I/O Connector

♦NI5 102 (PCI,ISA, PCMCIA, USB)

TheseNI 5102 devices have two standard BNC female connectors for CH0

andCH1 analog input connections, one standard BNC female connector for

the TRIG channel, and two standard SMB female connectors for the

multipurpose digital timing and triggering signals, PFI1 and PFI2.
