Description Our RS232 to RS485 / RS422 adapters are ideal for connecting devices which use RS485 or RS422 to an RS232 port. They are available in non-isolated and isolated models. On the isolated model, the isolation circuit provides an optical barrier between the RS232 and RS422/485 bus connected to the unit, helping to isolate harmful spikes and surges which may occur on the bus. The isolated models also features built-in surge protectors to further protect against spikes, surges and electrostatic discharge. A set of DIP switches allows selection of RS422, RS485 full-duplex or RS485 half-duplex on the RS422/485 side. Internal termination and bias resistors can be enabled via internal jumpers. The unit features automatic transmit-enable for RS485 which avoids the need to do this via manual control of RTS. In RS422 mode the transmitter is always on. This unit uses a universal switch mode PSU (supplied) and unlike many inferior products does not rely on borrowing power from signal lines
