The GX6196 features 96 DPST relays which can be individually controlled via the PXI bus and interface via four inter-board connectors to a module board assembly (user supplied). In addition, there are eight parallel digital LVTTL I/O control lines and a serial bus interface which are accessed via an additional board to board connector. Control for all of these digital interfaces is also supported via the PXI bus, providing control for circuitry located on the user defined module board. The figure below details the PXI relay and control board.
