1. Initial Checkout

• Set the equipment up in a tabletop arrangement as described in

EVALUATION, (beginning on Page 15)

.

2 TABLETOP SETUP AND

•Follow all steps to ensure proper cable connections and unit configuration. As a minimum, Access
Points must have the following programmed: IP Address, IP Network identifier, and Radio Network
Address. (RF output power and Password should also be reviewed and set if necessary.) Remote
radios normally require only a Radio Network Address to be set. (Note: The Remote Radio Net­work Address

must

match that of the AP.)

• Connect data equipment to the transceivers. Use LAN/ETH ports for Ethernet systems, or COM2
ports for Serial data systems.

•Verify proper exchange of data communications by viewing the LEDs. The following indications
should be seen on the LED panel within 30 seconds of startup:

2. Endpoint Connectivity (PING) Test—for Ethernet Systems Only

•For Ethernet systems, verify the link integrity between the Access Point and endpoint devices con­nected to Remotes by issuing a

PING

command from the AP. Below is a basic setup diagram for

the PING test. (NOTE: Endpoint devices must have a compatible IP address for this test to work.)

1.2 PRODUCT DESCRIPTION

The entraNET system is an easy-to-install wireless solution supporting
long-range serial and Ethernet data transmission at speeds up to
106 kbps. The system includes an Access Point (AP) transceiver and a
Remote transceiver capable of serial and Ethernet communication.
These radios serve a variety of network configurations. Figure 1-1
shows the two radios.

Figure 1-1. MDS entraNET Transceiver Models

Robust Radio
Operation

MDS entraNET transceivers use an advanced Media Access Controller
(MAC) to ensure network access for stations with data to send. The
MAC permits data to be sent from endpoint devices on an on-demand
basis, preventing over-the-air data collisions and ensuring that data gets
through as intended. MAC functionality eliminates the need for active
polling of Remotes, a key requirement in Report-by-Exception (RBE)
applications.

Rugged Packaging MDS entraNET radios are housed in compact and rugged die-cast cases

that need only be protected from direct exposure to the weather. The
transceivers are supplied with flat surface-mounting brackets or optional
35mm DIN rail brackets, depending on customer requirements.

Simple Installation Basic installation typically employs an omni-directional antenna at the

AP site and a directional antenna at each associated Remote site. The
antenna is a vital link in the system and must be chosen and installed
correctly. INSTALLATION on Page 145 provides guidance on choosing
proper antennas and installation sites.

To establish basic service, connect an antenna, connect an Ethernet
LAN (Local Area Network) to the AP, connect a serial or Ethernet
device to the Remotes, apply power, set a few operating parameters via
a personal computer, and you are done. No license is required for oper­ation in the U.S.A., Canada, and many other countries. Check the regu­lations in your country before placing the radios on the air.

MDS Security Suite Network security is a vital issue in today’s wireless world. The

MDS entraNET system provides multiple tools to help you build a net­work that minimizes the risk of eavesdropping or unauthorized access.
Some security features are inherent to radio operation, such as the use of
spread-spectrum transmission; other techniques are built into the radio

4 MDS entraNET System Guide MDS 05-4055A01, Rev. C

firmware, including data encryption, enabling or 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,
every day. Section 1.4 contains additional information about entraNET
security features.

License-Free
Operation

The transceivers are designed for frequency-hopping spread-spectrum
operation in the license-free 900 MHz or 2400 MHz band. They can pro­vide reliable long distance communications over line-of-sight signal
paths.

Multiple Services Networks can include a mixture of equipment requiring Ethernet and

serial data interfaces on the same cell or AP. This flexibility allows the
transceiver to provide services in data networks that are on a migration
path from legacy serial or EIA-232-based hardware to faster and more
easily interfaced Ethernet systems.

Flexible
Management

Configuration, troubleshooting and other management activities are per­formed using a connected PC, locally or remotely. Modes of access
include a local RS-232 console, local or remote IP access through
Ethernet, Telnet, or a Web browser, and Simple Network Management
Protocol (SNMP).

Feature Summary The MDS entraNET design makes installation and configuration an

easy task, while allowing for configuration changes in the future.

• Long-range transmission over favorable, unobstructed terrain, with
sufficient antenna heights

• Low power consumption—Sleep and Shutdown modes to enable
solar-powered operation

• Repeater configurations—A repeater scheme can be established to
extend the transmission range or to work around obstructions in a
network. This is accomplished by connecting two radios back to
back at a single site.

• Industrial-grade product—Extended temperature range for trou­ble-free operation in extreme environments

• Robust radio communications—Designed to perform in high-inter­ference environments

• MDS Security Suite—Blocks common attack schemes and prevents
“rogue” hardware from gaining access to or control of a network.
Common attack events are logged and reported via alarms.

• Fast, 106 kbps data speed—Ten times faster than 9.6 kbps radios

• Simple setup—Ethernet bridge configuration option requires mini­mal setup

• Serial ports—Gateway for serial interface equipment to IP or Ether­net networks with an embedded terminal server

1.3 APPLICATIONS

The following sections describe typical entraNET installations. All
installations should be reviewed by a network manager to ensure proper
integration with existing equipment.

