Elite PI display models, orientation, audio and language

This is fixed by loading a corrected design file from CE – the two-way screen is tied to a flag in the design, not to the wiring. On a correctly working EMN104 that screen only appears when a two-way device actually triggers it.

Typical symptoms: the display shows the floor number for about half a second, then jumps to “two-way audio video communication – press yes or no”. Inspection and independent service messages still show. Power cycling, unplugging the phone and hard resets do not help, and every car with the same design does the same thing.

Checks to make before asking for a new file:

1. Nothing is plugged into port J3 (the two-way / phone connection). If nothing is connected, the two-way screen should never appear on its own.
2. DIP switch bank S3 – all switches OFF (that is the factory setting on the print).
3. Data voltage at the PI connector, DC volts, common to data (terminals 1 and 3): a positive, fluctuating reading of about 1.5–1.9 V is correct. Terminal 2 is the +24 V supply; if you read a steady 24 V between your probes you are on the wrong pins.
4. If all of that is correct, ask CE support to review the design. If the two-way flags are set up incorrectly in the design, CE’s graphics department sends a new USB installer file; after the update the display works normally and you only have to enter the floor labels.

The old print that ships with the display may label the RJ45 connector for a specific two-way brand; it works with other two-way communication products as well.

Start with the flash drive: it must be 16 GB or smaller and formatted FAT32, with the USB installer file as the only file on it.

1. On a PC, right-click the drive and open Properties. Check File system (must be FAT32 – exFAT does not work) and Capacity. High-density drives (for example a 57 GB exFAT drive) won’t load properly – use a smaller drive.
2. Keep the file name exactly as CE sent it. Delete old copies from your Downloads folder first – if Windows adds “(1)” or other extra characters to the name, the display will not find it.
3. Try loading with the display powered off: power off, plug in the drive, power on. The EMN displays can be finicky about hot-plugging the drive.
4. If it still reports 0 files, erase the drive, reformat it, copy the file again and retry.
5. If the display finds the file but reports a file size error or fails at the end while writing to internal memory, the unit is not accepting the update in the field. In that case CE support will arrange repair.

Yes – the ACH/AIH suffix does not change the design file. If the same file loads on an EMN104-AIH but an EMN104-ACH refuses it, the file is fine and the problem is in the individual ACH unit.

Differences you may notice between the two boards (different screen brand, a 4-wire versus 8-wire backlight cable, a JP5 jumper near the speaker plug on one board) are hardware differences only and do not require a different BND/design file. A serial number of a different display in the file name does not matter either.

The display has no valid design in its flash memory, so it never reaches normal operation. The message sequence looks like this:

What to check:

1. All DIP switches on the back of the unit OFF.
2. The red LED on the back of the board (D25) blinking continuously – that confirms the processor is running.
3. S1 switches 1 and 2 ON brings up the device information screen. In this failure the firmware line reads normally (for example “A126.00.10”) but the next line shows GC = all zeros, i.e. no graphics loaded. Turn 1 and 2 back OFF afterwards.
4. CE support emails the design file for the unit with loading instructions; load it from a FAT32 flash drive as described above.

The design should already be on the display from the factory. A CRC error that does not clear after a reload means the unit needs service.

Verify with CE support.

It is a two-step USB process: first a screen rotation (resolution) file, then a new design file laid out for portrait. Both come from CE support and both must be named USBInstaller.zip (no space) when they go on the flash drive.

1. Ask CE support for the rotation file for your screen size and resolution (for example, an 18.5″ screen at 1920 × 1080). Mention the display resolution so the right file is picked – a file that changes resolution as well as orientation does nothing; the file that rotates and does not change the resolution works immediately.
2. Download the zip exactly as it is – do not extract it (it is password-protected and extracting it breaks the update). Save it to an empty flash drive. Either USB port on the back of the screen can be used.
3. Plug the drive in, wait until the screen says it is okay to remove it, remove it and let the unit reboot. The orientation changes immediately.
4. The direction of rotation is fixed; if the picture comes up upside down for your mounting, physically turn the display 180° in the COP.
5. Delete the rotation file from the drive (or use a second drive), copy the portrait design file – also named USBInstaller.zip – and load it the same way.

