How to Choose the Best SCSI Cables
Terminators and Signal Integrity
SCSI requires terminators at both ends of the bus to prevent signal reflections. While some devices have built-in terminators, others require external terminator packs. If you're connecting multiple devices, ensure your termination setup is correct. Using the wrong type of terminator or an improperly terminated bus can lead to intermittent connection issues or complete failure. Always consult your device manuals regarding termination requirements.
Frequently Asked Questions
What is the difference between SCSI and IDE cables?
SCSI cables are generally more robust and support higher data transfer rates and longer cable lengths compared to older IDE (PATA) cables. SCSI also allows for more devices to be connected on a single bus and offers more advanced features for device management.
How do I know which SCSI cable connector I need?
You need to identify the connector types on both your SCSI host adapter (controller card) and the peripheral device. Common connectors include 50-pin Centronics, DB-25, HD-50, and HD-68. Match the cable's connectors to those of your hardware.
Can I use a longer SCSI cable than recommended?
While technically possible, using a SCSI cable longer than the recommended maximum (often around 1.5 to 6 meters depending on the SCSI standard) can lead to signal degradation and data errors. It's best to stick to the specified lengths for optimal performance.
What does 'wide' mean in the context of SCSI cables?
'Wide' SCSI refers to cables that can transfer data over a wider data path, typically 16 bits, compared to 'narrow' SCSI's 8 bits. Wide SCSI cables usually have 68 pins, allowing for significantly faster data transfer rates.
Do I need terminators with every SCSI cable?
Terminators are essential for the SCSI bus to function correctly, but they are not part of the cable itself. They are placed at the physical ends of the SCSI chain. Some devices have built-in terminators, while others require external terminator packs. Consult your device documentation to determine your specific termination needs.
