NOTE: If an attempt is made to activate more than one of the voltage channels at
the same time, the pin that was first activated will be the only channel that is active.
NOTE: Because the 4 pin RJ port is mounted to the bottom of the control board the
pin count reads from right to left as if backwards (see figure 13 below).

NOTE: A four pin RJ plug must be used instead of the regular six pin that is used for
the reg bus. The four conductor wire is fairly easy to find as it is used for telephone
cord. If using pre-made cords carefully observe the wiring colors to make sure that
the cable is pin-to-pin where the wires are always oriented in the same way in both
cable ends similarly to the explanation in the six pin Regbus cable instructions.
Manzanita recommends Tang Down BLACK to the Right for the 4-wire cable.
AC Line Power Meter Options
As of January 1, 2011 Manzanita Micro includes a regular AC current meter built
into the front of all PFC-30, PFC-40, PFC-50 and PFC-75 chargers. This standard
display allows the user to see in real time exactly how many amps the Manzanita
Micro charger is drawing from the AC power source that it is plugged into. This
