Introduction
The ADAM-4577/ADAM-4579 are an universal serial device gateway to
bring RS-232/422/485 to Ethernet. It allows nearly any device with
serial ports to connect to the Ethernet and share networks quickly. The
ADAM-4577/ADAM-4579 provides a quick, simple and cost-effective
way to bring the advantages of remote management and data accessibility
to thousands of devices that cannot connect to the network.
With the ADAM-4577/ADAM-4579, your existing serial devices can be
used in the most popular operating systems. There is no need to write
special drivers for specific operating system. Moreover, the ADAM-
4577/ADAM-4579 allows the serial device to communicate with other
devices peer-to-peer, without any intermediate host PCs. That saves a
lot of cost and effort. In addition, you can actively request data or issue
commands from the RS-232/422/485 side or Ethernet side. The data
can be sent bilaterally. Thus, the ADAM-4577/ADAM-4579 is especially
suitable for remote monitoring environments such as security systems,
factory automaton, SCADA, transportation and more.
The ADAM-4577/ADAM-4579 also features powerful functions such
as: high-speed data transfer, advanced security protection, auto-
detection of all network-linked EDG series products, remote firmware
download and more. The transmission speed of the ADAM-4577/ADAM-
4579 is up to 230 Kbps, outperforming the competition to meet the
demands for high-speed exchange. The ADAM-4577/ADAM-4579 also
provides a security option that protects all configuration settings from
being changed inadvertently, and blocks access to a specified ADAM-
4577/ADAM-4579. The above functions are offered to enhance network
security and reduce system malfunction due to unauthorized changes
made to the system. Another benefit is the ADAM-4577/ADAM-4579
allows users to remotely download programs to a designated device via
the Ethernet. This reduces the need for on-site maintenance and
diagnostics.
For fulfilling the different applications that connect to networks, the
ADAM-4577 provides 4 types of network architectures: Polling, Event-
handling, peer-to-peer, multi-host access (UDP protocol); and the
ADAM-4579 provides 4 types of network architectures: Polling, Event-
handling, peer-to-peer, and Controlling.
Compliant with any operating system
In the polling mode, the specific host PC can request the serial devices,
which are connected to the ADAM-4577/ADAM-4579, to send data via
Ethernet. All the data will be gathered in host PCs. In addition, the
ADAM-4577/ADAM-4579 supports standard networking application-
programming interfaces (API) such as WinSock and Socket, making
the ADAM-4577/ADAM-4579 a popular item in most operating systems
such as Windows, Linux etc.
Actively event /alarm handle
In the event-handling mode, if an event or alarm occurs from serial
devices, it will be immediately sent to the designated device via Ethernet.
Thus, it can reduce the load of the host PC and increase the performance
of the Ethernet.
Peer-to-peer transmission of data without intermediate PC
In peer-to-peer mode, data can be sent/received between two networking
devices directly without intermediate PCs. Users can add two ADAM-
4577/ADAM-4579's on both serial sides and transmit data from one
serial device to another via Ethernet. Serial devices don’t need to be
bundled with PCs. To increase the performance of whole systems, the
data can be sent to the devices that urgently need it.
Dynamically build up the connection from device to device
(ADAM-4579 only)
In controlling mode, the ADAM-4579 acts as a modem to the attached
serial device. It provides several modem AT-style commands in order
for serial devices to connect to different networking devices dynamically.
This saves a lot of programming effort and increases the performance
for data exchange.
Multi-host access (UDP protocol)
ADAM-4577 supports UDP protocol, it allows most 8 host PC accessing
data simultan eously. Via polling networking architecture. You can use it
according to your application.
