Remote Monitoring and Management of Displays
Knowing the status of all the displays in an airport at any time is impossible, and too often the passenger is the first to notice a display that is blank or has a system error message. Displays that are mission critical to the airport, whether they are revenue generating, informational or directional, or whether they are on their own or in a cluster or contained within a video wall, must be operational at all times, and when errors occur they must be quickly identified and resolved. NEC Professional Display Series products feature advanced connectivity and provide a number of sophisticated tools that allow remote monitoring, notification and control of any display in the airport’s network.
Managing your network
NEC provides the NaViSet Administrator 2 that allows you to remotely monitor and control individual or grouped displays from a centralised point on your network. Using either the RS232 or LAN connection on the display, NaViSet Administrator 2 allows you to connect to the networked display to obtain asset information such as asset location, serial number, number of hours of use, current brightness, input source, as well as status information of the temperature at sensors, power supply, inverter, video signal detection and backlight stability.
Power of control
Once you have determined the status of the display, NaViSet Administrator 2 then allows you to control the display remotely as well. Any setting that you can normally access via the display’s remote control unit, can be controlled remotely via NaViSet Administrator 2 . The display can be powered on and off (which can also be used to reboot one of our in-built FIDS controllers), brightness reset, ambient light sensor or fans switched on or video signal changed. Displays can be grouped into clusters so that one command affects multiple displays. With the same controls available on all our Professional Series displays, supporting a network of NEC Displays couldn’t be easier. Controls typically stay consistent between displays sizes and between generations of our products, allowing long term programming of RS232 control commands.
One powerful feature of all NEC Professional Display Series is the automated scheduler. Each and every display has a real time clock built-in, which allows you to trigger up to 5 commands at particular times of the day. For example, between 1am and 5am you may wish to power down all the displays at check-in, or switch the input signal of the displays to show airline promotional videos. The in-built scheduler can be programmed on a daily, weekly, or monthly basis, allowing for every eventuality. Of course scheduling can be controlled remotely via NaViSet Administrator 2 as well.
NEC Professional Series products may be built into wall recesses, cased in a FIDS tree housing or built into a video wall. Monitoring and managing the temperature of each display is crucial if the display is to maintain its long life. Three in-built sensors monitor the temperature of different areas of the display. Administrators can set the maximum temperature limit of each sensor manually. Once the limit is met, fans can be automatically turned to one of two speed settings. If the display continues to overheat then backlights will be dimmed, and eventually the display will be turned off.
This sophisticated 3 stage heat management system inherent in all NEC display products improves reliability and longevity, and protects your display investment.
Displays with intelligence
A new feature of NEC Professional Series displays is the ability of the display to notify you automatically via email of a problem. Our alert email function allows the network administrator to programme two receiving email addresses into the display. A number of self-diagnosis tests are performed by the display on itself, and will notify the administrator via email on the following detected errors:
- Power supply abnormality
- Cooling fan fault
- Backlight fault
- User configured temperature limit met
- FIDs controller abnormality
On receipt of an alert email the network administrator can then use the NaViSet Administrator 2 to figure out whether an engineer needs to be called out to site.
