DNP-3 Ethernet Gateway. Interfaces include one
10/100BaseT ethernet interface and two RS-232/422/485
serial9-pin interfaces. A version is also available with two
opto-isolated RS-422/485 interfaces.

The gateway allows serial DNP-3 RTUs to communicate and
interoperate with DNP/IP (either TCP or UDP) based
controllers. The DNP-3 standard protocol is an asynchronous
protocol designed to connect directly to computer asynchronous
ports. DNP-3 has been extended to operate over Ethernet using
the IP protocol suite. This gateway converts between the DNP-
3 IP protocol and DNP-3 Serial protocols transparently.
Normal operation would consist of one or more Ethernet based
computers functioning as DNP-3 Host and one or more DNP-3
slave devices (usually RTUs) connected serially to the gateway.
By using RS-485, multiple DNP-3 slave devices may be
connected to each of the two serial ports on the EDNP-3. If
using RS-232, one DNP-3 slave device may be connected to
each serial port.
The EDNP-3 is designed for mounting on a standard DIN rail,
or for direct mounting on a wall. For easy connection to your
LAN, the gateway supports 10BaseT or 100BaseT , half or full
duplex with auto-sensing or pre-configuration.
