(DHCP) server. But if the DHCP server is unavailable or nonexistent, Auto-IP will
assign the device an IP. If DHCP is enabled or responds later or you use ADDP, both
will override the Auto-IP address previously assigned. Also referred to as Auto-IP.
CDMA
CDMA (Code-Division Multiple Access) protocols are used in wireless
communications. CDMA is a form of multiplexing, which allows numerous signals to
occupy a single transmission channel, optimizing the use of available bandwidth. The
technology is used in ultra-high-frequency (UHF) cellular telephone systems in the
800-MHz and 1.9-GHZ bands and through an analog-to digital conversion enhances
privacy and makes cloning difficult.
CLI
Command-line interface.
COM port redirection
The process of establishing a connection between the host and networked serial devices
by creating a local COM or TTY port on the host. See also RealPort.
configuration management
For Digi devices, configuration management involves managing the files and settings
that contain device configuration information. Configuration management tasks include
copying device configuration files to and from a remote host, upgrading device
firmware, and resetting the device configuration to factory defaults.
coordinator
In Mesh/ZigBee networks, a coordinator is node that has the unique function of forming
a network. The coordinator is responsible for establishing the operating channel and
PAN ID for an entire network. Once established, the coordinator can form a network by
allowing routers and end devices to join to it. Once the network is formed, the
coordinator functions like a router (it can participate in routing packets and be a source
or destination for data packets). Characteristics of coordinators include:
– One Coordinator per PAN
– Establishes/Organizes PAN
– Can route data packets to/from other nodes
– Can be a data packet source and destination
– Mains-powered
In the web interface, a coordinator is also referred to as a gateway device.
