Cable Accessories

AUX Trigger Cable

This cable allows the NI 4065 to trigger NI switches, third-party switches, and any other external device during synchronous scanning or handshaking scanning.

Note  The AUX Trigger Cable only provides access to AUX I/O Connector Pins 2, 6, and 9, where Pin 2 is Ground and is present in both ends of the cable.
SH9MD-AUX Cable

This cable allows the NI PXI/PCI/PCIe 4065 to control SCXI switches, send measurement complete (MC), and receive external trigger. This cable allows the NI USB 4065 to send measurement complete (MC) and receive external trigger. This functionality allows the NI 4065 to work under both synchronous scanning and handshaking scanning. Refer to Scanning Switch Modules for more information.
