Fluke RLC - PM6304 serial interface card RS232

[minolta]

Hello,
who has downloaded firmware (EPROM dump 27C1001 - OTP) for serial interface card RS232 (label on my eprom is PM9549 v 2.2 , but probably could be used similar version too).
Has anybody it?
I have unit that can not receive command, sending is OK. I have tested all possible, now I need to check FW.

I can upload main firmware (from the main board) v. 1.8 (EPROM 27C512) if somebody needs this.

Thank you for help!
