Its Ethernet 10\/100Base‑T port and RS‑485 interface maintain stable propagation intervals for protection‑signal exchange. I\/O density scaling is achieved through modular UR frame configuration, while firmware flash compatibility spans versions 4.8 through 6.0x. The CPU module itself contains fixed hardware characteristics and does not perform programmable logic beyond relay‑application execution.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the UR‑9KH differ from earlier CPU modules?\u003c\/strong\u003e A: The 9K revision includes an added 10\/100Base‑T Ethernet port (RJ‑45), improving communication flexibility while retaining the RS‑485 secondary port.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Must CT\/VT modules match the CPU module revision?\u003c\/strong\u003e A: Yes.
