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
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).
