- Converts RS-232 to 4-wire RS-422 or to 2- or 4-wire RS-485.
- Bidirectional data conversion.
- Enables you to select RS-485 2-wire half-duplex or RS-485 4-wire full-duplex operation.
Selectable RS-422 operation with transmit and receive always enabled.
Set operating mode with four switches.
Automatic RS-485 driver control, so it works without any special programming for handshaking signals. Also enables transmitter from RS-232 TD signal and receiver when not transmitting.
Built-in bridging switches for 2- or 4-wire operation with no external jumpers to set.
Converts using either port power or power from an external 12-VDC power supply (not included). No external power is required if two RS-232 output handshake lines are available.
