Which jumper to open on AS7265x spectrometer?

Hi,

I’d like to communicate with the AS7265x via its serial interface. To do so, I2C needs to be disabled. According to the hookup guide,

“The I2C jumper on the front of the board must be opened to remove the pull-up resistors from the TX and RX lines”.

However, the highlighted image shows three pads, and two connections. Are both of these connections to be severed, or just one?

Thanks for any information.

There are two pullup resistors, so open both connections. Check the schematic below.
