Applications
KVM switches like the Raritan MC4E were widely used in data centers, server rooms, and multi-workstation environments throughout the 1990s and into the 2000s to reduce hardware overhead — allowing one operator console to manage multiple machines without a dedicated monitor and keyboard at each station. The MC4E's dual monitor output (VGA and TTL) made it particularly suited for mixed environments combining newer VGA-based PCs with older TTL-monitor workstations or terminals, a common situation during the transition period away from character-based systems. The auto-scan feature let administrators cycle through connected machines automatically to monitor activity without manual switching. Raritan Computer Inc. was a well-regarded manufacturer of KVM switching products during this era, and the MC4E represents their entry-level master console line. Units like this remain useful today for anyone maintaining legacy systems that use VGA or TTL video, or for lab and test bench setups where a single console needs to switch between several machines.
This Raritan Computer Inc. RCI MC4E Master Console 4-Port KVM Switch has been inspected and appears to be in good used condition. The front panel buttons and LED indicators are intact. The rear connectors — including the VGA monitor port, TTL monitor port, keyboard port, and four 25-pin keyboard/monitor channel ports — show no visible damage. The chassis has light surface wear consistent with prior use. It has not been powered up or tested at our facility but came out of a working environment.
