ELO E221ZKE001
to control or diagnose remote device. This GPIO maintain ±12V
levels. It can be configured to aware (e.g. by an e-mail) based on
states of those binary inputs.
2.0 How does it works?
The adapter converts RS232 signalling to the Ethernet interface. It
transfers all signals of the RS232 except RI. RS232 interface is
presented with DB9M (D-SUB, Canon), whereas Ethernet is lead
out via standard Ethernet RJ-45 socket.
Adapter can operate with full duplex with maximal bitrate
230kbps. The Ethernet layer can communicate with 10 and
100Mbps.
3.0 Installation
This chapter describes the adapter E221 installation process. The
process is divided to sub-process software and hardware
installation.
3.1 Ethernet connection
Adapter meets IEEE 802.3 specification and is to be plugged in to
the network with straight UTP cable. When configured as
Serial
Bridge
, the cross-over cable should be used instead.
For the first time, the adapter is configured to acquire IP address
from DHCP server, so in the network must be such a service to
dedicate IP address (e.g. AP – access point, router..). It can be later
changed to the fixed IP address.
3.2 RS-232 connection
A DB9M (D-SUB 9 pin Male) connector is wired as DTE, it means
that device with the same connector (DB9M), wired as DTE, must
