On a windows based computer you will be able to use ‘Hyperterminal’ (free with Windows). For PDA or
Pocket PC you can use several communication programs that can be downloaded from the internet like
‘ZTERM for Pocket PC’ (http://www.coolstf.com/ztermppc).

When you receive the unit, we recommend configuring the unit functions and setup using the Personal setup
configuration program. The WTGAT has many functions that will allow the unit to operate for different user
applications including security and continues tracking using SMS or GPRS.

VERY IMPORTANT:

Before you can start using the WTGAT the battery will need to be charged. The battery can be charged with
the unit powered on or off. The power on switch is located on the side off the unit.
Disconnect external battery charge or communication cable first before powering down the unit.

The build in battery charger automatic charges the battery whenever you connect to the battery ch arger.
When you power on the unit 3 leds will flash for about 1-2 seconds.

At startup the WTGAT will test memory, GPS module, GSM module and if sim card is installed.
The WTGAT cannot operate without s im car d in s t a l le d .

The 5 leds on the WTGAT have the following functions:
Yellow led

This is the GSM status led.
The LED will be OFF when there is NO GSM signal.
The LED will be ON if the GSM module OK and has GSM signal or is in sleep mode (except deep sleep
mode).
If blinking the GSM module is in test mode.

During diagnostic startup the GSM led will flash.

Green led

This is the GPS status led.
If off the GPS module is powered down.
If on then the GPS module has power, but non-valid GPS location.
If blinking the GPS module has power and valid GPS location.

Red led1

This is the Battery status led.
If off and charger is connected then battery is fully charged.
If on then battery is charging.

Blue led
This is the Park, Motion or status LED when Panic input is configured to pickup and hang up Voice call (Park
or Motion function can be configured using the configuration menu program).
If off the Park, Motion or 24H no movement detection is off.
If ON then Park, Motion or 24H no movement detection is on.

2. Getting started, use Hyper Terminal to test WTGAT

Step 1

Connect WTGAT with your PC using the USB port. You may need to install the USB driver
that is supplied with the unit. This driver will install a USB serial port on your computer.

Step 2

Using Hyper Terminal
The PC will need to be running HYPERTERMINAL, which is a free program that
comes with Windows.
If HyperTerminal is not currently installed on the PC you will need to do the
following:

1. Go to Start/Settings/Control Panel.

2. Go to Add/Remove Programs/Windows Setup Tab. This will bring up a list of

components that can be installed.

3. Put a tick in the Communications Check box and double click. This will bring up a

list of components that can be installed. Put a tick in the box next to HyperTerminal.
You may need to insert your Windows Disk to install the program.

4. You may need to restart your computer after the program has installed.

5. Remember to connect the serial port on the unit to the serial port on the PC.

Once HyperTerminal is installed and running you will need to set the Baud Rate to
9600 Baud and set the Com Port (usually Com 4 on a laptop) to the USB serial port
created.

We strongly recommend that the unit be tested using a computer as this allows all
options to be tested quickly and easily. The operating system/or a new or modified
operating system can only be uploaded (in x-modem format) if the unit is
connected to a serial port on a computer.

Step 3

Power up the unit. The Yellow, Green and Blue led will flash for 1-2 seconds.
Please make sure you have charged the battery and sim card is installed.

3. Configuration and setup :

When the tracking unit powers up it will enter the ‘Diagnostic menu’ first. If no key is pressed for 5 seconds
the unit will enter normal operating mode.
Only change the settings that you require different, leave all other settings the same.

Please note : The ‘WTGAT-setup.exe’ program can only access the
tracking unit if the unit is working in normal operating mode !!!! So
after Power ON you must wait +/- 1 minute or wait until the Yellow
(GSM status LED) is flashing.

After power up you must wait until the unit passes the Diagnostic test. In Diagnostic test mode you cannot
connect to the tracking unit and you must wait at least 1+ Minutes before connecting.
In normal running mode (after diagnostic mode) the tracking unit may also be busy in other processes and
the unit will only response to the configuration software after finishing the process.
Therefore, when upload or download configuration, it may need to wait for few minutes especially the unit
was setup for real time tracking already.
The best timing to upload the configuration is right after quit from diagnostic menu with hyper terminal."

Installing SIM card with different PIN NUMBER then 0000 or None:

The default configuration after operating system upload or when you receive the WTGAT for the first time is
NO SIM PIN number or SIM PIN number is 0000 (4 * zero). If you cannot remove SIM PIN number make
sure that your SIM PIN is configured for 0000.

