Installing the CTM-ONE

Select an installation location that will provide optimal cable routing for external connections to vehicle diagnostic port or power, external sensors, etc. Consider mounting locations that will take advantage of the internal antennas. In some cases, external antennas may need to be used to provide adequate Cellular/Wi-Fi/GNSS operation. Optimal in vehicle mounting locations includes areas that have clear visibility of the sky such as under dash/under window locations.  Be careful not to mount the CTM-ONE in areas where materials would shield radio signals.

The CTM-ONE has accessory covers that can be installed to provide ingress protection for mounting in areas of excessive moisture and dust. These covers also can also provide a degree of tamper protection if mounted correctly with sealed cable glands and fasteners properly torqued. Accessory covers can be secured with #8-32 screws.

Do not overtighten, recommended torque value: 8-10 in-lb

Mounting

The CTM-ONE includes a flexible mounting bracket that has four 5mm mounting holes suitable for #10 screws. Take care not to over-tighten these screws and damage the bracket. Once this has been installed in the required location, clip the CTM-ONE into the 4 tabs of the bracket. The bracket can be used as drill guide template. There are a total of 4 mounting holes (1.75 (44.5 mm)” x 3.75 (95.25 mm)” center to center distance).

Optional Cable Covers

In-Vehicle Installation

The CTM-ONE can draw power from the vehicle CAN Bus (OBDII/J1939). Connect the 8 Pin terminal to the CAN Bus port on the CTM-ONE and connect the other end to the vehicle diagnostic port.

CAN2.0B Bus

Molex Micro-Fit 3.0™ connector #:         

The CAN interface is used primarily to interface to Vehicle sub-systems that support CAN communications.  This includes all small and light duty vehicles manufactured in 2008 and later (ISO15765-4) and heavy-duty vehicles that support J1939.

An accessory OBDII or J1939 Cable is required to interface to a vehicle Engine Control Unit (ECU).  The CTM-ONE can be powered from the CAN port, so no other cabling is required if the vehicle supports either OBDII or J1939 communications.

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