MISCELLANEOUS TECHNICAL NOTES

The standard SCSI terminators terminate data bits 0-7 on the SCSI bus. The SCSI-wide terminator terminates data bits 8-15 (wide portion) on the bus.

Maximum use of two SCSI connectors is recommended. This means devices should be chained off connectors SC1 & H1, SC1 & SC2 or SC2 & H1, but not all three.
