Quick Start Guide

Trio MR450 Gen II Data Radio

1.0 Introduction

Welcome to the Quick Start Guide for the TrioTM M-Series Data Radio. This guide provides step-by-step instructions, with simple explanations to get you up-and-running. For further information, along with information on analog mode M-Series, refer to the M-Series user manual.

Typical Radio Setup

Omni-Directional	Lightning
or Yagi Antenna	Arrestor

AC Power

External

Fuse

Power Supply (Mains to 13.8 Vdc)

Laptop/PC running TVIEW+TM Diagnostics connected to system port via TVIEW+ configuration cable

RS232 Serial Device (RTU/PLC) connected to Data Port

2.0 Mounting Guidelines

The radio should be mounted in a clean and dry location, protected from water, excessive dust, corrosive fumes, extremes of temperature and direct sunlight. In high power or high temperature applications, allow sufficient passive or active ventilation. To help minimize moisture ingress it is suggested to mount the radio with the connectors facing downwards.

Din rail mounting kits are available (part no: TBUMDIN-KIT-TYPEA). For more information, refer to the user manual.

3.0 Physical Dimensions

Choose an enclosure that is suitable for the size of the radio.

The MR450 dimensions are: 154 mm x 102 mm x 29 mm (6.1 in. x 4.1 in. x 1.2 in.)

The radio is rated for use in ambient (operating) environments from -30...+60 °C (-22...+140 °F).

4.0 Connecting Antennas and RF Feeder Cables

Section 1

Install the RF antenna system in accordance with the manufacturer’s instructions. Consider antenna gain when setting transmit power. Refer to compliance information at the end of this document and in the user manual for more information.

The RF connector on this product is an N-type female. Use good quality, low loss feeder cable, selected according to the length of the cable run. Waterproof all external connections.

5.0 Power Supply Requirements

Typical receive/standby input power is 2.5 Watts. The input power will vary in transmit mode according to RF output power level. The MR450 is supplied with a lock-in mating DC power connector (Phoenix Contact Part Number 1777989) which should be installed with the locking screws done up tightly: 0.5...0.6 Nm (4.42...5.31 lbf-in ).

Rated Operating Voltage: 10...16 Vdc	Tx Power	Typical Input
Nominal Operating Voltage: 13.8 Vdc	(dBm)	Power (W)
Input Power (Rx typical): 2.5 W	30	8.5
Input Power (Tx typical): (See table)	37	21

The radio is designed to self protect from permanent damage if the voltage exceeds 16 Vdc or if reverse polarity is applied. The radio may need to be returned for service if this occurs.

Before connecting any wiring, ensure all components are earthed to a common ground point. Connect and secure the Antenna and Serial connectors BEFORE applying power to the unit.

Lastly, before inserting the power connector, re-check that the polarity and voltage are correct using a multimeter and check the power cable against the +/- label printed on the front panel of the radio.

Failure to use an external fuse can result in damage to the radio which will void the warranty. A 3 A fast-blow fuse is recommended as an external fuse.

NOTICE

HAZARD OF EQUIPMENT DAMAGE

•The radio modem can 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.

•The radio modem can be damaged if an external fuse is not used

Failure to follow these instructions can result in equipment damage.

6.0 Communications Ports

The M-Series utilizes a single DE9 interface to provide a system port (used for configuration and diagnostics) along with an user port (used to connect to end application devices - RTU/PLC).

The shared single DE9 interface can be split by using the Serial/System Port Adaptor. This adaptor is provided with each digital mode M-Series. The adaptor is a DB9 (Male) to DB9 (Female) and RJ45 socket. This provides a connection for user data (User Data port) and configuration/diagnostics (System Port).

For details on pin-out of TVIEW+ configuration cable, refer to the ER450 Quick Start Guide.

(Part number: TBUMPROG-TVIEW)

M-Series Adapter System Port Pin-Out

(Part number: TBUMCAB-SER-ADP-A)

Typical user port pins used:

•Pin 2 (RxD) - Data Output from Modem

•Pin 3 (TxD) - Data Input To Modem

•Pin 5 (SG) - Signal Ground

7.0 LED Indicators

Radio is Powered

If all 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.

This LED will turn RED when the transmitter is active.

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.

8.0 Activating the Transmitter

A continuous GREEN indication shows that the modem is locked and synchronized to the incoming signal, and has good Bit Error Rate (BER).

Data Flow “breakout” LEDs

There is also an LED to indicate data flow into and out of the user port. Data received by the radio modem through the user port (for RF transmission) is shown as a RED flash, and data sent out of the modem through the user port (from RF reception) is shown as a GREEN flash. If data is alternately flowing in and out quickly, then the indicator appears orange.

In most systems, the transmitter, by default, is controlled automatically by the radio when it has data to transmit. To manually activate the radio transmitter, connect (i.e: link) the RTS signal (Pin 7) to Aux (Pin 8).

To operate in this mode, the radio must be configured via the programming software for PTT from RTS.

WARNING

HAZARD OF RADIO FREQUENCY (RF) BURNS

Ensure that a matching load or antenna is attached to the RF port prior to applying power to the device.

Failure to follow these instructions can result in death or serious injury.

9.0 Antenna Azimuth Alignment for Rx Signal

When using a directional antenna, azimuth alignment may be required, to achieve optimum received signal. Receiver signal strength can be read from TVIEW+ Diagnostics, which can provide the RSSI value after a poll/response, or, by measuring the DC voltage between pin 9 (RSSI) and pin 5 (GND) of the serial COM port which can output a live, RSSI to analog DC voltage, where 2.8 Vdc represents approx. -90 dBm. Indicated signal strength is equal to ~20 dB/volt, or the conversion chart shown below can be used. As the RSSI to analog DC voltage output indicates ‘live’ receiver signal strength, the radio must be listening to a permanently active transmitter, otherwise, only low levels of background noise will be indicated. (see 8.0 for instructions on activating the transmitter).
