MSO2000 Application module hack
luisprata:
Recently I bougth a DPO2CONN ... But I couldn't get video on my monitor. It shows "15.734KHz / 30 Hz out of range" ...
I suspect that some unused VGA pins are used to Console because there are a MAX3221 routed to this connector.
CPLD is a MAX II EPM570T100
I dont know how the board is detected by the system. Maybe a simple board present, or maybe some CPLD info. I`ll investigate it.
Some internal pictures...
Le_Bassiste:
and here is my DPO2CONN purchased many years ago. right from the beginning, it constantly refused to connect to my home server, so i did some testing around the ethernet phy, only to find out that the !RESET from the FPGA to the phy wasn't properly asserted. a Q&D fix did the job...
luisprata:
Le_Bassiste,
Does your video output work? Could you check H-sync and V-sync frequencies? It will help me a lot.
Thank you.
luisprata:
Do you have any other useful information about this module?
Le_Bassiste:
sorry, nope. module came in sealed original box w/o any description. VGA output works, but can't do any scaling, so it's basically useless anyway. :--
