1.1 PRODUCT DESCRIPTION
This manual presents installation and operating instructions for the
MDS entraNET 900 system. It is for use by professional installers who
are expected to install, operate, and perform basic maintenance on the
system.
The MDS entraNET 900 system is an easy-to-install wireless solution
that supports long range Serial and Ethernet data transmission at speeds
up to 115.2 kbps. The system includes an Access Point transceiver (AP)
and two types of Remote transceivers—Serial or Ethernet. These units
serve a variety of network configurations. Figure 1-1 shows each model
of the entraNET family.

MDS entraNET units are housed in compact and rugged die-cast cases.
They need only be protected from direct exposure to the weather. The
transceivers are supplied with optional flat surface or 35 mm DIN rail
mounting brackets, depending on customer requirements.
Basic installation typically employs an omni-directional antenna at the
Access Point location and a directional antenna at each associated
Remote. The antenna is a vital link in the system and must be chosen and
installed correctly. Refer to
INSTALLATION
on Page 103 for guidance
on choosing proper sites and antennas.
For basic services, you simply hook up an antenna, connect your
Ethernet LAN to the transceiver’s
port, apply primary power, check
LAN
and set a few operating parameters as necessary and you are done. No
license is required for operation in the U.S.A., Canada, and many other
countries.
Secure Operation
Data network security is a vital issue in today's wireless world. The
MDS entraNET’s design provides multiple tools to help you build a network that minimizes the risk of eavesdropping and unauthorized access.
MDS 05-4055A01, Rev. A MDS entraNET 900 System Guide (Preliminary) 3
Some are inherent in the radio's operation, such as the use of
spread-spectrum transmission; other techniques include data encryption, enabling/disabling remote access channels, and password protection.
Remember, security is not a one-step process that can be simply turned
on and forgotten. It must be practiced and enforced at multiple levels,
24 hours-a-day and 7 days-a-week. Section 1.4 on Page 10 contains
additional information about entraNET’s security tools.

Features
The transceivers are designed for frequency-hopping spread-spectrum
operation in the license-free 900 MHz band. They can provide reliable
communications up to distances of 30 miles (50 km) or more under
favorable conditions. The units employ digital signal processing (DSP)
techniques for high performance operation, even in the presence of
weak signals or interference.
Users with a mixture of equipment having Ethernet and serial data interfaces can choose a combination of both types of remotes on the same
cell or Access Point. This flexibility allows the transceiver to provide
services in data networks that are on a path from legacy
serial/EIA-232-based hardware to the faster and more easily interfaced
Ethernet world.
Configuration, commissioning, troubleshooting and other maintenance
activities can be done locally or remotely. Four different modes of
access are available: local RS-232 console, local or remote IP access
through Telnet, web browser access, and via SNMP. The text-based
interfaces (RS-232 console and Telnet) are implemented in the form of
easy-to-follow menus, and the terminal server configuration includes a
“wizard” to help you set up the units correctly.
The MDS entraNET 900’s design makes the installation and configuration easy, while allowing for changes in the future.
• Long Range—30 miles (50 km) over favorable terrain, with sufficient antenna height in a point-to-multipoint configuration
• Industrial-Grade Product—Extended temperature range for
trouble-free operation in extreme environments
• Robust Radio Communications—Designed to operate in
high-interference environments
• Robust Network Security—Prevents common attack schemes
and hardware from gaining access or control of network. Common attack events are logged and reported by alarms.
• Fast, 115.2 kbps data speed—Much faster than 9.6 kbps radios
• Plug-and-Play Connectivity—Ethernet bridge configuration
option requires very little setup
• Serial Ports—Gateway for serial interface based equipment to
IP/Ethernet networks with embedded terminal server

1.1.1 Model Offerings
The MDS entraNET 900 comes in two primary models—an Access
Point and a Remote. In addition, two types of Remotes are available—
an Ethernet Remote, and a Serial Remote. Table 1-1 summaries the different interface abilities for each type.
An Ethernet remote will serve only one MAC address, even if a bridge
or hub is used.

