SSH OUT is synchronized to the analog input boards S&H chip and the channel select
MUX. When the analog input board samples channel 0, each of the LF398s on the
CIO-SSH16 also samples the signal on its input. Each of the LF398s then switches to
HOLD mode and the analog input board acquires this “held” signal from each
channel. The CIO-SSH16 remains in HOLD mode until the analog input board
samples channel 0 again.
