Overview
The EOM-104 Series Ethernet switch module provides an easy,
cost-effective, and integrated solution for device manufacturers to embed
an Ethernet switch module into an existing product for enhanced
performance and reliability.
The module supports 10/100 Mbps Fast Ethernet, and comes with Turbo
Ring’s fast recovery time of under 20 ms built in. The EOM-104 Series also
provides a rich set of peripherals (e.g., GPIO programming pins and DIP
switches to enable Turbo Ring) and is an ideal solution for embedded
Ethernet applications.
Package Checklist
The EOM-104 Series Evaluation Kit package contains the following items:
•EOM-104 series module
•EOM-104 series evaluation board
•Universal power adaptor
•2 power cords
•Null modem serial cable
•Cross-over Ethernet cable
•Accessories pack
•Quick installation guide (printed)
•Warranty card
Note: Please notify your sales representative if any of the above items are
missing or damaged.
First-Time Installation and Configuration
Before installing the EOM-104 Series, please check to make sure that all
items in the Package Checklist are in the box.
Hardware Installation Procedure
Step 1: Plug the EOM-104 Series into the evaluation board.
Plug the EOM-104 Series module into the sockets on the top of the
evaluation board
Step 2: Connect the power source to the evaluation board.
Connect the 12 VDC power line to the evaluation board’s power jack.
Step 3: Connect the network cable to the evaluation board.
Use the RJ45 Ethernet cable to connect the Ethernet port on the
evaluation board to an Ethernet network for evaluation.
Step 4: Set up the computer’s IP address.
In a Windows environment, the IP address can be changed in the TCP/IP
Settings window. Select an IP address on the same subnet as the
EOM-104 Series. Since the default IP address of the EOM-104 is
192.168.127.253, and the subnet mask is 255.255.255.0, you should set
the IP address of the computer to 192.168.127.xxx.
Step 5: Configure the EOM-104 Series.
Please refer to EOM-104 Series User’s Manual.
