To log up to 8 analog inputs (or 16 with a different cable) you can use the following analog input cable from DigiKey. It is approximately $45 + delivery. Free delivery if you spend over $60.
The driver is already included in the PCMTEC Editor installer so no extra software is needed. They do have a package on their website to test the cable separately to our software if you want which can be downloaded here.
Next plug the cable in and press the DLP button in the datalogging screen to connect to the cable. You can then select the DLP inputs from here:
Next select which of the 8 analog inputs you would like to log here:
To change the description/units type into the Units field.
To modify the voltage lookup table right click and pick "Equation"
You can enter in a new voltage lookup table here to suit your wideband etc.
To wire up your DLP cable you can read the data sheet here or follow our test pictures below.
If you have 1 wideband, simply wire the ground to the ground pin, wire the postive input to pin 1, next loop the rest of the input pins (2,3,4,5,6,7,8) to ground to stop the signals floating. You don't have to do this, but the inputs will likely read 5v if you don't.
If you have 2 widebands, simply do the same and wire the second sensor to pin 2 and remove the ground loop from pin 2.
Test Harness Wiring
This is two potentiometers wired up to emulate 0-5v sensors. We are utilising the +5V pin that is available on the DLP header.
Here we have looped the ground pins on input 5-6-7-8-GND to stop the signals floating.
Here we have wired in "sensors" 1 and 2 into pins 1 and 2. We also looped them to pins 3 and 4 to duplicate the signal.
