searching for information about lanbox lcx- digital outputs

Hello!

I am working on an art research project about synaesthesia and
liveart and am in the process of constructing an instrument that is
built around notions of synaesthesia- extending the capabilities of a
pump (reed/parlor) organ from 1895 via physical computing so that
when played it will emit combinations of sound, light, projected
imagery, aromas, etc,

If you would like to take a look, my project website is here: http://
www.notam02.no/motherboard/synaesthesia/

I have a problem that I need to solve, and suspect that there might
be someone on this list who can help me.

I need to control a set of 8 push-type magnet solenoids via the
digital output of a lanbox lcx. I have a custom built box that will
connect to the 37 pin connector for this purpose. I am using max 4.5/
mac os x. I have previously used the max examples available for
control of lights, but I am unsure about the digital outputs. My
questions are: What kind of data is needed to be sent? Do you know
of any documentation about this (can't find it in the lanbox
documentation files/website) and do you know about any existing max
patch examples for this purpose?

with best wishes
