SENECA S117P1 Asynchronous Serial Converter RS232
PRODUCT DESCRIPTION
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 problems 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.
MODULE LAYOUT
- DIMENSIONS LxHxD: 90 x 50 x 25 mm
- WEIGHT: 55 g
SIGNALS VIA LED ON FRONT PANEL
| LED | STATUS | LED meaning |
|---|---|---|
| PWR Green | ON | The device is powered correctly |
| RX Red | ON flashing | It lights up every time the instrument receives data |
through the RS485 / RS232 port
TX Red| ON flashing| It lights up every time the instrument transmits data
through the RS485 / RS232 port
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
