Abstract
An apparatus, system and method for testing a peripheral device such that the device can remain installed in a housing and connected to a communication bus such as a SCSI bus. The apparatus, system, and method include a communication port that is connectable to a peripheral device connected to a terminated communication bus. The communication port is connected to a first transceiver and a second transceiver. A microcontroller is also connected to the first transceiver and the second transceiver. The microcontroller is programmed to detect an operation mode for the peripheral device and selectively activate the first transceiver or the second transceiver based on the detected operation mode. The microcontroller is further programmed to perform a logical diagnostic test on the peripheral device using the activated transceiver. A user interface is included to communicate to a user a result of the diagnostic test.
