Mounting and Environmental
Considerations
The MR450 radio comes complete with integrated mounting
feet 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 maximum ventilation for the
heat sink.
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 ensure the radio
modem’s heat sink to operate efficiently.

Typical Radio Setup
Optimising the Antenna 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 the
Port to indicate signal strength (RSSI).

LED Indicators & Test Outputs
Radio is Powered
If all the LEDs are off, check if power is reaching the radio
modem. Successful power-up is indicated by the “PWR”
LED indicating a continuous (healthy) GREEN state.
Received Signal Indicator
The “Rx/Synch” 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 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 good
Bit Error Rate (BER).

Data Flow “breakout” LEDs
There is also a LED to indicate data flow into and out of the
user port. Data into the radio modem is shown as a RED flash,
and received data out of the modem is shown as a GREEN
flash.
If data is alternately flowing in and out quickly, then the
indicator appears orange.
Issue : 08-04b
This voltage can be converted to dBm using the chart below.
Note that this LED turns RED when the transmitter is active.
