Why!
Etherent solutions
¡§Embedded
Internet¡¨ and ¡§Embedded Ethernet¡¨ are hot topics today.
Nowadays the Ethernet protocol becomes the de-facto standard for
local area network. Via Internet, connectivity is occurring
everywhere, from home appliances to vending machines to testing
equipment to UPS¡Ketc. Many embedded designers now face
dilemma of adding Ethernet interface to their products, either for
use with local networks or for connecting to the Internet. Solutions
to this problem include both hardware and software. Connecting via
Ethernet requires a software protocol called TCP/IP. The installed
base of Ethernet networks is huge and growing. Most office building,
factories, and new homes have installed Ethernet network. With
Ethernet, the network is always available. Using Ethernet for
network in industrial area is appealing because the required cabling
is already installed.
Introduction
The
I-7188EX is powered by 80188-40 processor with 512K bytes of static
RAM, and 512K bytes of Flash memory. One serial RS-232 port and one
RS-485 port are provided. Ethernet support is provided by a NE-2000
compatible controller with 16K bytes of on-chip buffer memory and
10Base-T media interface. The I-7188EX also provides 14 user defined
I/O lines. A cost-effective I/O expansion board with A/D, D/A, relay
drivers and protected inputs is available. The I-7188EX also
supports battery back-up SRAM disk board and Flash-Rom board,
providing non-volatile mass storage from 2 megabytes to 64
megabytes.
The
10BASE-T port is equipped with a RJ-45 connector.
The
10BASE-T interface supports max. 100-meter Cable length between
I-7188EX and the network hub.
