Title: Difference between Term Power and Terminated
Post by: Rail_Alan66 on December 01, 2024, 01:21:40 AM

I have a CR-503-B CD-ROM in my Amiga 2000 and I'm putting it in the middle of my SCSI chain. Blizzard 2060-> CD-ROM-> SCSI2SD card.  The Blizzard 2060 is terminated.  The SCSI2SD card has the terminated flag set.  The CD-ROM has two jumpers, 'Terminator' and 'Term Power.'  Do I remove both jumpers?  Remove Terminator only? Term Power?

I would presume position of term-power doesn’t matter when termination is disabled.

No that's not true. It's exactly the opposite.

TermPower supplies termination power to the cable. This is required if you have a seperate terminator connected to the end of the cable.

If you use a device to terminate the cable, it should supply power to its own terminator. But you better consult the documentation to be sure.

Ah, that makes sense - thanks for the correction! :)
