Examples of the disclosure enable a set top box to be installed. In some examples, a remote control device, a computing device, and a set top box are provided. The computing device downloads configuration information for a location and receives input from an installer at the location. The set top box includes a remote control interface that receives commands from the remote control device, a local communications channel that transmits data to the computing device, an emulator that emulates the receipt of the commands by injecting remote control keypresses into the remote control interface to issue the commands, and a diagnostic feature activatable over the local communications channel by the computing device after the computing device receives the input to perform verification tests and to return results of the verification tests to the computing device to confirm to the installer that the set top box has been installed correctly.
