Introduction Page 8
Understanding SCSI
Connections
Read the followi ng sections t o determi ne how to set up you r SCSI devices and whet her you need any optional S C SI c ables.
SCSI chain
The SCSI inte rf ac e allows you to con nect up to seven de v ic es (su c h as a scanner, hard disk, CD-ROM, and so on) to the computer. This arrange m ent is often ca lled a “daisy c hain.” On ly th e f irs t SC SI device in the chain is connected to the computer; each of the other devices is connected to another SCSI dev ic e.

Understanding SCSI Connectio ns Page 9

SCSI cables
If you are us ing a SCSI ca ble other than the one pro v ided, the le ngth of the cable must not e xceed 9.8 feet (3 meters) to maintain complianc e with SCSI-2.
If you are connecting multiple SCSI devices to your computer, you may need to purchase SCSI cables before setting up your SCSI chain. Be su re t he SCSI cab le c onnectors are suitable f or your hardware, depend ing on the mak er of your SC SI device an d SC SI interface board.
To connect the scanner to another SCSI device, the length of cable must not exceed 19.7 feet (6 meters); otherwise the system may not work properly.
SCSI ID
Each device has a SCSI ID number: the SCSI adapter in the compute r is usually nu m ber 7, and ea c h of th e other dev ic es m us t have a differ ent number between 0 and 6. The EPSON Perfection 636 default SC SI ID number is 2.

SCSI termination
The first device and the last device in the chain (not inc luding the adapter) must have a terminator. No other device can have a te rm inator, or if a terminator does exist, it must be turned off or removed . Th e EPSON Pe rf ec t ion 636 terminator is located at th e rear of the scanner . The default position of the termination switch is ON . D o not use an external te rm inator with the EPSON Perfection 636.

Make sure the scann er is tu rned off before c hanging th e SCSI ID number.

Setting the SCSI ID Number

The scanner’s default SCSI ID n um ber is 2. If you add the scan ner to a system in w hic h one of your SCSI dev ic es already ha s S C SI ID 2, you can chan ge t he ID numb er t o an unused num ber using th e rot ary switch at the rear o f the scanner. See the table on the next page for a guid e t o SCSI ID nu m bers. Then fo llow t hese steps t o c hange the ID number:
1 Turn the sc anner off.
Do not set the SCSI ID to an ID number that is already assigned to another device ot herwise the computer, scanner, and other devices will not operate prope rly .
If you are us ing Window s 98, see Changing the SCSI ID Numb er in Window s 98 for more inform at ion.
