Projectors Questions & Answers

Q: We’ve noticed that some new projector models have an RJ45 input on them. Can you clarify what exactly this feature allows us to do and what the real life application would be?

A. You are correct that RJ45 jacks are now being introduced on mid range XGA projector models from the leading manufacturers. This feature does truly make your projector a networkable device and offers some impressive benefits with very little added cost.

The units we’ve tested come with software that once loaded on your pc, allows you to view the status of the projector from wherever you are as long as you are on the corporate network.

A great example is the new Hitachi CPX268 model. You can use this model in a LAN environment for centralized monitoring of such things as power, inputs and lamp hours. With the free network software that comes with the unit, more than 500 projectors can be monitored from a single PC. It is also possible to actually control the power and other functions of any of these projectors connected via LAN. In fact, the software is so powerful it can be configured using Simple Mail Transfer Protocol (SMTP) to send a warning message via email to up to five designated email addresses when certain issues arise.

From an asset management perspective this is a great feature as you can ensure the projectors are being turned off when not in use, which reduces lamp hours and overall cost of ownership. For a help desk perspective this can be very useful as you’ll know when a problem is occurring often before the actual user even does!
