Hello guys.
To improve power consumption on a battery powered system, I am planning to remove the termination resistor on a RS485 bus.
It will carry point to point communications (just two transceivers attached to the bus) at low baud rate and through a short cable (2 meters long).
I am using LTC2852 transceiver but I am not sure if its failsafe feature will ensure a receiver known state when the bus is not driven and unterminated. The datasheet does not say anything about internal bias resistors so...
Should I add biasing resistors or it is not needed in this case?
Thanks
