The SPD Keypad Format Tool is a configuration utility used to define, edit, and upload keypad transmission formats for SPD-compatible access control keypads. These keypads typically output Wiegand or OSDP data streams, and the format determines how keypresses are encoded (e.g., 4-bit, 8-bit, 26-bit Wiegand, or custom bit lengths).
