Firmware
The programming code that runs a networking device.
Fragmentation
Breaking a packet into smaller units when transmitting over a network medium
that cannot support the original size of the packet.
FTP
(File Transfer Protocol) - A protocol used to transfer files over a TCP/IP net-
work.
Gateway
A device that interconnects networks with different, incompatible communica-
tions protocols.
HDX
Half Duplex. Data transmission that can occur in two directions over a single
line, using separate Tx and Rx frequencies, but only one direction at a time.
HiPR-900™
Frequency hopping spread spectrum wireless modem that operates in the license
free 902-928 MHz band.
HTTP
(HyperText Transport Protocol) - The communications protocol used to connect
to servers on the World Wide Web.
IPCONFIG
A Windows 2000 and XP utility that displays the IP address for a particular net-
working device.
IPSec
(Internet Protocol Security) - A VPN protocol used to implement secure ex-
change of packets at the IP layer.
LNK LED
Ethernet connection established.
MAC
(Media Access Control) Address - The unique address that a manufacturer as-
signs to each networking device.
NAT
(Network Address Translation) - NAT technology translates IP addresses of a lo-
cal area network to a different IP address for the Internet.
Network
A series of computers or devices connected for the purpose of data sharing, stor-
age, and/or transmission between users.
Network speed
This is the
bit rate
on the RF link between units. Could be different from COM
port
baud rate.
Node
A network junction or connection point, typically a computer or work station.
OIP
Optimized IP – Compresses TCP and UDP headers, and filters unnecessary ac-
knowledgments. This makes the most use of the available bandwidth.
OTA
Over-The-Air - Standard for the transmission and reception of application-related
information in a wireless communications system
PD
PD = PARALLEL DECODE ™ technology
Ping
(Packet INternet Groper) - An Internet utility used to determine whether a par-
ticular IP address is online.
PLC
Programmable Logic Controller. An user-provided intelligent device that can
make decisions, gather and report information, and control other devices.
PoE
Power Over Internet. Technology that allows the electrical current, necessary for
the operation of each device, to be carried by the wired Ethernet LANs data ca-
bles rather than by power cords.
PPTP
(Point-to-Point Tunneling Protocol) - A VPN protocol that allows the Point to
Point Protocol (PPP) to be tunneled through an IP network. This protocol is also
used as a type of broadband connection in Europe.
PWR LED
Indicates presence of PoE or DC power input.
Router
A networking device that connects multiple networks together.
RS-232
Industry–standard interface for data transfer.
