Part B  E Series Overview

Definition of E Series Data Radio

The E Series is a range of wireless modems designed for the

transmission of data communications for SCADA, telemetry, and

any other information and control applications that utilise ASCII

messaging techniques. The E Series uses advanced “digital”

modulation and signal processing techniques to achieve

exceptionally high data throughput efficiency using traditional

licensed narrow band radio channels.

The products are available in many frequency band and regulatory

formats to suit spectrum bandplans in various continental regions.

The range is designed for both fixed point to point (PTP), and

multiple address (MAS) or point to multipoint (PMP) systems.

E Series Product Range

The E Series range consists of the basic half duplex “Remote”

radio modem, an extended feature full duplex Remote radio

modem, and ruggedised Base Station variants, including an

optional Hot Standby controller to control two base station units in

a redundant configuration.

Frequency band variants are indicated by the band prefix and

model numbering. (See Model Number Codes)

E Series Data Radio – User Manual

Part C  Applications

Generic Connectivity

The E Series has been designed for SCADA and telemetry

applications, and any other applications that use an ASCII

communications protocol, and which connect physically using the

RS232 interface standard (although converters can be used to

adapt other interfaces such as RS422/485, RS530/V35, G703 etc).

Any protocol that can be displayed using a PC based terminal

program operating via a serial comm port is suitable for

transmission by the E Series radio modems.

An ASCII protocol is any that consists of message strings formed

from ASCII characters, that being defined as a 10 or 11 bit block

including start and stop bits, 7 or 8 data bits and optional parity

bit(s). Port set-up dialog that includes the expressions “N,8,1”, or

E,7,2” or similar indicate an ASCII protocol.

Most of the dominant telemetry industry suppliers utilise proprietary

ASCII protocols, and also common “open standard” industry

protocols such as DNP3, MODBUS, TCP/IP, and PPP. These are

all ASCII. based protocols.

Industries and Applications

The E Series products are widely used in point-to-point and point-

to-multipoint (multiple access) applications for remote

interconnection of PLC’s, RTU’s, dataloggers, and other data

monitoring and control devices including specialist utility devices

(such as powerline ACR’s). In addition, other applications such as

area wide security and alarm systems, public information systems

(traffic flow and public signage systems) and environmental

monitoring systems.

Application Detail

SCADA Systems

This is where one or more centralised control sites are used to

monitor and control remote field devices over wide areas.

Examples include regional utilities monitoring and controlling

networks over entire shires or a greater city metropolis’. Industry

sectors include energy utilities (gas and electricity distribution),

water and sewerage utilities, and catchment and environment

groups (rivers, dams, and catchment management authorities).

Telemetry Systems

Dedicated telemetry control systems interconnecting sequential

devices where cabling is not practical or distances are

considerable.

Examples include ore conveyor or slurry pipeline systems, simple

water systems (pump and reservoir interlinking), broadcast industry

(linking studio to transmitter) etc.

Information Systems

Public Information systems such as freeway vehicle flow and travel

time monitoring, and feedback signage, parking signage systems,

meteorological stations etc.

Page 9

E Series Data Radio – User Manual

Part C  Applications

Systems Architecture

Point-to-Point

This simple system architecture provides a virtual connection

between the two points, similar to a cable. Dependant of the

hardware chosen, it is possible to provide a full duplex connection

(i.e. data transfer in both directions simultaneously) if required.

Point-to-Multipoint Systems

In a multiple access radio system, messages can be broadcast

from one (master) site to all others, using a half duplex radio

system, or from any site to all others, using a simplex radio

channel.

Half duplex systems often utilise a full duplex master, to make the

system simpler, and to operate faster.

In either case, it will be necessary for the application to support an

addressing system, since the master needs to be able to select

which remote device it wishes to communicate to. Normally, the

radio system is allowed to operate “transparently”, allowing the

application’s protocol to provide the addressing, and thus control

the traffic. Where the application layer does not provide the

addressing, the E Series can provide it using SID codes™. (See

Part F - Operational Features)

Page 10

E Series Data Radio – User Manual

Part C  Applications

Digipeater Systems

This configuration is used where all sites are required to

communicate via a repeater site. A repeater site is used because it

has a position and/or height advantage and thus provides superior

or extended RF coverage. The radio modem at the repeater does

not have to be physically connected to the application’s master

site. Information from the application’s master is transmitted to the

repeater via radio, and the repeater then relays this information to

the other field sites. In this scenario, the repeater is the master

from an RF point of view, and the application master is effectively a

“remote” from an RF point of view, even though it is controlling the

data transfer on the system.

