- UP Software – “UP” stands for Upload/Programming software. In Aritech’s ecosystem, this refers to the on-board firmware that manages the keypad’s bootloader and application logic. Sometimes “UP” is misconstrued as “update,” but technically, it’s the operational firmware version.
- V – Stands for Version. This precedes the numerical or alphanumeric revision code (e.g., V1.2, V2.0, V3.1).
- UPD – This is the most critical part. UPD means “Update” . When you see “V UPD” in a file name or display sequence, it signals that this is an updater package—a specific firmware revision intended to be flashed into the UDX75’s non-volatile memory.
