1: Introduction
1.1 Overview
The HelloDevice Lite Series allows you to network-enable a variety of serial devices that were not
originally designed to be networked. This capability brings the advantages of remote management and
data accessibility to thousands of serial devices over the network.
The LS100 is a most cost effective one port serial-Ethernet communication device. The LS100
supports RS232 serial communication allowing virtually any asynchronous serial device to be
accessed over a network.
As for the Internet connectivity, the LS100 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 LS100 provides the management console using Telnet and serial console port under the
password protection support. And the LS100 also provides the management function using the
HelloDevice Manager Software Utility.
The LS100 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 LS100.
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 LS100 has the MAC address of 00-0195-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 LS100 in the first place.
- 2.1 Panel Layout explains the panel layout and LED indicators.
- 2.2 Connecting the Hardware describes how to connect the power, the network, and the serial
device to the LS100.
- 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 LS100 to configure and view
parameter values and status.
Following items are pre-required to get started.
- One DC power adapter (included in the package).
- One serial console cable for configuration (included in the package).
- One RS-232 serial cable for connecting the RS-232 serial device.
- One PC with Network Interface Card (hereafter, NIC) and/or one RS232 serial port.
- Terminal emulation program running on the PC
- One Ethernet cable
2.1 Panel Layout
The LS100 has five LED indicator lamps for status display. Two lamps on the upper side indicate
statuses of 10 Base-T Ethernet Link and Act. Next lamp indicates statuses of receive and transmit of
the serial port for data communication. Next two lamps indicate the system running status and the
system power-on status. Table 2-1 describes function of each LED indicator lamp.
Table 2-1. LED indicator lamps

2.2 Connecting the Hardware
This section describes how to connect the LS100 to serial device for the first time test.
- Connect the power to the LS100
- Connect the Ethernet cable between the LS100 and Ethernet hub or switch
- Connect the serial data cable between the LS100 and a serial device
2.2.1 Connecting the Power
Connect the power jack to the LS100 power jack using DC power adapter included in the package. If
the power is properly supplied, the [Power] lamp of the LS100 will maintain solid red.
Figure 2-2. Connecting the power to the LS100
2.2.2 Connecting to the Network
Connect the one end of the Ethernet cable to the LS100 10Base-T port and the other to the Ethernet
network. If the cable is properly hooked up, the LS100 will have a valid connection to the Ethernet
network by indicating:
- [Link] lamp of the LS100 maintains solid green
- [Act] lamp continuously blinks to indicate the incoming/outgoing Ethernet packets
If any of the above does not happen, the LS100 is not properly connected to the Ethernet network.

Figure 2-3. Connecting a network cable to the LS100
2.2.3 Connecting to the Device
Connect the serial data cable between the LS100 and the serial device. If necessary, supply the
power to the serial device attached to the LS100.
Figure 2-4. Connecting a serial device to the LS100

2.3. Accessing Console Port
There are two ways to access console port of the LS100 depending on whether the user is located at
a local site or a remote site.
- Serial console:
Local users can connect directly to the serial console port of the LS100 using serial console/data
cable (null-modem cable). The serial port of the LS100 is used as the console port as well as the
data port. To use the serial port as the console port, slide Data/Console switch to the Console
side.
- Remote console:
Remote users can make a telnet connection to the remote console port (port 23) of the LS100 via
TCP/IP network.
Both methods require the user to log into the LS100 in order to continue.
2.3.1 Using Serial Console
1) Connect the one end of the serial console cable to the serial port of the LS100.
Figure 2-5. Connecting a serial console cable to the LS100
2) Connect the other end of the cable to the serial port of user’s computer.
3) Slide Data/Console switch to Console side.
