Hi,
I want to Attach two devices on my single SCSI card, I have a LSI53C1000 SCSI Card which is connected to my SCSI hard disk, Now i also want to attach my SCSI DAT drive which is having 50 Pin Connector, How do i do this, as my motherboard (SE7500CW2 Intel make) is not allowing more than one SCSI card on the Board, Please help me out.....

G'day,

In principle you can attach multiple devices to a SCSI controller. The connection should be the same as connecting IDE hard drives, only the connector is 50 pin. I think all you need is a cable with multiple connectors on it. One connector for each device, and one going to the card. Each device then needs an address setting (swithes on the board). You may have to remove or add (can't remember which!) some terminating resistors.
Consult your manual for this.
regards,
Elric

on the every end of the device must be terminated
else you will never get them to work

G'day,

The termination is either passive or active. In the simplest of terms it might just be a set of resistors which looks like an IC or a SIL (single in line) part. This would plug into the card or back of the device. It is not a cable. This, however, only works for short cable lenghts and slower SCSI systems.
The active termination requires power and supplies the necessary termination voltage (as opposed to the voltage produced by termination current running through the resistor). You would have to conslt your manual or dealer. Are you sure that the device or board did not come with any of these?
regards,
Elric
