IMPORTANT: Some controllers (like the TSMPPT) contain
two microprocessors. These units will need a rmware
update for each processor. Such update les will be
designated ‘A’ and ‘B’.
The preceding steps assume the Morningstar unit has an on-board RS-232 connection. The next

For controllers/inverters (not Meter accessories) with a standard RJ-11 MeterBus
TM
port, an MSC
adapter (Section 2.1.1) is needed. The adapter will interface the controller/inverter’s RJ-11 port
with your computer’s (or USB adapter’s) serial port.
