When configured as a Master, it can poll multiple slave devices on a multi-drop network. In Slave mode, the module presents its assigned I\/O points to a remote Master controller. Engineers should ensure that proper termination resistors (120 Ohm) are applied at both physical ends of the RS-485 daisy chain to prevent signal reflection and data corruption.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFunctional Comparison: IC693BEM321 vs. IC693BEM320\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eWhile both modules share the same physical footprint, their capabilities differ significantly:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIC693BEM321\u003c\/strong\u003e: Supports both Master and Slave roles.