1.3.1 Long-Range Wireless LAN

The wireless LAN is a common application of the entraNET system. It
consists of a central control station (AP) and one or more associated
Remote radios, as shown in Figure 1-2 on Page 7. A LAN provides
communications between a central LAN/WAN and remote Ethernet
endpoints. Remote radios can support one Ethernet endpoint each.

The operation of the radio system is transparent to the computer equip­ment connected to it. As such, the system behaves just as it would in a
hardwired arrangement, with respect to data format and integrity.
Over-the-air messages are exchanged at the Ethernet level, including all
types of IP traffic.

Antenna Placement

The AP antenna is positioned at a location from which it can reliably
communicate with all of the Remote radios in the system. Commonly,
this is a relatively high location on top of a building, communications
tower or other elevated point.

Communication Rules

•A Remote transceiver can only talk over-the-air to an AP.

• Peer-to-peer communications between Remotes can take place indi-

• An AP can only talk over-the-air to Remote radios; however, two

6 MDS entraNET System Guide MDS 05-4055A01, Rev. C

rectly through the AP.

APs can communicate with each other through their Ethernet con­nectors when a wired LAN/WAN is utilized.

1.3.2 Combining Serial and Ethernet Devices

Prior to the introduction of the entraNET series, multiple networks were
often needed to service different types of communication protocols. An
entraNET system provides this functionality through a single AP radio.
Each of the Remote radios in a system can be connected via IP to dif­ferent SCADA or telemetry 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.

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,

MDS 05-4055A01, Rev. C MDS entraNET System Guide 7

including reduced management requirements when using
MDS NETview Management System (MS) software. In addition,
entraNET offers nearly unlimited potential for future applications that
run over IP and Ethernet services.

In an IP-to-serial scenario, every Remote is sent information received by
the AP Ethernet port. Likewise, information received at the Remote
serial port is transmitted to the AP, and the AP delivers this information
through its Ethernet port in the form of an IP packet.

Additionally, the AP serial port can be used as a virtual Remote. This
means that encapsulated serial information received by the AP is sent
out the serial port of all Remotes as well as the AP serial port. The
reverse is also true, meaning that data received by the serial port of any
Remote or the AP serial port is encapsulated and sent out the AP
Ethernet port.

This arrangement can be used to connect an endpoint device at a
Repeater site without the need for an additional Remote radio.

1.3.3 DNP3 Protocol-Aware Networks

The MDS implementation of Distributed Network Protocol 3 (DNP3)
allows the transfer and routing of DNP3 messages between serial
devices, while also supporting the conversion to an IP Ethernet network.
As DNP3 messages are routed through the system, the APs “learn” the
locations of all end devices, regardless of whether they are configured
for serial or Ethernet communication, eliminating the need to configure
their individual locations.

DNP3 devices with an Ethernet or IP interface can be connected to a
transceiver in one of two ways:

• To the Ethernet port of an AP radio

• To the Ethernet port of a Remote radio

DNP3 devices with a serial RS-232 interface can be connected to a
transceiver in one of two ways:

• To the serial port of an AP radio

• To the serial port of a Remote radio

The capability for DNP3 message routing is optional for the transceiver.
An Authorization Key is required to enable this functionality, and is
available for purchase from MDS.

NOTE: Detailed information on the DNP3 protocol is available on the

DNP Users’ Group Web site at www.dnp.org.

1.3.4 Upgrading an 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 employing MDS entraNET wireless equipment, including
flexible serial and Ethernet interfaces, higher data throughput, and ease
of installation.

MDS entraNET radios are well suited to replace leased lines, dial-up
lines, or existing data radios by taking advantage of the built-in serial
and Ethernet interfaces on the transceiver. The sections below discuss
two common scenarios.

Replacing Legacy Wireless Products

In most cases, legacy radio transceivers supporting serial interface
equipment can be replaced with MDS entraNET radios with little or no
special configuration. This equipment can be connected to MDS
entraNET radios through the
cable wired for EIA-232 signaling. The
EIA-232 signaling and acts as a data communications equipment (DCE)
device.

COM1 or COM2 port with a DB-25 to RJ-45

COM2 port supports standard

NOTE: Several previous MDS-brand products contained signal lines

on their interface connectors that are not used or required on
entraNET radios. Consult the equipment manual(s) for inter­face pinout information, and connect only the required pins.

Supplementing a Legacy Wireless Network with IP Services

MDS entraNET Remotes support most polled protocols. The serial
interfaces encapsulate serial data in two different modes: connectionless
(User Datagram Protocol, or UDP) and connection-oriented (Transmis-
sion Control Protocol, or TCP).

For complete details on serial gateway interface modes, see “CONFIG-

URING THE SERIAL INTERFACES” on Page 54.

