Write Permission - MCi iControl User Manual

System Options
• Mode of Operation: The current group operating mode is displayed here:
• Automatic: The group assigns operating modes automatically depending upon build-
ing traffic conditions.
• Balanced: The group is operating in balanced mode, favoring neither up, down, nor
lobby traffic.
• Lobby Peak: The group is operating in lobby peak mode, favoring traffic from the
building lobby or lobbies.
• Demand Up Peak: The group is optimizing car assignment to favor up direction traffic.
• Demand Down Peak: The group is optimizing car assignment to favor down direction
traffic.
• Network Info (LAN and System): The LAN is the ethernet network used by iView, iMon-
itor, and iReport to communicate with groups and cars. The System is the ethernet net-
work used by the group and individual car controls to communicate with one another.
• IP Address: The TCP/IP address of the group on this network
• Subnet Mask: The subnet mask limits the number of valid addresses in the group. For
iControl, this should always be 255.255.255.0
• Gateway LAN: 192.168.191.254
• Gateway System: 000.000.000.000 (o.o.o.o)
• Connection Status: Displays the active car connections.
• Bus Status: For each serial I/O bus (1, 2, 3, 4), displays operational status:
• Connected: Lights green if the bus is connected.
• Bus Voltage: Lights green if the bus voltage levels are adequate.
• Driver VDC: Lights green if the DC voltage provided by the driver is adequate.
• Node Control: The driver polls the nodes (addresses) of connected devices (hall calls,
other I/Os). This LED lights green when all nodes are responding correctly.
• Bus Enabled: Lights green when there is activity on the bus.
• High Current: Lights red if current demand is excessive. Occasional flashing is normal.
Near continuous flashing or steady on state means that the serial driver is unable to
provide enough current to meet demand. Continued high demand can damage the bus
driver. Contact MCE Technical Support.
• Emergency Power:
• Generator 1: Commercial power has been interrupted. Generator 1 is functioning.
• Generator 2: Commercial power has been interrupted. Generator 2 is functioning.
• Write privilege timeout: Allows you to set the amount of time for which write privilege is
granted. The default is 15 minutes. A value of zero = no time out.

Write Permission

When some one working in iView wants to change an iCue setting, they have to request permis-
sion by selecting Acquire from the Write Privileges menu. When they do, a pop-up dialog will
appear on the iCue screen in which you can approve or deny the request. This prevents remote
iView connections from making changes without the permission of machine room personnel.
If you request permission from the iCentral iView PC, immediately switch to the iCue PC by
pressing <scroll lock> twice and approve the request in the pop-up dialog. Then switch back to
the iView PC to make the changes.
