Termination Configuration
In the default configuration shown in Figure 2-4, the PXI-8214 switches
SW1-1 and SW1-2 are both set to ON to terminate the SCSI bus. In most
applications, you should use the default configuration. To disable
termination on the PXI-8214, you must set both the SW1-1 and SW1-2
switches to the OFF position. In all setups, both switches should be either
ON or OFF. If the switches are mismatched, the board will function
incorrectly.
