About This User Guide
This document aids with the installation and operation of the QTech SMS Lite system. Included in this
document is:
•How to install the SMS Lite module
•SMS Lite operation
•Device Configuration
•Device Specifications
Contact QTech for application notes, which can be obtained to provide guidance for specific
configuration scenarios, detailing the configuration workflow steps.
Product Overview
The SMS Lite is a cellular remote-control device that uses text messages to provide up to four people
with status conditions, notifications, and control options for its four switched inputs and two relay
outputs. It is operational within minutes with the minimum configuration requirement being the
registering of a single cellular number to the SMS Lite. No external software is required.
The SMS Lite supports connection to current New Zealand telecommunications companies
(Spark/Vodafone/2Degrees) and selected Australian Networks including Telstra and Optus but not all
frequency band classes. Contact QTech for advice on supported networks if necessary.
Each SMS Lite is supplied with the following:
-Qty 1x SMS Lite Module (P/N PD8640-4G)
-Qty 1x Antenna (stub type), 2dBi gain (P/N PD9230)
The power supply is not included - please order a plug pack P/N PD5412 if required or visit our website
for suitable alternatives.
Features
•4 digital inputs
•2 digital outputs
•Solar power charging and battery operation (when supplied with QTech RSS01 Remote Solar
Station enclosure).
•3G Bands (MHz) B1(2100), B5(850), B8(900)
•4G Bands (MHz) B1(2100), B3(1800), B5(850), B8(900) B28(700)
•Configuration by text messaging, no programming software required
Please read this guide before using the SMS Lite.
Please ensure you read the technical details prior to connecting ANY external device to the
SMS Lite.
This version of the SMS Lite is configured for NZ and AU cellular networks only.
(For use in other countries, please contact QTech)

Getting Started
Antenna Connection
Carefully connect the antenna. Do not operate the SMS Lite without an antenna connected. The
antenna must be vertically orientated.
Alternative high gain and externally mounting antenna options are available.
Install the SIM Card
Before installing the SIM card, ensure that it is registered and activated on the Telco’s network.
We recommend you insert the SIM into a regular cell phone and check that you can send and receive
messages. Carefully remove the SMS Lite cover by prising the side panels close to the retaining
dimples.
Locate the SIM card holder adjacent to the antenna. Push the top of the holder in the direction of the
“Open” arrows to “Unlock” (toward antenna), then flip open (away from the antenna).
Carefully insert the SIM card from your chosen Telco. Be careful to orientate the card correctly, once
in place carefully slide the plastic retainer towards the antenna to “Lock”.

Inputs and Outputs (I/O)
The basic I/O connection details are shown in the diagram below.
Default Setting <input name>: INP1 INP2 INP3 INP4
These can be labelled –refer to Configuration Instructions.
Close switch contact to turn “INP1” “ON” Send “ON” command to close “RLY1”

Output Relays
The output relays are normally open devices with a maximum rating of 32V DC at a current of 2A. The
relays can switch low DC voltage, low current devices directly. However, we recommend using
interface relays as they improve future serviceability and are required for higher voltages or currents.
Warning –DO NOT directly connect to 220V AC voltage. The New Zealand and Australian wiring regulations require
that any wiring in excess of 32 volts must be carried out or be certified by a registered electrician. Consult your local
electrical installer for further guidance.

Configuration
To operate the SMS Lite, the device must have a mobile number registered as ‘Phone 1’ referred to as
Ph1. You must register this number before you can configure any of the inputs or outputs.
The device can have up to 4 phone numbers registered. It is recommended that Ph1 is the main
contact as any alarm escalations programmed will step in numerical order Ph1, Ph2, Ph3, and Ph4.
If there is no response, the next number in the list is sent a notification after 10 minutes or if a busy
message is received from the previous phone the next person is also notified.
Register Phone 1 (Ph1) –Master User
Use the following procedure to program up to 4 individual phone numbers.
1. Locate the PIN (Personal Identification Number) printed inside your SMS Lite case.
The PIN in this example is 12345.
2. Compose text message to the SMS Lite mobile number in the following format:
#[PIN][space]Ph1:number=0123456789[dot] (e.g. #12345 Ph1:number=027987654.)
3. A confirmation text will be sent to you acknowledging a configuration change.

You have changed the
configuration of the SMS
Lite. Send “INPUTS”,
“OUTPUTS”, or
“PHONES” to view the
configuration.
#12345 ph1:number=027987654.
Each configuration command must be finished with a full stop (.)
The PIN is used each time a configuration change is made
A setting can be overridden by sending a new configuration message. A configured input, output, or phone number
can also be cleared by sending a configuration message with a blank value:
#[PIN][space]Ph2:number=.

Using the SMS Lite 4G
You can now connect the SMS Lite to the required inputs and outputs and configure them.
Inputs
Once the SMS Lite is configured, Phone 1 will be sent a message each time any of the inputs turn on
or off. They must acknowledge receipt of the notification. Up to 3 other phones can be programmed
to receive a notification. If Phone 1 replies ‘busy’ or if there is no response after 10 minutes, the SMS
Lite will send a text to the next programmed number.
Outputs
Once the SMS Lite is configured, Phone 1 can control the outputs by sending the following
commands:
-Turn the specified output on
ON <output name> (e.g. ON RLY1)
-Turn the specified output off
OFF <output name> (e.g. OFF RLY1)
-To pulse an output on for one second then off again
PULSE <output name> (e.g. PULSE RLY1)
-To pulse an output for a defined period of time
PULSE <output name> <duration> <units> (e.g. PULSE RLY1 10 mins)
Where the units can be ms, sec, min, or hr, and the maximum duration is 1 day.
To allow control permissions to more than one phone, each output will need to be configured.
This is all that is required for your configured phone number to receive notifications from the SMS
Lite Inputs and control the outputs. While it is not strictly necessary, we highly recommend
programming the Site Name and the Input and Output names, especially where you have multiple
connections as these names are used in the text messages and can save confusion.
If you do not rename the inputs and outputs, they will operate under their default names which are:
<input name> INP1 → INP4 and <output name>: RLY1 & RLY2
A configuration worksheet can be found at the back of this manual and on our website. We highly recommend you
use these to record the Site, I/O names and the phone numbers and their escalation order.

Configuration Overview
Further configuration is possible to allow personalisation of your SMS Lite. You can assign a site
name to the SMS Lite, as well as naming each of the inputs and outputs, and assigning phone(s) to
these. The SMS Lite can be configured with up to 4 phone numbers allowing multiple user
notifications and control options.
All configuration text messages sent to the SMS Lite must in the form of:
#[PIN][space]<object>:<item>=<value>[dot]
e.g. #12345 Site:Name=Shed1.
Or
#12345 INP1:Name=Pump.
Configuration options are shown in the following table:
Object
Item
Value
Site
Name
The name of the site where
the SMS Lite is installed. (8-
character limit)

These are the 4 individually
configurable inputs

Configuration messages can be sent individually with one text message per configuration instruction
or in a combined text message:
Tip –DO NOT use a space in the naming convention for the Site Name, Inputs or Outputs i.e. “Back Gate”should
read “BackGate”. Or “High Lvl”should read “HighLvl”. Remember to keep the names less than 8 characters long.