1.2 APPLICATIONS
The following sections give descriptions of typical entraNET installations. Most installations will require planning by a network manager.
1.2.1 Long Range Wireless LAN
The wireless LAN is the most common application of the entraNET 900
system. It consists of a central control station (Access Point) and one or
more associated Remote units, as shown in Figure 1-2 on Page 6. A
LAN provides communications between a central WAN/LAN and
remote Ethernet segments. The operation of the radio system is transparent to the computer equipment it is connected to.
The Access Point is positioned at a location from which it can communicate with all of the Remote units in the system. Commonly, this is a
relatively high location on top of a building or communications tower.
Messages are exchanged at the Ethernet level. This includes all types of
IP traffic.
A Remote transceiver can only talk over-the-air to an Access Point (AP)
unit. Peer-to-peer communications between Remotes can only take
place indirectly through the AP. An AP can only talk over-the-air to
Remote units, however two APs can communicate with each other
through their Ethernet connectors utilizing a common LAN/WAN.

1.2.2 Multiple Protocols and/or Services
Prior to the introduction of the entraNET 900, two radios were often
required to service two different types of devices (typically connected to
different SCADA hosts). An entraNET 900 provides this functionality
through a single AP radio. Each of the two groups of remote radios can
be connected via IP to different SCADA hosts, transporting different (or
the same) protocols. Both data streams are completely independent and
the transceiver provides seamless simultaneous operation as shown in
Figure 1-3 on Page 6.

By using a single AP the cost of infrastructure deployment is cut in half,
with only one antenna, one feedline, and one lightning protector
required. Other cost reductions come from the system as a whole,
6 MDS entraNET 900 System Guide (Preliminary) MDS 05-4055A01, Rev. A
including reduced management requirements via the MDS NETview
MS application. Finally, entraNET offers a nearly unlimited potential
for future applications that run over IP and Ethernet.
1.2.3 Upgrading Older Wireless Network with
Serial Interfaces
Millions of wireless data products have been sold in the last two decades
for licensed and license-free operation, many of them manufactured by
Microwave Data Systems. There are several ways that these systems can
benefit from the more flexible MDS entraNET 900 equipment—more
flexible serial and Ethernet interfaces, and higher data throughput.
MDS entraNET 900 units are well suited to replace leased or dial-up
lines, or existing 900 MHz data transceivers by taking advantage of the
transceiver’s serial and Ethernet interfaces.
Replacing Legacy Wireless Products
In most cases, legacy radio transceivers supporting serial-interface
equipment can be replaced with MDS entraNET 900 units with little or
no special configuration. This equipment can be connected to MDS
entraNET 900 units through the
COM1
DB-9 cable wired for EIA-232 signaling. The
or
COM2
port with a DB-25 to
COM2
port supports all
standard EIA-232 signaling and acts as a data-terminal equipment
device (DTE).
Several previous MDS-brand products had non-standard signal lines on
their interface connectors; for example, to control the unit sleep function. These special functions are not provided nor supported by the
MDS entraNET 900 unit at this time. Always consult the legacy equipment manual(s) for interface pinout information prior to making connections.
Supplement legacy wireless network with IP services
The MDS entraNET 900 Dual Gateway model can support up to two
serial devices and one Ethernet connection at the same time. The serial
interfaces (COM1 and COM2) operate in two different modes: Connectionless serial-to-serial (UDP) and connection-oriented IP-to-serial
(TCP).
In the UDP (connectionless serial-to-serial) mode, the transceiver supports point-to-multipoint serial-port to serial-port connectivity. In the
TCP (connection-oriented IP-to-serial) mode, the transceiver supports
point-to-point Ethernet/IP to serial port connectivity.

URING THE SERIAL INTERFACES”

1.3 NETWORK DESIGN
CONSIDERATIONS
1.3.1 Extending Network Coverage with Repeaters
What is a Repeater System?
A repeater works by re-transmitting data from outlying remote sites to
the Access Point and vice-versa. As with any other store-and-forward
device, it introduces additional end-to-end transmission delay but provides longer-range connectivity.
In some geographical areas obstacles can make communications difficult. These obstacles commonly are large buildings, hills or dense
foliage. These obstacles can often be overcome with a repeater station.
The geographic location of a repeater station is especially important. A
site must be chosen that allows good communication from the repeater
to
both
the Access Point and outlying remote sites. This location is often
on top of a hill, or other elevated terrain from which both sites can be
“seen” by the repeater station antennas. A detailed discussion on the
effects of terrain is given in Section 5.1.2,
Page 105).
Site Selection
(beginning on
Using a Remote as a Store-and-Forward Repeater
A wireless network can be extended through the use of an alternate
arrangement using the Access Point as a repeater to re-transmit the signals of all stations in the network. The repeater is a standard transceiver
configured as an Access Point. (See Figure 1-4.)

