RTS and Auto Transceiver Control
In RS485 communications the driver must be enabled and disabled as needed, allowing all
cards to share a two wire cable. This card provides automatic control, where the driver is
enabled when data is ready to be transmitted. The driver remains enabled for the transmission
time of one additional character after data transfer is complete and then is disabled. The cards
automatically adjust their timing to the baud rate of the data.
The receiver is also normally disabled during RS485 transmissions.
CE Mark
If your card is CE-marked, it meets the requirements of EN50081-1:1992 (Emissions),
EN50082-1:1992 (Immunity), and EN60950:1992 (Safety).
