EVM430-FR6043: Using 5V TX in Water Mode

Part Number: EVM430-FR6043
Other Parts Discussed in Thread: TIDM-02005,

Hello,

my question is: Is there a Possibility to use the 5V TX of the EVM430FR6043 in Water Mode? 

I'm currently using the EVM430FR6043 with the Water Demo Code. I connected all Jumpers as described in Design Guide: TIDM-02005 Optimized Ultrasonic Sensing Metrology Reference Design for Water Flow Measurement. Now I found, that it is generally possible to drive the Transducers with 5V instead of 3V3, changing Jumpers on the Board. Unfortunately these are Jumpers, I should not use referring to the Design Guide for Water Metering. So is there still a way to set the Jumpers / connect the Transducers using 5V in Water mode?

 

Thanks in advance!
