For any problems with the converter, verify the following points:
PROBLEM
The "POWER" Led does not light
The "Rx" Led is steady on
The received data are not correct
The CD containing the instrument's driver is provided to the user.
In this section the installation procedure of the driver will be briefly described.
It is necessary to specify that the installation in Linux (with Kernel 2.4.20 or later) environments is automatic
and does not need the CD with the driver. The standard serial port of the PC which identifies the device is
the following: /dev/ttyUSB0.
As regards Windows operating systems, it is important to underline that the procedure is divided into two
phases which are both fundamental for the final use of the instrument. On the first phase, the driver of the
out-and-out serial converter is installed. By the second phase instead the virtual driver will be installed: this
will allow to use the peripheral as a standard serial port of the operating system.
If case of use of Windows 2000, these two phases are identical and are performed step by step: the user
has only to follow the guided procedure; instead in Windows 1998 the second phase is automatically
managed by the operating system without any further dialogue with the user. In Windows XP the two phases
are performed very quickly by the operating system if it the CD with the drivers has been inserted.
For the correct installation it is important to insert the CD with the driver and connect the device to the PC
already turned on, so that the operating system may automatically detect the presence of the device.
At this point the the user has only to follow the guided installation.
VISUALIZATION OF THE VIRTUAL COM PORT
At the end of the installation, it is possibile to view the name which has been assigned to the virtual serial port
associated to the used S107USB or K107USB device.
For example on the following Device Manager panel, it has been identified as COM7:
MI001075-E
Verify that the USB port of the PC provides the 5 V
which are necessary to supply the module.
Verify that the RS485 cables have not been swapped.
Verify the communication speed.
