A shared resource is a device on the tester or DIB that is connected to an instrument or relay driver module and shared by multiple sites. To specify a connection between a shared resource and an instrument channel or relay driver module control line, use the following criteria to decide how to define a shared resource in the pin map.

  1. If the resource is a relay:
    1. If there is a single relay shared by all sites, define a system relay.
    2. If there are multiple relays in which each relay is associated with multiple sites, define a site relay.
  2. If the resource is not a relay:
    1. If the resource is shared by all sites and you do not need to burst patterns to the resource using an NI-Digital Pattern instrument, define a system pin.
    2. Otherwise, define a DUT pin.
