Compact. Intelligent. Built Different.
What you see on the outside is a sleek, compact matte black enclosure that plugs directly into your truck's diagnostic port. What's inside is where the real story is - a fully custom-engineered PCB loaded with the latest generation chips, purpose-built for the demands of commercial trucking. Not a rebranded import. Not an off-the-shelf solution with our name on it. Every component, every design decision, every line of firmware - made in-house, by Americans, for American carriers.
A latest-generation ARM Cortex application processor handles simultaneous ELD logging, telematics data processing, GPS positioning, and cellular transmission without lag or data loss - even under continuous, round-the-clock commercial operation.
Our integrated high-sensitivity GPS module features a dedicated ceramic patch antenna for fast satellite lock and accurate, continuous positioning through city corridors, loading docks, mountain passes, and low-signal rural stretches.
The latest-generation LTE chip keeps the device connected to the Silverline cloud platform in real time, with automatic network switching to maintain the strongest available signal wherever your truck operates.
Enables fast, stable wireless pairing between the device and the driver's mobile app for duty status management, roadside inspection data transfer, and DVIR submissions - no cables between device and phone required.
Direct, high-frequency Engine Control Module communication pulls real-time engine data - RPM, fuel rate, coolant temperature, oil pressure, fault codes, odometer, and engine hours.
All on-device data is encrypted at rest using AES-256 standards. Secure boot architecture ensures only authenticated Silverline firmware runs on the hardware - tamper-resistant and fraud-proof by design.
Every chip, capacitor, and connector on the Silverline PCB is rated for the full automotive temperature range (-40°F to +185°F) and selected for long-term vibration resistance.
Plugs directly into the truck's diagnostic port. No wiring harness, no tools, no technician required. Fully operational in under 5 minutes from the moment it arrives.
“Most ELD devices on the market are bare-minimum boxes — they log hours and stop there. We designed the Silverline ELD to be the intelligence layer of the entire truck.”
Because we design and control the hardware, we control the data depth. The Silverline device captures everything your fleet operation needs — continuously, securely, and instantly available on your dashboard:
