SW1 Default Mode Switch Settings

Switches 1 through 3 are used to configure the SCSI ID. Switch 1 is the most 
significant bit, and Switch 3 is the least significant bit. For example, if Switches 1 
through 3 are set to OFF, ON, ON, the SCSI ID is 3.

Switches 4 through 8 are used to configure the power-on primary GPIB address. 
Switch 4 is the most significant bit, and Switch 8 is the least significant bit. For 
example, if Switches 4 through 8 are set to OFF, OFF, OFF, ON, OFF, a primary 
address of 2 is indicated. The largest primary address that can be set is 30.

The default settings of Switches 1 through 3 are ON, OFF, ON, respectively, to 
select the SCSI ID of 5. Switches 4 through 8 are OFF, indicating that the GPIB 
primary address of the GPIB-SCSI-A is 0.

Configuration Switch Settings for SW2

The DIP switch at location SW2 on the rear panel in Figure 3 is used to configure 
the mode of operation for the GPIB-SCSI-A. These switch settings should 

not

 be 

changed for use with the Sun SPARC system. Figure 3 shows the factory default 
settings. Make sure that these switches are set as shown in Figure 3. If they are not, 
set these switches as indicated.
