I don't read R67B that way, necessarily, though I do see how you could draw that conclusion.

B. PWM configuration: If the Jaguar motor controller is controlled via PWM communications, the PWM port on the Jaguar motor controller must be connected directly to a PWM port on the Digital Sidecar with a PWM cable.

Translation: Jaguar connected to PWM port--theoretically, using the Y-cable would be legal here, especially if the other end of the Y wasn't connected.

No other device may be connected to these PWM ports.

Can't connect anything else--including another Jaguar that's powering a motor in the same gearbox? That's a ruling that would be pretty dumb, at least on the surface. I can see not having a Victor or Talon on the Jag ports, but not having two Jags? Also, having the Talons and Victors allowed to Y-cable but not the Jags doesn't make sense.

I'd say to ask Q&A whether R67B prohibits connecting Jags to the same PWM port via Y-cable, and if it does, what the reasoning is behind that, given that R66 seems to allow Talons, Victors, and Spikes to share PWM ports via Y-cable.


Of course, if you wanted to use CAN capability, you'd have no trouble connecting all the Jags you wanted in line...
