Black Box High-Line terminator terminates both internal and external bus connections. Featuring molded-plastic design for reliable operation it enables you to use a 68-pin wide drive with a standard 50-pin SCSI bus or connect a 50-pin narrow drive to a wide internal ribbon cable. You can also actively terminate unused High 9 lines by using active negated terminators for ultra fast operation. Combination terminators/adapters transfer all the proper signals and actively terminate those not being used.
