Below are the basic steps for installing the LEDR radio. When making cable connections, refer to page 10 for a rear panel view of the radio.
1. Install and connect the antenna system to the radio
• Ensure a path study has been conducted and that the radio path is acceptable.
• Use good quality, low loss coaxial cable. Keep the feedline as short as possible.
• Preset directional antennas in the direction of desired transmission/reception.
2. Connect the data equipment to appropriate rear panel connector
• For standard “S” Series radios, see Figure 25.
• For radios equipped with an FT1 Option Board, see Figure 26.
• Verify the data equipment is configured as DTE. (By default, the radio is configured as DCE.)
3. Apply DC power to the radio
• Verify that the voltage matches the power supply operating range (24 Vdc or 48 Vdc).
• The power connector is a three-pin keyed connector. The power source can be connected with either polarity. The center conductor is
not
connected.
4. Set the radio’s basic configuration using front panel or Console interface
• You must first login with a valid username and password (see page 16).
• Set the transmit/receive frequencies (

2.0 INSTALLATION

Installation of the LEDR transceiver is not difficult, but it does require some planning to ensure optimal efficiency and reliability. This section provides tips for selecting an appropriate site, choosing antennas and feedlines, and minimizing the chance of interference. This material should be reviewed before beginning equipment installation.

2.1 General Requirements

There are four main requirements for installing the transceiver—a suit­able installation environment, adequate and stable primary power, a good antenna system, and the correct interface between the transceiver and the external data equipment. Figure 6 shows a typical station arrangement.

Site Selection

For a successful installation, careful thought must be given to selecting proper sites for the radios and antenna systems. Suitable sites should offer:
• An antenna location that provides an unobstructed path in the direction of the associated station
• A source of adequate and stable primary power
• Suitable entrances for antenna, interface or other required cabling
• Adequate clearance around the radio for ventilation
These requirements can be quickly determined in most cases. A possible exception is the first item—verifying that an unobstructed transmission path exists. Microwave radio signals travel primarily by line-of-sight, and obstructions between the sending and receiving stations will affect system performance. This is especially important for the LEDR 1400S, which operates in the 1400 MHz microwave frequency band.
If you are not familiar with the effects of terrain and other obstructions on radio transmission, the following discussion will provide helpful background.

Terrain and Signal Strength

A line-of-sight path between stations is highly desirable, and provides the most reliable communications link in all cases. A line-of-sight path can often be achieved by mounting each station antenna on a tower or other elevated structure that raises it to a level sufficient to clear sur­rounding terrain and other obstructions.
The requirement for a clear transmission path depends upon the distance to be covered by the system. If the system is to cover only a limited dis­tance, say 5 km (3.1 miles), then some obstructions in the transmission path may be tolerable. For longer-range systems, any obstruction could compromise the performance of the system, or block transmission entirely.
The signal strength at the receiver must exceed the receiver sensitivity by an amount known as the fade margin to provide reliable operation under various conditions.
Detailed information on path planning should be reviewed before begin­ning an installation. See RF Propagation Planning on page 87 for more information. Computer software is also available for this purpose that can greatly simplify the steps involved in planning a path.
MDS 05-3627A01, Rev. A LEDR S Series I/O Guide 5
Adaptive Broadband/MDS offers path analysis (for paths in the USA) as an engineering service. Contact the factory for additional informa­tion.

On-the-Air Test

If you’ve analyzed the proposed transmission path and feel that it is acceptable, an on-the-air test of the equipment and path should be con­ducted. This not only verifies the path study results, but allows you to see firsthand the factors involved at each installation site.
The test can be performed by installing a radio at each end of the pro­posed link and checking the Received Signal Strength Indication (RSSI) value reported at the front panel LCD screen of each radio. If adequate signal strength cannot be obtained, it may be necessary to mount the sta­tion antennas higher, use higher gain antennas, or select a different site for one or both stations.

A Word About Interference

Interference is possible in any radio system. However, since the LEDR radio is designed for use in a licensed system, interference is less likely because frequency allocations are normally coordinated with consider­ation given to geographic location and existing operating frequencies.
C/I Curves
The risk of interference can be further reduced through prudent system design and configuration. Allow adequate separation between frequen­cies and radio systems.
A carrier to interference (C/I) curve can help in frequency and space coordination. The information in this curve can aid greatly in helping plan geographic locations and frequency usage for radio systems. Con­tact the factory for additional information on carrier to interference curves. A whitepaper on the subject is available on request. Ask for Pub­lication No. 05-3638A01.
Keep the following points in mind when setting up your point-to-point system:
1. Systems installed in lightly populated areas are least likely to encounter interference; those in urban and suburban environments are more likely to be affected by other devices operating in the radio’s frequency band and adjacent services.
2. Directional antennas must be used at each end of a point-to-point link. They confine the transmission and reception pattern to a com­paratively narrow beam, which minimizes interference to and from stations located outside the pattern. The larger the antenna, the more focused the transmission and reception pattern and the higher the gain.
6 LEDR S Series I/O Guide MDS 05-3627A01, Rev. A
3. If interference is suspected from another system, it may be helpful to use antenna polarization that is opposite to the interfering sys­tem’s antennas. An additional 20 dB (or more) of attenuation to interference can be achieved by using opposite antenna polarization. Refer to the antenna manufacturer’s instructions for details on changing polarization.

