Step 2. Configure the Operating Characteristics
The GPIB-SCSI-A is shipped from the factory configured to operate in S
mode. Optional parity checking on the SCSI port is disabled. The SCSI ID
that the GPIB-SCSI-A responds to is set at 5, and the primary GPIB address
is set at 0. Additionally, the GPIB-SCSI-A is shipped from the factory with
a SCSI terminating resistor pack installed. Depending on your system, you
may want to remove it.
Configuration Switch Settings for SW1
The DIP switch at location SW1 on the rear panel is used to configure the
power-on primary GPIB address and SCSI ID of the GPIB-SCSI-A. The
DIP switch has eight configuration switches.
The factory default setting is shown in Figure 2-1. In this figure, the black
side of the switch is the side of the switch you press down.
