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.
