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.
