*NOTE*
The AS-2518-23 Lamp Driver Module does not use the CD4050 hex driver chips
so ignore that column if that's the style of lamp driver you have.

*NOTE*
I really don't know what this means and I can't find any explaination on the schematic either.
I'm guessing they really mean the solenoid expander board since I didn't find a connection to in
on the lamp driver, but pin 3 on it is ground, so I don't know.


NOTES
I got all this information from the schematics and pretty much copied it verbatim.

If you notice any mistakes (I'm only human), please let me know and I'll fix it up.