1.3.5 P22 Protected Network (Redundant)
Configuration

For mission-critical applications, MDS offers the Protected Network
Station. This radio incorporates two entraNET AP transceivers, two
power supplies, and a switchover logic board that automatically selects
between Transceiver A and Transceiver B as the active radio. Figure 1-4
shows a view of the protected chassis. For system-level information on
this product, see MDS publication 05-4161A01.

2.1 INTRODUCTION

Prior to installation in the field, it is recommended that you set up the
radio system in an office or lab and become familiar with its operation
and features. This also allows tests of various network designs and con­figurations prior to arrival at a field site. A tabletop test can be per­formed with any number of radios.

This section describes the hardware setup and software configuration
needed for testing an Ethernet connection. To simulate data traffic flow
over the radio network, a PC or LAN is connected to the
AP and used to PING (P
the Remote transceiver.

NOTE: It is important to use a radio system network address and

device IP address that are different from any radios currently
in use in your region or network. This greatly reduces the
possibility of disruption to traffic on existing systems during
testing.

A recommended technique for minimizing the chance of radio
network address conflicts is to use the last four digits of the AP
serial number.

2.3 TEST SETUP

The following steps explain how to make connections to the transceiver
system, power it up, and set basic configuration. After these steps are
complete, the system is ready for field installation.

STEP 1—CONNECT THE ANTENNA PORTS

Figure 2-3 is a drawing of a tabletop arrangement. Connect the antenna

ports of each transceiver as shown through attenuators and an RF power
divider. This provides for stable communications between each radio,
while preventing interference to nearby electronic equipment.

Figure 2-3. Typical Setup for Tabletop Radio Testing

NOTE: It is very important to use attenuation between radios in the test

setup. The amount of attenuation required depends on the
number of radios being tested and the desired signal strength
(Received Signal Strength Indicator, or RSSI) at each trans­ceiver during the test. In no case should a signal greater than
–30 dBm be applied to any transceiver in the test setup. A
transmit RF power output level of +20 dBm (100 mW) is
recommended. This can be set via the radio menu (Main Menu >

Radio Configuration > RF Output Power Setpoint).

STEP 2—MEASURE AND CONNECT DC POWER

The power applied to transceivers (AP and Remotes) must be within
6–30 Vdc and be capable of continuously providing a minimum of 11
Watts. (Typical power consumption is 800 mA at 13.8 Vdc for the AP
and 600 mA at 13.8 Vdc for Remotes.)

A power connector with screw terminals is provided with each radio.
Strip the wire leads to 6 mm (0.25"). Be sure to observe proper polarity,
as shown in Figure 2-4, with the positive lead (+) on the left.

NOTE: It takes about 30 seconds for the AP transceiver to power up

and be ready for operation. The Remote requires approxi­mately five seconds to power up.

The transceiver must be used only with nega­tive-ground systems. Make sure the polarity of the
power source is correct. The radio is protected from
reverse polarity by an internal diode and an on-board
fuse.

Power Supply
Connections at 28
Vdc

Common 28 Vdc supplies are often high-current power supplies
designed primarily to charge battery banks. The radio can be operated
from these supplies, providing there are no transients on the leads as
power is applied to the radio. Transients can be created that rise above
30 Vdc to a voltage that exceeds the primary voltage rating of the radio
and can destroy its voltage regulators and other components. It is impor­tant to keep this potential hazard in mind when designing 28 Vdc power
supply connections for the radio.

• Use a two-conductor cable to power to the radio. Then the cur­rents in the positive and negative wires are equal and opposite,
causing their magnetic fields to cancel. The result is no net
inductance in the connection to cause voltage overshoot.

• Do not connect a radio to a power supply that is already pow­ered up, unless necessary (that is, when connecting a radio to a
battery bank and charger). When power is applied by switching
on a power supply, the rise time of the supply is too slow to
cause overshoot.

• Typically, there are multiple return paths for the negative side
of the power supply, through the coaxial cable shield and the
chassis, for example. Any imbalance in the currents in the
power cable results in voltage overshoot, so this should be min­imized during initial power-up if the supply cannot be turned
off.

• Add a 1 to 2

Ω, 2 Watt resistor in series with the positive lead.

This greatly limits voltage overshoot. Since these radios draw
very little current in receive mode, and transmit only briefly,
there is little loss in power efficiency. In transmit, the voltage
drop is minimal and has no effect.

• Minimize the length of the power cabling, within reason.

• When power is applied from a power source having a relatively
high (1 or 2

Ω) source impedance, or from a power source with-

out a large amount of output capacitance, no overshoot occurs.
Therefore, use a power supply that is rated appropriately for the
radio if possible—avoid using power supplies that far exceed
the radio's current requirements.

STEP 3—CONFIGURE THE AP

The instructions below summarize essential AP settings for tabletop
testing. For detailed AP log-in and menu navigation instructions, see

ACCESSING THE MENU SYSTEM on Page 36.

Log-in and Configuration

The AP must be configured first, as Remote transceivers depend on the
AP beacon signal to achieve a connected (linked) state. Figure 2-5
shows the basic setup for configuring an AP with a personal computer.
