Optional LCD Whiteboard

In Shenzhen regarded record of professional introduce you to: Technology Co., Ltd in Shenzhen, regarded as a video dedicated to product development, teaching, touch devices, production, sales and service, specializing in the production of teaching one machine, LCD whiteboard, one PC, touch TV One PC, touch one, touch LCD advertising machine. Company fully implement ISO9001 and ISO14000 quality system certification through the National CCC and CE certification standards. First, the computer interface Type refers to the whiteboard with a computer system in what way to connect. Currently whiteboard connected to the computer common interface types: parallel port (also known as IEEE1284, Centronics) and serial port (also known as RS-232 interface) and USB interfaces. Parallel is also known as a parallel interface. Currently, the parallel interface is mainly used as a printer port, using a 25-pin D connector. The so-called "parallel" refers to 8-bit data simultaneously via parallel transmission line, so that the data transmission speed is greatly improved, but the parallel transmission line length is limited because the length increases, interference increases, the data also error-prone. Currently equipped with a parallel computer basically. Serial called the serial interface of the PC is now generally have two serial ports COM1 and COM2. Differs from the serial port of the parallel port is its data and control information is transmitted bit by bit out. Although this will be slower, but longer transmission distance than the parallel port, so to communicate over longer distances, you should use the serial port. Typically COM1 using a 9-pin D-connector, also known as RS-232 interface, and some are using COM2 old DB25 pin connector, also known as RS-422 interface, but is now rarely used . USB namely "UniversalSerialBus", the Chinese name for Universal Serial Bus. This is a new interface technology in recent years gradually widely used in the PC field. USB interface has faster transmission speed, hot-swappable and features of connecting multiple devices. Now widely adopted in various types of external devices. Currently, there are two USB Interface: USB1.1 and USB2.0. USB1.1 theoretical transfer speed of up to 12Mbps / sec, while USB2.0 can reach speeds of 480Mbps / sec, and can be backward compatible with USB1.1. Second, the panel size is the actual size of the whiteboard, the unit is mm, usually refers Whiteboard length × width three, effective reading size refers to the whiteboard can write effective size used in this area can be any writing and copying output, its size is generally smaller in size than the actual panel. Fourth, under normal circumstances the number of panel whiteboard will feature 1-4 of the panels, the number of panels in two or more cycles may facilitate screen and supports multi-screen content impressions, you can write continuously multi-faceted, user-friendly. Fifth, the output type whiteboard can be written on the whiteboard content scanning and print out a certain way. Its function to complete the process as ordinary copying process, first by the image sensor device dialogue content acquisition board, the acquisition signal after a certain image processing, the final output by thermal, inkjet or other printing. Ordinary whiteboard is to use an external print output device to complete this process, copying whiteboard system comes with a printout can be directly printed output of this process is completed. Print mode output generally have thermal, inkjet and ribbons. Sixth, copying systems whiteboard generally thermal and inkjet types of copy mode output. Thermal way is to use a heated manner of coated printing paper color thermal media, thermal printing system after receiving the print data, copy data into bitmap data, and then follow the control point bitmap data copy system the movement of the heating element by the current, so put the copy data into copy paper copy content. Inkjet way is by ejecting ink droplets onto the medium to copy text or image form. There are continuous inkjet technology and random two inkjet technology. Seven, Copy speed Copy speed is the number of sheets per minute whiteboard can copy, its unit is sheets / min. Note: This article from the My12345.COM collect, compile and edit. Eight, the number of sheets Continuous Replication Continuous Replication refers to the same document does not need to be repeated to set the maximum number of copy of the whiteboard to be continuously done. Because continuous replication avoided duplication of the same manuscript, saving every copy as a home to spend more time, and therefore often need to carry out multiple copies of the same object the user is very practical. Identification method is continuous replication 1 ~ × Zhang, × represents the maximum capacity of this product continuous replication. QQ: 2537602872!
