Note: The adapter requires a 9 to 24V DC power which means it can be powered by the same 12 to 24V power supply of the PLC.

This RS232-to-RS485 converter supports both RTS-controlled turnaround and automatic turnaround of the transceiver buffer. The following are some possible applications:
- For programming an M-series PLC via its RS485 port so that its RS232 port can be freed for connecting to other devices such as HMI, SCADA, barcode scanner, smart card readers, etc.
- For linking as many as 240 PLCs via RS485 multi-drop bus to a single PC for local programming or remote programming / monitoring via the Internet.
- To transparently convert the PLC's RS485 port into an additional RS232 port for interfacing to third party RS232 devices. This is made possible by auto-turnaround features built into the adapter.