1.3.2 Protected Network Operation through Multiple
Access Points
Although MDS entraNET 900 units have a very robust design and have
undergone intensive testing before shipment it is possible for isolated
failures to occur. Down time can be further reduced by using some, or
all, of the following configurations.
8 MDS entraNET 900 System Guide (Preliminary) MDS 05-4055A01, Rev. A
In a point-to-multipoint scenario, the Access Point services multiple
remotes. A problem in the Access Point will have an effect on all
remotes, since none will have access to the network. When operation of
the network does not tolerate any down time, it is possible to set up a
protected configuration for the Access Point to greatly reduce the possibility of this happening.
Two or more Access Points can be configured with the same Network
Name and kept active simultaneously, each with its own independent
antenna. In this scenario, Remotes will associate with either one of the
available Access Points. In case of a failure of one of the AP’s, the
Remotes will quickly associate with another of the remaining Access
Points re-establishing connectivity to the end devices.
Access Points are unaware of the existence of another co-located AP.
This is because the hopping algorithm uses
both
the Network Name
and
the Wireless MAC address of the AP to generate the hopping pattern.
For this reason, multiple AP’s can coexist—even if they use the same
network name. The co-located AP’s will be using different hopping patterns and frequencies the great majority of the time. Although some collisions will occur, the wireless-MAC is built to tolerate and recover from
such occurrences with minimal degradation.
1.3.3 Co-locating Multiple Networks
Many wireless networks can operate in relatively close physical proximity to one another providing reasonable measures are taken to assure
the radio signal of one Access Point is not directed at the antenna of the
second Access Point.
The Network Name and the association process
The Network Name is the foundation for building individual
MDS entraNET 900 networks. It is part of a beacon signal broadcast by
the Access Point (AP) to any Remote units with the same Network
Name. Remotes that join the network are referred to as being “associated” with the Access Point unit.
Multiple APs with the same Network Name should be avoided unless a
redundant system is being deployed. Using the same Network Name in
multiple APs may result in Remotes associating with undesired APs and
preventing data exchange from occurring.
The use of a different Network Name does not guarantee an interference-free system. It does however, assure that only data destined for a
unique network is passed through to that network.
Co-Location for
Redundancy
You can co-locate Access Points at one location for load-sharing or
redundancy, provided they have the same Network Name. Provide some
vertical separation between the antennas to minimize RFI between
them.
MDS 05-4055A01, Rev. A MDS entraNET 900 System Guide (Preliminary) 9
Co-Location for
Multiple Networks
It may be desirable to co-locate Access Points at one location to take
advantage of an excellent or premium location that can serve two independent networks. Each network should have unique Network Name
and each AP unit’s antenna should be provided as much vertical separation as is practical to minimize RFI.
NOTE: All radios are shipped with the Network Name as
“Not Programmed.” The Network Name must be programmed
in order to pass data and begin normal operations.
Can radio-frequency interference (RFI) disrupt my Network?
When multiple MDS entraNET 900 networks operate in close physical
proximity to other wireless networks, individual units may not operate
reliably under weak signal conditions and may be influenced by strong
radio signals in adjacent bands. This radio frequency interference cannot
be predicted and can only be determined by experimentation. If you
need to co-locate two transceivers, start by using the largest possible
vertical antenna separation between the two AP antennas on the same
support structure. If that does not work, consult with MDS technical
support personnel about other techniques for controlling radio frequency interference between the radios. (See “A W or d About Radio
Interference” on Page 108 for more details.)
1.4 SECURITY TECHNIQUES & TOOLS
Today the operation and management of an enterprise is becoming
increasing dependent on electronic information flow. An accompanying
concern becomes the security of the communication infrastructure and
the security of the data itself.
The MDS entraNET 900 is capable of dealing with many common security issues. Table 1-2 profiles security risks and how the MDS entraNET
900 provides a solution for minimizing vulnerability.

