all embedded master..I hope you could help me to solve my assignment.. 
)
I got a problem to communicate between autonics (temperature_controller.type) and arduino (uno.type).,
the case is I need to take temperature data from autonics as input, and send it to the PC.
the problem is arduino only had 1 port serial (instead of we make the others with the RX-TX available on it).
the question is:
1.which is better to make ttl-RS485 converter? 75176 or MAX485?? could you give me the scheme please..
2.I need to make it as 'realtime' as possible, arduino acted as slave and master in a same time, could it be make?
3.please share modbus protocol that compatible with Uno..,
Thanks guys, I appreciate your kindness)
