Can-I-Bus is the debut album by rapper Canibus, released on September 8, 1998 through Universal Records. The album was released after the rapper's success with his LL Cool J diss track, "Second Round K.O.", which was included on Can-I-Bus, with additional support from heavyweight boxer Mike Tyson. However, the album received mixed reviews. The beats, created mostly by Wyclef Jean, were criticized for their blandness and unoriginality (with a fair amount of the criticism coming from Canibus), but lyrically, the…

What is an industrial Ethernet switch: In terms of performance, there is no difference between an industrial Ethernet switch and an ordinary switch. From the network level, there are two layer switches, and of course three layers of switches. Industrial Ethernet switches in the product design and components selection is to have cultured, it is an industrial field use demand, the machinery, such as climate, electromagnetic environment is relatively poor, still be able to work properly, so, often can be…

Fiber Optic Media Converter is a short twisted-pair electric signals and optical signals over long distances to swap the Ethernet transmission media conversion unit, also known as the photoelectric converter at many places. Products commonly used in Ethernet cable can't cover, optical fiber must be used to extend the transmission distance of actual network environment, and usually located in broadband metropolitan area network access layer of the application. In traditional Ethernet, the medium of connection is the double stranded wire.…

Since 1992, The CAN data link layer and the CAN high-speed physical layer have been standardized internationally in ISO 11898. In the beginning, the standard was published in a monolithic document, but in 2003 it was divided into several parts: Part 1 standardized the CAN data link layer protocol and partly the physical layer (especially the bit-timing); Part 2 specified the electric voltage level on the bus-lines for transmission speeds up to 1 Mbit/s; it also includes some system design…

1 Fiber Optic's Type More than 1.1 multimode fiber optic multimode fiber is the optical fiber that can transmit multiple optical conduction modes. At the beginning of the optical fiber communication, is the use of multimode fiber (g. 651 fiber), the working wavelength at 850 nm and 1300 nm, the attenuation constant of the < 4 db/km respectively and < 3 db/km, the dispersion coefficient of < 120 ps/respectively (nm) km) and < 6 ps/(nm) km). Due to its attenuation…

Power over Ethernet (PoE) technology enables ordinary Ethernet network cables to function as power cords. In a PoE-enabled network, direct electrical current (DC) flows over the network cable together with normal Ethernet data traffic. Most PoE devices follow either IEEE standard 802.3af or 802.3at. Power over Ethernet was designed for use with portable and wireless electronic equipment like ​Wi-Fi access points (APs), webcams, and VoIP phones. PoE allows network devices to be installed in ceilings or wall spaces where electric…

CAN bus in the data frame is sent on the bus, the other CAN controller is through acceptance filtering to determine whether the data on the bus frame ID and this node is consistent, if accord with this node, then the data on the bus were deposited in the bus controller in the corresponding register, or abandon the data, thus able to lighten the load of the bus controller. In other words, the bus data frame ID through after receiving…

As contact with the personnel of optical fiber communication, to the service life of the optical transceiver is concerned about. How long is the service life of it? Industrial-grade fiber optic converter as important optical fiber transmission equipment, in industrial grade fiber optic converter design, the choice of components of nations, it decides the performance of the product, life and cost. Its service life is mainly related to it of light module, the service life of the general in five…
