1: Introduction
1.1 Overview
The HelloDevice LS100W allows you to Wireless-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 wireless network.
The LS100W is a most cost effective one port serial wireless LAN communication device. The
LS100W supports RS232 serial communication allowing virtually any asynchronous serial device to be
accessed over wireless network.
As for the Internet connectivity, the LS100W supports open network protocols such as TCP/IP
allowing serial devices to be accessed over 802.11b wireless LAN environment.
The LS100W provides the management console using Telnet and serial console port under the
password protection support. And the LS100W also provides the management function using the
HelloDevice Manager Software Utility.
The LS100W 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 LS100W.
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 LS100W has the MAC address of 000B-6B-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/s erver rela tionship. F or
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 LS100W 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 LS100W.
- 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 LS100W 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
2.1 Panel Layout
The LS100W has 5 LED indicator lamps for status display. The top two lamps indicate the status of
system power and operation readiness. The next lamp down indicates the receive and transmit status
of the serial port for data communication. The final two lamps indicate the IEEE802.11b Wireless LAN
connection and its activity, respectively. Table 2-1 describes the function of each LED indicator lamp.

2.2 Connecting the Hardware
This section describes how to connect the LS100W to the serial device for initial testing.
- Connect a power source to the LS100W.
- Connect the LS100W to a serial device through serial data cable.
2.2.1 Connecting the Power
Connect the power jack to the LS100W power plug using the DC power adapter included in the
package. If power is supplied properly, the [Power] LED lamp on the LS100W front panel will remain
solid red.
Figure 2-2. Connecting the Power to the LS100W
2.2.2 Connecting to the Wireless LAN
There is built-in 802.11b Wireless LAN module in the LS100W. When power is connected correctly,
the module will automatically search for the Wireless LAN access point, and then try to connect to the
LAN access point. If the Wireless LAN cable is properly connected to the Wireless LAN access points,
the LS100W will have a valid connection to the Wireless LAN network and indicates that valid
connection with the following indications:
- The [Link] LED lamp on the LS100W front panel remains solid orange.
- The [Act] LED lamp on the LS100W front panel continuously blinks to indicate the transfer of the
incoming and outgoing Wireless LAN packets.
13
For users to connect the LS100W to a Wireless LAN access point in their environment, they must first
set the corresponding information on the LS100W, such as the SSID of the Wireless LAN access point.
Please refer to the Wireless LAN Settings section in Chapter 3 for the various param eters needing to
be set for Wireless LAN connection.
2.2.3 Connecting to the Device
Connect the serial data cable to the LS100W and the serial device as shown below. Ensure that
power has been correctly supplied to both the serial device and the LS100W.
Figure 2-3. Connecting a Serial Device to the LS100W
2.3. Accessing Console Port
There are two ways to access console port of the LS100W 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 LS100W using serial
console/data cable (null-modem cable). The serial port of the LS100W 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 LS100W
via TCP/IP network.
Both methods require the user to log into the LS100W in order to continue.
14
2.3.1 Using Serial Console
1) Connect the one end of the serial console cable to the serial port of the LS100W.
Figure 2-4. Connecting a serial console cable to the LS100W
2) Connect the other end of the cable to the serial port of user’s computer.
3) Slide Data/Console switch to Console side.
Figure 2-5. Data/Console switch of the LS100W
4) Run a terminal emulator program such as HyperTerminal. Set up the serial configuration
parameters of the terminal emulation program as follows:
9600 Baud rate, Data bits 8, Parity None, Stop bits 1, No flow control
