Collection, an option to obtain the Robotic screen (search and joystick features) is available. After all sets are collected, the user is prompted whether to move to a new setup station, collect still more sets, or review the set data. Close this dialog and Set Collection is complete for that backsight and foresight. Topcon APL1 This is an older Topcon robotic total station with excellent tracking. It’s a larger instrument often used in construction and machine control applications. It communicates only by radio with the 2ASx type radios. You must set the Com parameters on APL1, you only have to do this once. 1. Turn the APL1 on. 2. Press . 3. Press for Parameters. 4. Press for COM. 5. Press for Terminate. 6. Select ETX (ONLY) and press to accept. 7. Select F2 for Transfer Speed. 8. Select 9600 and press to accept. 9. Select F1 for Bit Format. 10. Set to BS, S1, and NONE, Press to accept. Putting the APL1 in the “Remote Mode” 1. Turn the APL1 on. 2. Press . 3. Press for Remote. 4. Press for Remote. The total station is now in the Remote Mode. Settings (Topcon GTS TS) Most standard Topcon total stations will work configured to Topcon GTS Series. This includes the Topcon 200,300,600,700,2000 and 3000 series instruments, and newer models such as the Topcon 230 (which uses Bluetooth wireless communication). This driver does support the reflectorless capability of the “thousand” series instruments (Topcon 2000 and 3000, for example). Typical baud rates for instruments in this group are 1200, E, 7, 1. Topcon 200 Series This is another option that can be tried when the GTS Series or other configuration does not communicate. It uses a different speed and mode of linkage. Topcon 300/600/700/2000 Similar to the Topcon GTS Series, these drivers offer the reflectorless option. Typical baud rates for instruments such as the Topcon 303 and Topcon 313, for example, are 1200, E, 7, 1. Topcon GTS 3/3B Series This driver supports the older Topcon GTS 3 and GTS 3B standard total stations. Some of the GTS Series Topcon instruments offer Reflectorless, and in stakeout routines and Sideshot/Traverse (both graphics and text modes), there is a convenient reflectorless icon at the top of the screen to turn on/off reflectorless and show current status. (See discussion of Leica TPS above.) Configure Base/Rover Configure Base For GPS equipment, it is necessary to set up the base antenna and record the correct antenna height, the antenna type (for certain equipment), and the methods used for localizing (obtaining the desired coordinates). This is accomplished with the command Configure Base, which only appears in the Equip menu if a GPS instrument is selected. Much of Configure Base is common to most instruments. For example, the Base Ant. Height would be entered in feet or meters, depending on the setting specified in Units within Job Settings. Vertical or Slant height refers to the method used to measure the height of the base antenna. Vertical refers to the distance from the ground point to the antenna disk, measured plumb. Slant refers to the distance from the edge of the antenna disk down to the ground point directly beneath the center of the antenna. Elevation Mask refers to the degrees above the horizon above which satellites will be used for GPS “correction” calculations, and below which satellites will be ignored. Keep in mind that it is not always better to lower the elevation mask below 10 or 15 degrees. Satellites closer to the horizon than 10 degrees will 42
