novice: can't see a sdlt drive

dear ng
i have a external compaq sdlt 110/220 gb (scsi lvd/se) with a adaptec 29160
scsi-adapter running on a w2k3 server. windows does not recognize the
streamer. can you please help:

1) do i need a terminator for the sdlt drive ?
2) do i need a special scsi cabel to connect the drive to the adapter
3) any ideas why the drive does not show up in windows (the 29160 seems to
work, i've already connected a 4mm dat drive to it and it runs)

thanx alot
tim
