What’s so hot about Send Data Control (SDC)?
As operating systems become more complex, it is increasingly difficult
to control an RS-485 driver with standard software and the RTS line.
This is especially true in Windows and multi-tasking operating systems.
With B&B’s Automatic Send Data Control circuit, driver control is in the
converter hardware, so you don’t have to work with software at all. The
circuit monitors data flow and enables the driver during transmission
and automatically disables it when no data is being sent. There is no
need to rework software or install new drivers.
Most B&B Electronics RS-232 to RS-485 converters and RS-485 serial
cards include Automatic Send Data Control.
