Moxa Embedded Ethernet
Switch Module EOM-104 Series
Quick Installation Guide
Third Edition, October 2009
1. 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.

3. 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.
4. 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 IPaddress.
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.
