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, MAC OS X and Linux. It provides possibility of automatic generation of IMO-like reports for all types of tested equipment. Even more, now a surveyor can generate one combined report of all the safety equipment tested on a vessel.
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. Add your company header with the logo and contacts in the user's profile, thus the test reports will be automatically generated with the header selected.
Linux, OS X and Windows 10 don’t require any drivers installation. For Windows 7 and earlier versions STM driver should be installed for proper connection on first run.
Latest update:
Windows 32 bits is supported! Before running the software please install FTDI drivers (available by link in DOWNLOAD section).
