I have what might be an elementary scsi question. I have a lot of
hardware and electronics background, but I am new to scsi.
I have an HP 5000i SureStore DAT drive and a Mylex BT-958 card. I also
have a 50 pin ribbon cable to connect the two. My question is, do I
need a terminator at the opposite end of the cable from the
controller.
The controller is auto-terminating, so it will take care of its end of
the bus. According to its documentation, generally the device you are
connecting it to will have built in termination that can be enabled or
disabled. The tape drive documentation, however, does not indicate
that it has internal termination. It suggests that you will need to
put a terminator on the cable if the tape drive is the only, or last device.
A friend of mine told me that some of the newer cards would not
require such a terminator and that I should try it without. I have not
yet done that, but I wondered if someone has experience with this
and could shed some light on it.
Thanks
