REMOTE functional explanation

REMOTE is the one box solution offering a vehicle data interface with modem functionality. Its compact design houses all you need to supply your customers with: Squarell vehicle data, Remote Tacho Download, vehicle diagnostics (Tell Tales), driver coaching (DAP) and Event Data Recorder (EDR). Equipped with TCP and MQTT communication protocols, Squarell provides its partners with a versatile telematics solution.

Possible Vehicle Network Connections

  • 2 Hardwired/CANcliQ’s and 2 DatacliQ CAN bus connections with automatic baud rate detection, up to 1000 Kbaud (including 667 Kbaud), Internal 120R terminator connection for CAN port 2.
  • 1 Hardwired and 1 DatacliQ J1708 Vehicle Network connection.
  • 1 Hardwired K-line Vehicle network connection with Slow and Fast initialisation.

We read directly from the vehicle networks and OBD, a brand specific FMS device is not required.

CAN networks , Power and Ignition are accessible via one 10-pole Molex Micro-fit connector, the K-line, J1708 and the analogue inputs are available via one 8-pole Molex Micro-Fit connector on the front of the device.

Vehicle Protocols

For CAN bus we support J1939, ISO11992, NMEA 2000 and all manufacturer specific communication protocols. For J1708 the J1587 and J1922 protocols are available. For K-line the ISO 9141 and ISO 14230 variants are available. Connect the ISO11992 Trailer CAN bus via a DataCliQ on SFD port A or B.

Micro B USB Port

The Micro-B USB port can be used to upload sotfware into the device. When this USB port is connected to a Fleet management Tablet, the REMOTE represents itself as a Serial port under DCF control.

Analogue Input Ports

2 analogue inputs can measure analogue signals up to 30 VDC with a 1 mV resolution or can be used to read 2 digital input signals. The sample rate is 10 ms.

Wireless Network Connections

The Modem of the REMOTE has a 2G band for GSM 850 and 900 MHz and DCS 1800, PCS 1900 MHz and also a 4G LTE-M band with 2G fall-back.The REMOTE switches automatically to the alternative band when the present network fails. The modem antenna is built-in.

Wireless Network Protocols

The user can select 3 communication protocols for the REMOTE: TCP, MQTT and HTTPS. TCP and MQTT are more commonly used but we have implemented the HTTPS protocol for high security applications such as military vehicles and money transport vehicles.

Data transmission

The user can select the envelope mode for data transport, the data transmission is than more efficient. For the data transmission a 4 MB data buffer is available. Due to the combination of both features a lot of data can be stored for a long period of time and accelerated the Tacho Download sigificantly.

SIM card

A Nano SIM card can inserted on the top of the device.

Global Navigation Satellite System (GNSS)

The GNSS receiver in the REMOTE is designed to receive signals from different satellite systems like GPS, GLONASS, Beidou and Galileo. For a good location reception, the antenna must be placed outside the vehicle. The location data rate in the REMOTE depends on the speed and movement of the vehicle. Our algorithm ensures high accuracy on the map at a low data transmission rate!

Second Micro Processor Unit

In addition to the standard DCF processor, the REMOTE has a second MPU. The versatile configuration, the different communication protocols, the data transmission envelopes and the wake-up, sleep and deep sleep states are handled by this MPU. A smart helper.

Sleep and Wake-up

The REMOTE is able to sleep and still monitor the CAN bus for activity, it can even be in deep sleep and still be awakened by motion or time to perform a task.

Real Time Clock

The Real Time Clock has its own battery that keeps the RTC active during power off or sleep mode. The REMOTE can be woken at a time or a time interval. The RTC will synchronise on Google NTP.


The REMOTE has a 3-axis accelerometer that can detect movements of the device (in a vehicle or trailer) for theft detection. Even in deep sleep mode the REMOTE can wake-up on movements and send a warning to the home base.

Special Function Devices (SFD)

On the 3 SFD ports several Special Function Devices can be connected like the DatacliQ, the Driver Awareness Panel (DAP), the Power Output Module (POM) but can also be used internally by the extension board. For example an RS-232 port. The SFD ports A, B and C are accessible via 3 Molex Micro-Fit 4-pole connectors on the front of the device.

Power Supply acc. to ISO 6737-2

The Power Supply of the REMOTE is designed according to the automotive power supply standard ISO 6737-2. The supply voltage range is 10 – 30 Vdc. The average power consumption is at 24Vdc 50mA, during deep sleep mode the power consumption is 24Vdc 5mA.


CE, E4, UKCA, RoHS. According to the regulations, the REMOTE is tested once a year by a certified body for the E4 certificate and is therefore allowed to communicate on vehicle networks.

Physical characteristics

The device is 100 x 100 x 20 mm and weighs 130 grams. Due to the high requirements, -40…85 deg C, the components are long life and automotive grade, the housing is UL94 V-0 flame retarded and has an IP40 protection rate.

Country of origin

The device is entirely designed and produced in the Netherlands.


A group of highly educated automotive engineers support the REMOTE with an extended manual, diagnostic and upload software iControl and FOTA. We provide a standard 2-year warranty on the REMOTE. The manual and configuration is available by reading the QR code on the back side of the device.

Firmware Over The Air (FOTA)

Squarell’s FOTA system is a HTTPS API through which the REMOTE can download necessary files for updates. A FOTA session is always initiated by the REMOTE and the FOTA server responds. The connection is encrypted.

Battery Pack

One option is an external Battery Pack. If the REMOTE also has a monitoring task and needs to be woken up by movement or activity on the CAN bus, an external battery pack is desirable. 1, 2 or 3 x 2600 mAh cells can be connected. The REMOTE can generate 20 days heartbeats on 1 cell. This battery package is charged by the REMOTE itself.
