Two Epson 1200S on one SCSI line?

Hi,

I just can't get two Epson 1200S working on one SCSI line. Termination and IDs
are OK but I get a buss error when booting. Using one scanner with other SCSI
device works, but only when the scanner is the last device in the line with
termination.

Any suggestions?

best regards

An active terminator offers reduced power consumption, but I don't see
why it would "terminate" better.

Epson explicitly advises not to use external terminator.
Just a thought: could it be that somehow the scanners' terminators are
*always* connected, regardless of what the switch says? That extra
termination will kill a SCSI chain right quick.

This is also my suspicion and it explains why nothing works, if the scanner
is in the middle of the SCSI line.

Check each scanner individually to be sure the ID is not a problem.
Then make sure the addressing is compatable. With two identical
devices you do need to take the addressing into account. And there is
a possibility there will be addressing problems no matter what with
two identical devices on the same cables. Also the drivers for the
devices do need to be loaded before the OP boots. If you are not using
the scnners and have the computer booted it is sometimes possible to
reboot and make things work but not all the time. Sometimes I run two
Nikon 4500s with no problms but I do need to watch the booting.
