Application of Remote Diagnosis Technology in Prepress

The remote control technology in the computer began in the era of dos, but did not attract more people's attention at that time. Many years ago, when we introduced foreign prepress equipment, we could often see some network interfaces. At that time, due to network restrictions, we could only feel the role of Beiren shares. Now the rapid development of such interfaces and software technologies Provides convenience for remote diagnostics.

Below, the author will focus on the application of a conventional diagnostic software and Kodak remote diagnostic technology in prepress, hoping to have some help for CTP system engineers.

Common remote diagnostic software

Remote control generally supports the following network modes: LAN, WAN, dial-up mode, and Internet mode. In addition, some remote control software also supports remote devices through the serial port, parallel port, infrared port to control. Traditional remote control software generally uses NETBEUI, NETBIOS, IPX/SPX, TCP/IP and other protocols to achieve remote control, but on-demand printing, with the development of network technology, many remote control software provide Java technology through Web pages. Controls remote computers, which allows remote control under different operating systems. The evaluation usually refers to control software that is mainly used for normal purpose remote control software. In addition, there are illegal remote control software that is transmitted in the form of virus replication. The Trojan virus type is common.

1. Remote control in Windows system

Remote control is not mysterious Other packaging, Windows XP system provides a variety of simple remote control methods, such as remote desktop connections.

2. Powerful remote control software Pcanywher

PCAnywher is powerful and supports almost all network connection methods and network protocols. With PCAnywher, computer administrators can easily control remote computers on the local computer so that computers in the two places can work together. While implementing remote control and packaging anti-counterfeiting, PC Anywher also has a more complete security policy and password authentication mechanism, thus ensuring the security of the remotely controlled host.

Although PCAnywher's functions are comprehensive, it also has some insurmountable disadvantages, such as too large a software installation package, too slow a window refresh rate, and a long delay when a remote operation is in a poor network condition.

3. Lightweight free remote control software VNC

VNC is a set of free lightweight remote control computer software. It uses the GPL license terms and all the printing, mainly by VNCserver and VNCviewer two parts. Users need to install the VNC server on the computer on the host before they can perform VNC viewer control on the host. VNCserver and VNCviewer support a variety of operating systems, so VNC can be installed in different operating systems for control. The advantage of RealVNC is that if the host computer of the operating system does not have VNC viewer installed, the host can also be controlled through a common web browser.

4. Convenient and practical TeamViewer

TeamViewer is the only remote control software prepress technology that can penetrate the intranet. As long as both parties start the software and accept the connection, remote control can be realized, and remote presentation, file transfer, and online chat are very convenient. Its greatest advantage is that neither party needs to have a fixed IP address, as long as it is connected to the Internet, both parties can control each other and are not affected by the firewall.

Remote diagnostic operation process

Prepress engineers love Agfa at work and most of them prefer to use TeamViewer software for remote diagnosis. The following example uses TeamViewer software as an example to briefly describe the remote diagnosis operation process.

(1) Start TeamViewer for the first time, waiting for a moment will generate ID and password; where the ID number (machine code) is the same, and the password is a temporary assessment, the software will change once once the software starts once (no software modification " Options "related items, the same below." If you are the controlling party, enter the computer ID number of the controlled party into the ID text input box, and click "Connect to Partner". Enter the password generated on the controlled computer later and click "Login".

(2) At this time, the computer desktop of the controlling party is displayed before your eyes and you can control the other computer now. The toolbar displayed on the desktop of the controlling party is not available to the controlling party. It has many functions as described below (where the "file transfer" function is not described in detail).

1 In the "Actions" menu group, "exchange roles with partners" ie "control" and "controlled" identities are exchanged; "remote restart" operations are performed on the controlled computers. If you select “Disable remote input”, the controlled party cannot control his own computer.

2 In the "View" menu group, check "Show remote cursor" to see the movement of the mouse pointer on the controlled computer. This is useful for understanding the other party's operation of his own computer. For example, watching the other party to use Authorware to create courseware is easy for the controller to guide.

3 In the "Extra" menu group, click "record" to record the operation on the controlled computer in an animated manner. The recorded file is saved on the computer of the controlling party and can be used to "play the recorded session." ” Open play. The "dialogue" menu is mainly used for text exchange between the two parties.
