d)Connections For The 9 Pin D Sub Connector
Using a suitable mating connector the pins of the integrated connector should be wired as follows:
Connecting To The Integrated 9 Pin Connector
Pin Out of Integrated
Connector
PIN 3 should be connected to the Positive of the power source.
PIN 4 should be connected to the Negative ( Ground ) of the power source.
PIN 2 provides the signal output and should be connected to the positive terminal of the display, data acquisition system or voltmeter.
PIN 8 is the signal negative (ground) and should be connected to the negative (Ground) terminal of the display, data acquisition system or voltmeter.
Pin 6 is the input signal and should be connected to the positive terminal of the voltage source. The
Pin 7 is the input signal negative (ground) and should be connected to the negative (Ground) terminal of the voltage source.
Pins 1, 5, and 9 are not used.
Caution: Avoid high voltage static discharges to the input signal connection. Do not short the input/output signal pins or allow them to contact the power connections at any time. DAMAGE WILL RESULT!
