Exsys EX-1331-4KVIS Manuale utente

Thank you for purchasing this RS232/422/485 3-in-1 Serial to USB

Adapter. It is an intelligent expansion module that connects to a PC or

server via the Universal Serial Bus (USB), providing high-speed serial

connectivity. The serial ports are fully compatible with RS232/422/485

standard by the bundled virtual COM port drivers. It provides a universal

mounting Kit which can be mounted on wall, DIN Rail and other

surfaces. Moreover, with the 4KV isolation, 15KV ESD surge protection

and USB Screw Lock Mechanism features, it is an ideal solution for

most critical applications.

There is an 8-pin DIP switch on the back side of the box for the required

settings. Their functions are described as follows:

Mode Settings:

The DIP switch has 8 pins, the first 3 pins (M0, M1, M2) are for mode

settings (RS232, RS485-2wire, RS485-4wire or RS422 modes), pin 4

(TERM) is to enable or disable terminator. Pin 5 and 6 (T+, T-) are to enable

or disable the bias for TX+ and TX- signals. Pin 7 and 8 (R+, R-) are to

enable or disable the bias for RX+ and RX- signals.

Note: Pin 5 to 8 are designed for RS422 and RS485 only and

should be set to OFF when you are setting the port to RS232 mode.
