Stepping up to Wireless Let B B help make the transition to Industrial Wireless Communications

Thinking back, it has not always been possible, practical, or cost effective to run network cables to every device, sensor or roving unit on the factory floor. Today s wireless technologies can eliminate physical and cost barriers, offering a new world of remote communication solutions. Reliable, on-demand communication with control and monitoring down to the individual embedded machine-level sensor is becoming possible with wireless. desktop computers

As wireless network equipment emerges, interest in the use of wireless within industrial environments has surged. But navigating and understanding the technical aspects of the various technologies and standards is essential in the selection of suitable wireless equipment for your application. think pad

Selecting the right technology and equipment will ultimately lead to a successfully installed, well-designed, reliable and efficient communication system. The following diagram and chart offers insight into the different wireless standards and applications best suited for each of the new Wireless Personal Area Networks (WPAN), Local Area (WLAN) and Metropolitan Area (WMAN) Networks applications. These include wireless standards and acronyms such as: 802.15.4 and ZigBee, 802.1a and Bluetooth, WUSB, Proprietary Radio Modems, 802.11 and Wi-Fi and finally 802.16 and WiMAX. repair

MaxStream Proprietary RF 900MHz 2.4GHz Wireless Radio Modems for Long (up to 40 miles!) and Short Range Communications View Complete Model Number Listing

Packaged (Stand alone) Radio Development Kit OEM (module) Radio NEMA Packaged Radio Overview Some data communications applications defy cabling. Whether youre facing long distances, impossible cable routing, or frequent re-location of devices, the simplicity, functionality, and reliable of these wireless solutions is the answer. These radio modems are easy to install and transparent to use. desktop

Need to reach up to 40 miles The new 9Xtend series of 900MHz stand-alone RF modems provides outstanding range in low cost wireless radio modems. They are RS-232/422/485 compatible. Models are available in an anodized aluminum case, a weatherproof NEMA case, or as a board component for inclusion in your product. This affordable RF modem outperforms others for hundreds of dollars less. infosys

These modems feature market-leading receiver sensitivity down to -110dBm (market average is -93 dBm). The FCC restricts the power of all radio modems output, so it is receiver sensitivity that governs how well a radio modem system works. This range, and reliability, offered at a lower price set these modems apart from their competition. refurbished laptops

1. A communications terminal program may depend on the remote terminal to echo the characters typed locally. If the program displays the typed characters, and they are echoed by the remote device, each character is repeated (shown twice - sshhoowwnn ttwwiiccee). The Echo off setting turns off local echo so only the returned characters are displayed. The reverse case is that the remote terminal does not return typed characters, and the user can t see what he/she is typing. Then echo needs to be set on locally. averatec

Echo On

- hardware

1. In a half duplex 2-wire 485 system, the receiver is normally disabled during transmit, so the data is not echoed back to the receiver even though the receiver inputs are connected to the transmitter outputs. A Echo On switch or jumper (if provided) can set the receiver mode so that it is enabled all the time, and transmitted data is returned to the receiver. Echo on can be used in 2-wire mode, but since the setting enables the receiver all the time, this setting is typically used in 4-wire RS-485 and RS-422 modes. dual xeon

2. A communications terminal program may depend on the remote terminal to echo the characters typed locally. If the program does not receive the characters back, the user does not know what is being typed. The Echo On setting turns on local echo so that typed characters can be viewed. displays the typed characters, and they are echoed by the remote device, each character is repeated. If typed characters are repeated twice for each character typed, local echo needs to be set Off. storage

ECP

- Variously called, Enhanced Communications Port, Enhanced Capabilities Port, Extended Capabilities Port. seagate

1. An asynchronous, 8-bitfide parallel channel defined by IEEE 1284 944 that provides PC-to-peripheral and peripheral-to-PC data transfers. computer sales

2. A parallel port standard that provides for automatic background transfer using a computer DMA channel, IRQ and additional input and output port registers. Using DMA transfer under Windows 95/98 can be very fast since once a document is spooled and the header is passed to the DMA circuit, the DMA transfers large blocks of data (350KB per second typical) no matter what else the processor is doing under windows. Other ECP functions are available with some devices if they use Microsoft s ECP standard. ECP mode is available when built-in to the motherboard, or from a ISA bus slot using a parallel card with ECP mode and Windows 95/98. NT 4.0 does not support ECP mode, and PCI cards do not have DMA access. computer hardware

EEPROM

- Electrically Erasable Programmable Read Only Memory - memory that retains data even when the power is off. EISA - Extended Industry Standard Architecture. A 32-bit PC expansion bus designed as a superset of the ISA bus. Designed to expand the speed and data width of the legacy expansion bus while still supporting older ISA cards. ISA bus cards can plug into EISA slots. printers

EMI/RFI

- Electro Magnetic Interference/Radio Frequency Interference: signals generated by expanding/collapsing magnetic fields such as motors, transformers, arc welding, fluorescent/neon lighting, radio/television Transmitters, motor brushes, lightning. EMI/RFI Immunity - The level at which a device or signal is unaffected by EMI/RFI Enhanced Address Decoding - technology

Decoding of the full 16-bits of the ISA bus address and the full 32-bits of the PCI bus address. Some interface cards don t decode the full address. This means that such a card will respond to commands at more than one address, so that conflicts with other cards are more likely. Decoding the full address prevents a card from causing conflicts. mainframe

Enhanced Timer Mode

- A timer feature used to prevent slave devices from receiving preamble commands, inadvertent switching from binary/graphic file transfers, and inactive slave devices from holding control of the master port. The switch can monitor the data line, if there is not any activity for a specific time it will disconnect from the master. Alternately, the switch can ignore commands for a specific amount of time. samsung

EPP

- Enhanced Printer Port - a printer port that has additional registers and generates the handshaking signals in hardware. Compared to a standard printer port which requires several port writes and reads for each byte transferred, once a EPP port is set to EPP mode, only one write is needed for each byte. EPP software is required to use the EPP port in EPP mode, otherwise it functions as a SPP (Standard Printer Port) or BPP (Bi-directional Printer Port). computer repair

Ethernet

- A type of LAN invented by the Xerox Corporation and developed in cooperation with DEC and Intel. The original Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Originally Ethernet was specified to transfer data over thick coaxial cable at a speed of 10 Mbps. Now the term Ethernet typically encompasses all of the versions of the IEEE standard, which has adapted to include higher data rates and different media, including thin coaxial, twisted-pair, and fiber optic systems. used computers

The most common types of Ethernet in use today are 10BaseT, which uses twisted pair cable at 10 Mbps, 100BaseT (or Fast Ethernet), which uses twisted pair cable at 100 Mbps, and 1000BaseT (or Gigabit Ethernet) which uses twisted pair cable at 1 Gbps. Fiber optic cable is also a popular medium for each of the connection speeds. network

Ethernet Port Server

- A device that connects to the LAN with Ethernet connections. It may provide serial services to the network, printer services, CD-ROM services, Facsimile or other services. Externally Powered - digital cameras
