Overview
1.1 Introduction
The ADAM-4577 is a peer-to-peer data gateway
between RS-232/422/485 and Ethernet interfaces. This unit immediately
upgrades your existing device for integration into the Internet world.
The ADAM-4577 makes your serial devices behave just like networking devices. You can issue commands or transmit data from one serial
device, which connected to ADAM-4577, to any devices that are
connected to the Internet. This provides greater flexibility. There is no
need to constrain the serial devices to be bundled with a host PC
running on a different O.S. Besides, if you want your PLC or intelligent
devices which is running specific application program to connect to
any networking device dynamically, we provide several commands to
let the device to control ADAM-4577. The ADAM-4577 provides three
types of networking architecture: polling, event-handling, peer-to-peer.
In addition, ADAM-4577 supports UDP protocol .It allows most 8
host Pc accessing data simultaneously via polling networking
architecture. You can use it according to your application.
The ADAM-4577 features a lot of powerful functions such as: high
speed data transfer, advanced security protection, auto-detection of all
EDG series products, remote firmware download and more.Functionally
transparent and efficient, the ADAM-4577 is specially designed for
remotely controlling and monitoring devices via the Internet.
If you want to access the ADAM-4577, you must ascertain your
application software supports Standard networking application
programming interface (API) such as: WinSock Socket. The transmission speed of the ADAM-4577 is up to 230 Kbps, outperforming the
competition to meet the demand for high-speed exchange. The
ADAM-4577 also provides a high-performance RISC CPU and Real
Time Operating System to reduce CPU load. This element makes the
ADAM-4577 more stable and reliable during data transmission.
Another benefit is the ADAM-4577 allows users to remotely download
programs to a designated device via Ethernet. This reduces the need
for on-site maintenance and diagnosis.
The ADAM-4577 comes with a Windows-based configuration and
testing utility. The configuration utility can auto-detect all ADAM4570/4571/4572/4579/EDG-4504s on the local network. It also lets you

Getting Started
This chapter includes an overview of the ADAM-4577 hardware
installation procedures. As mentioned in the previous chapter, the
ADAM-4577 comes ready for all network connections, including
Ethernet, and RS-232/422/485 port connections.
2.1 Understanding ADAM-4577
The ADAM-4577 is an advanced peer-to-peer data gateway unit. It
extends traditional RS-232/422/485 interfaces to Ethernet network.
Through networking, you can control and monitor remote serial
devices either over a LAN or over the WAN.
Since the ADAM-4577 is connected through a TCP/IP network, you
will need to know some basic facts about networking in order to get
the server hooked up correctly.
2.1.1
Network Architecture
Traditional serial devices uses RS-232/422/485 interface to issue
commands or transmits data to another one. By doing this, both of
these two devices will be constrained by the length of wire. With the
ADAM-4577, you are now able to communicate with each other via
Internet. Even more, you can connect any networking device dynamically. ADAM-4577 provides 3 networking architectures: Polling, Event
handling, Peer-to-peer. For details, you can refer to chapter 4.

Serial Architecture
The ADAM-4577 provides data modes to meet your needs.
The Data mode provides a certain amount of transparence and
flexibility in transmitting data between two devices.
The data from the serial port of one ADAM-4577 can be automatically
sent to the other networking device, without the need for an intermediate PC. Thus, serial devices will be no longer bundled with operation
system and behave like network devices to send /receive data via
Ethernet.

DIN Rail Mounting
You can mount the ADAM-4577 on a standard DIN Rail. First, using
two screws, attach the metal plate to the DIN Rail bracket. Because the
screw heads are beveled, the tops of the screws will be flush with the
metal plate. Din Rail Mounting Brackets—Orientation of Metal Plates
You can now screw the metal plate with the DIN rail bracket assembly
to the bottom of the server is a more convenient way. Next, use the
remaining screws to put the metal plate on the bottom of the ADAM4577.

2.2.2
Network Connection
There are two ways to use the 10 Base-T Ethernet connector located
on the ADAM-4577 :
1.For Local Area Network (LAN) applications using the
ADAM-4577, you will simply plug one end of your Ethernetcable into
the 10 Base-T connector, and the other end into the hub connected to
your network.
2.When installing and configuring, you will find it convenient to hook
the ADAM-4577 directly to your computer’s Ethernet card. To do this
you will need to use a “crossed-cable”, such as the one supplied with
your server.
Cabling requirements for the Ethernet side
Use an RJ-45 connector to connect the Ethernet port of the ADAM4577 to the network hub. The cable for connection should be Category
3 (for 10Mbps data rate) UTP/STP cable, which is compliant with EIA/
TIA 586 specifications. Maximum length between the hub and any
ADAM-4577 is up to 100 meters (ca. 300 ft).

