Epson Wireless Projector Web Glossary

802.11g/a — High-speed wireless standard that allows users to transmit data at rates of up to 54 Mbps. Operates at either 2.4GHz frequency band or 5GHz, 802.11g is compatible with 802.11b, so it can be used with legacy networks and network devices. Epson wireless projectors include an 802.11b/g/a wireless network card or module for the best in wireless performance and wireless connections speeds of up to 54 Mbps.

Access Point or Wireless Access Point (WAP) — A device which allows computers, projectors and other electronic devices with wireless networking cards to connect to a Wireless Local Area Network (WLAN) and each other. A wireless access point is often connected to a router or hub through an Ethernet (hardwired) connection. In Wireless Infrastructure Mode, Epson wireless projectors connect to a WLAN through a wireless access point.

Ad Hoc (or Peer-to-Peer) — A wireless connection method where the computer and projector communicate directly with each other, without needing cables or access points to connect (see diagram). Quick Connect Mode on the PowerLite 1705c and PowerLite 1715c is an Ad Hoc connection method that simplifies connectivity.


Epson EasyManagement Technology — A proprietary Epson technology found on select Epson wireless projectors that allows you to manage/monitor lamp hours and power-on status, and view and control input sources remotely through either an RJ45 Ethernet port connection or through an added PCMCIA LAN card or module. Email notices alert administrators for various conditions, allowing pages to be sent for immediate troubleshooting.

Epson EasyMP Technology — A proprietary Epson technology found on all Epson wireless projectors that include a PCMCIA slot to accommodate an Epson 802.11b/g wireless card (included with projector) or Epson 802.11b/g/a wireless module (included with projector) to connect wirelessly to the projector from a computer; a third party wired PCMCIA LAN card or Epson LAN module to connect the projector to a LAN infrastructure. Additionally the PCMCIA card can be inserted for PC-free presentations to run presentation directly from your projector.

Ethernet — The most widely installed Local Area Network (LAN) technology. It is also the most common type of cabling used in LANs.

Frame Rate — The number of frames of video or animation that can be transmitted to a wireless projector, denoted in frames-per-second (fps). The faster the frame rate, the faster and smoother the video, animation and transitions between presentation slides will be. Epson wireless projectors use the 802.11b/g/a wireless protocol and a unique algorithm that delivers high-speed frame rates of up to 30 frames per second.

IP Address — An IP address uniquely identifies a single device on a computer network. It's like a street address or telephone number. Epson EasyMP technology allows you to control an Epson wireless projector's menu and settings by accessing its IP address through a web browser. This is known as IP access. Examples of IP addresses include 208.152.64.40 that points to web name such as: USA.ILLINOIS.Chicago.10WackerDr.

Local Area Network — A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a Wide-Area Network (WAN). Most LANs are Ethernet networks.

Mbps — Stands for millions of bits per second or megabits per second and is a measurment of data transfer speed. Epson wireless projectors with 802.11g/a can transmit data at up to 54 Mbps, the current maximum official wireless transfer speed.

NS Connection — A proprietary Epson technology, this software utility allows for fast, easy wireless connections. In Quick Connect Mode, NS Connection automatically seeks and connects to the wireless projector. In Advanced Connect Mode, NS Connection automatically seeks out all projectors (wired or wireless) on you network and lets you select the projector you want to use.

PCMCIA — An acronym for Personal Computer Memory Card International Association and pronounced as separate letters, PCMCIA is a non-profit trade association and standards body consisting of some 500 companies. PCMCIA has developed a standard for small, credit card-sized devices, called PC cards, that are often used in notebook computers, PDA's and projectors to add features such as storage devices, additional memory, wireless LAN and wired (Ethernet) LAN connectivity, and other peripheral devices.

PCMCIA Card — Also know as Portable Computer Cards (PC cards), PCMCIA cards are interchangeable peripherals originally designed for insertion into portable computers in order to enable extra hardware functions. Today many types of devices can use PCMCIA cards. Certain Epson wireless projectors include an 802.11b/g PCMCIA wireless networking card that enables them to transmit data wirelessly.

PCMCIA LAN Card — A plug in card that allows you connect select Epson wireless projectors to an Ethernet network via an Ethernet cable. An optional LAN card is required to set up projectors in the Wired Infrastructure Mode.

PCMCIA Slot — The slot on certain Epson projectors that allows them to accepts PCMCIA cards. These slots can accept both 802.11b/g wireless cards for wireless connectivity as well as LAN cards, which allow for connection to Ethernet networks.


RJ45 — The physical connector that connects a computer or peripheral device directly onto an Ethernet network. Select Epson networkable projectors feature an RJ45 jack that allows them to connect to an Ethernet network via an Ethernet cable (see diagram). This type of connection is used in a Wired LAN at 100 Mbs.


Wireless Local Area Network — Also known as WLAN, or wireless Ethernet, a network that links computers, projectors, printers and other network devices using radio "transceivers" (combination transmitters/receivers) instead of wires (cables).

Wireless Networking Card — A plug-in card that allows computers, projectors and other devices to connect wirelessly to a Wireless Local Area Network. Select Epson wireless projectors include an 802.11b/g wireless networking card or 802.11b/g/a module.
