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.

From the 2009 FIRST Robotics Competition Manual and Related Documents page, follow the link for Additional Technical Resources for the schematics.
