PC Interface

7. PC interface
The LT51 opto-isolated USB interface can be connected with a standard USB
cable, to a PC running a Windows 98, 2000, XP, Vista or 7 OS. This interface
allows a user to upload stored results, control the instrument and update the
LT51 firmware.

USB drivers

Before using the LT51 PC interface, the appropriate USB drivers must be
installed on the PC. These drivers are automatically installed when installing the
freely available LT51View Application on a PC with a Windows 98, 2000, XP,
Vista or 7 OS.
The USB drivers may also be installed manually by downloading the required
files (according to your OS) from the FDTI website: http://www.ftdi.com, or using
the Windows Update feature during the "Found New Hardware Wizard" for
Windows OSs.
One driver is required to support the USB interface, while a second Virtual COM
Port (VCP) driver, enables the USB device to appear as an additional COM port
available to the PC. Application Software can then access the USB device in the
same way as it accesses a standard COM port. The next available COM port will
be assigned permanently to a unique LT51.