Store and Forward Systems

Store and forward is used as a way of extending RF coverage by

repeating data messages from one site to another.

This can be done globally using the inbuilt data repeating functions, or

selectively using intelligent address based routing features available in

some PLC/RTU protocols.

In this case it is necessary for all units on the system to operate in

half duplex mode (only key-up when transmitting data), so that

each site is free to hear received signals from more than one

source.

Page 11

E Series Data Radio – User Manual

Part D  System Planning and Design

Understanding RF Path

Requirements

A radio modem needs a minimum amount of received RF signal to

operate reliably and provide adequate data throughput.

In most cases, spectrum regulatory authorities will also define or

limit the amount of signal that can be transmitted, and the

transmitted power will decay with distance and other factors, as it

moves away from the transmitting antenna.

It follows, therefore, that for a given transmission level, there will be

a finite distance at which a receiver can operate reliably with

respect to the transmitter.

Apart from signal loss due to distance, other factors that will decay

a signal include obstructions (hills, buildings, foliage), horizon

(effectively the bulge between two points on the earth), and (to a

minimal extent at UHF frequencies) factors such as fog, heavy

rain-bursts, dust storms, etc.

In order to ascertain the available RF coverage from a transmitting

station, it will be necessary to consider these factors. This can be

done in a number of ways, including

(a) using basic formulas to calculate the theoretically

available signal - allowing only for free space loss due to

distance,

(b) using sophisticated software to build earth terrain models

and apply other correction factors such as earth curvature

and the effects of obstructions, and

It is good design practice to consider the results of at least two of

these models to design a radio path.

Antenna Gain

By compressing the transmission energy into a disc or beam, the

antenna provides more energy (a stronger signal) in that direction,

and thus is said to have a performance “gain” over a basic omni

antenna. Gain is usually expressed in dBd, which is referenced to

a standard folded dipole. Gain can also be expressed in dBi, which

is referenced to a theoretical “isotropic” radiator. Either way, if you

intend to send and receive signals from a single direction, there is

advantage in using a directional antenna - both due to the

increased signal in the wanted direction, and the relatively

decreased signal in the unwanted direction (i.e. “interference

rejection” properties).

Tuning the Antenna

Many antennas are manufactured for use over a wide frequency

range. Typical fixed use antennas such as folded dipoles and yagis

are generally supplied with the quoted gain available over the

entire specified band range, and do not require tuning. Co-linear

antennas are normally built to a specific frequency specified when

ordering.

With mobile “whip” type antennas, it is sometimes necessary to

“tune” the antenna for the best performance on the required

frequency. This is usually done by trimming an antenna element

whilst measuring VSWR, or simply trimming to a manufacturer

supplied chart showing length vs frequency. These antennas would

normally be supplied with the tuning information provided.

Antenna Placement

When mounting the antenna, it is necessary to consider the

following criteria:

The mounting structure will need to be solid enough to withstand

additional loading on the antenna mount due to extreme wind, ice

or snow (and in some cases large birds).

For omni directional antennas, it is necessary to consider the effect

of the mounting structure (tower mast or building) on the radiation

pattern. Close in structures, particularly steel structures, can alter

the radiation pattern of the antenna. Where possible, omni

antennas should always be mounted on the top of the mast or pole

to minimise this effect. If this is not possible, mount the antenna on

a horizontal outrigger to get it at least 1-2m away from the

structure. When mounting on buildings, a small mast or pole (2-4m)

can significantly improve the radiation pattern by providing

clearance from the building structure.

For directional antennas, it is generally only necessary to consider

the structure in relation to the forward radiation pattern of the

antenna, unless the structure is metallic, and of a solid nature. In

this case it is also prudent to position the antenna as far away from

the structure as is practical. With directional antennas, it is also

necessary to ensure that the antenna cannot move in such a way

that the directional beamwidth will be affected. For long yagi

antennas, it is often necessary to instal a fibreglass strut to

stablilise the antenna under windy conditions.

Alignment of Directional Antennas

This is generally performed by altering the alignment of the

antenna whilst measuring the received signal strength. If the signal

is weak, it may be necessary to pre-align the antenna using a

compass, GPS, or visual or map guidance in order to “find” the

wanted signal. Yagi antennas have a number of lower gain “lobes”

centred around the primary lobe. When aligning for best signal

strength, it is important to scan the antenna through at least 90

degrees, to ensure that the centre (strongest) lobe is identified.

