The BKM-68x is an RGB / Component video input card for the A-Series BVM's. It is the only option
for getting RGB into an A-Series (cards from other models are not compatible) and they are extremely rare and
The BKM-68x cards are both hard to find and very temperamental to use. Many consoles seem to
have sync issues with this card and the A-Series BVM's don't have the "VCR Mode" that the previous BVM's
offered that cleared up a lot of these problems. At the moment (very early in the testing
stages), it looks like using an Extron 580xi might be a good compatibility fix, however more information needs
to be collected as to why the 580xi helps the sync, as well as other methods of forcing
Many of us are also testing every option possible to find a way to get 240p signals into the
A-Series BVM's without using the BKM-68x at all. Our efforts have mostly been futile, but we'll keep trying so
that maybe someday, A-Series BVM owners can have cheaper alternatives for RGB inputs into their consoles.
XGA was nice enough to donate both the operational manual and
the service manual for the 68x:
This video is an overview of some of the common problems of the 68x, as well as possible fixes and
alternative input options. I hope to soon have a follow-up video with more information.
Many A-Series BVM owners are searching for alternative ways to get a 240p RGB signal into the
monitor without using the BKM-68x. At the moment, the only solution found ads one frame of lag and only outputs
480i (as demonstrated in the video above). Any other solutions will be posted here.
XGA also provided a guide on how to access the maintenance menu of the 68x itself, which isn't in the
This is how you access the BKM-68X maintenance menu and also the options that are available (I don't believe
these options are listed any either of the operation manual or service manual for either the A20F1 or the
BKM-68X). If anyone has any suggestions on what options to enable / disable to get it to sync properly with
consoles like the AES, please speak up.
1) Press the MENU button and select "SYSTEM CONFIGURATION..."
2) Select "MAINTENANCE..."
3) Enter the password 53415 and press enter
4) Select the "BKM-68X..." option

Well, that's it for now. I'll update this page as soon as there's any more information on the best ways to
make all consoles compatible, as well as any possible workarounds for the 68x.
