The RS-232 to RS-485 Adapter (IC200ACC415) connects a VersaMax Nano PLC or VersaMax Micro PLC to an RS-485 communications bus. It supports RS-485 multi-drop connections. In conjunction with an RJ45 to DB9 Female cable (IC200CBL500), the adapter converts from the RS-232 (9-pin D-sub male) connector on the Nano/Micro PLC to an RS-485 (15-pin D-sub female) connector. Two LEDs on the adapter indicate activity on the transmit and receive lines. Power for this adapter is provided by the Micro/Nano PLC.