When aligning a directional antenna, avoid placing your hands or

body in the vicinity of the radiating element or the forward beam

pattern, as this will affect the performance of the antenna.

Selecting Antennas

There are basically two types of antennas – omni directional, and

directional.

Omni directional antennas are designed to radiate signal in a 360

degrees segment around the antenna. Basic short range antennas

such as folded dipoles and ground independent whips are used to

radiate the signal in a “ball” shaped pattern. High gain omni

antennas such as the “co-linear” compress the sphere of energy

into the horizontal plane, providing a relatively flat “disc” shaped

pattern which goes further because all of the energy is radiated in

the horizontal plane.

Directional antennas are designed to concentrate the signal into

“beam” of energy for transmission in a single direction (ie for point-

to-point or remote to base applications).

Beamwidths vary according to the antenna type, and so can be

selected to suit design requirements. The most common UHF

directional antenna is the yagi, which offers useable beam widths

of 30-50 degrees. Even higher “gain” is available using parabolic

“dish” type antennas such as gridpacks.

Data Connectivity

The V24 Standard

The E Series radio modems provide two asynchronous V24

compliant RS232 ports for connection to serial data devices.

There are two types of RS232 interfaces – DTE and DCE.

DTE stands for data terminal equipment and is generally applied to

any intelligent device that has a need to communicate to another

device via RS232. For example: P.C. Comm ports are always DTE,

as are most PLC and RTU serial ports.

DCE stands for data communication equipment and is generally

applied to a device used for sending data over some medium

(wires, radio, fibre etc), i.e. any MODEM.

The standard interface between a DTE and DCE device (using the

same connector type) is a straight through cable (ie each pin

connects to the same numbered corresponding pin at the other end

of the cable).

The “V24” definition originally specified the DB25 connector

standard, but this has been complicated by the emergence of the

DB9 (pseudo) standard for asynch devices, and this connector

standard has different pin assignments.

The wiring standard is “unbalanced”, and provides for three basic

data transfer wires (TXD, RXD, and SG – signal ground).

Hardware Handshaking

Hardware handshake lines are also employed to provide flow

control, however (in the telemetry industry) many devices do not

always support all (or any) flow control lines.

For this reason, the E Series modems can be configured for full

hardware flow control, or no flow control at all (simple 3 wire

interface).

Note: that when connecting devices together with differing

handshake implementations, it is sometimes necessary to “loop”

handshake pins in order to fool the devices handshaking

requirements.

In telemetry applications (particularly where port speeds can be set

to the same rate as the radio systems over-air rate) then flow

control, and therefore handshaking, is usually NOT required. It

follows that any devices that CAN be configured for “no flow

control” should be used in this mode to simplify cabling

requirements.

Handshaking lines can generally be looped as follows:

DTE (terminal) – loop RTS to CTS, and DTR to DSR and DCE.

DCE (modem) - loop DSR to DTR and RTS (note-not required for

E Series modem when set for no handshaking).

RF Feeders and Protection

The antenna is connected to the radio modem by way of an RF

feeder. In choosing the feeder type, one must compromise

between the loss caused by the feeder, and the cost, flexibility, and

bulk of lower loss feeders. To do this, it is often prudent to perform

path analysis first, in order to determine how much “spare” signal

can be allowed to be lost in the feeder. The feeder is also a critical

part of the lightning protection system.

All elevated antennas may be exposed to induced or direct

lightning strikes, and correct grounding of the feeder and mast are

an essential part of this process. Gas discharge lightning arresters

should also be fitted to any site that stands elevated or alone,

particularly in rural areas.

Power Supply and Environmental

Considerations

General

When mounting the equipment, consideration should be given to

the environmental aspects of the site. The cabinet should be

positioned so that it is shaded from hot afternoon sun, or icy cold

wind. Whilst the radios are designed for harsh temperature

extremes, they will give a longer service life if operated in a more

stable temperature environment. In an industrial environment, the

radio modems should be isolated from excessive vibration, which

can destroy electronic components, joints, and crystals.

The cabinet should provide full protection from moisture, dust,

corrosive atmospheres, and other aspects such as ants and small

vermin (who’s residues can be corrosive or conductive). The radio

modem will radiate heat from the in-built heatsink, and the higher

the transmitter duty cycle, the more heat will be radiated from the

heatsink. Ensure there is sufficient ventilation in the form of

passive or forced air circulation to ensure that the radio is able to

maintain quoted temperature limits.

Power Supply

The power supply should provide a clean, filtered DC source. The

radio modem is designed and calibrated to operate from a

13.8VDC regulated supply, but will operate from 10-15 volts

(filtered) DC.