The WTGAT will first test if SIM PIN number is required. If the SIM card requires PIN number then the
WTGAT will try to access the SIM card using the default pin number 0000 (4* zero).

To change the SIM PIN number you must follow the following instructions.

1. First upload the current configuration from your WTGAT and set ‘SIM PIN CODE’ to none (empty).

2. Then download the settings to your WTGAT.

3. Switch off the WTGAT and remove SIM card.

4. Use your normal mobile phone to change the SIM pin number.

5. Insert the SIM card back into the WTGAT and switch on the WTGAT.

6. Wait for about 1 minute before using the configuration menu program.

7. Upload the configuration from the WTGAT.

8. Set the PIN CODE to the new PIN code you have configured (using your mobile phone).

9. Download the configuration to the WTGAT

Send Status Message after Real
time wake up:

When the WTGAT wakes up during ‘Real time wake up’ it

will try to get valid GPS location (if enabled). Once valid

GPS location is found a status message will be send. If no

valid GPS location is found after 5 minutes then status

message with the last valid GPS location message will be

send. After message is send the WTGAT will wait 3

minutes for any messages received by SMS or GPRS.

(1) The WTGAT has 3 different working modes. What mode selected depends on
your application. To explain how the WTGAT works we use ‘Normal working mode’
and ‘Sleep mode’. In normal running mode the WTGAT can be activated by any
inputs and will process any SMS messages or incoming phone calls.

-Normal Running mode (GSM on - GPS on when motion is detected)

This mode will use most power when selected. The WTGAT will enter normal
running mode when movement or motion is detected and automatic enter sleep
mode after no movement or motion detected for more then 5 minutes. SMS
messages and incoming phone calls will automatic wake up the WTGAT to enter
normal running mode. When the WTGAT enters sleep mode only ADC input

24

- 25 -

activation cannot be detected. In sleep mode the GSM led will be on. All other leds
will be off unless battery is charging or battery is low.

-Basic Sleep mode (GSM off - GPS off - Motion/Timer/AUX1/ Panic)

In this mode the WTGAT will not receive any SMS messages, incoming phone calls
or check ADC input for activation.
The WTGAT will wake up to enter normal running mode when motion, Real time
timer time is expired, AUX1 input is activated or Panic input is activated.
The WTGAT will enter sleep mode after 5 minutes if no inputs are activated.
In ‘Basic sleep mode’ all leds will be off unless battery is charging or battery is low.

-Deep Sleep mode (GSM off - GSM off - Timer/ Panic input)

In this mode the WTGAT main power is switched off. The WTGAT will not use any
power from the main battery. The build in backup battery will supply power to the
low power timer chip. Maximum power savings can be archived to allow the WTGAT
to work for several years(*) without battery charge or battery change.
The WTGAT will enter sleep mode after 5 minutes if no inputs are activated.
Park or motion switch will not work when the WTGAT enters ‘Deep Sleep mode’.
In ‘Deep sleep mode’ all leds will be off unless battery is charging or battery is low.

In ‘Deep Sleep mode’ there are only three ways that the WTGAT will wake up.

- The Panic input is activated for more then 4 seconds.

- The low power timer time is expired.

- Wire loop connected to the Panic input is broken (cut) if connected for more
then 4 seconds.

(*) This assumes that the battery has negligible self-discharge
(2) In Sleep mode the WTGAT can wake up when minutes, hours, day or date

matches the internal time or date depending on the ‘Real time wake up settings’
selected.

The following ‘Real time wake up settings’ can be selected from the menu:

- Disabled

- When minutes match

- When hours and minutes match

- When day, hours and minutes match

- When date, hours and minutes match

- After configured minutes delay
Disabled

When selected the WTGAT will not wake up by low power timer.

When minutes match

When selected the WTGAT will wake up when minutes selected match the lo w
power minutes.

Example:
Minutes configured in the configuration menu is 22.
When the low power timer minutes is also 22 then the low power time will wake up
the WTGAT to resume operation in normal running mode.

When hours and minutes match

When selected the WTGAT will wake up when hours and minutes selected match
the low power hours and minutes.

Example:

25

- 26 -

Hours configured in the configuration menu is 8.
Minutes configured in the configuration menu is 22
When the low power timer hour is 8 and minutes is 22 then the low power time will
wake up the WTGAT to resume operation in normal running mode.

When day, hours and minutes match

When selected the WTGAT will wake up when Day, hours and minutes selected
match the low power Day, hours and minutes.

