High active RTS in RS485 mode

Hi,
I have installed the most recent demo image via TEZI and did some measurements using a Ixora carrier board. Please find my results and the test program attached. The “low active RTS” looks fine i guess (-6V means logic high). However the “high active RTS” looks odd. Can you confirm that this is the expected behavior?

"low active RTS"
"high active RTS"
