connected. The nomenclature on the CIO-SSH16 corresponds to CIO-DAS16 signals.
2.4 ANALOG INPUT BOARD SETUP
The analog input board must be configured for single-ended input. If the board you
are using with the CIO-SSH16 supports both 8 channel differential and 16 channel
single-ended configurations, set the board to 16 channels single-ended.
You may also need to configure a jumper on the analog input board to supply the
sample-hold signal to the CIO-SSH16. The SSH16 must have a SAMPLE / HOLD
signal in order to trigger the LF398 sample & hold chips. The LF398s sample the
input signal on each channel when the analog input board samples channel 0 and each
channels signal is held until the next time channel 0 is sampled.
Refer to the users manual for the analog input board you are using for details
regarding configuration of the analog input and the sample / hold signal output.
2.5 GAIN SWITCHES
Each amplifier has a quad DIP switch located
nearby. The four switches control the gain of one
amplifier. The gain settings are additive so a total
of 16 different gains (including 1) are possible.
The gain of a switch is added when the switch is to
the left and not added when the switch is to the
right.