Example:
Day configured is Monday.
Hours configured in the configuration menu is 8.
Minutes configured in the configuration menu is 22
When the low power timer Day is Monday and hour is 8 and minutes is 22 then the
low power time will wake up the WTGAT to resume operation in normal running
mode.

When date, hours and minutes match

When selected the WTGAT will wake up when Date, hours and minutes selected
match the low power Date, hours and minutes.

Example:
Date configured is 19.
Hours configured in the configuration menu is 8.
Minutes configured in the configuration menu is 22
When the low power timer Date is 19 and hour is 8 and minutes is 22 then the low
power time will wake up the WTGAT to resume operation in normal running mode.

After configured minutes delay

When selected the WTGAT will wake up after the configured delay in minutes
expires.

Example:
Minutes delay configured is 20.
Just before the WTGAT enters sleep mode the minutes delay time configured is
added to the current time for the next wake up. If the current time is say 12:35:19
then 20 minutes will be added to give next wake up at 12:55:00 (seconds are NOT
added!).
The WTGAT will then resume normal running mode.

Please note that when the WTGAT is in basic sleep mode the ‘Send Location for missed
phone call’ may not respond on the first phone call (GSM modem is on). We suggest
making another phone call about 1 minute after the first call if no message is received.

(3)

If the WTGAT is configured for ‘Deep sleep mode’ then movement will only be detected if
the WTGAT wakes up if wake up interval is configured for ‘Real time wake up settings’ or if
Panic input is activated. During ‘Deep sleep mode’ no movement can be detected.

(4)
This options works as follows:
Once incoming call is received you can use the Panic input to pickup the voice call. The
Panic status (Blue LED) will be ON once the WTGAT has detected that you have pressed
the Panic input button.

26

- 27 -

Once the call is connected you can use the Panic button again to disconnect the phone
call. The Blue LED will go OFF once the WTGAT has disconnected the call.
The user has to release the Panic button after the call has been disconnected to prevent
that Panic activation is detected.

(5)

Only one function can be selected at one time for AUX2 (input/output).

4. SMS commands accepted by the tracking unit:

The unit will only process SMS commands sent to the unit. If the unit is configured in SMS and GPRS mode
then any confirm, update or location message is sent back using GPRS.
The unit can read and sent any SMS messages without disconnection from the GPRS connection.

When sending SMS commands please make sure that the message has the correct data format. Some
commands may require a fixed length. Command message must NOT contain any extra spaces, commas or
any other characters. This is very important to make sure the Rover processes the correct command
messages.

WARNING:

Default security code is ‘0123456789’ and the option is automatic disabled after operating system upload.
We strongly recommend for your network to keep secure to change the ‘Security ID code’ first and do not
leave it set to ‘0123456789’.
Base phone number 2 can receive the following End user text messages:

- Park Alert Activated

- Stop MOTION Alert Activated

- PANIC Button Activated

- Low Battery Voltage

- OVERSPEED Alert No Movement 24 Hours Alert

The configuration menu allows to choose different language for custom message to Base phone
number 2. Default language is English.

Unit activation and sleep Mode:

The tracking unit has a build in ‘motion’ sensor that detects any movement and g-force change.
The WTGAT will enter ‘sleep’ mode after 5 minutes if no ‘motion’ is detected. In sleep mode the GPS
module is powered down, but the unit will still process any incoming and outgoing SMS messages if ‘Normal’
running mode is selected.
When the unit is in ‘Normal’ and ‘Basic sleep mode’ it will take several seconds to ‘wake up’ to normal
running mode after motion is detected. Motion is normally detected when you move the unit.
A valid GPS location can take several seconds to several minutes (depending if the WTGAT had valid GPS
location before and the time when there was last valid GPS location) after the unit is operating in normal
running mode (GPS aerial has clear sky view).

Software and hardware lock-ups:

The unit has an internal har dware timer that detects ‘lock-up’.
If the unit is ‘locked’ in it automatic ‘reset’ after 5-10 minutes.

5. Uploading the Operating System to the WTGAT

The firmware file should have an extension file name “.s19”.
When the Rover module is connected to the serial port of a computer and it is in Diagnostic mode,
A new or modif ied Operating System can be uploaded to the Rover module by pressing 0.
The new or modified Operating System will be distributed in the X-Modem format. It will be a small file that is

capable of being distributed to installers by email.
Once you hav e received the new operati ng system by ema i l place it in a new folder on your computer (we

would recommend calling the folder WTGAT).

