Passenger Information Display Systems

Remote monitoring and control

Knowing the status of all the displays in an airport or rail terminal at any one time is impossible, and too often it is the passenger who is the first to notice a blank display or system error message.

Displays that are mission critical, 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.


Sharp/NEC’s professional display products feature advanced connectivity and provide a number of sophisticated tools that allow remote monitoring, notification and control of any display in the operator’s network.

Managing your network

NaViSet Administrator 2 software, free of charge from Sharp/NEC, 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. Any setting that you can normally access via the display’s remote-control unit can be controlled remotely via the NaViSet Administrator 2 interface. The display can be powered on and off (which can also be used to reboot a slot-in device), brightness reset, ambient light sensor or fans switched on or video signal changed. Displays can be grouped into clusters so that one command triggers multiple displays.

Automatic scheduling

One powerful feature of our large format displays is the automated scheduler. The built-in real time clock 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 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.

Self Preservation

Sharp/NEC professional display products may be built into wall recesses, cased in a FIDS tree housing, in a dual back-to-back installation 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 in our display products improves reliability and longevity and protects your display investment.

Displays with intelligence

Our email alert 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

Power supply abnormality
Cooling fan fault
Backlight fault
User configured temperature limit met
FIDs controller / slot-in device abnormality

On receipt of an alert email the network administrator can then use the NaViSet Administrator 2 to determine whether an engineer needs to be called out to site.
