All older guns are generally numbered set; like the Set3. On these units, the baud and parity are hard coded and cannot be changed. Most of the newer guns will use the "SetsB" as their model. If the data starts coming out in the wrong position, Slope Dist where Zenith should be, the checksum is in the wrong position. toggle the checksun to yes on the gun. The new XL has 4 decimal places for distance, this must be toggled back to three or it will result in a failed shot. The TDS cable will be marked with either SOK, TPC, or LTZ. A Topcon cable will work with the Sokkia/Leitz gun. Pentax and Nikon cables will connect, but do not use the same pin configuration so they will not work. The Sokkia Power Set series (1000, 2000, 3000, 4000) have SDR OnBoard but will work with the SETs driver when the Gun in Measure mode. For the 100 series (1100, 2100, 3100, 4100) use the SETsB driver.
