SPECIFICATIONS
The ECM-RS2D module is designed to control any devices with
RS232/RS485 interface as well as be DMX512 controller.
The module is a bidirectional gateway between physical interface
RS232/RS485 and Ethernet network and supports multiple TCP/
IP connections for each serial port.
The device has 2 independent isolated serial ports.
The control, data exchange and configuration are all handled via
TCP/IP protocol.
The ECM-RS2D version is designed to be installed on a standard
35 mm DIN-rail.
