Optim

Optim 3.0 is the reliable freight-transport tracker. It supports GPRS and SMS, integrates easily with LLS sensors, and is rated IP52. Profi 3.0 is built for extreme conditions, with wide voltage tolerance, heavy vibration resistance, IP54, used in mining, construction, and fuel tankers. Profi 3.0 Wi-Fi adds local-network data transfer for sites with no cellular coverage. All trackers carry a 3-year warranty.

Optim 3.0 is the right choice for delivery vans, light commercial diesel trucks, and freight fleets operating in areas with stable cellular coverage. It is the lower-cost tracker in the lineup and integrates with standard fleet management workflows. Profi 3.0 steps up to handle the abuse heavy diesel machinery delivers daily: temperature extremes from minus 40 to plus 85 Celsius, voltage spikes from auxiliary equipment, vibration from off-road operation, and dust ingress from quarries and construction sites. It is the recommended tracker for diesel excavators, haul trucks, drilling rigs, cranes, and tankers. Profi 3.0 Wi-Fi adds a critical capability for remote operations: when the vehicle returns to a Wi-Fi hotspot at the depot or worksite, it offloads buffered data automatically. This is the standard for mining fleets in remote areas, agricultural operations across large fields, and any site where cellular service is unreliable or expensive. All three trackers speak the OMNICOMM LLS protocol over RS-485, which lets partners pair them with OMNICOMM sensors or mix and match with third-party hardware.

Most likely yes. The OMNICOMM LLS protocol is an open industry standard supported by every major telematics terminal manufacturer worldwide. Sensors connect via RS-232 or RS-485 digital interfaces, or via the analog LLS-AF 4 model if your tracker only accepts voltage input. Compatibility covers the major fleet management platforms used across Europe, Asia, Africa, and Latin America.

The OMNICOMM LLS protocol has been the de facto industry standard for digital fuel-sensor communication since the late 1990s. Any modern telematics tracker that handles fuel data can parse LLS messages, regardless of vendor. If your current platform supports digital fuel sensors at all, OMNICOMM hardware is almost certainly a plug-and-play match through the RS-485 interface. For older trackers that only accept analog voltage input, the LLS-AF 4 model outputs a frequency-converted analog signal that bridges the gap. To verify, send your tracker model and firmware version to your regional OMNICOMM business development contact and you will get a compatibility confirmation within a business day. For complex multi-platform deployments, OMNICOMM's integration team and partner network can validate sensor-tracker pairings before purchase.

A fuel level sensor connects to a GPS tracker via an RS-232 or RS-485 digital interface, or via an analog voltage interface for older trackers. The OMNICOMM LLS protocol is an open industry standard supported by virtually every modern fleet telematics tracker, so most installations are plug-and-play. The tracker pairs the fuel reading with GPS location and uploads both to the fleet management platform.

The wiring is simple. The sensor has a four-wire cable: two for power (the tracker supplies 7 to 75 volts) and two for data on the RS-485 bus. The installer connects these to the tracker's matching pins per the tracker's wiring diagram. If a single tracker handles multiple tanks (twin-tank trucks, multi-tank tankers), up to four sensors can be daisy-chained on the same RS-485 bus, each with a unique address. For trackers that only accept analog input, the LLS-AF 4 model outputs a frequency-converted analog signal that bridges the gap. Once wiring is complete, the tracker is configured to recognize the sensor address and assign it to the correct tank, and CalibrateX runs the automated calibration to map sensor readings to actual liters. The whole wiring and configuration sequence for a single-tank vehicle takes a couple of hours, and the LLS protocol means the same workflow applies regardless of the tracker brand.