The power supply must be able to supply sufficient current to

provide clean filtered DC under the full current conditions of the

radio modem (ie when transmitting full RF power). The current

requirement is typically 120mA (230mA for EB450) in receive

mode, and will vary in transmit mode according to RF output power

level (typically 0.5-1.5 amps, 1.3-2.5 amps for EB450).

Solar Applications

In solar or battery-backed installations, a battery management unit

should be fitted to cut off power to the radio when battery levels fall

below the minimum voltage specification of the radio. In solar

applications, a solar regulation unit MUST ALSO be fitted to ensure

that the radio (and battery) is protected from excessive voltage

under full sun conditions.

When calculating solar and battery capacity requirements, the

constant current consumption will be approximately equal to the

transmit current multiplied by the duty cycle of the transmitter, plus

the receive current multiplied by the (remaining) duty cycle of the

receiver.

The Tx/Rx duty cycle will be entirely dependent on the amount of

data being transmitted by the radio modem, unless the device has

been configured for continuous transmit, in which case the

constant current consumption will be equal to the transmit current

only (at 100% duty cycle).

Site Earthing

The radio must not be allowed to provide a ground path from

chassis to (DB9) signal ground or (-) battery ground. Ensure that

the chassis mounting plate, power supply (-) earth, RTU terminal

device, and lightning arrester (if fitted), are all securely earthed to a

common ground point to which an earth stake is attached. Please

pay particular attention to 24VDC PLC systems using DC-DC

converters to supply 13.8Vdc.

Caution: There is NO internal replaceable fuse, and

therefore the radio modem MUST be externally fused with

the fuse holder provided (ER450: 3 amp slo-blow fuse,

EB450: 5 amp fast-blow fuse).

Mounting and Environmental

Considerations

The ER450 radio comes complete with a mounting cradle and is

attached to a panel or tray by means of screws or bolts, using the hole

slots provided.

Note: In high power or high temperature applications, it is desirable to

mount the radio with the heatsink uppermost to allow ventalation for

the heatsink.

The radio should be mounted in a clean and dry location, protected

from water, excessive dust, corrosive fumes, extremes of

temperature and direct sunlight. Please allow sufficient passive or

active ventilation to allow the radio modem’s heatsink to operate

efficiently.

ER450 Connections Layout

Connecting Antennas and RF Feeders

The RF antenna system should be installed in accordance with the

manufacturers notes.

The RF connector used on the E Series radios are N Type female

connectors. Always use good quality low loss feeder cable,

selected according to the length of the cable run. Ensure all

external connections are waterproofed using amalgamating tape.

Preset directional antennas in the required direction using a

compass, GPS, or visual alignment and ensure correct polarisation

(vertical or horizontal).

Communications Ports

System Port  RJ45

The System Port (available front and rear on EB/EH450) is a multi-

function interface used for:

• Programming / Configuration of the radio

• Remote Diagnostics connections

To access these functions use the standard E Series System Cable

assembly (RJ45 Cable and RJ45 to DB9 Adaptor).

System Port pinout assignments:

Pin 1 System port data out (RS232)

Pin 2 System port data in (RS232)

Pin 3 Not used

Pin 4 Shutdown

Pin 5 Not used

Pin 6 Not used

Pin 7 Ground

Pin 8 External PTT

Special user pinouts:

• Shutdown (Pin 4) - Active low for power save function

• External PTT (Pin 8) - Provides a manual PTT override

facility for enabling the transmitter. For testing this can be

activated by connecting PTT (Pin 8 ) to Gnd (Pin 7).

User Interfaces  Ports A & B

Each user port (A & B) is wired as a RS232 DCE, configurable for no

handshaking (3-wire) interface, or for hardware or software (X-on/X-off)

flow control. In most systems flow control is not required, in which

case only 3 wires need to be connected between the radio and the

application device.

Typical pins used:

• Pin 2 (RxD) - data output from the radio modem,

• Pin 3 (TxD) - data input to the radio modem,

• Pin 5 (SG) - signal ground.

See Part D – System Planning and Design - Data Connectivity, for

further details of other cable configurations.

RS232 Connector Pin outs (DCE)

Port A and B, Female DB9

Activating the Transmitter

In most systems, the transmitter by default is controlled

automatically by the radio when it has data to transmit.

In some systems, such as full duplex point-to-point links or full

duplex point-to-multipoint base stations, it is desirable to run the

transmitter all the time (hot keyed).

