The following information describes the various options available for the Sokkia Set total stations.

• 1-Way vs 2-Way: The 1-Way option mimics the operation of most total station instruments using SurvCE.  The 2-Way option has the one big advantage of sending the angle to turn into the instrument during stakeout, so that looking at the instrument panel, you “turn to zero” to aim at the target point. It is recommended that Nikon instruments be run in Sokkia Set emulation mode, enabling the 2-Way communication.

• EDM Mode: Available methods are rapid and fine.
• Target Offset: Enter the prism offset here.

• Zero Hz Angle to Target: This option specifies whether or not SurvCE will set the horizontal angle of the total station to zero in the direction towards the stakeout point. When stakeout is completed, the horizontal angle is set back to the original value. This option only applies to Sokkia total stations or to total stations such as Nikon which have a “Sokkia emulation” mode.

The driver applies to all current Sokkia total stations, including the 110M when used in manual mode.  It also applies to many non-Sokkia instruments which have a Sokkia or “Set” emulation mode, including Nikon, Pentax and Topcon.  The advantage of Sokkia emulation is that the Sokkia driver includes a “2-way” setting that will upload configuration settings into the instrument such as units, prism constant and the backsight circle.  Most important, for stakeout, the “2-way” setting will upload the angle to turn, so that you turn to zero to get on target.  The Sokkia Series 30R is reflectorless.

The “On” key is the upper right, which takes you to the “Measure” screen where it is ready to work with SurvCE.  Commands would not be accepted, for example, if you were in the “Config” screen.  Use the instrument to activate reflectorless mode, and in SurvCE, be sure to set target height to zero.  The gun will control prism offset in non-prism modes.

Sokkia Set 110M Series

This driver is necessary to utilize the motorized features of the 110M.  For example, in stakeout, it will turn to the point automatically.  The motorized features will turn to the appropriate horizontal and vertical angle in most commands when the 110M is set to “Remote” mode.

Note that baud rates on the 110M must be set to 9600 in remote mode but are typically set to 1200 baud in direct mode.  Change on the instrument and in SurvCE, Equip, Com Setup. The Settings options for the 110M are shown below:

Joystick speeds are 1 to 6 (for arrow key response turning gun).  For reference 6 is approximately 6 degrees per arrow press.  Search types are Sight (field of view of gun, or 1 degree, 30 minutes or 10 meters at 100 meters), H Wide, V Wide and HV Wide.  The wide views are 6 times field of view.  Auto Search before Read finds the prism center exactly before taking a measurement (useful in Set Collection, for example, and in Stakeout).  Run Remotely sets the left and right turning of the gun, referenced from the pole, and not from the instrument.  This is distinct from left and right referencing for stakeout which refers to movement of the rod.  For the Sokkia 110M with Remotocatcher, there are 2 buttons in the joystick screen for RC Search:  “RC Left” and “RC Right”.  Left and right will be determined by the Run Remotely setting.
