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?

[Bueller]

The SCXI1314 is a terminal block that is mainly used in conjunction with the SCXI 1520. For a complete description of the SCXI 1314 signal connection, I recommend checking the first page of the manual.

Assuming that you are using the SCXI 1520, the following Knowledge Base describes how you can make torque measurments.

That manual is where i am having difficulty, i dont have it for whatever reason and that link is coming up with an error on page and it will not load. is there anything completely more specific on how to directly wire a transducer into the scxi 1314 so that the 1520 can read it properly. now i can starting to understand that i may have to use more then one terminal to connect this one transducer, because it does have a total of 10 wires that have to be used, two of which is not a remote sense signal. but is it feasible to wire it in such a way that i dont have to jumper connection to a achieve excitement from one terminal to the other so that the transducer will read and output data on the second terminal? i am just really lost on this one and fear the dangers of doing it completely wrong.... any help will be greatly appriecated .

Here's the manual.

It is really helpful and has the description of each pin you need to connect.

Please feel free to ask more questions if you have any.

this manaul is clear and helpful, but this situation that i have is a bit different then just plug in and play. this torque and angle transducers only has 10 wires that connect, it would seem that there are 2 power wires, 2 signal wires, 1 enc gnd wire, 1 +5volts wire,

[bbudziszek]

sorry... to finish... 1 cw lead wire, 1 ccw trail wire, 1 id gnd wire, 1 id data wire. i can see where the torque data comes from and the angle data comes from. but it would seem that i would have to jumper the power wires and the id wires to get the information to travel to labview. but then again i am not at al sure, and am having great trouble finding clearity in this sort of wiring. thank you for your help so far...

Bob,

It look to me there are many wires, and from the description , I can not tell what each wire is for.

Can you please attach a datasheet or a diagram that I can look at.

Faris,

http://www.rstechltd.com/wiring.htm  this site gives the wiring diagrams, the transducer that i have is the one that has wires up to 'K'.

there is also a link to a much clearer wiring diagram page http://www.rstechltd.com/Wire_Diag.PDF . thank you much for your help so far..

Bob,

Your encoder generates a differential signal, so C & D should be connected to S+ and S- of the 1314 respectively.

A & B should be connected to P+ and P- respectively.

If you are using remote sensing ID GND and ID data should be connected to RS+ and RS- respectively, but in your case I doubt that you need to use them

The +5 V and GND should be connected to a 5V suuply and it's Grd.

The pin assignment that you sent me doesn't show wether they are an input or an output and the nature of their signal.

I'm guesing they are a digital output, so they need to be connected to a digital in of the data acquisition device.

Please let me know if you have any further questions.

Faris,

So i should:

A(+ excitation) connects to P+

B(- excitation) connects to P-

C(+ signal) connects to S+

D(- signal) connects to S-

E(encoder Gnd) connects to Ground

F(+5 Volts) connects to 5 volt supply

G( CW Lead) connects

H(CCW Trail) connects

J(ID Gnd) connects to RS+ or RS-

K(ID Data) connects to RS+ or RS-

what should i do with the counter clockwise trail and clockwise lead? or should i disregard them?
