Figure 5.4 Comm-Connect Interconnection
For systems that use the Local/Dispatcher option, the Comm-Connect Cabinet is where the
serial and Ethernet communication equipment is housed and where the connections are made.
• Ethernet Switches: The Ethernet switches are the main connection / distribution point for
the Local Area Network (LAN) and System Ethernet networks.
• SC-HC-ME Serial to Ethernet Adapter: This component converts the serial signals from
the SC-HCDA Serial Hall Call Driver Assembly to the Ethernet protocol for transmission
on the System Ethernet network.
• SC-HCDA Serial Hall Call Driver Assembly: This assembly provides power and communi-
cation to the Serial Hall Call Node boards located in each hall fixture box. Power and com-
munication is transmitted on the two wire Serial Bus. Two SC-HCDA assemblies may be
housed in the Comm-connect cabinet. For more information about the Serial Hall Call
option see “Serial Hall Call” on page 5-17.
• SC-ION Serial Control I/O Board: This board is used for serial communication of signals
other than hall call signal (see “Checking Serial to IP Connections” on page 5-22).
