    Hi, What is the M1KAM / Keypad / M1 panel’s reaction to wiegand reads of greater than 26 bit format?

    For example, a reader such as a HID RP40 would often output 26-bit wiegand data from cards so configured, but might also output a longer spill of wiegand data for card reads like an ISO14443 UID / Card Serial Number where it might output 32 bits, 34 bits, etc. In an ideal world, the panel would receive the wiegand spill and discard all but the last and take the relevant last (least significant bit) fields to contrive a 26-bit wiegand spill and process based on that, but I wondered what the panel / keypad / M1KAM would actually do?

    The M1 System supports 26 Bit Wiegand and would not be able to read or respond to other formats.