Two mechanisms are provided to do this:

• the radio modem can be configured to transmit continuously

whenever powered, or

• the radio modem can be configured to transmit whenever an

external RTS signal (Pin 7) is applied to one (or either) user

ports. (To simulate an external RTS input, loop pins 6 to 7).

To operate in these modes, the radio must be configured via the

programming software.

Caution: When the radio is configured to transmit

continuously, ensure an RF load is present BEFORE

applying power to the unit.

Page 25

E Series Data Radio – User Manual

Part E  Getting Started- ER450

Power Supply Requirements

The E Series radio modem is designed and calibrated to operate from

a filtered 13.8Vdc regulated supply, but will operate from a 10-16Vdc

(11-16Vdc for EB450 & EH450) range.

The current requirement is typically 120mA (230mA for EB450) in

receive mode, and will vary in transmit mode according to RF

output power level (typically: ER450 0.5-1.5 amps, EB450 1.3-2.5

amps, EH450 2-3.2 amps).

Caution: There is NO internal replaceable fuse, and therefore

the radio modem MUST be externally fused with the fuse

holder provided (ER450: 3 amp slo-blow fuse, EB450: 5

amp fast-blow fuse).

The radio is designed to self protect, and will blow the external

fuse if the voltage exceeds 16Vdc, or if reverse polarity is applied.

The radio modem can also be damaged if there is any potential

difference between the chassis-ground, RS232 signal ground,

power (-) input, or antenna coaxial shield. Before connecting any

wiring, ensure all components are earthed to a common ground

point (please pay particular attention to 24V PLC power systems

where converters are used).

Connect the antenna and RS 232 plugs BEFORE applying power

to the unit.

Lastly, before inserting the power plug, please re-check that the

polarity and voltage on the power plug is correct using a

multimeter.

Optimising the Antenna for VSWR and

best RX signal

Once the unit is operational, it is important to optimise the antenna

tuning.

In the case of a directional antenna, it will be necessary to align the

antenna for the best received signal.

This can be done by using the (0-5Vdc) output on Pin 9 of Port B to

indicate signal strength (RSSI). This voltage can be converted to

dBm using the chart below.

VSWR testing is achieved by activating the radio’s transmitter

using:

a) An RTS loop

b) A system port PTT plug

See Part G - Commissioning for further details.

LED Indicators & Test Outputs

Introduction

Welcome to the Quick Start Guide for the EB450 Base / Repeater

Data Radio. This guide provides step-by-step instructions, with

simple explanations to get you up-and-running.

Mounting and Environmental

Considerations

The EB450 Base Station is housed in a 2RU 19” rack enclosure.

The 4 mounting holes on the front panel should be used to secure

the unit to the rack.

The radio should be mounted in a clean and dry location, protected

from water, excessive dust, corrosive fumes, extremes of

temperature and direct sunlight. Please allow sufficient passive or

active ventilation to allow the radio modem’s heatsink to operate

efficiently.

All permanent connections are made at the rear of the unit. This

includes: Power, Antenna, Communications Ports, Digital I/O and

System Port. The front panel has an additional System Port

connection point for easy access.

Full Duplex Considerations

The EB450 is designed for continuous full duplex transmission. An

automatic thermostatically controlled fan will operate whenever the

internal temperature exceeds 50 degrees Celsius.

External Duplexer Considerations

The EB450 is normally supplied with seperate Tx and Rx ports for

connection to an external duplexing system.

Depending on the frequency band of operation and the Tx/Rx

frequency split, internal band reject duplexers are available.

EH450 Quick Start Guide

Introduction

Welcome to the Quick Start Guide for the EH450 Hot Standby Base /

Repeater Station. This section provides additional step-by-step

instructions to install, commission and operate the EH450 Hot

Standby Base Station. This document should be read in conjunction

with the EB450 Base Station Quick Start Guide.

The EH450 is a fully redundant, hot standby digital data radio base /

repeater station providing automatic changeover facilities.

The EH450 is designed as a modular solution, comprising 2 identical

EB450 base station units (standard) linked to a central, fail-safe

monitoring and change-over controller (Hot Standby Controller). Either

base station may be taken out for maintenance without the need for

any system down time. The automatic change-over is triggered by out

of tolerance (alarm) conditions based on either RF and/or user data

throughput paramaters.

Operational Description

The Hot Standby Controller (HSC) unit is a 1RU rack mounted

module that interfaces to two physically separate base stations (each

2RU rack mounted modules) via a number of RF and data cables.