· With the WTGAT connected to the computer and in Diagnostic mode press 0 to begin the upload.

*PLEASE NOTE

Update the ‘operating system’ does not delete or change any saved GPS locations, Base phone number or
dial out phone numbers.

33

- 34 -

· On the HyperTerminal main screen click on Transfer and then Send File from the drop down list.

· Click Browse to locate the folder that contains the Operating System file. Highlight the file and click Open.

· Then click Send File. The download will begin.

34

- 35 -

After upload the WTGAT unit will restart into the Diagnostic Main Menu. The Version and Date details of
the new Operating System will be displayed.

35

- 36 -

6. Messages send by WTGAT:

Message from the WTGAT can be send using SMS or GPRS. In SMS only mode all data is sent using SMS.
In SMS and GPRS mode all messages are sent using GPRS. If SMS and GPRS mode is enabled and GPRS
is not availa ble then any inpu t activations will be sent using SMS. Whenever GPRS is available again the
unit will use GPRS again. In case real time tracking is enabled in SMS and GPRS mode and GPRS is not
available then the unit can send the data using SMS if enabled (see configuration menu).

If GSM signal is not available and input is activated then the tracking unit will send the alarm message as
soon as there is GSM signal again. The time and date in the message is from the GPS time and date at the

When configured as output this value will be $FF (255).
When configured to use external digital thermometer (DS18S20) the output value will be between $00 and
$FF (255 max).

2. Confirm Message:

A confirm message will be sent whenever the tracking unit receives a command to update
a setting.

The WTGAT has 3 Base phone numbers that can be configured to allow configuration
setup.

Information that is received from the 3 Base phone numbers is processed as
follows:

Base 1:

Master Base phone number. Accepts all command messages and update
messages. Location request or configuration update messages are sent back to Master
Base phone number if unit is configured for SMS only.
In combined working mode (SMS and GPRS) the location request or configuration update
message is sent back using GPRS.

Base 2:
The following message(s) can be displayed:

This phone number can be used by the ‘End User’ to receive a ‘Pager’ message.

PARK Alert Activated
Stop MOTION Alert Activated
PANIC Button Activated
Low Battery Voltage
OVERSPEED Alert
No Movement 24 Hours Alert

The ‘End User’ will also receive a confirm message(*) if the option is enabled or disabled
by the Base 1 or Base 3 phone number.
(*) Only if option can be enabled or disabled by SMS or GPRS command.

Park Alert is activated when the WTGAT detects a speed faster then 5km/h or 3
movements within 30 seconds. After the message is send the PARK Alert function will
automatic reactivate after 60 seconds (if Park switch is ON only!). Message sending when
activated is delayed for 20 seconds when activated when enabled using the PARK switch.

38

- 39 -

This will give the user time to switch off the PARK switch.

Base 3:

Master Backup Base phone number. Accepts all command messages and update
messages. Location request or configuration update messages are sent back to Master
Backup Base phone number only.
In combined working mode (SMS and GPRS) the location re quest or configuration update
message is also sent back to Master Backup Base phone number.
The Master Backup phone number will also receive input alarm activation messages
(Panic, Park, Power loss detected etc.) as ‘location format’ message.

Confirm message format:

05*827,CONFIRM,xx,x1,x2, ,0 <,IMEI optional if enabled>

Where xx, x1, x2 etc is the command code setting that has been updated.

The xx can have the following settings:

12,13,17,19,20,21,22,23,24,26,27,28,29,30,32,5,51,53,55,56,56,64,66,67,68,74,79,90,91,A0,A1,A

3. Message that cannot be send:

The WTGAT will automatic save location and activation messages to memory. If ‘Resend Missed
locations’ is enabled and the message cannot be send then the message(s) that where not send
will automatic be resend.
Depending on your communication mode selected (SMS Only or SMS and GPRS) the messages
are send back using SMS or GPRS.
Up to 5000+ locations can be send back.

Example:

Real time tracking is enabled and configured to send message every 60 seconds using SMS.
While moving you enter a location where there is no GSM signal. You stay at that location for 12
minutes. After that you returned to a location where there is GSM signal.

First location saved Last location saved

When the next real time tracking location (*) needs to be sent back and the transmission is
successful the WTGAT will try to send back the missed locations. Missed locations are sent back
starting from the last saved location (1). One message (SMS or GPRS) will contain 4 locations.

