A communication channel that is accessible when the product is entirely assembled, but appears to be, and functions like, configuration jumpers to the end user. The communication channel utilizes the terminals of a configuration jumper block as communication paths to an interface device. The terminals of the configuration jumper block may be wired differently depending on the desired function (i.e. send data, receive data, etc.) of the terminals. The configuration information needed by the device is read from the terminals of the configuration block when the communication channel is not active. Switches on the interface device are used to set the configuration information. Configuration jumpers that can be used are the Master, Slave, and Cable Select signals for an ATAPI interface.
