Setting The Scsi Id Number - Epson 1200 series User Manual

SCSI Cables
You may need to purchase SCSI cables before setting up your SCSI
daisy chain. Be sure the SCSI cable connectors are suitable for your
hardware, depending on the maker of your SCSI device and SCSI
interface board.
SCSI ID and terminator
Each device has a SCSI ID number: the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also, the first device and the last device
in the chain (not including the computer) must have a terminator.
No other device can have a terminator, or if a terminator does
exist, it must be turned off or removed.

Setting the SCSI ID number

The scanner's default SCSI ID number is 2.
If you add the scanner to a system in which one of your SCSI devices
already has a SCSI ID of 2, change the ID number to an unused
number using the rotary switch. See the table below as a guide.
2-10
Setting Up the Scanner
The SCSI ID rotary switch
is located at the rear of
the scanner.