Both base stations are operating simultaneously and both units are

constantly receiving signals, however only data from one base

station, the “online” base station is directed to the user equipment. The

online base station is the only base station transmitting at any time.

The Hot Standby Controller has the following functions:

• Diplex the transmit and receive paths (Assuming internal

duplexer fitted), TX Only.

• Amplify and split the incoming signal two ways so both base

stations receive at once.

• Monitor status reports from both base stations to identify faults

and swap over the online base station if required.

• Switch the antenna via internal coaxial relay duplexer to the

online base station transmitter and inhibit the offline base station

from transmitting.

• Switch the User A and B data ports through to the online base

station.

An optocoupler based switch in the base station controller directs data

to and from ports A and B on the rear panel directly to ports A and B on

the on-line base station without any involvement from the Hot Standby

controller microcontrollers (apart from selecting the on-line base). This

provides protection of the system from failure of the microcontroller.

As well as ports A and B, each base has a system port. The system

port of each base station is interfaced to the microcontroller on the Hot

Standby controller. This allows the microcontroller in charge of

selecting the base station to receive diagnostic messages from each

base station to decide their health.

The base station has it’s own system port on the rear panel and this is

interfaced to the Hot Standby Contruller Module. The HSC will route

diagnostics at the rear panel system port to and from the system ports

of the base stations.

Mounting and Environmental

Considerations

The EH450 Hot Standby Base Station is housed as a 5RU 19” rack

mounted set, encompassing 2 x 2RU Base Station units and 1 x 1RU

Hot Standby Controller unit. The mounting holes on the front panels

should be used to secure the units to the rack.

The unit should be mounted in a clean and dry location, protected from

water, excessive dust, corrosive fumes, extremes of temperature and

direct sunlight. Please allow sufficient passive or active ventilation to

allow the radio modem’s heatsink to operate efficiently.

All permanent connections are made at the rear of the unit. This

includes: Power, Antenna, Communications Ports, Digital I/O and

System Port. The front panel has an additional System Port

connection point for easy access.

The Base Station front panel system ports must not be used while in

this config.

Communications Ports

The A & B Data Ports and System Ports of each Base Station

connect directly to the Hot Standby Controller units corresponding

ports with the cables provided. Ensure all clamping screws on the

Data Port cables are firmly secured and the System Port cables are

clipped in correctly. See figure below for further details.

Note: Only the front or rear User System Port can be used at any

one time on the HSC.

Power Supply and Protection

The EH450 has facilities for dual power supplies to provide for a

redundant system. A separate power supply should be used for each

of the Base Station units. The Hot Standby Controller unit has

connections for dual power supplies and it is recommended that the

power supplies from each of the Base Stations also be used to power

the Hot Standby Controller unit. See Figure below for further details.

See ER450 Quick Start Guide Section for detailed wiring information.

The Hot Standby Controller units A & B Data Ports connect directly to

you application device and the System Port connects directly to your

local PC. See ER450 Quick Start Guide Section for further details.

Front Panel Operation

Switches

Select Switch

The 3 position switch (1 / Auto / 2) on the front panel provides the

following functionality:

• Position 1: base station 1 is forced into operation

• Position Auto: changeover hardware will select the online base

station

• Position 2: base station 2 is forced into operation

The select switch is also used to identify the target base station for

configuration programming.

Adjacent to the select switch are two LEDs: These LEDs indicate the

current active base station.

Select LED’s

•Green - Auto Mode

•Red - Remote Force

•Amber - Local Force

Reset Switch

This is a momentary close switch which when depressed will reset all

LED alarm indications.

System Port

There are two system port connection points, one on the rear panel

and one on the front panel. Both have the same functionality and can

be used for local diagnostics, firmware front panel downloads and hot

standby controller testing. To access the system port use the

diagnostic/programming cable supplied.

Note: Wnen connection is made to front panel system rear system

port is disabled.

Alarm Status LEDs

There are 10 alarm LEDs on the fron panel, five for base 1 and five for

base 2. These LEDs provide a general indication of base station

status. More detailed base station status information is available by

using the diagnostic utility software.

The indicated alarms for each base station are:

Freq. => Frequency Error

RxSig => Receive Signal (RF) Error

Data => Receive Data Error

TxPower => Transmit Power (RF) Error

Supply => DC Voltage Error

The status of each alarm is represented as follows:

Green => No Error

Red => Current (active) Error condition

Amber => Recovered Error condition

Any active or recovered error LEDs will turn to green after the reset

alarms switch has been pushed or remotely reset.
