Rancho RTLVD-SEP Ultra2 SCSI Expander The RTLVD-SEP is an external Wide Ultra2 SCSI (Fast40) multimode expander that converts narrow 8-bit single-ended SCSI to wide 16-bit LVD. It allows single-ended peripherals to be used on an LVD bus without limiting the transfer speed of the Ultra2 bus to that of the Ultra SCSI bus.A multimode feature allows the expander to operate in either single-ended or LVD mode. One unit can be used to extend an Ultra SCSI bus up to 40ft, or two can be connected back-to-back for extensions up to 120 ft.Additional info from 1998 press release:The external WIDE Ultra2 SCSI (Fast40) multimode expander connects to any WIDE low voltage differential (LVD) bus via a 68-pin high-density cable. The RTLVD-SEP expander converts narrow (8-bit) single-ended SCSI to WIDE (16-bit) LVD to allow single-ended peripherals to be used on an LVD bus without limiting the entire Ultra2 SCSI LVD bus (80 MB/s) to Ultra SCSI bus (40 MB/s) speeds. Single-ended devices will operate up to Ultra SCSI speeds. The RTLVD-SEP can also be used to extend a narrow single-ended Ultra SCSI bus to double its total length up to 40 feet (12 meters). The multimode expander can be powered from remote termination power to provide the 5V power source. A power connector is provided for an external 5V power source when needed. Ships FAST with USPS
