Ahh. Either way, the pinout of 30 and 87 seems reversible.
You can also use a Resistor-Capacitor Low-Pass Filter to convert a PWM signal to a constant 12V. I don't believe there is a way to get a 100% duty-cycle from the LCM.
Edit:
Some google search says LCM might have some access to the PWM options per circuit via PA Soft.
