The CTM-500 uses external antennas for cellular, Wi-Fi and GNSS. If the CTM-500 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-500 may be obstructed from a clear view of the sky, Cypress Solutions recommends:
Draw power from vehicle CAN Bus (OBDII/J1939) - no other cabling required
For non-CAN vehicles, 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-500 to power via the vehicle’s OBDII or J1939, place the CTM-500 on the dashboard, under the seat, on the window, or any other suitable position, and attach the external antenna to a window. This installation can be completed in roughly five minutes with the wires hidden.
