Note that the test lead color matches the channels in the software. The colors reflect the resistor color
code for numbers 0–7. The numerical channel number is on the white heat shrink at the ends of the
leads. The lead ends are terminated with a Molex 0016020086 crimp connector for connection to typical
.100-inch spaced headers/pins. The 2x4 plastic housing is Molex 0022552081.
Signal Integrity with the 2x4 Harness
The 2x4 harness has a ground lead for each signal. When signal integrity is a concern (e.g., working with
high-speed digital or analog in the presence of cross-talk sources), connect a ground for each signal.
Connect noisy digital inputs to leads as far as possible from leads connected to sensitive analog
measurements.
Connecting the 1x9 Harness
If you have the original Logic or Logic 16, then you have one or more 1x9 wire harnesses. These
harnesses are colored according to the resistor color code for 0–7. The colors match the channel colors
in the software. The ground wire is grey and has a GROUND label on the white heat shrink. Turn the
device over for a ground symbol, and make sure the grey test lead aligns with this symbol.
