And Drive To The Backplane - National Instruments VXI-1394 Getting Started

Figure C-7. Receive External CLK SMB with 50
Figures C-8 and C-9 show two configurations for driving the external CLK
SMB from the VXIbus CLK10 signal by changing switch S3 to its alternate
setting. Switch S6 must be in its default position for these configurations.
Signal termination is not an issue when driving the signal, so the position
of S2 does not matter. The difference between these two configurations is
whether to use inverted or non-inverted polarity when driving the signal.
