diagram. Simply remove the cover when replacing the batteries (3 AA cells).
Important: Be sure to follow the polarity labels located on the back label of the
MINI-MAX. Note: Rechargeable batteries can be used, however they must be
recharged outside of the unit in a stand alone battery charger.
RS-232 Connector
Refer to Diagram: The RS-232 connector, located on the bottom end cap, is a 2
pin female Lemo connector. It is designed to connect directly from the MINI-
MAX to a standard AT serial port on a PC. The cable supplied with the MINI-
MAX is a Lemo to 9 pin serial cable. This RS-232 connector is also used to
connect a 2 pin Lemo to 2 pin Lemo serial cable directly to our special shut-off
box, used in conjunction with a pump. Note: This connector is also used to
upgrade the MINI-MAX with the latest version of firmware.
