2.1 Typical Radio Setup
2.0 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.

3.0 Connecting Antennas and RF
Feeders
The RF antenna system should be installed in
accordance with the manufacturers notes.
The RF connector used on the ER450 radio is an N Type
female connector. 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).
4.0 Communications Ports
4.1 System Port - RJ45
The System Port is a multi-function interface used for:
•Programming / Configuration of the radio
•Remote Diagnostics connections
To access these functions use the standard ER450
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).

4.2 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.
4.3 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.
Refer to User Manual for further details of other cable
configurations.

4.4 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.

Quick Start Guide - ER450 Data Radio 5
5.0 Power Supply and Protection
(fusing)
The ER450 radio modem is designed and calibrated to
operate from a 13.8Vdc regulated supply, but will operate
from 10-16 volts (filtered) DC.
The current requirement is typically 120mA in receive
mode, and will vary in transmit mode according to RF
output power level (typically 0.5-1.5 amps).
Caution: There is NO internal replaceable fuse, and
therefore the radio modem MUST be externally fused
with the fuse holder provided (a 3 amp slo-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 DC power plug is
correct using a multimeter.
6.0 TVIEW+ Management Suite -
Radio Configuration
This TVIEW+ Management Suite allows a number of
features including: Configuration (Local - serial, or
Remote - over-the-air), Remote DiagnosticsFacilities and
Firmware Upgrades.
The configuration wizard can be used to provide Quick
Start generic templates for the types of systems
architecture you wish to employ.
Example: Local configuration session -
1 Attach the programming cable from the PC to the
System Port of the radio (see fig 6 & 7 )
2 Launch TVIEW & Select “Programmer”
3 Select “Read” the radio
4 Change the configuration as required
5 Select “Write” the parameters back to the radio
Refer to User Manual for detailed operation of advanced
features.

7.0 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
(see fig 11) of Port B to indicate signal strength (RSSI).
This voltage can be converted to dBm using the chart
below.
8.0 LED Indicators & Test outputs
8.1 Radio is Powered
If all the LEDs are off, no power is reaching the radio
modem.
Successful power-up is indicated by the “PWR” LED
indicating a continuous (healthy) GREEN state. Note that
this LED is turned RED when the transmitter is active.
8.2 Voltage Error
If the voltage is too high(>16Vdc) or too low(<10Vdc), an
error message will be displayed as a sequence of all
LEDs flashing RED, followed by the green power LED,
repeating about three times per second.
8.3 Hardware Error
A hardware error is indicated by a slower sequence of all
LEDs flashing RED, followed by one or more of the other
LEDs flashing green, the cycle repeating about once per
second. In the case of a hardware error, the unit must be
returned to the service point for repair. In this case please
consult the User Manual for further information on the
error indicated, and record the result with the service
return information.

9.0 Verifying Operational Health
It is possible to verify the operation of the radio modem
using the indicators provided by the unit. The state of the
transmitter and receiver, and data flow can be interpreted
by the indicator LEDs (see below).
8.4 Received Signal Indicator
The “RX/SYNC” LED is used to indicate the state of the
receiver.
If the LED is off, no signal is being received.
A RED indication shows that an RF carrier is being
received, but no data stream can be decoded. This will
briefly happen at the very start of every valid received
transmission or may indicate the presence of
interference, or another user on the channel.
A continuous GREEN indication shows that the modem is
locked and synchronised to the incoming signal, and has
excellent Bit Error Rate (BER). Any losses of
synchronisation (BER errors) are shown as a visible RED
flicker of the LED.
Note: This may only be apparent on a PTMP slave when
only receiving.
8.5 Data Flow “breakout” LEDs
There are also two LEDs to indicate data flow into and
out of the two user ports.
Input data to be transmitted is shown as a RED flash, and
received data to be output to the port is shown as a
GREEN flash.
If data is alternately flowing in and out quickly, then the
indicator appears orange.
