For many years we are searching the question of projectors network applications -which will be the best network connection for projectors. At least if found to be installed and remote maintenance or remote control, as provided for the LAN capability if needed. What does this if it is concrete and what alternatives are there?
The attribute “network” says first of all not more than that the projector is able to have a software / hardware with other devices – usually computers – to communicate. What information, but through the network to? In the simplest case involves one or more projectors from a remote control room on their operating status to be reviewed and certain functions such as switches or the signal source selection from there. Such functionality is not necessarily connected to a Custom Cable network.
About the serial interface into the net
For years have projectors for the purpose of remote maintenance / RS232 remote control interface. With proprietary protocols can be as many functions and also the operating states of central body search. Unfortunately, the RS232 several disadvantages. On most hindering is that the connection to another computer or access to the next field of media control is not very long. Also, the remote maintenance / remote control via RS232 fairly inflexible, as it is a point-to-point connection.
However, with it the universal network connecting a projector feasible. You need only ensure that the projector associated with the computer control signals to implement that they have a normal LAN (local area network) or even worldwide via the Internet can be transported. This is nothing more necessary than that of the projector via RS232 associated relay computer via a network connection and to implement the necessary software.
The advantage of such a network connection is that so older projectors network. As a disadvantage, however, must be seen that the computers are in operation.
Universal network capability also for the image transport
A step further some supplier of peripheral equipment. You have the computer power and software in a separate case. This serves as an independent and totally maintenance-free relay station for the implementation of the RS232 commands into TCP / IP protocol. Even the transportation of the image signals from the network is in some models. In practice, it looks like this, depending on the version that one or two cable from the projector to lead Relay: a RS232 or USB cable for the control and if necessary, a VGA cable for the image information. The Relay ensures that picture and control signals via IP protocol fed into the grid or from this are received.
In this way, not only the majority of users of older projectors from the benefits of the network connection. The Custom Cable connection of other audio-visual equipment or technology to the universal network of such devices.
Networks and the Internet are open and thus accessible to everyone. Protection measures must be taken so as not to anyone with a network tool for the network projectors for fun and all the devices on and off events and thus disrupts or lamps to burst. Here are the producers of network products requested to take appropriate measures.
Network Custom Cable to the projector
Modern projectors usually have their own computer performance and so it is obvious it with an Ethernet port to provide them directly via IP protocol to address them. Such equipped projectors can be without additional hardware mostly with the existing local network and then to anyone on the computer network is made accessible. The devices will usually receive a fixed IP address through which they can be addressed. Of course, the network connection is not in the local area, but can on the Internet at any desired addressees managed. This offers completely new possibilities for remote maintenance and control of projectors. So many devices offer the possibility, in the event of a fault alone one with a precise fault message to a preset address to send. A service provider is capable of extremely fast to respond to breakdown the existing disorder and possibly even by remote maintenance or to resolve a service technician with detailed information about the nature of the problem of Custom Cable directly to the customer to send.
