Frequently Asked Questions
Q: What is the difference between the 140CPU31110 and 140CPU31110C?
A: The 140CPU31110C is the conformal-coated version of the 140CPU31110 Unity processor. Its specified protective treatment is Humiseal 1A33. The coating version should be considered when identifying replacement hardware for an existing installation.
Q: Does the 140CPU31110C support Ethernet communication?
A: Ethernet TCP/IP communication is supported through optional communication modules installed in the local Quantum rack. The processor specification lists a capacity of two local Ethernet TCP/IP connections; it should not be confused with an integrated Ethernet port.
Q: What should be checked before replacing the 140CPU31110C?
A: Check the installed rack configuration, Unity application requirements, communication modules, I/O architecture, serial port settings, and battery condition. Also verify the processor firmware and application compatibility before commissioning a replacement.
