Elite Touch car-operating panels and CIB interface boards

The keypad cannot reach its CIB boards over the CAN bus, so the update cannot be sent. A common cause is a bad factory-crimped CAN connector between two CIB boards; once the wires are landed directly in the screw terminals the upload goes through.

How the update normally works:

1. The update flash drive carries two files: a .BTE file (the job program) and a long-named .BMD file (the graphics). Leave both on the drive.
2. Plug the drive into the USB port on the keypad. It loads the long-named .BMD file first, then restarts and loads the .BTE file, then tells you it is OK to remove the drive.
3. If the .BTE job program never loads, the keypad can come back up normally after a power cycle and register some car calls, but floors handled by the program (for example the lobby call made with the * key) return “access denied”.

What to check, in order:

1. DIP switches. Example for a job with one stacked CIB-D48 (three boards) plus one standalone CIB-D16: the stacked set has all S1 DIP switches OFF, the standalone board has S1 switch 6 ON (its floor range follows the job print). On the keypad board, the middle bank of the three DIP banks is all ON except positions 1 and 8; the other banks are all OFF. The small S2 slide switch and jumper J10 on the CIB boards are not relevant to this problem.
2. Termination jumpers. Only the two ends of the CAN chain are terminated. In this example the chain runs keypad → stacked CIB → standalone CIB → operating-mode board. Jumper JP7 next to the keypad’s CAN connector is shorted (terminated), jumper J3 above the CAN connector on each CIB board is open, and the last board on the chain is terminated.
3. Measure the bus. Set the meter to ohms and read between CAN H and CAN L on any board in the chain (it does not matter which end you measure from). Typical readings:

Reading between CAN H and CAN L	Meaning
About 57–60 Ω	Both terminations are seen – bus is continuous
About 117–118 Ω	Only one termination is seen – there is a break somewhere in the chain
About 39–40 Ω	Three terminations are installed – remove one

4. Find the break. With 117 Ω on the bus, move a temporary termination jumper from board to board. If adding it on the standalone board gives 59 Ω but moving it to the stacked board gives 118 Ω again, the break is in the link between the stacked board and the standalone board.
5. Fix the connector. That link uses the small insulation-displacement connector on the side of the CIB board. Pull those wires out and land them directly in the orange CAN screw connector together with the existing wires (two wires per terminal). The bus should then read about 57.5 Ω with the extra jumper removed, and the USB upload should complete.

Also: do not move the processor chips (the labeled CE Electronics PIC on each board) between CIB boards – they belong to the board they are in. The blue LED on the operating-mode board should blink continuously, about every second or two, when that board is running.

The meaning of the two-digit LED on the CIB boards is not documented here. With a broken bus, a stacked board may show “6” and a standalone board “FF”. Treat “FF” as a hint to check the CAN link and termination as described above rather than as a known fault code.

Verify with CE support.

The touchscreen is receiving CAN packets from its CIB board (that is what lights the button), but the controller is not accepting the call, so the button drops out. If the CIB board has already been replaced without any change, the controller is most likely not seeing the bit the board sets.

What to check:

1. Make sure the DIP switch address on the CIB board matches the controller’s input address for that call. For example, a front down hall call at a landing with address 8 bit 2 is S1 switch 6 ON with 1–5, 7 and 8 OFF, and the second DIP bank all OFF.
2. In the controller, make sure that input address is enabled and mapped to the hall-down (or car call) signal. CE cannot change this; it is a controller setting.
3. The jumper next to the orange three-pin and green two-pin plugs on the CIBOS board (J3, near R56) is the CAN termination. Set it the same as the board you removed. On a short CAN run it makes little difference whether it is on or off.
4. Check the serial-link cable and connectors between the CIB board and the controller for a broken or intermittent connection; this fault can come and go over a period of weeks.
5. If the screen shows a “no response” type message when you press a button, that points back at the CIB board; if the screen looks normal and only the latch drops, suspect the controller side.

Note: on older installations the replacement CIB board may need a specific legacy code version so the bit assignments do not move. Check this when ordering a replacement.

Verify with CE support.

Something outside the CE system is wired or configured wrong. The touchscreen itself only connects to the CE interface board over the three-wire CAN link, and the call inputs/outputs are landed in the field, so a buzzer that CE never controls cannot be driven by the touchscreen unless wiring or controller programming is crossing over.

1. The nudging buzzer should be driven only by the controller on its own input/output; it should not be wired into the CE enclosure at all. Trace how it ended up in the circuit.
2. Check the field-landed input wiring in the CE box on the car top. A mis-landed 110 V wire there is enough reason to re-check the whole enclosure.
3. Make sure the controller is in its normal operating mode. A controller in a different mode can echo signals back and trigger the wrong outputs.
4. Note which button starts the problem – it typically begins partway down the list of floors and continues from there, which helps narrow the affected inputs.

Verify with CE support.

The display orientation setting no longer matches the design loaded on the unit. This usually happens after the screen or the ET190 CPU board has been repaired or replaced, or after the board was connected to a different screen.

1. Make sure the CPU board is connected to the correct screen, then power cycle the CPU board: remove the 120 V feed from its power supply (not just the J23 plug), wait about 30 seconds, and reapply. It does not need a shutdown like a normal computer.
2. If the CE boot screen itself is still rotated, the orientation has to be changed in software. On newer Elite Touch software there is a check box on the CE start-up screen to rotate the display. On older software you need to plug a keyboard and mouse into the USB ports on the CPU board and change the orientation in the display settings.
3. Have the serial number of the unit ready so CE support can tell which software version is installed and load the design on a test screen.

Verify with CE support.

If the screen never gets past “Starting, please wait” after a power cycle, the electronics are not booting and need to go back to CE for repair. The likely cause is a processor failure on the electronics. CE tests the electronics together with the screen, so send both; contact CE support for a return authorization before shipping.

No. The ET190 is the 19-inch Elite Touch touchscreen CPU and the EW150 (EW150-PL2 / EW150-CL2) is a 15-inch portrait display; they have some similar connectors but are not interchangeable and the ET190 will not fit in the EW150’s place.

• If the EW150 is working, leave it as found. The ET190 CPU board belongs to the touchscreen, which is a separate unit used in place of the car buttons.
• The touchscreen CPU board is normally mounted at the back of the COP or, if there is no room, on top of the car.
• On the EW150 auxiliary display, the three-pin plug that lands on the four-terminal J10 header is accessory power (most likely the fans): land it on one COM and the two +12 V terminals, not on both COM terminals.
