Introduction

This new range of serial to USB solution (USBPort/x) offers performance, simplicity of installation, security, robustness and high reliability at affordable prices.

 

USBPort/x is proposed in two models : 2 and 4 isolated port with 3 in 1 serial interface RS232, RS422 & RS485 in order to cover all technical requirements of industrial environments.

 

USBPort/x installation is quite simple as the product is instantly plug & play, it doesn't require any IRQ, DMA or I/O port resources.

Installed serial ports are considered by Windows 2000, 2003, XP, VISTA, SEVEN & Linux operating systems as computer's standard COM ports.

 

USBPort supports up to 3 Mbps over the serial link. A decimal divider makes it possible the program non-standard highly accurate baud-rates.

 

Technical characteristics

 

 

Interfaces

 

2 or 4 RS232 / RS422 / RS485 asynchronous serial ports for USB 2.0

 

 
 

 

RS signals

 

RS232 mode : TxD, RxD, RTS, CTS, DCD, DTR, RI & GND
