Supported interfaces include RS-232, RS-422, and RS-485, enabling connectivity to single or multi-drop Modbus RTU devices. Channel isolation ensures deterministic communication even under high-noise industrial environments. Cold junction compensation (CJC) is not applicable, but hardware flow control and parity options provide flexible protocol compliance.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How many Modbus devices can be connected in RS-485 mode? A: Up to 15 Modbus RTU-compatible devices can be connected in multi-drop configuration.\u003c\/p\u003e\n\u003cp\u003eQ: What baud rates are supported? A: Configurable baud rates up to 115,200 bps are supported across both channels.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module include internal safety barriers?
