CU1 to the acquisition card can be found in Appendix The CU1 will emit a beep when connection to a National Instruments acquisition card and PC is not detected. The beep will also sound at powering up until the Helmholtz Coil Control Software is started. -
Page 9: Powering Sequence
Before powering the system, you should ensure that all the connections between the Helmholtz Coil and the PA1, the PA1 and the CU1 and/or CU2 as well as the CU1 to a suitable National Instruments acquisition card (or PXI-system) are done. -
