External 68 Pin SCSI LED Terminator LVD/SE (Screw Type)
External 68 Pin LED Terminator LVD/SE :
Although LVD is not directly compatible with single-ended, the devices will use multimode drivers that automatically detect the type of bus used and switch into the appropriate mode of operation. This will allow you to use an LVD/SE device on a single-ended bus without having to set any switches or jumpers. Therefore, LVD has been introduced gradually without the loss of the current investment in single-ended devices.
But, it should be noted that the advantages of LVD are lost when a LVD/SE device is used in a single-ended bus. Actually, as soon as one single-ended device is connected to LVD/SE bus, the whole bus switches to single-ended mode with all its limitations.
As with all parallel SCSI alternatives, the LVD SCSI bus must be terminated on both ends. The LVD terminator uses a 1.25 volt source and a few resistors. Currently there are no other termination alternatives for LVD. LVD/SE terminator chips with an auto sense feature that automatically switches termination from single-ended to LVD depending on the DIFFSENS signal are available
