Getting Started
Antenna Connection
Carefully connect the antenna. The antenna must be vertically orientated.
Alternative high gain and externally mounting antenna options are available.
Warning –DO NOT operate the SMS Lite without an antenna connected.
SIM Card Installation
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”.
Unlock Holder Lift & Insert SIM Close Holder Lock Holder
Antenna must

Inputs
The SMS Lite inputs are to be connected to switches or mechanical contacts.
The default input names are: INP1, INP2, INP3, INP4, which can be renamed.
An input is active or ON when the input switch is closed and
inactive or OFF when the input switch is open.
Close the switch contact to turn “INP1” “ON”.
Warning –Only mechanical switches or mechanical closure devices should be
connected to the inputs. DO NOT connect external voltage or other electrical
source to the inputs.
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 DC low voltage, low current devices directly.
However, we recommend using interface relays as they improve future serviceability and are required
or higher voltages or currents.
The relays are internally protected by solid state snubbers for operating with inductive loads.
The default output relay names are: RLY1, RLY2, RLY3, RLY41, which can be renamed.
The output relays are normally open contacts.
Send “ON” command to close “RLY1” operating light.
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.
DC Power Supply
Connect a suitable 12-24V DC power supply to the 2.1mm socket labelled “12V DC”.
QTech recommends plug pack P/N PD5412 or power supplies PD5413 & PD5414.
Warning –DO NOT use Switch Mode Power Supplies (SMPS) with this
product. The DC power supply used for this product MUST have a grounded
negative or be a “linear” transformer-based plug pack. The reason is that the
antenna, programming port and external connections can provide exposed earth
points and the SMPS can impose an AC voltage on the DC ground, which can lead
to damage.

Basic 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 SMS Lite can have up to 4 phone numbers registered.
We recommend you follow these quick functional tests before performing advanced configuration.
This will help prove the SIM card, cellular network connection, device functionality and simplify
potential troubleshooting.
Register Phone 1 (Ph1) –Master User
Use this procedure to program the master user.
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.
SMS Lite
SMS Lite
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=.

Connect the I/O
Now the Master user is configured, connect the SMS Lite to the wired inputs and outputs.
Activate an Input
Activate (switch on) one of the mechanical switch inputs.
Phone 1 will be sent a text message each time the input turns on or off.
Acknowledge the Alarm
You must acknowledge receipt of the alarm notification.
To acknowledge an alarm:
OK <input name> (e.g. Text: OK INP1)
Operate an Output
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.
This is all that is required for the master phone number to receive notifications from the SMS Lite
inputs and control the outputs.
If this basic configuration was successful, continue to additional configuration for extra phone
numbers, renaming and advanced settings.
We highly recommend renaming the Site Name and the Input and Output names, as these names
are used in the text messages and can save confusion.

Additional Configuration
Further configuration is now possible to allow personalisation of your SMS Lite.
You can assign a site name 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.
Naming Conventions
Before renaming the site name, inputs, and outputs there are important considerations and
limitations.
Use alphanumeric characters –only use letters A to Z and numbers 1 to 9
Do NOT use spaces in the names –eg do not use “VSD RUN” or “PUMP SHED”
Do NOT use names longer than 8 characters –keep them short, 4 characters is recommended
Do NOT use punctuation marks or special characters: Do not use <: ; . , ? / @ # emojis etc
Do NOT use reserved keywords in the name. These includes ON, OFF, NAME, PHONE, SITE,
DEBOUNCE, DEFAULTS, OK, BUSY, PULSE, STATUS, BAL, STATS, INFO, INPUTS, OUTPUTS
Do NOT duplicate names, each name must be unique.
Additional Phone Numbers
Configure up to 3 additional users to allow notification and control options, using the same process
used to configure the Ph1 Master user.
1. Compose text message to the SMS Lite mobile number in the following format:
#[PIN][space]Ph2:number=0124567890[dot] (e.g. #12345 Ph2:number=022987654.)
2. A confirmation text will be sent to you acknowledging a configuration change.
Configuration 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
Name of the site where the SMS Lite is.
(8-character limit, no spaces)
INP1, INP2, INP3, INP4
These are the 4 individually
configurable inputs
Name
An identifying name for the input.
(8-character limit, no spaces)
