1. Power Connection
The main connector is an Anderson Power Products SB120 style power plug.
The mating plug has + / - labeled as to the correct orientation.
2. Ground Stud
There is a ground stud on the front panel to protect the panel from being
inadvertently energized, connect this stud to a known good ground.
3. Comm Port
The communication connector is a standard RJ45 connector. There are several
protocols being used in various versions of MKM. Initial versions have I2C
protocol as standard. Future models will have SMBus and CAN Bus, among
others. The Communication port is used for State of Charge and other internal
battery statuses.
Verify the version MKM you are using and the communication protocol before
proceeding. Please consult the factory for additional communications protocol
information.
The communication port requires an external +5/3VDC and Ground connection to
properly function. The port is fully isolated from the battery by an ADUM1250.
The pin out is as follows:
Pin 4 – I2C Data
Pin 5 – I2C Clock
Pin 7 - +5/3VDC
Pin 8 – Return (-)
Available registers are listed at the end of the Manual.
