DC Power Supply

A 3-wire DC power cable (comprising Ignition, Power, and Ground wires) is designed to connect to a DC power source with a voltage range of 7 to 32 VDC.

Certain DC power accessories may come with a 4-wire bundle; in such cases, the 4th wire, typically coloured Green, can be disregarded and left unconnected.)

Connecting the Ignition line enables the CTM-500 to transition into standby/suspend modes, facilitating low-power operation.