2.1 INTRODUCTION
The MDS entraNET 900 is equipped with an embedded management
system that is accessible through different data interfaces. These include
the
COM1 (serial) port, the LAN (Ethernet) port and over the wireless net-
work. Essentially the same capabilities are available through either of
these paths.
You have a choice of using three common communications tools—a
computer terminal-emulator through the
browser through the
LAN (Ethernet) port. You must know the unit IP
address and the entraNET Management System password and user
name to use the LAN port access.
The transceiver also supports SNMP-based management tools such as
Microwave Data Systems’ NETview MS™. NETview MS provides a network-wide management tool using a graphical user interface (GUI). For
support of other software, a set of MIB files is available for download
from the Microwave Data Systems’ Web site at
data.com/service/technical/support/downloads/. A brief summary of
SNMP commands can be found at SNMP Configuration section on
Page 28.

The entraNET Management System and its functions are divided in this
guide into five functional groups that are listed below.
• Section 2.3, CONFIGURING NETWORK PARAMETERS
(beginning on Page 27)
• Section 2.4, CONFIGURING RADIO PARAMETERS (begin-
ning on Page 28)
• Section 2.5, CONFIGURING THE SERIAL INTERFACES
(beginning on Page 32)
• Section 2.7, PERFORMANCE VERIFICATION (beginning on
Page 44)
• Section 2.8, MAINTENANCE (beginning on Page 58)
Each of these sections has a focus that is reflected in its heading. The
section you are now in will provide you with information on connecting
to the entraNET Management System, how to navigate through it, and
how it is structured, and how to perform some top-level configuration
tasks.

2.1.2 Differences in the User Interfaces
There are slight differences in navigation, but for the most part, the content is the same. You will find a few differences in capabilities—the
communications tool is driven by limitations of the access channel.
Below are samples of the Starting Information Screen seen through a
terminal and a Web-browser.

