Multi-Master RS-485 Systems
Each node in a multi-master type RS-485 system can initiate its own
transmission creating the potential for data collisions. This type system
requires the designer to implement a more sophisticated method of error
detection, including methods such as line contention detection,
acknowledgement of transmissions and a system for resending corrupted data.
Systems with Port Powered Converters
RS-232 to RS-422 or RS-485 converters that derive their power from the
RS-232 port are becoming more common in data systems. A good
programming practice is to set unused handshake outputs to a high voltage
state in systems using any type of RS-232 to RS-422 or RS-485 converter. This
will assure the best possible operating conditions for all converters used.
