Necessary Squarell hardware
Vehicle Data Interface
The Squarell Vehicle Data Interface is able to collect, process and transmit vehicle signals to the modem of the fleet management systems.
The Vehicle Data Interfaces work together with Special Function Devices such as the DatacliQ, a vehicle data reader and the Trailer ID System (explained below).
DatacliQ: the contactless vehicle data reader
The DatacliQ reads Trailer CAN data (ISO 11992 signals). With a 0-24 Volt bus system capable of obtaining the following information:
- Trailer brake information
- Trailer load information
- Trailer tyre information
- Trailer VIN*
* The Trailer VIN parameter for trailer identification is added in the ISO 11992 protocol in 2014.
Trailer ID System
Get vital data from the trailers across the entire fleet
The Trailer ID System transmits trailer identification to the truck’s fleet management system for identifying the couple status of the trailers in the fleet.
Key features Trailer ID System
- Brand independent solution for the entire fleet
Quick installation using existing wiring
Low power consumption (± 20 mA)
No maintenance (no batteries necessary)
The Trailer ID System: how it is connected
With the Trailer ID System, you can check if the correct trailer is connected to the truck. The system consists of two devices: one Sender (located in the trailer) for sending the trailer ID and one Transceiver (located in the tractor unit) for receiving the ID data.
In combination with a fleet management system, you can get various information about the trailer. For example, the coupling and uncoupling time, the GPS location and the utilisation or cargo of the trailer.
How the system sends and receives trailer data
Trailer ID Sender
The Sender is a tiny device installed inside the rear light cluster of the trailer. The Sender has two wires: one connected to the ground wire and one to the brake signal wire.
Trailer ID Transceiver
The Transceiver is a small smart device installed in the tractor unit. A sense wire is connected to the brake light wire; two wires for power supply and the Trailer ID signal output. There are three output variants: CAN bus output, SFD output for the FLEX and SFD JAE output for the SOLID.
Trailer couple and uncouple messages
When the trailer is coupled to the tractor, the ID Sender sends the trailer ID message to the Transceiver. If the trailer is uncoupled, the system knows the trailer is disconnected.
Support for up to 20 trailers on one road train
The Trailer ID System supports trailer configurations such as long vehicles, dolly trailers, or road train rigs. Up to 20 trailers can be identified in one road train.
Quick installation
Connecting the Trailer ID Sender to the brake light is quick and easy thanks to the pre-crimped connectors. The Transceiver unit comes with tractor specific installation instruction from Squarell to ensure correct installation. If the truck is equipped with an interface device from Squarell, a special transceiver connector can be used to plug the connector into the Special Function Device port on the Squarell device. To test signals during installation, the Trailer ID Transceiver confirms the reception of the Trailer ID signal via an LED.
