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 cables have not been swapped.
The received data is incorrect
Check the communication speed
The S107USB and K107USB products, constitute an interface able to realize an asynchronous RS485 serial,
using a USB port present 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 RS485 port is also electrically isolated from the USB port, allowing eliminating many problems of electrical
noise that can occur for example when the connected equipment is very far from the PC.
