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.

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 medium and Highhigh-speed CAN interfaces.
