S107USB INSTALLATION REGULATIONS With regard to the S107USB instrument, there are no particular precautions to follow, except that of using a shielded cable for the RS485 lines for long connections or connections in noisy environments (please refer to the Electrical Connections section).
ELECTRICAL CONNECTIONS S107USB: the electrical connections of the S107USB are shown below: By inserting an external jumper between terminals T1 and T2, the terminator of the RS485 line is enabled. We also recommend to use a shielded cable for the RS485 line, in particular if long connections are to be made or in noisy environments.
DRIVER INSTALLATION The user is provided with a CD containing the instrument driver. In this section we will describe in detail the driver installation procedure. It should be noted that the installation in Linux environments (with Kernel 3.0.0-19 or later) is automatic and does not require the driver CD.

If the installation does not start automatically, you will have to proceed manually, following the instructions given. First of all you need to have an internet connection allowing the instrument to perform the driver update following the automatic procedure or by connecting (http://www.ftdichip.com/Drivers/VCP.htm). For the automatic proce- dure, configure as in Fig 3.
