, but I'm really grabbing at straws.  If anyone has any know how it is greatly appreciated.Thanks,Dan

FC-5000 Pocket 3D Won't display Full Screen

I was working the field the other day and somehow I managed to glitch out my Pocket 3D to where it will not boot in Full Screen mode.  I have tried using Tablet mode and that doesn't help.  I think its a Windows 10 thing.  Pocket 3D has limited menus for display so I have gone through all the menus and found nothing.I reinstalled the latest version and that didn't work. Any help is appreciated.

  • GPT3005 sorry

  • I am using a GRT3005 regarding below desperate plea.

  • Hi all,

    I have a serious problem. Shooting forsights and baksights for my fellow theodlight user on gridlines, I set a nail on that same gridline. When I attempted to interline on that nail, I discovered my foresight and backsite were way off. I was resecting all over the site shooting gridlines using verified verified 5 different backsite. All residuals were within 3 mm. How is this possible? Previously my points, prism and prismless were within two mm of two different top end Leica's, two different professional surveyors. It's a new top me total station running an old version of SurveyPro. Please please help me solve this.

  • Hi Charles,

    Please see diagram below.  you measure to the bottom of the unit but you need to make sure that you have it as SLANT on the logger if you are using Topsurv.  Hope this helps.
