2.1 Understanding EDG-4508+ and EDG-4516+ EDG-4508+ and EDG-4516+ 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+ and EDG-4516+ are connected with the TCP/IP proto-
col, you will have to know fundamental facts about Ethernet networking
to get the server setup correctly.
To allow for easier configuration, we provide several system configura-
tion methods such as Configuration Utility, Web Configuration and Con-
sole mode Configuration. More details will be available in the following
chapters.
