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:
Use of external antennas if device is installed in vehicles (please refer to/wiki/spaces/CTMONE/pages/2397241347)
Draw power Power from vehicle CAN Bus diagnostic link connector (DLC) (OBDII/J1939) - no other cabling required
For non-CAN vehiclesvehicles where DLC is not supported/desired, the device can be connected with a DC power cable for direct
connection
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 refer to the CTM-ONE installation overview here.

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.
