Bc2000 (for the BCF2000 & BCR2000)

scanned through the midi implementation document, but I wasn't sure of
myself, and I know there are people here who know a little more than I do.
I'm thinking of sending sysex to the BCR to change the lcd state.
As far as I can tell the .mode command will do it. 
I think an example might help me explain:

- I have a bcr preset, sending cc's into a Max patch which is a midi
translator. Encoders are all initially set to 1 dot.
- The Max preset emulates the Frontier Alphatrack, akin to Mackie
Control Emulation, but always based on the selected track rather than
banks of eight tracks. It also receives sysex from my host, which
indicates e.g. levels, and on/off state, of effects.
- If I receive a message from the host into Max, which states On or
Off, I would like to be able to send a message to the BCR which sets
the encoder led ring to e.g. 12 dot, and send a value to represent On
or Off visually.

Max, in case you don't know, is a visual programming environment,
useful for dealing with midi. Google maxmsp.

So, can that be done?
Can I just convert BCL messages from ascii to hex (sysex)?
which commands would I need to send for something like that... just
$encoder?

Thanks,
Matthew
