Connect to PC & Downloads

The newest software is designed to make survey work easier.

The device can be connected by means of standard USB A - USB B cable. Special software is available for download.

The software is compatible with Windows 32/64 bit and MAC OS. It provides possibility of automatic generation of IMO-like reports for all types of tested equipment.

A surveyor’s paper work can be now reduced to minimum: just generate a report, print it and sign! Or save it and send by e-mail. As the reports are saved in doc/pdf format, you can put your logo, contacts, etc.

* Mac OS and Windows 10 doesn’t require any drivers installation. For Windows 7 and 8 VCP STM driver should be installed for proper connection on first run.
