Trek Transponder sends precise messages and reports to you advising of problems on your boat by SMS text message. The messages can also be replies to your messages or confirmation of settings.

All the most important commands are  easy to remember “One Tap”commands.  That means you only need to SMS text one letter most times to have the Trek Transponder carry out your command. Here are the “one tap” commands,  and please read further down the page for real examples.

A for Arm (when you leave your boat)

D for Disarm (when you board your boat)

S for Status (full report – check everything)

P for Power (check batteries and shore power)

E for Entries (check security)

B for Bilge (check bilges)

L for Location (check location)

M for Movement (check distance from mooring)

SS for Sea state/ listing (check is boat stable)

One tap commands to get a picture from Camera 1 or Camera 2 are Q and W respectively.

Read below to see real examples:

 

 

Status Command

Sending the word STATUS or (S for short) to your Trek Transponder in an SMS text message will cause your Trek Transponder to return a summary of whats happening on board your boat.

What appears on the Status report depends on what model Trek Transponder you have, whether any functions are turned off, and if you have renamed them.

In the example the boats location is provided and its distance from mooring, battery and charging levels are shown, bilge dry or not, security status, pitch/roll/listing state and relay output positions.

Also in this example many of the inputs and functions have been renamed.

Arm Command and Alarm Messages

When you leave you boat you send the Arm command (or A for short). The Arm command can be cancelled any time by sending DISARM (or D for short).

The Arm command causes the Trek Transponder to record you boats location, turn OFF any inputs that are already in Alarm mode (“Active alarms disabled”) and be ready to protect you from problems by sending you alerts should something go wrong.

If an Alarm condition occurs, depending on what model Trek Transponder you have and its settings, The Trek will send an Alarm message to you and up to 5 other numbers, send photos from the cameras to you, call you, and send copies of the event to email. If one of the inputs designated as “security” triggers the Autorelay will also turn ON for 5 minutes. This is commonly connected to a siren and alarm blinking light.

When you get an alarm you are notified as to what it is, and the same message is sent to any numbers in the Add Number memories. These are typically another crew member, partner or security company. The example alarm shows that PIR2 has detected an intruder.

 

 

Send Alarms to Five Mobile Numbers

Trek Transponder can send an alarm SMS text message to 5 different mobile numbers. They are stored in memories AN1 … AN5.

For example, if you want to add a number to receive alarm messages into memory 3 send an SMS text message commencing AN3 followed by the number you want to add.

You can check the numbers in the list any time by sending an SMS text AN? to the Trek Transponder. It will reply with the list.

 

Location Command

Trek Transponders (except E100 model) contain an accurate GPS which monitors the boats position once per second.

If the boat moves out of an area designated by you you will receive an an Alarm that the boat has moved too far.

You can see your boats location on Google Earth any time by sending SMS text message LOCATION to the Trek Transponder (or L for short) command.

 

Location Geofence Alarm

Every one second Trek Transponder  checks your boats location. It compares that location to a distance limit that you can set commonly called “Geofence”.

If your boat comes adrift, is stolen or anchor/mooring drags  and moves outside the Geofence limit you will receive an Alarm.

Trek Transponder also sends a Google Earth link with the Alarm message so you can immediately see where your boat is to recover it.

In the example the boats Geofence limit was set to 10m. When the boat moved outside that limit to 13m an Alarm message was sent.

 

 

 

Dragging Anchor or Mooring

Trek Transponders check your boats position once per second to ensure it has not moved outside your specified Geofence area.

Additionally your boats position is recorded every 30 seconds once you have sent the Arm command.

This is so you can review your boats movement over the last 10 minutes to check if your anchor is dragging while cruising (see Anchor Watch Alarm),  check that  your mooring is stable or check that your boat hasnt come adrift.

To view your boats last 10 minutes movement send the SMS text command MOVED? (or M for short).

In the example the boat has moved 28m. If it moves past the 50m limit an Alarm will be sent.

 

Low Battery or Shore Power Fail

Trek Transponder monitors your battery voltages and charging system (shore power) once per second.

Each battery has a low voltage alarm limit and an over charge voltage alarm limit. These are adjustable to suit battery type and climate if you wish.

The charging system is also monitored. If your shore power fails you will get an “AC OFF” Alarm. You can rename AC to “ShorePWR” if its easier to read.

Because the solar panel voltage is totally variable there is no alarm limit on that.

In the example  there are three Alarms, AC OFF Alarm and following that Battery 1 and Battery 2 are low.

 

 

Different Voltages for Battery Alarms

Trek Transponder allows separate independent setting of low voltage and over charge alarm voltages for all four battery inputs.

This allows for incorporation of different battery types on your boat. For example Lithium Batteries have quite different acceptable high and low terminal voltages for different states of charge when compared to SLA.

(This feature also allows expert users to re-purpose an input – the limits and gain can be programmed along with rename)

 

 

Automatic Reporting

By using the report function you can receive a report fully automatically from your boat from hourly to 24 hourly.  So you can keep a check on an important issue.

For example you may want to check that batteries are charging correctly so will command Trek Transponder to send you a Status Report every hour. Of course you can manually request a Power status report any time (P for short)  but Trek Transponder will not forget.

The report can be Status or a photo from CAM1 or CAM2. For example you can set the Trek Transponder to send you a Status Report every morning.

In the example the Trek Transponder will send a photo from CAM1 to you every 24 hours.

 

Email

Trek Transponder can Email you date and time stamped copies of all events including optional camera images.

This is especially handy for record keeping for maintenance and  commercial operations. The boats movements for example can be easily checked, security breaches are timed and dated.

SMS text the Trek Transponder your email address then command Email to ON and it works. That simply.

 

Capture Photos of Intruders Automatically

Trek Transponders Cameras can be set such that they will all take a photo when an Alarm occurs on board.

For example the cameras can be  triggered by a PIR Intruder sensor so you can see who is onboard. Or if you have a worrisome bilge leak problem you can place a camera in the bilge and set the cameras to trigger on Bilge Alarm.

Remotely Turn ON/OFF Devices Onboard

Trek Transponder has three 5A output relays. The first relay called “Autorelay” is reserved for a siren or flashing light and turns ON for 5 minutes if a security input is triggered. You would typically have your siren or flashing light wired onto this relay.

The second two relays are Relay 1 and Relay 2. You can simply turn these relays ON and OFF by command. Common uses are to remotely turn OFF and ON your deck lights or turn OFF and ON refrigeration. But they can be used for many other purposes.

The example shows deck lights being turned ON by turning ON relay 1. This is done by sending the SMS text message RELAY1 ON to the Trek Transponder. You will get a confirmation that it is ON. At any time you can check which relays are ON or OFF by sending the SMS text message R?
