Question about SCSI termination using adaptor

I have an external SCSI device (that doesn't offer the
option of internal termination) that uses high-density
68 pin connectors. I have a HD 68 pin-> 50 pin adaptor.
If I attach the adaptor to the output 68 pin connector
and then use an active (or passive?) 50 pin terminator
to the result, will that work properly? Or will I be
subject to the nightmares of an improperly terminated
chain?

Thanks,

Kwad
 
Would be cheaper to open the external enclosure and use a jumper to turn on termination within the device.
 
It wont work if you have any device on the bus that are "wide". The 50 pin terminator only terminates the 'lower' half of the SCSI bus.
 
You need a 68-pin terminator.

Opening the chassis and terminating the device doesn't work properly. The 2 connectors on the outside of the chassis are chained together. Terminating the internal device still leaves the bus improperly terminated.

You need something like this.
 
Terminating the device internally will work.

As long as the device is either the last device on the chain, or the only device on the chain, the bus will be properly terminated at that point.

For Kwad Guy's situation, using a $50.00 external terminator is a convenience, not a necessity.
