"Bad addr" message on passenger panel

"Bad addr" message on passenger panel

The command from the operator panel has a standardised format that includes an address byte. The message on the passenger panel indicates that the format received is unexpected.

The fault could be with the operator panel, load cell cable or the passenger panel, causing corruption of data transmission/reception, and the fault could be intermittent or permanent. Sometimes a message like this could be caused by the activation of a conveyor motor, with the spike as the conveyor starts, momentarily disrupting the transmission. The latest passenger panels have additional firmware to eliminate this momentary error.

We advise that you try to swap the passenger panel with an adjacent unit, and then the load cell cable to see if either of these parts is the cause.

Ensure that the passenger display cable is separated from mains or other data lines that could result in cross talk between the data lines.

If it’s a momentary fault as described above, it may be simpler to replace the passenger panel with the latest unit from Atrax.
