PURPOSE: A backplane board is provided to enable to install a wide ultra 2 low voltage differential SCSI device having enhanced functions rather than a conventional wide ultra SCSI device so that it can support a SCSI speed of up to 80 MB/s, connect at most 15 SCSI bus device and extend a SCSI bus length of up to 12 meters. CONSTITUTION: The backplane board, one PCB board, comprises a high density SCSI 68 pin connector(200), a SCSI bus, a plurality of wide ultra 2 low voltage SCSI devices(210), and a terminal(230). The high density SCSI 68 pin connector(200) receives signals from a SCSI controller. The SCSI bus integrates a plurality of wide ultra 2 low voltage differential SCSI devices(210) with the connector(200) within the backplane board to connect to one bus. The wide ultra 2 low voltage differential SCSI devices(210) are serially connected. The terminal(230) is connected to a final device among the wide ultra 2 low voltage differential SCSI devices(210) for connecting to an external device and transmitting control signals or data signals to the external device.
