Personal Area Network (PAN)
In mesh ZigBee networks, a PAN is a data communication network that includes a Coordinator
and one or more routers/end devices. Network formation is governed by Network Maximum
Depth, Maximum Child Routers and Maximum Children End Devices.
PEAP
See Protected Extensible Authentication Protocol.
port forwarding
A serial port configuration that sends data directly to a specific port instead of the path
determined by the router based on traffic.
Power-On Self Test (POST)
When power is turned on, POST (Power-On Self-Test) is the diagnostic testing sequence that a
computer's basic input/output system (or “starting program”) runs to determine if the computer
keyboard, random access memory, disk drives, and other hardware are working correctly. If the
necessary hardware is detected and found to be operating properly, the computer begins to boot.
If the hardware is not detected or is found not to be operating properly, the BIOS issues an error
message which may be text on the display screen and/or a series of coded beeps, depending on
the nature of the problem.
Protected Extensible Authentication Protocol (PEAP)
A protocol proposed for securely transporting authentication data, including passwords, over
802.11 wireless networks. PEAP makes it possible to authenticate wireless LAN clients without
requiring them to have certificates, simplifying the architecture of secure wireless LANs.
provisioning
The process of configuring a mobile (cellular) device with the required configuration used to
access the mobile network.
RealPort
Patented Digi software for COM port redirection. RealPort makes it possible to establish a
connection between the host and networked serial devices by creating a local COM or TTY port
on the host.
The COM/TTY port appears and behaves as a local port to the PC or
server.
This process of COM port redirection allows existing software applications like DNP3
and Modbus to work without modification. Unlike other COM port redirectors, RealPort offers
full hardware and software flow control, as well as tunable latency and throughput. These
features ensure optimum performance, since data transfer is adjusted according to specific
application requirements.
remote login (rlogin)
A remote login to a Digi device’s command-line interface (CLI). rlogin is a Unix command that
allows an authorized user to login to other UNIX machines (hosts) on a network and to interact
as if the user were physically at the host computer. Once logged in to the host, the user can do
anything that the host has given permission for, such as read, edit, or delete files.
remote shell (rsh)
A Berkeley Unix networking command to execute a given command on a remote host, passing
it input and receiving its output. Rsh communicates with a daemon on the remote host.
