Hi,

I have an 4 - Wire Master and 2 Wire - Slave. The Connections look like the picture.
With a PC over the serial card, i monitoring(HTerm) the Bus. The Master sending the Request and the slave replies correctly, but in the RBUF is the message what the master has sent. There is, i cant receive the response from Slave, on my Hexagon Kit.I think i could solve this Problem, if the Transceiver would have a Driver Enable.

Maybe someone has an idea for me ?

I hope I could express my problem. 🙂
