Low Voltage Differential to High Voltage Differential Converter
The LVD2HVD is a low-voltage differential (LVD) to high-voltage differential (HVD) converter. Unlike some converters, the LVD2HVD is true LVD and does not degrade to a single-ended (SE) SCSI bus.
The small format PCB is full speed Ultra Wide SCSI capable and designed for convenient integration into most common enclosures.
- Ultra SCSI capable.
- Initiators and Targets may be placed on either side of the device.
- Does not consume a SCSI ID.
- Transparent operation, Independent of host software.
- LVD side switches to Single-ended mode automatically if plugged into a SE bus.
- Hot-Swap mode, where each side can be electronically isolated.
- Integral Multimode LVD terminators that sense the LVD bus and switch to SE mode as appropriate.
- Supplies terminator power out to each bus via a jumper and restable fuse.
- SCSI bus signals are re-generated and re-timed.
- HVD SCSI peripherals to an LVD or SE controller.
- LVD SCSI peripherals to an HVD controller so that the LVD bus remains true LVD.
- SE SCSI peripherals to an HVD controller.
- Creating bus segments that are electrically isolated from each other
- Bus extending, where an LVD SCSI bus can be lengthened to 100m by adding converters in a serial fashion.
- Enabling Server Cluster.
