7 Connecting To A Computer
Downloading datalog data to computer requires placing the QRAE II in its cradle and
connecting the cradle to a computer.
The QRAE II’s cradle connects via a DB9 (9-pin) connector to a computer running
ProRAE Remote software.
Press the DB9 connector into the DB9 serial port on the cradle, and then finger-tighten
the two screws on the connector. These keep the connector from coming loose and ensure
the best electrical connection. Make sure the AC/DC adapter is connected to the cradle,
as well, to power the QRAE II and keep its battery from draining.
Note: If your computer has a USB port instead of a DB9 connector, use a USB to 9-pin
serial adapter (part number 410-0210-000).
8 Transferring Data To & From A Computer
Once you have connected your QRAE II cradle to the PC, you can can transfer data,
including a download of the datalog to the computer and updates of firmware to the
QRAE II (should this ever be necessary).
