Attached at the bottom of this Article is a document by Ken Trent to help connect a GPS Rover to a Cellphone Modem or Base Network.


Bluetooth Phone Instructions:
---------------------------------
1.  Follow the instructions in our Knowledge Base at the link below for connecting to a Bluetooth Phone:

SurvCE Settings for a Bluetooth Phone


2.  Connect a cable from COM1 on your Data Collector to the GPS Rover Receiver

In SurvCE Version 2.56 and higher we support a "cable-free" solution with certain makes and models of GPS Rover receivers if your data collector and GPS Rover receiver support bluetooth:

1) Topcon GPS Rovers with Topcon Firmware 3.4 or higher = set the RTK Port in the RTK tab to "Data"
2) Sokkia GRX1 = set the RTK Port in the RTK tab to "Data"
3) Trimble R8 Model II or older = set the RTK Port in the RTK tab to "Data"
4) Ashtech ProMark 500 or ProFlex 500 use Cable-free automatically when Comms is on Bluetooth
5) Sokkia GSR2700ISX = you must have a Windows Mobile data collector and follow these steps below:

Sokkia GSR2700ISX on a Windows Mobile data collector

!!! PLEASE NOTE !!! in SurvCE Version 2.09 and older if you are using a Bluetooth Phone with SurvCE YOU MUST PLUG IN A CABLE or you will remain in an Autonomous position and you will not be able to use your GPS Equipment until you follow Step #2 and plug in a Cable

3.  After following Step #1 to get your data collector on the Internet open up SurvCE


4.  Tap the Equip tab / tap GPS Rover / Select the Make & Model of your GPS Rover


5.  Tap the Comms Tab / select Bluetooth / tap Configure and use "Find Receiver" if your GPS Rover is not listed under "Instrument"
 

6.  Tap the Receiver Tab if applicable:
    a. enter in your Rover Rod height
    b. set the Elevation Mask to 10
    c. make sure to set the "Position Rate" to 1hz or 2hz {Do not use 5hz or higher}


7.  Tap the RTK tab:
    a. Set the Device to "Data Collector Internet" / tap the Configure button to the right
    b. Set your "Data Collector RTK Port" to Com1 / tap the Green Checkbox


8. Select NTRIP as the Network {or select the proper network}:
    a. Tap the Configure button to the right of the Network Type
    b. Fill out your IP address, Port, Username and Password / tap the Green Check
    c. Select the desired Base ID you would like to use from the list / tap the Green Check


9. This will return you to the RTK tab: 
    a.  Set "RTK Port" to the proper Port Number or Letter labeled on the GPS Rover Receiver that we plugged the cable into in Step #2
    b.  The Baud Rate / Message type / Base ID and "Send Rover Position" should all be set correctly if using NTRIP {If you are not using NTRIP fill out the Message type and "Send Rover" checkbox}

10.  Tap the Green Checkmark in the Upper right corner to Finalize the "GPS Rover" routine and it will scroll through a series of messages then say "Successful Connection".  Now you can go into Equip / Monitor Skyplot and verify that you are in a FIXED Status {may take a minute or two} then tap the "REF" tab in the upper right to see the Base Data where you are getting corrections from.


***PLEASE NOTE:  After going "FIXED" one time using the steps below we recommend exiting out of SurvCE / Powering off the GPS / Powering off the Cellphone then following the steps below to verify your new settings:
   1) Power on the GPS
   2) Power on the Cellphone
   3) After the GPS and Cellphone have had 1 or 2 minutes to initialize - Open SurvCE
   4) Tap Continue Last Job / Tap Equip / GPS Rover / tap the RTK tab / tap "Configure" next to Data Collector Internet
   5) Select your ISP from the pull-down list and tap the CONNECT button
   6) When it says "Connected" tap the Green Check in the upper right
   7) Tap the Green Check in the upper right again to Initialize your Rover Connection
   8) Verify that you can go Fixed in Equip / Monitor Skyplot
   9) When your done using your GPS Equipment and want to shut down you SHOULD DISCONNECT your cellphone by going into Equip / GPS Rover / RTK / tap Configure next to "Data Collector Internet" / tap the "Disconnect" button to disconnect your cellphone
  10) tap Green Check / tap the X in the upper right to get to the Main Menu of SurvCE - it is now safe to power off the Data Collector and power off the GPS
