CAN resistors

Post by ngustavson » Tue May 15, 2012 7:40 am

I can't find any information on internal CAN termination resistors for the PV750.
Does it have them? I was thinking they used to be configurable but I don't see anything in the current configurators.

Hello ngustavson,

The PV750 does have internal terminator resistors.

To enable/disable them you change the value in a variable.
CANPort1.Resistor ( 0 = disabled, 1 = enabled )
CANPort2.Resistor ( 0 = disabled, 1 = enabled )
The PowerVision Studio 2.3 Applications Reference document talks about them.

In the Murphy Standard Configuration (PV750) 2.3 you can change their value from the hidden system settings menu.

Regards,
