About this product
Bidirectional converter between RS-232 and RS-485 that changes the TXD and RXD signals of an RS-232 serial port into a 2-wire half-duplex RS-485 signal. It links a main controller with peripherals or other controllers over point-to-point or multi-device networks, and is used in industrial automation, access control and parking systems. According to the listing, it needs no separate power connection.

Frequently asked questions
How do I wire the converter?
Connect the RS-232 side's TXD, RXD and GND to your PC or controller serial port, and connect the RS-485 side's A and B lines to the bus. Keep the wiring polarity consistent across all devices on the bus.
Is it full duplex or half duplex?
The RS-485 side is 2-wire half duplex, so devices on the bus take turns transmitting. The listing describes a request-response communication scheme for this reason.
