TROUBLESHOOTING
If problems occur with the use of the converter, check the following points:
PROBLEM CHECK
The “POWER” LED does not come on Check that the PC's USB socket provides for the supply
of the 5 V needed to power the instrument
The “Rx” led remains on continuously Check that the RS485 or RS232 cables have not been
swapped
The received data is incorrect Check the communication speed
The S117P1 product is a converter capable of realizing an asynchronous RS232 serial, an RS485 serial or a TTL,
using a USB port on the PC.
Thanks to the driver provided, the serial interface is treated by the operating system as a standard system serial
port, allowing the use of the product directly through any software capable of communicating with the standard
serial ports provided by the operating system (COM1, COM2, etc).
The RS232, RS485 and TTL ports are also electrically isolated from the USB port, allowing eliminating many prob-
lems of electrical noise that can occur for example when the connected equipment is very far from the PC.
The S117P1 has an internal power supply of 12 Vdc @ 100 mA available on the terminals which can be used to
power a Seneca module.

INSTALLATION REGULATIONS
5/8
As regards the S117P1 instrument, there are no particular precautions to follow, except that of using a shielded
cable for the RS232 and RS485 lines for long connections or connections in noisy environments.
CONNECTION TO THE Z-PC-DINAL
It is possible to directly connect the S117P1 to the Sene-
ca bus as shown in the side gure.

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. The standard serial port of the PC with which the device is identied is the following:
/dev/ttyUSB0.
As for Windows operating systems, it is important to stress that the procedure consists of two distinct phases
equally important for the nal use of the instrument. In the rst part the driver of the actual serial converter will be
installed. Through the second phase the virtual driver will be installed which will allow the use of the peripheral as
a standard serial port of the operating system.
If you are using Windows 7, these two phases are identical and are followed step by step, while for other versions
of Windows the second part is automatically managed by the operating system without further dialogue with the
user. Below is the installation procedure for Windows 7.
DRIVER INSTALLATION WITH WINDOWS 7:
Connect the instrument to the PC already switched on, so that the operating system can detect the presence of
the device automatically. As soon as the operating system detects the presence of the converter, the installation
will begin and the following messages will be displayed:
FIG. 1
FIG. 2

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, congure as in Fig 3.
On the next screen proceed as follows:
At the end of the search for the driver, a screen appears that shows the update and installation have been carried
out correctly. It will therefore be possible to see the instrument among the installed USB devices and among the
serial communication ports. (COM1, COM6 etc..)
