Preparing to Install
eMerge System Overview
eMerge is a web-based system that does not require a computer to operate. A
computer is required only for system setup, programming, and monitoring.
eMerge is provided in a controller cabinet containing the following:
• A Mini-ITX Network Controller running the controller application software.
• A SAM-E module providing network connectors and power buttons.
• A Network Node blade running the node application software.
• An access control blade that supports up to two card readers.
You can add up to three additional application extension blades to the
cabinet. For more information, see “Connecting Readers, Inputs, Outputs,
and Temperature Sensors” on page 12.
Note: The cabinet for the supported eMerge expansion node is the same except
that it does not contain a Mini-ITX Network Controller.
Topology Considerations
Issues to consider when selecting a topology for the installation include
simplicity, security, wiring requirements, bandwidth requirements, site distances,
current network topology, and the number of security system resources to be
wired.
The simplest topology, shown in Figure 1, will be the most common case for
small systems. All users and network resources share the same LAN.
