The 485SD9R is a port-powered two-channel RS-232 to RS-485 converter. It converts TD and RD RS-232 lines to balanced half-duplex RS-485 signals. The unit is powered from the RS-232 data and handshake lines whether the lines are high or low. | RS-232 Side:Connector: DB-9 femaleSignals: Passes through pins 3 (TD) and 2 (RD)Pins 7 (RTS) and 8 (CTS) are tied togetherPins 4 (DTR), 6 (DSR), and 1 (CD) are tied together | RS-485 Side:Connector: DB-9 femaleSignals: 2 wire, half-duplex operation onlyAutomatic control circuit enables driver only when transmittingReceiver is disabled when transmitting to prevent echo back to RS-232 device | Data Rates: Up to 115.2 k baudDistance: Depending on power from port; will transmit up to 4000 feet at 19,200 baudDimensions: 2.50 x 1.30 x .80 in | Power Requirements: No external power is required if two RS-232 output handshake lines are available. If the handshake lines are raised and no termination is used, the power efficiency is greatly increased.
