3.0 SIGNAL CONNECTION
3.1 CONNECTOR DIAGRAM
The CIO-SSH16 inputs are screw
terminals which will accept 12-22 AWG
wire.
Each channel has a screw terminal for
signal high, signal low and ground.
3.2 ANALOG INPUTS
Analog inputs to the CIO-SSH16 may be connected in two different configurations.
In order of complexity, these are Floating Differential and Differential.
WARNING - PLEASE READ
Measure the voltage between the grounds at the signal source and
the PC. Use a volt meter and place the red probe on the PC ground
and the black probe on the signal ground. If there is more than 10
volts, do not connect the CIO-SSH16 to this signal source because
you will not be able to make any reading. If the voltage is more
than 30 volts, DO NOT connect this signal to the CIO-SSH16
because it will damage the board and possibly the computer.
3.3 FLOATING DIFFERENTIAL
A floating differential input is two wires from the signal source and a ground reference
resistor (10 Kohms is a typical value) installed at the CIO-SSH16 input. The two
signals from the signal source are Signal High (CH# HI) and Signal Low (CH# LO).
The reference resistor is connected between the CIO-SSH16 CH# LO and LLGND
pins.
