Introduction

This User’s Manual describes installation and setup of the Antx Messenger product.

The Messenger is a complete monitoring, alarm notification, and telemetry platform. It

supports monitoring of data values from on-board physical IO.

Features

The hardware feature set of this platform includes:

 Battery backed on power fail

 Power fail detection

 3 Digital Inputs (user configurable to accept a voltage or ground input)

 1 Digital Outputs (transistor closures to ground)

 1 Analog Input (10-bit, user configurable for V or ma input)

 3G or LTE cellular modem and antenna

1 Description

1.1 Capabilities

The Messenger is a highly configurable platform for remote monitoring and control

applications. Some of the capabilities are listed below.

 local computations from monitored conditions

 time stamping of monitored data and events

 battery backed historical data/event buffers

 automatic monitoring of max/min for analog values

 event and data logging

 telemetry of monitored conditions to host server-based applications via

cellular

 OTA programming and diagnostics

 SMS messages sent on monitored conditions

 parameter setting via SMS messages

 rate of change alarm/flow totalization on physical analog input channel

 pulse counter on all physical digital input channels

 high/low warning/alarm on all analog channels

 daily count and duration alarm on all physical digital input channels

1.2 Monitoring

All monitored values can be transmitted via cellular to a host server of the customer’s

choosing. Monitored values are transmitted based on time or notification events.

Notification events are based on rules set by the user and each event can generate an

immediate report. Telemetry includes cellular data connectivity to host server or SMS

messaging direct to user.

Monitored data values are mapped to fixed channels in the Messenger. A channel

defines a set of attributes for the monitored data for doing calculations, alarm detection,

data formatting, and reporting.

For example, the physical analog input is fixed to channel 62. For channel 62, the user

can set high/low limits to generate notifications to a host server or directly to the user

via SMS.

Table 4.1 provides a description of all the pre-defined channel numbers.

1.3 Host Server Communications

The Messenger utilizes a proprietary protocol to send notifications and to receive OTA

commands from a host server. Each notification typically consists of location,

date/time, an event code, and associated data. An event code provides a unique

identifier to indicate the reason that a notification is being sent – e.g. normal scheduled

update or an alarm detection event. A description of the protocol, format of messages,

and definition of event codes is available on request. Reference protocol document

“M09-PRTCLxxx”.

Some of the conditions on which notifications can be sent to the host server are listed

below:

 Any monitored value exceeding a pre-defined or user-defined limit

 A digital input changing state (on/off)

 A digital output changing state

 An analog input transitioning into a warning or alarm region

 A scheduled update

 System faults

 SMS text commands from a user or host server

 Power on or reset

1.3.1 Event Codes

Every message sent by the Messenger to a host-based server application is triggered by

an event. The event generates a message and the message contains an Event Code. The

Event Code uniquely identifies to the server the reason the message is being sent. Some

of the messages generated contain data, others serve as just notification that an event

has occurred.

1.3.2 Positive Acknowledgement

The Messenger can be configured to require a message acknowledgement from the host

server or to send once and forget. Message acknowledgement provides a verifiable

mechanism that a message was delivered, even during poor network conditions.

This parameter setting can be found in the CELL configuration.

1.3.3 Store and Forward Data Queue

There are several scenarios where a message may not be deliverable – network down,

host server down, poor connectivity to name a few. In the event that a message cannot

be delivered, it is stored in memory and is continually re-sent until properly

acknowledged. This store and forward memory is non-volatile and remains intact

during power off.

1.3.4 Real-Time Clock (RTC)

The RTC is used to time stamp data records and events. All messages sent to the host

server contain a time stamp to provide a chronology of data/events to the end user. The

RTC is battery backed to provide time keeping during power off. If the RTC is

configured to be automatically set, the Messenger will set time after every power on

and perform a time check every midnight.

The RTC can be set in one of the following ways:

Method

Description

Automatic

via Cell

This is the default setting. The

Messenger will set the RTC from an

internet NIST time server

Manually Set the time via the Debug port

through the Maintenance menu.

OTA/SMS Set from an OTA config command or

an SMS config command.

Some parameters in the OPTIONS and CELL configurations are used to define how the

RTC is set.

2 Installation and Setup

This section provides information on installing the Messenger and confirming its initial

operation.

It is recommended to read the entire chapter before starting the installation.

2.1 Installation Steps

Installation consists of the following steps:

1. Unpack the Equipment.

2. Mount the Equipment.

The Messenger should be mounted in a vertical position to try and minimize

the chance of water entering through the antenna connection. The antenna wire

should have a service loop just below the antenna connector.

3. Connect Main Power.

4. Connect field signals (digital, analog, Modbus) to the appropriate wire.

2.2 Unpacking the Equipment

The Messenger is shipped with the following:

 The Messenger electronics in a Deutsch thermoplastic enclosure or a board

only product

 A Cellular antenna (magnetic mount or bulkhead)

 User’s Guide

 Optionally, a cable harness

2.3 Mounting the Equipment

The Messenger is available in an automotive grade weather resistant enclosure.

NOTE: Mount the Messenger vertically and provide a service loop for the antenna

cable to prevent water intrusion.

2.3.1 EEC Thermoplastic Enclosure

Figure 1: Deutsch EEC Thermoplastic Enclosure Dimensions

2.4 Mounting the Antenna

The antenna shipped with the Messenger is a cellular hockey puck style. The antenna

can be ordered with a magnetic or a screw mount base.

In general, the antenna should be mounted with an unobstructed view of the sky. If the

antenna is mounted outside and may be subject to lightning, a surge arrestor can be

inserted between the antenna and the Messenger. If the antenna is mounted inside, it

should be located near a window.

NOTE: Service loops should be provided for the antenna cabling, near the antenna

connection to minimize water ingress through the connection.

2.5 DIP Switch/Jumper Settings

The Messenger uses on-board DIP switches and jumpers to configure application

specific IO and set operational modes. DIP switches 3, 4, 5, and jumper J21 are used to

select application specific IO. DIP Switch 2 is used to set operational modes. See

Figure 3 for DIP switch locations. See Figure 4 for DIP switch IO selection settings.

2.6 Cellular Setup

The Messenger supports two cellular technologies, HSPA (3G) and LTE. Both of these

radio options require a wireless account with a cellular provider such as AT&T, T-

Mobile, Sprint, Verizon, Vodafone, etc.
