This transmitter module mounts directly to the left-hand side of a CX20xx CPU block, converting standard internal USB lines into a serialized differential signal suitable for long-distance runs over standard Ethernet-style physical media. This setup is specifically optimized for connecting control panels such as the CP29xx-0000 series without signal degradation or latency spikes, ensuring seamless peripheral integration in complex industrial environments.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