3.2.4.1
TCP(UDP) Port number
The TCP(UDP) port number represents the source port number , and
the number is used to identify the channel for remote initiating
connections. Range: 1024-65533.
If an unknown caller wants to connect to the system and asks for some
services, they need to define the TCP(UDP) port to carry a long-term
conversation.
Each node on a TCP/IP network has an IP address, and each IP
address can allow connections on one or more TCP port. The well
known TCP port are those that have been defined; for example, port 23
is used for Telnet connections. There are also custom sockets that
users and developers define for their specific needs. The default TCP
(UDP) port of ADAM-4577 is 5200. The example initial 5200 is System
Port, and 5201 is Data Port. But users can adjust them by one's
preference or application.
Note1:
Timing between serial signals (such as DSR, RTS,
and DCD) is not preserved, and the state of such
signals is not readable.

TCP Mode
If you do not want many PCs to have the access right, you can limit at
most 32 PCs to access data from this ADAM-4577. You can list most
32 authorized PCs to allow access data .
UDP Mode
You can also list most 32 authorized PCs to allow access data in UDP
mode. However, Only 8 PCs can access data from ADAM-4577
simultaneously.

Port Mode
1. Selected Port
The default is Port1, DAM-4577 provide one port to connected to
the serial device.
2. Port Mode
The default is Data Mode, The ADAM-4577 provide one mode: Data
mode.
Serial devices that connect to the ADAM-4577 can transmit data to
another networking device
3. Data Idle Timeout
It only appears in TCP mode, The default is 60 seconds. If you want
to keep connection continuously, you can key-in “0”.
Data idle Time is the time period in which the device waits for data. If
the ADAM-4577 does not receive data over an established idle time,
the ADAM-4577 will disconnect temporarily. When the data comes
to the ADAM-4577, it will reconnect automatically. Users do not
need to reconnect.

3.2.4.6
Protocol for Communication
In this option, you can choose either TCP or UDP mode according to
your application.
Due to your TCP or UDP mode choice, it will show different setting
frame of configuration utility. We’ll illustrate the setting base on TCP
or UDP mode.
TCP Mode
Peer for Receiving Data
The option is the setting of another networking device which you
want to connect , including IP address and TCP port. It applies to two
network architectures: Peer-to-peer and Event-handling. It means that
you needn’t fill out any value in this option when you are in Polling
network architecture.
1. IP Addr
Key-in another IP address of networking device which you want to
connect.
2. TCP Port
Key-in another TCP port of networking device which you want to
connect. If you want to connect to the port of another ADAM-4577,
you have to note the following information.
Chapter 3 Installation and Configuration
35
TCP port of ADAM-4577: &&&&
TCP port of ADAM-4577’s port1: &&&& +1
For example:
TCP port of ADAM-4577 that you want to connect: 5220
TCP port of Port 1: 5220 +1=5221
If you want to connect to a PC or any system, you have to key-in the
TCP port of that PC or system.
UDP Mode
UDP Timeout Setting (ms)
The UDP mode is only applied to Polling network architecture. When
you choose UDP mode , Data Idle Timeout option is disable.
1. Response Timeout
It counts after ADAM-4577 transmits out the last data byte to the
device, the period through the device process data and device
transmits data back to ADAM-4577.
As the time is over, ADAM-4577 starts to return data to host PC.
The default is 1000ms, that means ADAM-4577 won’t return data
back to host PC until one second passes

2. Inter Frame Break
ADAM-4577 provides one smart way to reduce inefficient waiting
time.Through Inter Frame Break,ADAM-4577 transmits data more
fficiently.
Inter Frame Break is a good control machine, ADAM-4577 will distinguish whether it transmits back data to host PC by the function. As to
set Inter Frame Break 30 ms, ADAM-4577 won't wait response timeout
1000ms over to transmit data As long as the idle time is longer than 30
ms, ADAM-4577 starts to transmit back data to host PC.
Without setting Inter Frame Break, If the device have transmitted out
the data before response timeout is over,ADAM-4577 has to wait
response timeout over to transmit back data to host PC.The transmission way is very inefficient.For solving the problem,you can set Inter
Frame Break value.
ADAM-4577 will cause efficient network environment with Inter Frame
Break function ADAM-4577 utility default is zero,it means the time of
ADAM-4577 transmits data back to host PC only depends on Response Timeout.
As follows ,we will compare the data time from two case. One is we
don’t set any Inter Frame Break, another is setting Inter Frame Break.
Through the comparison, you can see the effectiveness of setting
Inter Frame Break.
Case1 :
Assume the transmitted data spends 600 ms

Response timeout = 1000 ms
Inter Frame Break = 0 ms

Comparing the difference of the two case, case 2 only wastes 30 ms
but saves 370 ms comparing to case1. We see clearly that if we set
Inter Frame Break, we could save waiting time. ADAM-4577 transmit
data to Host PC at once as Inter Frame Break time is over.
