Question on SCSI termination

[AU Tiger]

I have three drives on my internal 50 pin scsi connector and I was wondering what drive should have the terminator set. The setup is as follows:

SCSI Card ---- Plextor Burner ---- Toshiba DVD ---- Plextor 40x CDROM

Is it correct to put the terminator on the CDROM? Thanks.

Yes, on a SCSI chain you terminate the last device. In your case you probably jest need to enable the terminator on the Plextor CD-ROM and everything will work fine.

Can termination then be by jumper on the last device? I see scsi terminators, active?, applied to the last connection. I have a hard drive only that I'd like to terminate. Jumper or device?

Since those are just optical drives, then all you need to do is make sure the CDrom drive has it's termination jumper in place. Oh and make sure the terminator jumpers aren't in place on the burner and dvd drive.

For Optical drive and SE hard drives(max 40MB/s throughput) you can just terminate the chain using a jumper on the last drive on the chain.
If you plan to use higher end LVD hard drives(U2W, U160, U320) then you need to have an active terminator at the end of the LVD cable, in order to enable speeds higher than 40MB/s. Of course you can jumper LVD hd's to run in SE mode(and not use an active terminator), but the drive will max out at 40MB/s, even if it's a U160 drive.
