connecting RS technology torque convertor to the wiring board of a ni scxi 1314, whats the best way considering that this reads botht the input torque vs. time as well as the input torque vs. angle?

it wasn't clear from the pinout that you sent me if the CCW and CW generate a signal or are used to control something in the encoder.

If they generated signa, they sgould be connected to the signal in. If they are used to control the encoder, they need to be connectted to a voltage source.

so then i take it that the remaining questionable wires to be connect is used to control a driver tool throughout the program. For instance if i was running a program that required a driver tool to tighten to a specific torque and then reverse and loosen to a lesser torque then the encoder ground, +5 volts, cw & cww, and remote signal wires would be what i would have to connect to that specific driver tool control module that has its own power source. is it possible that i could use the scxi 1314 through the scxi 1520 with labview to create a program that reads the data from the transducer and then uses the remote wires to control the driver? if so what manual would help me to design and set up such a program with a driver, and would i need another component to run the driver other then the scxi 1314/1520?

You can definitely do that in LabVIEW. However. the 1520 is an input module. You need an output module to generate the control signal.

Check the following link for the different available SCXI output modules.

You might also be able to the use the output ports of the DAQ device that you paired with the SCXI chassis, by usinf the SCXI 1180 feed through module.

thanks that makes a little more sense then trying to run an 'out' on an 'in'. another question about the wiring. calibration? whats the best way the set up the jumper wires. the wiring diagram show a one way but i beleive i need to acheive 350ohms does it matter which of the four possible connection i use?

Hi Bob,

If you are referring in your question to the 1520 please check pages 35 - 38 of the SCXI-1520 manual.

HI Faris,

no i hate to say it but i was refering to the 1314.

The 1314 is just a terminal bolck where you can add resistors on. For the different connection, you still need chapter 2 of the 1520.

However, I need to mention that the quarter bridge- completion resistor has a factory default value of 350 ohm.

Faris,

         sorry about the next three blank messages, enter button got stuck. Now forgive my ignorance but the wiring setup in chapter two is this just as an addition to the way we set i up originally or am i to use this setup instead of the one previously?