Example message showing 4 locations:

00012459374312125290900000003iFG8699.00012459374312125290900000003i0G8699.000124

Example as shown:
The first digit represent hour. To convert back you must use the ASCII table.

The ASCII value for ‘3’ is 51 (Hex 32). Subtract 48 to find the number = 3.
If the ASCII value is less then 90 (Hex 5A) then you must subtract 48 to get the number.
If the ASCII value is more then 90 (Hex 5A) then you must subtract 55 to get the number.

The second digit represent minutes. To convert back you must use the ASCII table.
The ASCII value for ‘i’ is 105 (Hex 69). Subtract 55 to find the number = 50.
If the ASCII value is less then 90 (Hex 5A) then you must subtract 48 to get the number.
If the ASCII value is more then 90 (Hex 5A) then you must subtract 55 to get the number.

The third digit represent seconds. To convert back y ou must use the ASCII table.
The ASCII value for ‘F’ is 70 (Hex 46). Subtract 48 to find the number = 22.
If the ASCII value is less then 90 (Hex 5A) then you must subtract 48 to get the number.
If the ASCII value is more then 90 (Hex 5A) then you must subtract 55 to get the number.

The time shown in the example is : 03:50:22

GPS date:

date is compressed to 3 digits.
It can be easy converted back.

Example as shown:
The first digit represent day. To convert back you must use the ASCII table.

The ASCII value for ‘G’ is 71 (Hex 47). Subtract 48 to find the number = 23.
If the ASCII value is less then 90 (Hex 5A) then you must subtract 48 to get the number.
If the ASCII value is more then 90 (Hex 5A) then you must subtract 55 to get the number.

The second digit represent month. To convert back you must use the ASCII table.
The ASCII value for ‘8’ is 56 (Hex 38). Subtract 48 to find the number = 8.
If the ASCII value is less then 90 (Hex 5A) then you must subtract 48 to get the number.
If the ASCII value is more then 90 (Hex 5A) then you must subtract 55 to get the number.

The missed messages for real time tracking can have 1 to 4 locations (max) in each message.
So in the above example we will receive 3 messages that have 4 locations.
If we have only 2 saved locations we will only receive 1 message that has 2 locations.

Up to 25 messages are transmitted per real time tracking interval sending. This will allow the tracking system
to process other messages in case many location messages that need to be send back to base.

Example:

There are 130 missed messages saved to memory.
For the first real time tracking interval the unit will transmit 100 locations.
The last 30 messages will be sent after the second real time interval.

7. Serial port data sending using the GSM Modem:

Serial port data sending allows any external device to use the tracking units as communication interface. As
the tracking unit has the TCP/IP protocol build in the external device does not require the protocol to send
and receive data using the Internet to or from any location in the world.
Simple ‘AT’ commands are used for all communication.

Serial port data sending:

Tracking unit must have credits to access the modem using the serial port for SMS and GPRS mode(s).
Send "S". (Capital "S")
Wait for "OK+<mode - 1 byte>" (mode is 0 when in SMS only mode and 1 if in SMS and GPRS mode)

Then send 4 digit password + CR ($0D).
Wait for “>” + CR($0D) + LF($0A).

The serial port has now ‘direct’ access to the GSM modem. Baud speed is set at 9600 and cannot be
changed. Only ‘AT’ commands are allowed, no connection to the internet using dial-up is allowed on this
port.
The tracking unit will monitor the port for data communication.
Type ‘AT COMSTOP’ or ‘at comstop’ to disconnect.
If no data is send (from the serial port to the modem) for more then 60 seconds the port will automatic
disconnect.
During connection the tracking unit cannot send or process any data.

Please note:

In SMS only mode the unit will send all data using SMS. In SMS and GPRS mode the unit will send all data
using GPRS.
The unit still processes SMS messages when connected to the GPRS network. The unit can process and
send SMS messages without disconnecting from the GPRS network.

8. Priority of Messages:

As your tracking system processes many inputs and outputs there are several outputs and inputs that have
priority above others.
In general:

Panic Button – First Priority
All others have the same priority, but reporting of the activation may depend on what input has activated first

if several inputs are activ ated at the same t i me.

This priority setup may delay messages that have less priority.

When changing operating mode from 'SMS Only' to 'SMS+GPRS' the current active commands are
completed first before changing operating mode.

