Where are UART pins on sbRIO-9627?

[aan928]

I'm new to SingleBoard RIO and I need 5 UARTS but I can't find the RX TX pins. Where are the pins located?

Product page: https://www.ni.com/en/shop/compactrio/single-board-rio.html

RS232
Onboard (Total) = 2 (6)

Page 42 of the user manual starts to document how to expose the additional UARTS.

https://www.ni.com/docs/en-US/bundle/sbrio-9627-feature/page/overview.html

Those UARTS are implemented in the FPGA, so the TX and RX pins can be routed to any of the FPGA DIO lines. That is defined via the sbRIO CLIP generator tool installed with LabVIEW and implemented by selected a socketed CLIP RMC plug-in in the LabVIEW project.

Page 24 of the RMC design guide also gives further detail:

Also, this NIWeek presentation walks through the RMC design process and SW tools for configuring additional peripherals, such as UARTS.

Thank you.

1. So I should be able to have 6 UARTS on these GPIO pins?

2. Is it possible to configure more than (6*2) GPIO pins to have UART functionality?
