Systems, devices, and methods for asset tracking through specialized connectors and specialized casing units are provided. An example system includes an asset tracking device and a specialized casing unit to house the asset tracking device and to connect the asset tracking device to a communication port of an asset. The asset tracking device includes a communication port interface to interface with the communication port of the asset directly, and to interface with the communication port of the asset through the specialized casing unit. The asset tracking device further includes a controller to determine whether the asset tracking device is interfaced with the communication port of the asset directly or through the specialized casing unit, and when it is determined that the asset tracking device is interfaced with the communication port of the asset through the specialized casing unit, configure the asset tracking device to operate in a specialized operating mode.
