- 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.
