Pressure Sensors Creation
Pressure Sensor Connector
- Strip the cable housing back long enough that the housing is flush with the bottom of the pin but does not get crimped with the wire.
- Use the appropriate pin-crimping tool for the given size of pin.
- Identify orientation of the DSUB shell and the needed channels.
- Push DSUB contact all the way into DSUB shell.
- crimp the contact tighter with flat pliers if the pin does not easily push into the shell.

DAQ header DSUB9 1 GND, do not connect 2 +15V, brown 4 green 3 signal, red 9 white 4 signal return, do not connect NOTE: This device requires DAQ signal conditioning circuit with: 0R series, 82R parallel (sampling resistor), 0R from signal return to GND. DAQ input voltage should be 0.328 V to 1.640 V nominal.

DAQ header flying lead 1 GND, do not connect 2 +15V, brown green 3 signal, red white 4 signal return, do not connect NOTE: Do not connect anything to red and black sensor conductors. NOTE: This device requires DAQ signal conditioning circuit with: 0R series, 82R parallel (sampling resistor), 0R from signal return to GND. DAQ input voltage should be 0.328 V to 1.640 V nominal.
MKS 870B Micro-Baratron Pressure Transducer (4-20 mA “Current Unit”) Model code L (10-ft cable)

MKS 901P, 910 DS, 925(?)
DAQ header DSUB15 1 GND, black 4 2 +15V, brown 3 3 signal, red 5 4 signal return, orange 6
signal return must have a high resistance (>= 100R) to GND, otherwise half the power return current will flow through the signal return line

DAQ header DE9F 1 GND, black 9 2 +15V, brown 4 3 signal, red 1 4 signal return, orange 8
Devices with RJ45 interface connectors
Use a short adapter cable with the T568B wiring convention on the RJ45 end to route the signals to the Aeon wiring convention on the Molex end. I.e., the adapter wire colors are determined by the T568B wiring convention, whereas those in the cable from the adapter to the DAQ are determined by Aeon's signal-based wiring conventions.