If you only load the rotation file and power cycle without the second step, the display still runs the landscape design and the result will look wrong (see next question).

Yes. After rotation the display is still running the landscape design, so the content is wider than the screen. Loading the portrait design file CE sends as step two re-lays out the design for portrait and the content fits.

For a standard EMN70 (or EMN104) on a serial data link, all DIP switches should be OFF; use the device information screen to see whether floor data is arriving.

1. Measure DC volts with black on terminal 1 and red on terminal 3 at the PI plug. A positive reading bouncing between about 1.5 and 2 V is data; 1.3–1.7 V is a little low but acceptable.

2. Turn S1 switches 1 and 2 ON for the device information screen. Near the bottom you will see:

   Field	Meaning
   FA =	Floor ASCII – the floor character received on the link
   F# =	Floor (landing) number received
   MA = / M# =	Message character / number received (for example independent service)

3. Move the car. If FA and F# stay at 1 (and MA is blank, M# = 0 even on independent service), the display is not receiving data – FA = 1, F# = 1 is what a bench unit shows with the data wire pulled.

4. Swap in a known-good source: unplug the 3-pin connector from the working voice board and plug it into the PI (or vice versa). If the PI still shows FA = 1 on that connector, suspect the display; if it starts tracking, suspect the terminal-strip wiring to the PI.

5. On the PI board, confirm terminal 3 is toward the top; the extra 1-2-3-4 silkscreen you may see belongs to an unused 4-pin connector, not the 3-pin plug.

The Elite PI CPU’s speaker output is line level, so a passive speaker can be very quiet; the fix is an external amplifier between the CPU and the speaker.

1. Speaker on the CPU speaker connector (J2), using the two outside pins; speaker impedance 8 Ω maximum (the supplied speaker is an 8 Ω unit).
2. Volume pot next to the speaker connector fully up, and the volume on the video source/encoder at maximum. The encoder has its own gain adjustment as well.
3. DIP switch S1-2 switches audio control between the CPU and the application. If it is already ON, toggling it OFF makes no difference to this problem.
4. If it is still only audible with your ear on the speaker, add an external amplifier. These displays are normally not that quiet, so a unit that stays faint after this should be reported to CE support.

Verify with CE support.

The language is part of the design file, so CE support sends an English design file for your job and you load it from USB; there is no language setting on the display itself.

• Give CE support the job or serial number from the display sticker. Cars can ship with Spanish on-screen text while the voice announcements are in English; CE emails the correct design file.
• Load it with a FAT32 flash drive as described in the USB update question.

Verify with CE support.

When CE repairs a display and has to replace the processor, it can only load the latest design CE has on file for that job. Any design changes made locally (for example a simplified single-car layout done in Elite PI Designer) are not on file at CE and have to be reloaded by whoever maintains the designs on site.

To identify which design a correctly working screen is running:

1. On the upper DIP switch bank (S1), turn switch 1 ON and apply power. An information box appears for about 30 seconds (turn switch 1 off and on again if you miss it).
2. Photograph the box – it shows the name of the running design – and send it to CE support with the job number from the sticker. CE can then check whether a matching file exists.
3. Compare DIP settings between the good and the returned unit; a returned unit may come back with an extra switch (S1-5) turned on.

If the only designs CE has on file are multi-car, the single-car design must be recreated in Elite PI Designer and loaded by USB.

Verify with CE support.

No – newer boards are built that way. The slave board is powered through the large 16-pin aux cable from the master, so it does not need its own power supply.

The coaxial (composite video) connector is no longer standard; CE only fits it when it is specifically requested at order time. Current Elite PI video uses HDMI into an encoder in the machine room. If the building still feeds composite video over coax to the cab (for example for live TV), there is no two-wire or USB adapter input on the new board – either convert the source to HDMI through the encoder, or order the board with the coax port.

No – template changes are made by the CE graphics department. In Elite PI Designer you edit the content within the template; the template shape itself (corner style) and the priority message set (for example French-language fire/emergency messages) are changed by CE and delivered as a new design version to load.
