iControl Ethernet Overview
iControl uses two distinct Ethernet networks:
• The System switch connects the iCentral SYSTEM NIC to other MCE equipment like the
elevator controllers, Serial Hall Call systems, and input/output expansion boards (SC-ION
boards). iCue controls dispatching through this network.
• The LAN switch connects the iCentral LAN NIC used by iView to configure both iCentral
and iControls. Through the LAN hub/switch, the elevator group may also be connected to
an external network or building LAN.
