EDW-100 Serial to Ethernet Adaptor
The EDW-100 is an is an Industrial Ethernet to serial adapter or Ethernet Terminal Server, designed for industrial use in harsh environments. The unit use standard TCP/IP protocols together with serial equipment, it allows almost any serial devices to interface through a new or existing Ethernet network. Two EDW-100 units can be used to create a simple point to point link or multiple units can be linked to form a one to many application all using Ethernet as the medium to transport the data. A point to point application can be configured with both UDP and TCP, if TCP is used the unit can act both as a client or as a server.
