Vehicle Productivity, Security, and ELD Compliance
The 66xx family of beacons includes the following models:
• 6600 – 3G with external antenna
• 6601 – 3G with internal antenna
• 6650 – 4G (LTE) with external antenna
• 6651 – 4G (LTE) with internal antenna
• 6681 – 4G (LTE) with internal antenna
These versatile GPS tracking beacons are designed for fleet management needs in
all commercial vehicles. The 66xx connects directly to the vehicle's Electronic Control
Module (ECM) through the engine diagnostics port.
The beacon forms the on-board recording portion of Contigo's compliant Electronic
Logging Device (ELD) solution for Hours of Service (HOS) and Driver-Vehicle Inspection
Report (DVIR) logging, by supplying all required data via Bluetooth to the ELD display.
Combined with our commercial mobile monitoring portal, subscribers can manage
and view the location of any or all vehicles in a fleet, run a variety of valuable reports,
and manage vehicle maintenance alerts.
Antenna Configuration
The 66xx beacons have a combined GPS/cell network
antenna module. The 6600 and 6650 models use an
external antenna attached with FAKRA connectors, while
the 6601, 6651 and 6681 are equipped with an internal
antenna housed within the beacon.
For either configuration, the antenna must be positioned
in the vehicle so that it has a clear signal path to as much
of the sky as possible, without metal obstruction. For
internal antennas, the beacon itself must be positioned
properly for good signal reception.