12. Receiving and sending GPRS data:

The GPRS data format for sending is identical to the message format sent using SMS except that the GPRS
has a ‘header’ string at the start off the message. This is for all GPRS data including the ‘CONFIRM’ and
multiple location message.
The ‘header string’ is the IMEI number from the tracking unit GSM modem. The IMEI number is displayed on
the tracking unit or is shown when you exit the diagnostic main menu using ‘Hyperterminal’.

Sample data string received in GPRS mode (without compression):

<IMEI number>,05*850,000,PT35,A,2459.3640,N,12125.2958,E,000.0,224.8,00.8,07:47:26 09-09­05,1.00,80,3F

Sample data string received in GPRS mode (with compression):

<IMEI number>,05*850000PT35A24593640N121252958E00002248008074726090905100803F

Any command message(s) can also be sent to the tracking unit in GPRS mode. The message(s) must be
sent within 2 seconds after any message is received in GPRS mode. The command messages as identical
to the messages sent using SMS.

GPRS errors:

The serial port will output GSM communication and any errors when connection or sending data in GPRS
mode.

Measuring temperature (NTC) using the AUX2 input example:

The AUX2 input voltage (yellow wire) will change when the temperature changes. Most Thermistors are at
normal resistance (in above example we use 10 K) at 25 degrees. So in our example that will be 10K.
The input voltage to AUX2 will then be 1.27 Volt (ADC value will be 128 decimal or 80 hex).

The input voltage is always included in the ‘location message’ and can be configured to activate below or
above set value. Using the WTGAT I/O cable the AUX2 input must be connected to the yellow wire, the GND
to the white wire and the Vcpu to the Brown wire.

Measuring temperature (DS18S20) using the AUX2 input
example:

When the DS18S20 is connected as shown above and enabled in the configuration menu program the
temperature measured is automatic included in every location message.
The WTGAT will measure the temperature when running in normal running mode every few seconds.
When the temperature trigger is activated a location message will be send with the temperature measured
and the activation status. The temperature trigger will deactivate once the temperature goes back and stay
between the low and high trigger value and automatic reactivate again once the temperature goes again
below or above the trigger value configured.
During sleep mode no temperature measurement will be done and cannot activate in sleep mode.
Please note that the battery consumption will be more then using the DS18S20 to measure the temperature.

Measures temperatures from –55°C to +125°C (–67°F to +257°F) +/- 0.5 degree accurate

Example location message data with positive temperature:

05*850,
Shows temperature trigger activated with temperature at 36 (HEX). The temperature value needs to be

converted depending on positive or negative value. In the above sample the temperature is positive (status
code digit 3 is zero and the temperature is 36 hex = 54/2 = 27 degrees

Example location message data with negative temperature:

05*850,
Shows temperature trigger activated with temperature at CE (HEX). The temperature value needs to be

converted depending on positive or negative value. In the above sample the temperature is negative (status
code digit 3 is 8 and the temperature is CE hex = 206 -> (206 – 256)/2 = - 25 degrees

Testing the DS18S20 connection can be done when the WTGAT enters ‘normal running mode’ (when you
exit the diagnostic mode using Hyper terminal). When pressing the ‘T’ or ‘t’ key the WTGAT will display the
temperature m e as ured by the DS18S 20 . Th e DS 18 S 2 0 t em perature tes t will exit automat i c after 60 seconds
or when you press the ‘Q’ or ‘q’ key.

THE CORRECT TEMPERATURE FOR ZERO (00) to MAX 99 DEGREES. This is only limited for the
testing option. Temperature shown in the location message can be from –55 to +125 Degrees.

The complete datasheets for DS18S20 can be downloaded from the ‘maxim’ web site (http://www.maxim­ic.com/).

Using the WTGAT I/O cable the AUX2 input must be connected to the yellow wire, the GROUND to the white
wire and the 3.3Volt to the Brown wire. The cable length is limited to 2 meters max.

Connecting the wire loop cable:

The WTGAT has option to connect external wire. When the wire is cut the WTGAT will automatic power up.
This function will activate and work in any sleep mode configured.
The wire connection must be connected as shown here:

Please Note:

If the wire loop is cut the WTGAT will power up (if not already powered up) and sent Panic activation
message. Once the wire is cut the WTGAT will not power down again. The wire must be restored or

look cable must not be connected to any other cable or have any open wire that can be touched by
hand.

For normal Panic activation there is no need to connect the wire loop cable. The Panic input will activate if
connected (by push button) t o GND. If the WTGAT I/O cable is used then the Panic input is activated when
the ‘Purple’ and ‘White’ wire is connected for more then 1 second.