2.1.3 Accessing the Embedded Management
System
The menu-based management system provides access to view and configure many unit parameters and provides you with basic diagnostic and
maintenance tools. There are several tools that can be used to gain
access to the entraNET Management System.
• Terminal-Emulator—Use a terminal emulator program on
your PC, such as HyperTerminal, connected directly to the
MDS entraNET 900
• Telnet—Text-based access to the Management System through
a network connection (AP only).
• Web Browser—Connect to the entraNET units using a Web
browser on a local PC connected directly to the transceiver’s
LAN port or associated network (AP only).
The following are detailed procedures for connecting to the embedded
Management System.
COM1 port via a serial cable.
Procedure with
Terminal Emulator
Procedure with
Telnet (AP only)
a. Connect a computer’s serial communications port to the trans-
ceiver’s
COM1 Port connector.
b. Launch a terminal emulator program, such as HyperT erminal, on
the computer. Configure it to 19,200 bps data rate, 8-bit characters, no parity, one stop bit, and no flow-control. Use ANSI or
VT100 emulation.
c. Press the
ENTER key. A login screen will be displayed that will
require a user name and password to access the Management
System. (User = entraNET; default password =
admin)
The radio will respond with a login screen, followed by the
start-up screen similar to Figure 2-5 on Page 22.
NOTE: If the transceiver is powered-up or rebooted while connected
with a terminal, you will see a series of pages of text information relating to the booting of the unit’s microcomputer. Wait
for the initial entraNET MS login screen before proceeding.
The boot process takes approximately 30 seconds.
a. Connect a personal computer’s Ethernet port to the LAN Port
connector on the AP transceiver using an Ethernet crossover
cable or connect the AP to the network. (See Figure 3-3 on
Page 81 for location.) The
LAN LED will light up.
b. Start the Telnet program on your computer targeting the IP
address of the transceiver to which you are connected and press
the
ENTER key.
For example, in Windows: Start>Run>Telnet
MDS 05-4055A01, Rev. A MDS entraNET 900 System Guide (Preliminary) 19
NOTE: Do not use the default IP address (192.168.1.1) if there
are multiple transceivers on the same network set with the
default address.
c. The transceiver will respond with a login screen. Enter your
password and press the
ENTER key. (Default = admin)
The entraNET responds with the start-up menu screen.
(Figure 2-6 on Page 23)
Procedure with Web
Browser (AP only)
a. Connect a personal computer’s Ethernet port to the LAN Port
connector on the transceiver using an Ethernet crossover cable.
(See Figure 3-3 on Page 81 for location.) The
LAN LED will
light up.
b. Launch a Web-browser (HTTP) program, such as Microsoft’s
Internet Explorer™, on your computer.
c. Type in the radio’s IP address. For example
the
ENTER key. (Default address = 192.168.1.1)
192.168.1.1 and press
d. A login screen will be displayed that will require a user name
and password to access the Management System.
(Defaults: user = entraNET; password=
admin)
e. The transceiver responds with the startup menu screen.
(See Figure 2-6 on Page 23.)
NOTE: If the default address of 192.168.1.1 does not work, use the
terminal-emulator procedure to communicate with the unit
through the COM1 port. The current IP address will be
displayed on the Starting Information Screen (Figure 2-6 on
Page 23).
2.1.4 Navigating the Menus
Navigating with a Web browser is straightforward with a framed page.
The primary navigation menu is permanently located in the left-hand
window. The right-hand window displays the current menu item.
The text-based interface, accessible through Telnet or terminal emulator, uses a traditional multi-layered text menu system. To move further
down a path in the menu tree, type the letter key to the left of the menu
item. You will automatically move to the associated screen. In most
cases, use the
In general, the top portion of the screen shows read-only information
with no user selection letter. The bottom portion of the screen contains
parameters that can be selected for further information, alteration of
values, or to navigate to other menus.
20 MDS entraNET 900 System Guide (Preliminary) MDS 05-4055A01, Rev. A
ESCAPE key to move back up a level.
When you arrive at a screen with user-controllable parameter fields, you
select the menu item by keying in an associated letter. If there is a user
definable value, the field will clear to the right of the menu item and you
will be allowed to type in the value you wish to use. Follow this action
by the
your mind before using the
ENTER key to save the changes. If you make a mistake or change
ENTER key, press ESCAPE to restore the pre-
vious value.
In some cases, when you type a letter to select a parameter, you will see
a prompt at the bottom of the screen that says “Choose an Option.” In
these cases, press the keyboard’s
SPACEBAR and you will step through
the available selections. After the desired option appears, press the
ENTER key to save the selection. In some screens, several parameters
may be changed and then saved by a single keystroke. The
ESCAPE key
can be used to cancel the action and restore the previous value.
In most cases, you can press the
ESCAPE key to exit the action without
implementing any changes or to navigate to the next higher level menu.
2.1.5 Logging In and Out of the Embedded
Management System
Logging in via Telnet or a Web Browser
When you use Telnet or a Web browser to communicate with the transceiver, you will need to know the unit’s IP address, the “User Name”,
and “Password” in advance.
With some Web browsers, the User Name, entraNET
it is blank, type in entraNET with a lowercase “i” and capitals N-E-T.
The default user password is
admin in lowercase letters.
NOTE: Passwords are case sensitive. Do not use punctuation mark
characters. Use a maximum of eight characters.
Once the User Name and Password have been entered, press
NOTE: It may be necessary to change your IP access to the local area
network to match the one used by the MDS entraNET 900.
(Defaults: IP–192.168.1.1, Netmask–255.255.0.0) You can
identify or verify the transceiver’s IP address using a
terminal-emulator to communicate with the transceiver
through the COM1 Port and then viewing the Starting Informa-
tion Screen.
will be filled in. If
ENTER.
If you are accessing the entraNET MS via a browser connected to the
LAN port, you will see a sign-in screen similar to the one in Figure 2-5.

the web browser interface. This restriction is done for security reasons—a web browser transmits messages in clear text.
Logging Out of the entraNET Management System
For security reasons, it is best to formally log-out of the entraNET Management System. If you do not formally log out, the session will be terminated within 10 minutes of your last activity with the system.
Web Browser To logout of the entraNET MS with a Web browser, click on the
“Logout” listing in the left hand frame of the browser window. The
right-hand frame will change to a logout page. Follow the instructions
on this Web page.
Telnet From the Main Menu, press “Q” to quit and terminate the session. If you
do not manually log out, your session will time-out after 10 minutes of
no keyboard activity.
Terminal Emulator You do not need to logout from a terminal emulator when connected to
the
COM1 port. You can force a logout by pressing the exclamation
point (!) key to optimize the transceiver’s security. (Note: This only
works from the Starting Information Screen or the Main Menu Screen.)