2.2 Antenna and Feedline Selection

Antennas

The antenna system is perhaps the most crucial part of the system design. An antenna system that uses poor quality feedline, or is improp­erly aligned with the companion site, will result in poor performance, or no communication at all.
A directional antenna must be used for point-to-point systems to mini­mize interference both to and from nearby systems. In general, cylin­drical or dish type antennas with a parabolic reflector must be used. Yagi or corner reflector types may be acceptable in some applications. Check government regulations.
The exact style of antenna used depends on the size and layout of a system. In most cases, a directional “dish” type of antenna is used with the radio (Figure 7). Dish antennas maximize transmission efficiency and restrict the radiation pattern to the desired transmission path.

Adaptive Broadband Corporation/MDS can also furnish antennas for use with the transceiver. Consult your sales representative for details.

Feedlines

For maximum performance, a good quality feedline must be used to connect the transceiver to the antenna. For short-range transmission, or where very short lengths of cable are used (up to 8 meters/26 feet), an inexpensive coax cable such as Type RG-213 may be acceptable.
8 LEDR S Series I/O Guide MDS 05-3627A01, Rev. A
For longer cable runs, or for longer-range communication paths, we rec­ommend using a low-loss cable suited for 1400 MHz, such as Andrew Heliax
®
. Whichever type of cable is used, it should be kept as short as
possible to minimize signal loss. Table 4, Table 5 and Table 6 list several types of acceptable feedlines
and the associated losses according to operating frequency.

2.3 Radio Mounting

The radio can be mounted either in a 19-inch equipment rack or on a table top. It should be located in a relatively clean, dust-free environ­ment that allows easy access to the rear panel connectors as well as front panel controls and indicators. Air must be allowed to pass freely over the ventilation holes and heat sink on the side panel.
MDS 05-3627A01, Rev. A LEDR S Series I/O Guide 9
The dimensions of the LEDR radio are:
• 305 mm (12 in) deep
• 426 mm (16.75 in) wide—excluding rack brackets
• 45 mm (1.75 in) high—1RU

Attaching the Rack Brackets

The radio is normally shipped with the rack brackets uninstalled. To attach them, select the desired mounting position on the sides of the chassis. (The brackets may be mounted flush with the front panel, or near the middle of the chassis.)
Both short and long screws are provided with the brackets. Use the long screws for the heatsink (left) side of the chassis and the short screws for the right side of the chassis. Tighten the screws securely.

3.0 OPERATION

The LEDR radio is designed for continuous, unattended operation. Under normal conditions, the only time operator intervention is required is to power the unit up or down, or to change an operating parameter. This section explains the use of the radio’s controls and indicators and provides steps for initial startup of the equipment.

3.1 Initial Startup

NOTE: The LEDR radio is normally keyed continuously, and the radio
will transmit whenever power is applied. Ensure there is a suit­able load on the antenna connector before connecting power.
Operation of the radio can be started by simply connecting primary power to the unit. After a short self-test, a “default screen” similar to the following appears on the radio’s LCD display:
LLLLEEEEDDDDRRRR LLLLiiiinnnnkkkk RRRRSSSSSSSSIIII:::: ----66660000 ddddBBBBmm
MDS 05-3627A01, Rev. A LEDR S Series I/O Guide 15
mm

Maximizing RSSI

For newly installed systems, one of the first tasks is to orient the station antenna for a maximum Received Signal Strength Indication (RSSI) as shown on the LCD screen. See “Performance” on page 30 for details. A maximum RSSI ensures the antenna is properly aimed at the associated station. Move the antenna slowly while an assistant observes the RSSI display for a maximum reading.
Initial Login
Required to change radio settings
When the radio is first powered up, it defaults to a read-only condition. That is, the radio parameters may be viewed, but cannot be changed. To enable changes to radio settings, a valid user name and password must be entered.
When the radio is shipped from the factory, it is pre-programmed with the following temporary login credentials:
Username: Password:
Keypad Method To log in from the front panel using the temporary credentials, follow

3. Enter the password SUPER. The following response appears: login:
SUPER logged in.
The user may now access any of the console commands listed in Table 12 on page 36 with Administrator level privileges (the highest allowable user level).
Changing the SUPER Password (Recommended)
The factory-programmed username and password (SUPER) is provided to enable a System Administrator to operate a newly installed radio. It is highly recommended that the password for
SUPER be changed as soon
as possible to maintain system security. Follow these steps to change the factory-programmed password:
1. Login as
SUPER using the Console Method described above.
(Passwords cannot be changed using the front panel keypad.)
2. Enter the command
passwd. At the next prompt, enter a new pass-
word (eight characters maximum).
3. Re-enter your new password (for verification purposes). If the entry is correct, the radio responds with
user: Command Complete.
You may now set up additional accounts, set permission levels, or delete accounts as desired using the
user command. See page 58 for complete
description of this command.
NOTE: It is recommended that users log out when finished using the
keypad or console terminal. This can be done using the Logout screen on the radio, or the logout command from a console terminal as appropriate. If there is no keypad or terminal
activity for 10 minutes, the radio automatically logs out and reverts to read-only status.

