ADAM-4570/4571 & EDG-4504 User Manual 6

Chapter 2 Getting Started

In this chapter, you will be given an overview of the EDG series hardware

installation procedures.

2.1 Understanding the Advantech EDG Series

The EDG series is an advanced data gateway unit. It extends traditional

COM ports of a PC with access over a TCP/IP network. Through net-

working, you can control and monitor remote serial devices either over a

LAN or over the WAN.Since the EDG series 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 port communication uses a COM port board that slides

into one of the slots at the back of your PC. In this case, only the com-

puter containing the board can access the serial port. With the EDG

series, you are now able to access the COM port from a distance through

local area network. The EDG series can be integrated within the network

architecture of any protocol. Note, all serial devices which are connected

to the port must have the same protocol running and the same trans- mis-

sion speed. Connect devices running different protocols to different ports

of the EDG series.

2.1.2 Secure Communication

Advanced multiple security features protect the system and make data

more private and secure. The ADAM-4570S/4571S guards your network

and data by multiple security protections: T-DES (Triple Data Encryption

Standard, which is specified in FIPS PUB 46-2 and American National

Standard X9.25) strong encryption, PKCS#5 (Password-based Crypto-

graphic Standard #5), and IP address authorization.

We apply T-DES using three blocks (8 bytes for each block) for plain text

3-time calculation and PKCS#7 for data padding when block of the plain

text isn’t enough for 8 bytes. We apply PKCS#5 algorithm to turn user-

defined password into a unique key by means of a hash algorithm. Users

only need to specify a pass- word when configuring ADAM-4570S/

4571S in utility. This prevents important data from being accessed by

unauthorized users.
