Chapter 2 Getting Started
This chapter includes information about installing EDG-4508(R)+ and
EDG-4516(R)+ The following covered:
• Understanding the EDG-4508(R)+ and EDG-4516(R)+
• Connecting Hardware
• Configuration Utility and COM port mapping Utility installation
2.1 Understanding EDG-4508/4516(R)+ Modules
EDG-4508(R)+ and EDG-4516(R)+ are advanced Ethernet data gateway
units. They extend traditional COM ports of a PC to Ethernet access.
Through Ethernet networking, users can control and monitor remote
serial devices and equipment over LAN or WAN. Since EDG-4508(R)+
and EDG-4516(R)+ are connected with the TCP/IP protocol, you will
have to know fundamental facts about Ethernet networking to get the
server setup correctly. To allow for easier configuration, we provide sev-
eral system configuration methods such as Configuration Utility, Web
Configuration and Console mode Configuration. More details will be
available in the following chapters.
EDG -4508(R)+ and EDG-4516(R)+ come with a virtual COM driver
that transmits all signals intact. Your existing COM-based applications
can be preserved, without in additional modification. EDG-4508(R)+
and EDG-4516(R)+ also provide various Socket modes: TCP/UDP con-
trol mode and TCP/UDP data mode. The main different of TCP and UDP
protocol is that TCP guarantees delivery of data by requiring the recipient
to send and acknowledge to the sender. UDP doesn't require this verifica-
tion.
Traditional serial devices use RS-232/422/485 interface to issue com-
mands or transmits data to another one. Many of these devices will be
constrained by the length of wire. With the EDG-4508(R)+ and EDG-
4516(R)+, you are now able to communicate with each other via Internet.
Even more, you can connect any networking device dynamically.
