1: Introduction
1.1 Overview
The HelloDevice Super 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 SS100 is a versatile serial-Ethernet communication device. The SS100 supports variety of the
serial communication types such as RS232, RS422 or RS485 allowing virtually any asynchronous
serial device to be accessed over a network.
As for the Internet connectivity, the SS100 supports open network protocols such as TCP/IP, UDP and
PPPoE (PPP-over-Ethernet) allowing serial devices to be accessed over DSL-based broadband
network orconventional LAN (Local Area Network) environment through the 10/100 Mbps (10Base-T,
100Base-TX) ethernet interface.
The SS100 provides the full-featured management functions such as status monitor, remote reset,
error log monitor and firmware upgrade using Telnet, serial console port or Web browser under the
password protection support. In addition, the SS100 provides IP address filtering function to protect
unintentional data streams to be transmitted to the serial device, and public key cryptography based
SSL data encryption to promise secure data communication. The SS100 also has the SNMP(Simple
Network Management Protocol) agent supporting SNMP v1 and v2 protocols, and Dynamic DNS client
for updatinguser’shostname account offered by various service provider.
The SS100 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

1.4 Terminologies and acronyms
The Internetworking related terminologies used frequently in this manual are defined clearly to help
your better understanding of the SS100.
MAC address
On a local area network or other network, the MAC (Media Access Control) address is the computer's
unique hardware number. (On anEthernet 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 SS100 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
Aseries 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.

2.3. Accessing Console Port
There are two ways to access console port of the SS100 depending on whether the user is located at
a local site or a remote site.
-Serial console:
Local userscan connect directly to the serial console port on the rear side of the SS100 using
serial console cable (null-modem cable).
Note that Data/Console switchmust be pushed to the Console side.
-Remote console:
Remote userscan make a telnet connection to the remote console port (port 23) of the SS100via
TCP/IP network.
Both methods require the user to log into theSS100 in order tocontinue.
Note:
Configuration based on web browser interface is discussed in chapter 10 Management through the
Web Browser Interface.

2.3.2 Using Remote console
The static IP address of the SS100 must be assigned before userscan access the remote console
port (See IP Address Configuration in chapter 3 for details). Remote console access function is
optional, and can be disabled in the remote access option on the menu. This is useful when users
don't want others to modify the existing configuration (See Remote Host Access Control in section
5.1 for details). Up to three users can log into the remote console port of the SS100 simultaneously.
When multiple remote consoles are opened, first opened console has a right to change parameter
values while the others have right only to read parameter values. If the serial console is opened first,
all of the remote telnet consoles do not have a right to update parameter values. If the serial console is
opened after one of remote consoles is opened, serial console do not have a right to update
parameter values until the remote console having read/write permission is closed. The port number for
the remote console is 23, which is a TCP port number assigned for Telnet.
Note:
Abnormal closing of remote telnet console which has read/write permission may block another
opening of telnet or serial console which want to have read/write permission for a while. After 3
minutes from the abnormal closing, SS100 will close that abnormally closed connection.
1) Run a telnet program or a program that supports telnet functionssuch as TeraTerm-Pro or
HyperTerminal. The target IP address and the port number should be those of the SS100. If
required, specify the port number as 23. Type the following command in the command line
interface of your computer.
telnet 192.168.1.254
Or run a telnet program with parameters as follows.
