IP Relay HWg-ER02b connects a full RS-232/485 serial port and a set of two digital inputs and two digital outputs to the Ethernet. IP Relay HWg-ER02b features a truly full RS-232 serial port (9-pin). The serial port of the unit can be connected to a PC over the LAN, with the serial port accessible in Windows as a Virtual Serial Port (VSP). Its digital inputs and outputs can be controlled over the Web or through Modbus/TCP.
A built in web server is used for configuring. Using the free HW VSP3 application up to 100 remote serial ports can be connected to one PC.
Two devices can be connected in Box-2-Box mode. In this mode, the digital I/O as well as the RS232/485 serial line is extended (tunneled) over the LAN.
