ELO E221ZKE001
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 RS232 interface is intended to connect two
devices with maximal cable length 15 meters. An adapter E221
allows to integrate the RS232 devices into the Ethernet network
thereby bridge long distances.
Bellow described adapter allows to connect two RS-232 devices
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
RS232 interface straight to computer via Ethernet protocol
with virtual port application installed on,
2)
Serial Bridge
profile. Adapter connects two devices with
RS232 interfaces like they were connected by cable; it is
technique so called “serial tunnelling”
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.
Furthermore, there is possibility to create GPIO port (general
purpose input/output) with five output and/or input binary channels
