Leica/Wild Total Station to Data Collector Cable connects Leica instruments to data collectors from Spectra, Trimble, Sokkia, Topcon, Carlson and most other data collectors via standard 9-pin (RS232) serial port connecton.
The standard coil cable is approximately 6-foot long and its design provides the durability one might need for any construction or survey environment. In fact, the cable has been tested to withstand a pull strength of over 100 pounds!
This cable is sometimes called the computer download cable, since it can be connected to 6-pin LEMO to 9-pin serial ports. If your handheld field computer or PC doesn't have a 9-pin serial port, you will need a serial to USB adapter, which is sold separately.
