System Hardware
2.1 System Schematic
The QNET Physics and Dynamics provides the communication interface with the NI ELVIS II for the electromagnet
release commands and encoder ports. The interaction between the different system components on the QNET
Physics and Dynamics is illustrated in Figure 2.1. The NI ELVIS II is interfaced to the PC or laptop via USB link. The
NI ELVIS II block reads the angular encoder inputs of the catapult axis and the pulley on the sliding mass arm. It
also commands the electromagnets to release the catapult arm and the sliding mass.

The schematic given in Figure 2.2 illustrates the main QNET Physics and Dynamics components and how they
interact with the NI ELVIS II.
