The Falcon Cellular is a super-smart, battery-powered tracking device in a rugged IP67 housing - in particular designed for asset location with temperature monitoring.
In the Box
You'll get a Falcon device with two glands for external probe wiring, the PCB is screwed into the housing with four screws, with six screws for securing the housing lid and an pre-installed seal for ensuring an IP67 seal.
One gland will be fitted with a stopper to prevent water ingress when no cable is fitted. DM can supply extra stoppers if both are going to be unused, or as replacements.
Setting it Up
The Falcon uses a micro SIM card – form factor 3FF. The SIM holder is on the underside of the control board, so the device will need to be unscrewed and lifted out of the housing to insert the SIM.
Note: When handling the Falcon be careful not to touch the GPS antenna, to minimise the risk of damaging the sensitive GPS amplifiers with static discharge.
Then open the SIM holder by sliding towards the edge of the board, and place the SIM with the keyed corner facing in and the SIM contacts orientated down to the main board. Then gently press the SIM cover back down and slide towards the middle of the board to latch.
To easily get up and running:
- The SIM should not have a PIN on it, unless you use the device specific PIN.
- The SIM should have credit or airtime.
The Falcon uses three AA LTC Batteries and does not have reverse voltage protection so take care to insert the batteries with the correct polarity, the tabs being the negative terminals.
Note: It is very important to use 1.5V Lithium, or 3.6V Lithium thionyl chloride (LTC) AA batteries. If you use normal Alkaline AA batteries then they will only operate for about 50% of their useful life.
Please see our article here about selecting suitable batteries for the Falcon
It is important that LTC batteries can supply sufficient pulse current. Not all models are built the same!
If in doubt use Energizer Ultimate Lithium.
Once inserted, the LED should flash continuously. If it does not, it means the unit has not yet reset. In this case, remove the batteries for a minute or two to allow any residual charge to drain, and then reinsert them. Failure to reset the unit will prevent proper resetting of the battery life statistics.
The Falcon is fitted with a Coulomb Counter which tracks the devices energy consumption. It is hard to predict the battery life of lithium batteries due to their flat discharge curve, the Battery Meter enables an accurate battery level to be determined for great features such as:
Accurate Low Battery Alerts - Alerts can be set at any level which provides enough time for new batteries to be fitted.
Battery Life Predictions - The Falcon can simply be deployed in the application with the desired settings for a short time (a week or so). The energy usage over this time can be determined, and from there battery life can predicted accurately
Telematics Guru provides a powerful Battery Management Tool
which displays the percentage and provides a battery life estimate.
Once the batteries are inserted, the internal LED will come on and flash. The device will do the following:
- Connect to the server: If the SIM card works the device will connect to the OEM Server and attempt to download any firmware and parameter updates then fetch fresh GPS aiding data.
- Get a GPS Fix: The device will attempt to get a GPS fix. You can speed this up by moving to an area with good GPS signal.
- Reconnect to the server: The device will attempt to connect again to upload the result of the GPS Fix.
If the device does not complete these steps in 10 minutes, it will go to sleep and try again on the next heartbeat or the next trip start. Go to www.oemserver.com/installer and search for the serial number to confirm that it has connected recently.
If the LED flashes but the Falcon does not connect, check the SIM is in the holder correctly and check that the SIM is working. Click here for more Troubleshooting steps.
Opening and Closing the Housing
Once online, all that remains is to seal the housing. Seal the device carefully to achieve the IP-67 rating. Ensure that the clear silicon seal is in good condition, is lying flat, and is not fouled by any plastic debris or other material.
- Close the housing, and gently squeeze it shut. Foam on the lid will compress against the batteries, holding them firmly in place.
- Tighten the 6 screws to a uniform tightness. On the first assembly, the screws may be quite stiff.
- If you wish to replace the batteries and open the housing, be sure to check that the silicon seal is in good condition before closing the housing again.
Installation of I2C probes and sensors

By default, the Falcon is set-up for trip tracking. For those familiar with the Oyster and Remora, the defaults are the same. The following default settings apply:
- Out of Trip: 12 hour heartbeats. This is a GPS point and an upload every 12 hours.
- In Trip:
- Start trip threshold of 250m
- Upload on trip start.
- GPS points every 2 minutes
- Upload every 30 minutes.
- End a trip after 5 minutes of no movement.
- Upload on trip end.
These settings and many more are configurable in the OEM Admin Interface. The defaults provide a good starting point but it is important to monitor and tweak your settings to ensure the battery life is acceptable. Incorrect settings can flatten the batteries quickly.
