Where should I download the V2.11.1250 firmware, the divice PSID is MT_1100120019

I have an IB card of CX353A. The firmware version is 2.42.5000. I want to downgrade it to 2.11.1250 to be compatible with the current program. I did not find the download address of this version on the official website. Where can I download it to version 2.11.1250?
