1: Introduction
1.1 Overview
The NEMO10 allows you to network-enable a variety of serial devices that were not originally
designed to have network-capability. This capability brings the advantages of remote management
and data accessibility to thousands of serial devices over the network.
The NEMO10 is DIL (Dual-In-Line) package, cost-effective single-port serial-Ethernet communication
module. The NEMO10 supports RS232 serial communication allowing virtually any asynchronous
serial device to be accessed over a network. Its compact size enables users to easily develop their
network-enabled device by simple on-board installation. For easier evaluation, the NEMO10-SK, the
starter’s kit is provided. In the NEMO10-SK, there are several additional items for evaluation, such as
carrier board for testing the NEMO10 module, CD-ROM for the software and the power-supply.
As for the Internet connectivity, the NEMO10 supports open network protocols such as TCP/IP
allowing serial devices to be accessed over broadband network or conventional LAN (Local Area
Network) environment.
The NEMO10 provides the management console using Telnet and serial console port under the
password protection support. And the NEMO10 also provides the management function using the
HelloDevice Manager Software Utility.
The NEMO10 was designed to accommodate the unique requirements of the Retail POS, Security,
Automation and Medical marketplaces.
Parts of this manual assume the knowledge on concepts of the Internetworking protocols and serial
communications. If you are not familiar with these concepts, please refer to the standards or the
documentation on each subject.

1.4 Terminologies and Acronyms
The Internetworking related terminologies used frequently in this manual are defined clearly to help
your better understanding of the NEMO10.
MAC address
On a local area network or other network, the MAC (Media Access Control) address is the computer's
unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.)
It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique
Identifier) number and 6-digit hardware identifier number. The NEMO10 has the MAC address of 00-
01-95-xx-xx-xx, which is labeled on the bottom side of the external box.
Host
A user’s computer connected to the network
In Internet protocol specifications, the term "host" means any computer that has full two-way access to
other computers on the Internet. A host has a specific "local or host number" that, together with the
network number, forms its unique IP address.
Session
A series of interactions between two communication end points that occur during the span of a single
connection
Typically, one end point requests a connection with another specified end point and if that end point
replies agreeing to the connection, the end points take turns exchanging commands and data ("talking
to each other"). The session begins when the connection is established at both ends and terminates
when the connection is ended.
Client/Server
Client/server describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
A server is a computer program that provides services to other computer programs in the same or
other computers, whereas a client is the requesting program or user in a client/server relationship. For
example, the user of a Web browser is effectively making client requests for pages from servers all
over the Web. The browser itself is a client in its relationship with the computer that is getting and
returning the requested HTML file. The computer handling the request and sending back the HTML file
is a server.

2: Getting Started
This chapter describes how to set up and configure the NEMO10 in the first place by using the test
bed included in the NEMO10-SK.
-2.1 Board layout and connectors explains the board layout for the NEMO10 and the test bed for
it and the connectors.
-2.2 Connecting the Hardware describes how to connect the power, the network, and the serial
device to the NEMO10.
-2.3 Accessing Console Port describes how to access the console port using a serial console at a
local site or telnet console at a remote site.
-2.4 Command Usages described how to use command set of the NEMO10 to configure and
view parameter values and status.
Following items are pre-required to get started.
- One DC power adapter (included in the NEMO10-SK package).
- One serial console cable for configuration (included in the NEMO10-SK package).
- One PC with Network Interface Card (hereafter, NIC) and/or one RS232 serial port.
- Terminal emulation program running on the PC
- One Ethernet CAT5 cable

2.1.1 The NEMO10 module
The NEMO10 is a DIL (Dual-In-Line) package module for on-board installation. It provides the external
interface pins for power, switch, LED, UART and the RJ45 connector for Ethernet. The pin-out of the
NEMO10 is described in the Table 2-1. Figure 2-1 shows the layout of the NEMO10.
