In-Vehicle

The CTM-ONE supports the option of internal antennas for cellular, Wi-Fi and GPS (GNSS). If the CTM-ONE is mounted with a clear view of the sky, a single connection point to the vehicle is all that is needed between the device and the OBDII or J1939 port of the vehicle. For other mounting scenarios where the CTM-ONE may be obstructed from a clear view of the sky, Cypress Solutions recommends the use of an external GNSS antenna.

The most effective installation method we recommend is to connect the CTM-ONE to power via the vehicle’s OBDII or J1939, place the CTM-ONE on the dashboard, under the seat, on the window, or any other suitable position, and attach an external antenna to a window. This installation can be completed in roughly five minutes with the wires hidden.

Please find a graphical illustration of the use of internal vs. external antennas below.

CAN2.0B Bus

Molex Micro-Fit 3.0™ connector #:         

The CAN interface is primarily utilized to connect to vehicle subsystems that support CAN communications. This includes small and light-duty vehicles manufactured in 2008 and later (ISO 15765-4), as well as heavy-duty vehicles that are compatible with J1939 protocol.

To interface with a vehicle's Engine Control Unit (ECU), an accessory OBDII or J1939 cable is necessary. The CTM-ONE can be powered directly from the CAN port, eliminating the need for additional cabling if the vehicle supports OBDII or J1939 communications.

The CTM-ONE supports both Medium and High-speed CAN interfaces, as well as Single Wire CAN.
