Quick Start Guide
Connecting the
TWR-SER
InserttheTWR-PXR40andTWR-SER
boards into the primary and secondary
elevator board. The “primary” and
“secondary” cards for each module are
indicated along the card edges.
Powering Up the
TWR-PXR40
Connect the TWR-PXR40 board to a
computer or a wall charger using the
provided USB cable. Additionally, the
USB connector on the primary elevator
orOSJTAGconnectorcanbeusedto
power up the board.
Using the Serial
