1.0 Introduction
Ethernet as a communication medium becomes widely used not only in
commercial domain, but becomes more popular in industry automation
too. A RS485/422 interfaces are intended to connect multiple devices for
distances up to 1600m; RS485 allows half-duplex communication, while
RS422 full-duplex. An adapter E222 allows to integrate the RS485 or
RS422 devices into the Ethernet network thereby bridge long distances.
Bellow described adapter allows to connect RS485/RS422 devices
together over the Ethernet network; it also allows to connect more devices
to a single network gateway (i.e. computer).
1.1 Application
This communication device altogether with supplied software allows
setting up following profiles:
1)
Real Port profile. Adapter allows to connect a device with
RS485/422 interface straight to computer via Ethernet protocol
with virtual port application installed on,
2)
Serial Bridge profile. Adapter connects two devices with
RS485/422 interfaces like they were connected by cable; it is
technique so called “serial tunneling”
3)
TCP socket profile. Configured as TCP client or TCP server,
establishes connection among these devices
4)
UDP socket profile. Configured as UDP client or UDP server,
establishes connection among these devices.
5)
Custom profile. Experienced user can access all settings both
network and serial interfaces.
2.0 How does it works?
The adapter converts RS485/422 signaling to the Ethernet interface. In
half-duplex mode selected, it can drive the transmitting direction
automatically. RS485/422 interface is presented with DB9M (D-SUB,
Canon, male), whereas Ethernet is lead out via standard Ethernet RJ-45
socket.
