    description Cheetah 10K.7 SCSI drives are multimode devices. That is, their I/O circuits can operate as either singleended or low voltage differential drivers/receivers (selectable using the I/O "DIFFSENS" line). See ANSI Standard T10/1302D for detailed electrical specifications. 9.7.1 Multimode

    Single-ended drivers/receivers The maximum total cable length allowed with drives using single-ended I/O driver and receiver circuits depends on several factors. Table 18 lists the maximum the transceiver to the connection to the mainline SCSI bus. Cheetah 10K.7 SCSI Product Manual, Rev. D 81
