Introduction 14
Models 2211 & 2232 Getting Started Guide 1 • Overview
Introduction
The EtherBITS 2211 and 2232 enable 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.
Figure 1. Model 2211 EtherBITS device server
Both devices are cost-effective single-port serial-Ethernet communication devices. The Model 2211 (see
figure 1) connects to the network via 802.11b wireless transmission. The Model 2232 (see figure 2) connects to
the network through an RJ-45 connector. Both devices support RS-232 serial communications that enable vir-
tually any asynchronous serial device to be accessed over a network.
Figure 2. Model 2232 EtherBITS device server
As for the Internet connectivity, the devices open network protocols such as TCP/IP allowing serial devices to
be accessed over broadband network or conventional LAN (local area network) environment.

Glossary 15
Models 2211 & 2232 Getting Started Guide 1 • Overview
The device servers provides a management console, by using Telnet and the serial console port, which is under
password protection. The device servers also provide a management function with the use of the EtherBITS
Manager Software Utility.
The device servers accommodate the requirements of the Retail POS, Security, Automation and
Medical marketplaces.
Note This manual assumes user knowledge of Internetworking protocols and
serial communications
Glossary
This section defines commonly used terms in this manual. These terms are related to Internetworking, and
defined in regards to their use with device server.
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 is the same as the 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 MAC address can be found on the bottom of the
original package.
Host
A user’s computer connected to the network
Internet protocol specifications define host as any computer that has full two-way access to other computers on
the Internet. A host will have 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. If the specified end point
replies, and agrees to the connection, the end points then 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 con-
nection 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 on one or many computers.
The 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 cli-
ent 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.

Introduction
This chapter describes how to set up and configure the device server.
•“Unpacking the device server”—lists the contents of the device server’s shipping container
•“Controls, ports, and indicators”—Explains the layout of the device server controls and LED indicators
•“Connecting the hardware” on page 20—Describes how to connect the power, the network, and the serial
device to the EtherBITS device server.
•“Accessing the Console Port” on page 22—Describes how to access the console port by using a serial con-
sole at a local site or telnet console at a remote site.
•“Command usage” on page 25—Describes how to use command set of the device server to configure and
view parameter values and status.
The following items are required to get started:
•One DC power adapter (included in the package)
