Please allowsufficient passive or active ventilation to ensure the radiomodem’s heat sink to operate efficiently.Quick Start GuideMR450 Data RadioTypical Radio SetupOptimising the Antenna RX signalOnce the unit is operational, it is important to optimise theantenna tuning.In the case of a directional antenna, it will be necessary to alignthe antenna for the best received signal.This can be done by using the (0-5Vdc) output on Pin 9 of thePort to indicate signal strength (RSSI).TVIEW+ Programming Screen LED Indicators & Test OutputsRadio is PoweredIf all the LEDs are off, check if power is reaching the radiomodem. Successful power-up is indicated by the “PWR”LED indicating a continuous (healthy) GREEN state.Received Signal IndicatorThe “Rx/Synch” LED is used to indicate the state of thereceiver. If the LED is off, no signal is being received. ARED indication shows that an RF carrier is being received,but no data stream can be decoded. This may indicate thepresence of interference or another user on the channel.A continuous GREEN indication shows that the modem islocked and synchronised to the incoming signal, and has goodBit Error Rate (BER).Analog RSSI Output Characteristics - M Series Data Radio00.511.522.533.544.55-120 -110 -100 -90 -80 -70 -60 -50 -40Received RF Level (dBm)User Port RSSl (DC Volts)T +613 9775 0505F +613 9775 0606E support@trio.com.auwww.trio.com.auwww.trio.com.auwww.trio.com.auwww.trio.com.auwww.trio.com.auTRIO DATRIO DATRIO DATRIO DATRIO DATTTTTACOM GROUPACOM GROUPACOM GROUPACOM GROUPACOM GROUP41 Aster AvenueCarrum Downs VIC Australia 3201Information subject to change without notice.© Copyright 2004 Trio DataCom Pty Ltd.

Data into the radio modem is shown as a RED flash,and received data out of the modem is shown as a GREENflash.If data is alternately flowing in and out quickly, then theindicator appears orange.Issue : 08-04bThis voltage can be converted to dBm using the chart below.Note that this LED turns RED when the transmitter is active.
Quick Start Guide - MR450 Data Radio Section 2 Quick Start Guide - MR450 Data Radio Section 3Communications PortsThe TVIEW+ M Series User & Configuration / DiagnosticsCable is a DB9 (Male) to two DB9 (Females) patch cable. Itprovides a connection for user data and configuration /diagnostics. It is intended for RS232 serial communications.User InterfaceThe user port is wired as a RS232 DCE, configured for nohandshaking (3-wire) interface.Only 3 wires need to be connected between the radio and theapplication device. See the User Manual for further cableconfigurations.MR450 Connections LayoutTypical pins used:• Pin 2 (RxD) - Data Output from Modem.• Pin 3 (TxD) - Data Input To Modem .• Pin 5 (SG) - signal ground.Connecting Antennas and RF FeedersThe RF antenna system should be installed in accordancewith the manufacturers notes.The RF connector used on the M Series radios is an NType female connector. Always use good quality low lossfeeder cable, selected according to the length of the cablerun. Ensure all external connections are waterproofed usingamalgamating tape.Preset directional antennas in the required direction using acompass, GPS, or visual alignment and ensure correctpolarisation (vertical or horizontal). The RSSI Output (Pin 9)can be used to assist with antenna alignment (see section4).Activating the TransmitterIn most systems, the transmitter by default is controlledautomatically by the radio when it has data to transmit.To manually activate the radio transmitter, connect (ie: link)the RTS signal (Pin 7) to Aux (Pin 8).To operate in this mode, the radio must be configured viathe programming software for PTT from RTS.Caution: Ensure a RF load is present BEFOREtransmitting.Power Supply RequirementsThe M Series radio modem is designed and calibrated tooperate from a filtered 13.8Vdc regulated supply, but willoperate from a 10-16Vdc range. See the User Manual for moredetails on power supply requirements.Caution: There is NO internal replaceable fuse andtherefore an external fuse MUST be fitted as shownin diagram below (MR450: 3 amp slo-blow fuse,EB450: 5 amp fast-blow fuse, EH450 Controller 1amp slo-blow fuse).The radio is designed to self protect, and will blow the externalfuse if the voltage exceeds 16Vdc, or if reverse polarity isapplied.The radio modem can also be damaged if there is any potentialdifference between the chassis-ground, RS232 signal ground,power (-) input, or antenna coaxial shield. Before connectingany wiring, ensure all components are earthed to a commonground point (please pay particular attention to 24V PLC powersystems where converters are used).Connect the antenna and RS 232 plugs BEFORE applyingpower to the unit.Lastly, before inserting the power plug, please re-check thatthe polarity and voltage on the power plug is correct using amultimeter. Failure to use an external fuse will result in damageto the radio which will void the warranty.TVIEW+ Management Suite - RadioConfigurationThis TVIEW+ Management Suite provides a facility for localradio configuration and diagnostics.Example: Configuration session –1 Attach the TVIEW+MSeries cable between the radioData Port A and the PC serial port. Ensure theConfiguration/Diagnostics plug is connected to the PCserial port and NOT the User Data plug.2 Launch TVIEW+ & Select “Programmer”3 Select “Read” the radio4 Change the configuration as required5 Select “Write” the parameters back to the radioRefer to to the User Manual for detailed operation of advancedfeatures.Warning - RF Exposure (FCC/IC)The radio equipment described in this user manual emits lowlevel radio frequency energy. Professional installation isrequired. The concentrated energy may pose a health hazarddepending on the type of antenna used.This device is intended for FIXED installation conditions. DONOT allow people to come within 2 metres (6.6 feet) of non-directional antennas and 6 metres (20 feet) from the front ofdirectional antennas when the transmitter is operating.More information is available from www.fcc.gov/oet/info/documents/bulletins
