USB to RS-485 Interface Converter With RJ-45 Port

Description

The AN-USB-RS485-RJ45 module is a cost-effective way to convert RS485 industrial buses to a USB interface. When connected to a PC USB port the AN-USB-RS485-RJ45 module is automatically detected and is installed as a native COM port which is compatible with any existing serial communication application. Multiple modules can be installed when using USB hubs thus allowing a hassle free configuration of a multi serial system without any IRQ or DMA configuration. They have 600W protect between the USB port and RS485 protects the PC from spikes or possible misconnections in the communication bus.

Features

The AN-USB-RS485-RJ45 converter can be configured for RS485  two-wire (Half Duplex) networks. When operating in two-wire RS485 the data transfer control is automatically done by the converter. Two independent and RS485 networks can be supported by one AN-USB-RS485-RJ45 module thus duplicating possible number of remote devices.
