#2 RS232 & #2 RS485/422 Over USB Isolated Multiport


IP Electronix A380N is an USB Adapter Multiport that provides #4 Serial COM Ports via its USB connection and is compatible with RS232 standard devices RXD, TXD, RTS, CTS, DTR, DSR, GND; Also, RS485 standard devices differential (Data+ & Data-); and RS422 standard devices differential (TX+, TX- & RX+, RX-) signals. A380N is fully Plug & Play and enables your laptop or workstation with the ability to communicate between a USB port and up to #2 RS232, #2 RS485/422 serial peripherals with baud-rate from 300bps to 230400bps simultaneously.

A380N supports Point-to-Point and Point-to-Multi Point Party Line network topologies. Since RS-485 is a Half-Duplex standard, switching between Transmit and Receive is doing automatically and no further signal (such as RTS) is required.

A380N supports a wide range power supply and is working with DC voltage between 8V to 48V. Protection against Surge, ESD and EMI is considered in its design and also has 3kV insulation between USB and RS232/RS485/422 sides. Furthermore, all the ports are insulated from each other too.

A380N is designed for industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems and DCS Systems …

A380N comes complete with drivers for Microsoft Windows. Drivers are also available for Linux, Mac OS and Android.
