Firmware for MCX402DR-BRD expanders
Copyright Roger Sp. z o.o. sp.k.

Notes to firmware versions:
MCX402DR-x.hex -> Firmware for operation with PRT readers (RACS CLK/DTA). It can be also used to convert PR402DR and PR402DR-BRD controllers (RACS 4 system) into MCX402DR expanders
MCX402DR12VDC-x.hex -> Firmware for operation with PRT (RACS CLK/DTA) and Wiegand readers. It is used ONLY for conversion of PR402DR-12VDC and PR402DR-12VDC-BRD controllers (RACS 4 system) into MCX402DR expanders.
MCX402DR-WG-x.hex -> Default factory firmware for operation with Wiegand readers. It can be also used to convert PR402DR and PR402DR-BRD controllers (RACS 4 system) into MCX402DR expanders
