batteries are inserted correctly. Note: Rechargeable batteries can be used, however
they must be recharged outside of the unit in a standalone battery charger.
USB Type B Connector
Refer to Diagram: The USB connector is a common type B connector found on a
variety of electronic devices. This port will be used to transfer stored grid/log files,
captured screen shots, etc. This connector will also be used to upgrade the MAX II

MAX II is USB type A to USB type B.

"Remote Commander". The primary purpose of the Remote Commander is for
system integration to be controlled by a PC. An accessory 9 pin female serial to
Lemo 1 - 5 pin male cable will be required to use this feature, and is not included in
the standard kit.
