Can i use a barrier strip for control panel grounds instead....
2PacMan:
Can i use a barrier strip of some sort to wire all of the grounds from my control panel buttons and joysticks instead of daisy chaining them all together? THen can i wire the strip to the IPAC? To me, that seems easier because then if there is a problem with one of the buttons, it will be obvious, instead of having all of the buttons linked.
Another question...if i'm using a ground barrier strip, do i even need to hook it up to the grounds of the ipac if i'm grounding it through the strip.
Then, if this is and OK procedure, where do i mount the grounding strip, somewhere on the wood cab? Do i need to wrap it in electrical tape??
Thanks

Yes, it will work. I think the daisy-chaining method is a better choice, but a barrier strip isn't a problem.

Not sure. I know it will work if you run the switch gnds to the strip and the strip to the I-PAC GND terminals and leave it "floating" so to speak. I don't know if hooking it to some other ground point as well creates problems or not. My gut feeling is that if you did this, you would also want to connect the I-PAC GND terminal to the same gnd point as the barrier strip, i.e. if the strip is grounded to a metal panel in the cab, run the I-PAC GND terminal to the same panel.

Mounting is not very critical (you don't want it hanging and running into hot wiring, but otherwise . . . Electrical tape is not required.

Great...thanks for the input....why would you prefer the daisy chain method? Is it just because there would be less wires to deal with coming from the cp?
Performance wise, it should be the same, right? Seems like the non-daisy chain method would be easier for troubleshooting.

Personal preference really -
Actually, what I prefer is a loop, I-PAC GND to switch 1 to switch 2 etc. and BACK to I-PAC GND.
This requires two breaks in the GND wire before a failure will have ANY effect.

In the TOK encoder thread somebody mentioned P360s not working unless there was a common ground (or something like that). Did I misunderstand taht post or is that true and why is that?
