The HP A3183A reads the SCSI ID at power up and during selftest in order to determine the selected
target ID of the tape drive on the interface bus. Data Compression Control is not used in this system
application. Terminator Power - When jumper is installed, the device will supply termination power to
pin 26 of the SCSI bus. (Note, this device has no on board termination capability.)