3.2 Communicating with the Radio

There are four different methods available to set radio parameters and query the radio.
Front Panel—The front panel is intended to serve as a conve-
nient user interface for local radio management. Most, but not all, parameters and functions are accessible from the front panel.
SNMP Network Management System—The SNMP agent
interface is optimized to fulfill the fault configuration, perfor­mance and user access requirements of the LEDR radio system. A separate guide, P/N 05-3532A01 explains SNMP in more detail.
• Telnet—A standard network application protocol which pro-
vides a console-type interface to configure and query most radio parameters.
• EMS (Element Management System)—The EMS is used via
a terminal connected to the front panel console port. It may be used to configure and query every manageable radio parameter on a given network using the out-of-band service channel. The EMS may be used on the local radio ( remote radio (
rlogin command).
login command) or on the
STATUS LEDS

Front Panel Controls

Figure 12 shows the LEDR radio’s front panel controls and indicators. The front panel includes LEDs, an LCD display screen and a menu nav­igation keypad.
MENU NAVIGATION BUTTONS
LCD DISPLAY
Figure 12. Front Panel Interface
ALARM STATUS LEDS
18 LEDR S Series I/O Guide MDS 05-3627A01, Rev. A
LEDs The front panel LEDs indicate the following conditions when lit:
POWER—Main Power is applied to radio. ACTIVE—This is the Primary unit in a redundant configuration. ALARM—A general alarm condition is present RX ALARM—The modem is not locked to a receive signal TX ALARM—There is a problem with the transmitter I/O ALARM—There is a payload data interface error
LCD Display/Keypad The LCD display provides a 2 line by 16 character readout of radio
status and parameter settings. It is used with the menu navigation keypad on the right side of the front panel to control the radio’s opera­tion and access diagnostic information.
Use of the keypad (Figure 13) is simple, and allows many basic oper­ating tasks to be performed without connecting an external terminal or using additional software.
Invisible place holder
Figure 13. Menu Navigation Keypad
The keypad buttons can be used for two functions; Navigation, and Editing. The functions of the keys are automatically selected according to the screen that is being viewed by the user.
Navigation Mode—This is the default mode. The left and right
keys ( ) navigate through the available top level screens (see menu tree, Figure 14). The
ENTER
key allows entry into a screen,
exposing another level of menus or entering edit mode for a radio parameter. The
ENTER
key always exits the current screen, causing
the program to “pop out” one level.
Edit Mode—In editable screens, pressing the key puts the
ENTER
screen in Edit mode. The technique for applying new data depends on the particular edit mode used by that screen. LEDR screens have four edit sub-modes; List, Character edit, Text Entry, and Horizon­tal Bar.
MDS 05-3627A01, Rev. A LEDR S Series I/O Guide 19
In List mode, the left and right keys scroll through a list of

ENTER
choices. Pressing when the desired choice is selected attempts to apply the changes. Pressing
drops out of the
edit mode without saving changes. The Character Edit mode consists a cursor move mode and a
character scroll mode. Upon entering the Character Edit mode, the left and right keys move the cursor in the corresponding direction. When the cursor is below the character to change,
pressing
ENTER
again puts the screen in character scroll mode in
which the left and right keys scroll through the available charac­ters. Pressing
ENTER
saves the new character and reverts to cursor
move mode. To save all changes made in cursor move mode, place the cursor under the special “Enter” character and press
ENTER
. Pressing in character scroll mode reverts to cursor
move mode. Pressing in cursor move mode cancels char-
ENTER
acter edit mode without saving any changes. The Text Entry mode is a slight modification to the Character
Edit mode above. Upon entering Text Entry mode the cursor is in the leftmost position and the keys scroll through the
available characters. Pressing saves the current character
ENTER
and moves the cursor to the next position to the right. When the text is correctly entered, moving the cursor to the special “Enter”
character and pressing attempts to save the new text. Pressing in cursor move mode cancels Text Entry mode
ENTER
ENTER
without saving any changes. The Horizontal Bar mode is used in some menu screens. It
allows adjustment of the LCD display for the best contrast using the keys (see Front Panel menu, page 33). The right key corresponds to upward viewing angle; the left key corresponds
to downward viewing angle. Pressing
saves the adjusted
value as the default setting. It works in a similar manner for the Orderwire menu (see page
33) to adjust the Volume and VOX threshold.

Front Panel Menu Tree

The LEDR radio contains several top level menus (see Table 8). These serve as entry points to a variety of sub menus that can be used to view or adjust operating parameters and diagnose the radio link.
