Termination
When this unit is the only device on the SCSI chain, or the last device
on the SCSI chain, it must be terminated.
External: attach the terminator to the SCSI connector not being used.
Internal: Default is terminated. When the termination pin jumper is
“off”, the unit is terminated. When the terminator pin jumper is “on”, the
unit is not terminated.
(1) External units come with an external terminator as shown in the
above diagram. Internal devices come with termination pins, as
shown in the right hand side of the above diagram.
Other Jumper Pins
(1) Jumper off: all three slots are active. Jumper on: only SmartMedia
and CompactFlash are active (type III slot is disabled).
(2-3) Vendor unique usage
(4) Jumper on: firmware rewrite mode. Jumper off: standard use.
firmware cannot be rewritten with jumper off. Jumper should remain off
when the unit is in “regular use”. Unit cannot function normally with
this jumper on. Jumper is only to be “on” when rewritting firmware.
