System TCP/IP
iCue uses the System TCP/IP bus to communicate with other MCE components, including:
• SC-ION I/O: SC-ION boards provide field inputs and outputs for iCue. Customers may use
these inputs and outputs for a variety of purposes. Typically, an input might be used to
detect a switch closure while an associated output might drive an indicator lamp for the
switch. Normally, one or two SC-ION boards, each providing 16 inputs and 16 outputs are
used. If I/O demands are greater, more may be used. SC-ION boards are connected to the
iCue system bus.
• Serial Hall Call: MCE Serial Hall Call greatly reduces the amount of hall call wiring typical
of most elevator installations. The MCE Serial Hall Call bus is a simple, twisted-pair of
16AWG wires along which as many as 980 device addresses may be supported. Power and
communication are both delivered by the serial bus. If current requirements are high, as
many as four serial hall call drivers may be used to support the bus.
• Serial Driver: The current demands of the serial bus may be significant if many devices are
simultaneously active. To meet these demands, each bus leg has its own Serial Driver.
• Serial to TCP/IP: The Serial Driver communicates with hall call nodes and ION boards
over the two-wire serial bus. The serial output of the Driver is converted to TCP/IP (Ether-
net) and routed through the System hub/switch to the iCue PC. TCP/IP from the iCue PC
is likewise routed through the System hub/switch and then converted to serial data for the
Driver.
• System Hub/Switch: The System hub/switch is a standard Ethernet hub. The hub routes
data so that TCP/IP communications between connected devices are correctly connected.
• iControls: Each car in the group is under the primary direction of its own iBox/iControl.
iCue communicates with all the iControls in its group through the System TCP/IP bus.
LAN TCP/IP
The LAN hub/switch allows local and remote personal computers running iView software to
connect to iCue and all group iControls. The iView application is a user-friendly, graphical user
interface that allows you to easily configure iCue and all the individual iControls in the group.
