Appendix B

1260-100X THEORY OF OPERATION

GENERAL

The 1260-100X consists of three PCB subassemblies: VXI
Interface, Option 01T/Passport, and Backplane/Mezzanine PCB
subassemblies.

VXI INTERFACE
PCB SUB-
ASSEMBLY

The VXI Interface PCB assembly serves two functions. It connects
+5V, +12V, and +24V power from the VXIbus backplane to the
1260-100X backplane. It also connects the VXIbus backplane
signals to the

Power Filtering

The power is filtered before reaching Option-01T/Passport
subassembly. The fuses, F1 through F3, are of the surface-mount
type. The fuses used are as follows.
