Digital Sidecar Resistor

Hi,
I know that when adding digital inputs to the Driver Station, one must utilize pull-up or pull-down resistors. Are they also required for the digital inputs on the Digital Sidecar? (or are they integrated?)
Thanks,
Nick

Re: Digital Sidecar Resistor

According to the schematics the inputs/outputs on the sidecar have 10K pullups.

What schematic? Where did I miss that? Can you provide a link or reference?

It's not a schematic, but Chapter 3 Component Data Sheets of the Control System Manual describes the 10k pullup resistors in section 3.5.3 on page 30.
