See IP filtering.
ADDP
See Advanced Device Discovery Protocol.
Address Resolution Protocol (ARP)
A protocol for mapping an Internet Protocol address (IP address) to a physical machine
address that is recognized in the local network.
Advanced Digi Discovery Protocol (ADDP)
A protocol that runs on any operating system capable of sending multicast IP packets
on a network. ADDP allows the system to identify all ADDP-enabled Digi devices
attached to a network by sending out a multicast packet. The Digi devices respond to
the multicast packet and identify themselves to the client sending the multicast.
alarms
In Digi Connect devices, alarms are used to send emails or issue SNMP traps when
certain device events occur. These events include certain data patterns being detected
in the data stream, and cellular alarms for signal strength and amount of cellular traffic
for a given period of time.
ARP
See Address Resolution Protocol.
autoconnection
A network connection initiated from a Digi device that is based on timing, serial
activity, or serial modem signals.
Auto-IP
A standard protocol that automatically assigns an IP address from a reserved pool of
standard Auto-IP addresses to the computer on which it is installed. The device is set to
obtain its IP address automatically from a Dynamic Host Configuration Protocol
