The EDW-100 is an Industrial Ethernet to serial adapter or Ethernet Terminal Server. The serial interface is selectable between RS-232 and RS-422/485. The Ethernet interface is 10/100BASE-T and supports the following networking protocols: TCP, UDP, ICMP, IGMP, HTTP, ARP. Two EDW-100 can be used to provide a serial point to point link over an Ethernet network using either UDP or TCP. When using TCP the EDW-100 can be configured as client or server. In addition to a transparent serial point-to-point link and ethernet to serial adapter, the EDW-100 MG can also be configured to act as a Modbus gateway.
… Packing algorithm that enables the user to decide how and when the serial data should be encapsulated in a TCP or UDP data frame and sent out on the network. … Galvanic isolation, this feature eliminate communication errors. One of the most common errors is caused by potential differences between interconnected equipment. … Redundant power supply with wide input range. Theses feature along with the high EMC immunity enables the device to be used in projects where a high degree of reliability is required.
