6 ADAM-4577 User’s Manual

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 dynami-

cally. ADAM-4577 provides 3 networking architectures: Polling, Event

handling, Peer-to-peer. For details, you can refer to chapter 4.
