Chapter One INTRODUCTION

1.1 General

The 455U-D radio modem provides reliable radio modem operation with advanced

communication control and diagnostics functions. Radio modems transmit serial data over a

long distance via radio. The serial data is not changed - the output data is the same as the

input data. Although the 455U-D is intended to be simple in its application, it also provides

many sophisticated features. This manual should be read carefully to ensure that the modules

are configured and installed to give reliable performance.

Each 455U-D module will connect to a host device by RS232 or RS485 serial connection.

Examples of host devices are PLC’s, data loggers, intelligent transducers and computers. The

455U-D unit can receive data from the host device and transmit this data by radio to another

(or several) 455U-D module. The other module will recreate the serial data and output it as

either a RS232 or RS485 serial signal. The 455U-D unit provides two-way communications -

each module can accept serial data and also output serial data.

The 455U-D module has two data ports (one RS232 and one RS485) and can connect to two

host devices independently. The 455U-D also has another RS232 port (via a RJ45 connector)

which can be used only for configuration or access to diagnostics information - the RS232

data port can also be used for configuration and diagnostics.

RS232 is an electrical standard format for a full duplex point-to-point serial connection.

RS485 is an electrical standard format for a half-duplex multidrop serial connection. Up

to 32 devices can communicate on a common RS485 serial bus.

Each 455U-D can simultaneously

connect to signals from both RS232

and RS485. In addition, RS232 data

from one host device can be

transmitted to a remote 455U-D unit

and output as RS485 data to another

host device.

The unit includes a fixed frequency

radio transceiver with overall

frequency range 360MHz to 512MHz,

in seven radio bands, each 20MHz wide. The user can configure the radio frequency within

the 20MHz band (refer to Diagnostics section).

The 455U-D is available with a high power radio (0.5 – 5W) suitable for licensed narrow-

width channels (12.5, 20 or 25KHz). The unit is also available with a lower power radio (10

– 500mW) suitable for license-free narrow-width channels, in countries where these are

available.

The operating parameters of the 455U-D are configured from a PC using a Microsoft

Windows configuration package provided free with the module, or from a PC terminal using

Hayes commands.

1.1.1 Basic Operation

The operation of the 455U-D radio modem is relatively simple. As data is received at the

serial port, the data is transmitted on the radio channel. Up to 1020 bytes of data can be

transmitted in one transmission. The radio transmission commences when the first data byte is

received, and ends when there are no more data bytes in the input buffer, or when the number

of bytes transmitted equals the maximum message length (user configurable - default 1020

bytes). If more than 1020 bytes is input, the 455U-D unit will transmit the first 1020 bytes,

then the next 1020 bytes, and so on until all of the data has been transmitted.

Because the radio data rate could be less than the input serial data rate, an input memory

buffer of up to 8Kbytes is provided. The RS232 connection provides CTS control to prevent

the buffer overflowing. There are no data flow control signals for RS485.

1.1.2 Operating Modes

A radio channel cannot provide as secure a data channel as a wired connection. The 455U-D

uses a radio band with a low level of natural or industrial noise, however there is a chance of

interference from other users on the radio channel. We recommend that the flow of data over

the radio channel is controlled by using error detection and “handshaking” - that is, returning

an acknowledgment transmission if a data packet is received on the radio channel without

error. This function can be performed by either the host devices or the 455U-D modules.

The modules may be configured by the user to operate in one of two modes. In

Unacknowledged mode, it is assumed that the host devices control the flow of data - the

455U-D does not provide handshaking. In Acknowledged mode, the 455U-D units provide

handshaking to control the flow of data.

The RS485 port always operates in Unacknowledged mode.

455U-D Radio Modem Module User Manual

Page 10 © Sep 2008

1.1.3 Repeater Functionality

A 455U-D unit can act as a repeater for other units. A repeater receives a radio message from

one unit and re-transmits it on to another unit.

Up to seven repeater addresses can be configured in a radio link.

If transmitting to the wildcard 0 address in Unacknowledged mode (that is, a broadcast

transmission), then the repeater unit can be configured to also output the data to its own host

device.

1.1.4 Hot Redundant Standby

Two 455U-D units can be installed together in a Dual Redundant relationship - an active unit

with a hot redundant standby. One unit is configured as a “primary” unit and the other the

“secondary”. The secondary unit acts as a standby for the primary.

Under normal operation, the primary unit is active and the standby is inactive. If the internal

diagnostics in the primary detects a fault or an operating problem, the primary stops normal

operation and the secondary becomes active. The inactive unit is powered and operational,

however communications out of the unit via the radio transmitter and RS485 port is disabled.

Both units have the same configuration apart from primary/secondary selection.

1.2 Unacknowledged Mode

The default configuration of the 455U-D modem is unacknowledged mode - the modules are

set in this mode at the factory.

In unacknowledged mode,

units do not provide

handshaking functions to

control the flow of data.

Messages are not

acknowledged, and are sent

on a “Best attempt” basis.

It is up to the host

equipment to determine if

data is lost or corrupted.

To improve reliability in this mode, units may be configured to send each message multiple

times (configured in S-Register S29). The receiving unit will detect repeat messages and only

send the data out the serial port once.

Each modem is configured with a separate unit address. In Unacknowledged mode, messages

may be sent

•to a particular modem by using the remote unit’s address, or

UNACKNOWLEDGED MODE

UNIT

DATA

DATA NO

DATA

Chapter One Introduction

Man_455U-D Rev 3.03 Page 11

•to all modems in the system, as a broadcast message by using the wildcard address 0. The

wildcard address is

used to send a message

to a group of modems.

Data received at the serial

port is transmitted out of

the radio port, addressed to

the configured destination

455U-D module, or to all

modules by using address

0. Data received from the

radio with the correct

addressing is transmitted

out of one of the serial

ports (RS232 or RS485).

Prior to transmitting, units will listen to the radio channel to ensure that it is clear - units will

hold off from transmitting until the radio channel is clear.

At the RS232 port, the CTS pin can be configured to go high while there is space in the input

data buffer - otherwise it is always high.

Host devices should provide a suitable protocol to ensure that error checking, handshaking and

implementation of an appropriate re-transmission scheme is provided. This mode of operation

is particularly suited to devices designed to operate over a multidrop network, such as PLC

systems designed for operation over a RS-485 network.

If error checking is not configured at the receiving unit, data will start to be output

immediately after the first byte of data has been received. If error checking is configured, data

will be output approx 1mSec after the end of the message. For example, a message with 20

bytes of data transmitted at 19200 bits/sec will begin to be output approx 23 msec after the

data is input, if there is no error checking, or 31 msec after the data is input if error checking is

configured - this assumes the minimum lead-in time of 20 msec is configured.

1.3 Acknowledged Mode

In Acknowledged mode,

data is transferred between

the RS-232 ports of two

modules (that is, a point to

point link). One of the

modules is configured as a

“master” (or initiator) unit

and the other as a “slave”

(or responder) unit. There

can be many slave units in

the system, however the
