A.1.1.3 Powering the Sensor
The A200 provides power to the GPS16X-HVS when it is connected to a PC’s
USB port. An internal DC/DC converter boosts the 5 Vdc supply from the
USB connection to a 12 Vdc output that is required to power the sensor.
A.1.1.4 Determining which COM Port the A200 has been Assigned
When the A200 is loaded, the A200 is assigned a COM port number. Often,
the assigned COM port will be the next port number that is free. However, if
other devices have been installed in the past (some of which may no longer be
plugged in), the A200 may be assigned a higher COM port number.
Often, the assigned COM port will be the next port number that is free.
However, if other devices have been installed in the past (some of which may
no longer be plugged in), the A200 may be assigned a higher COM port
number. To check which COM port has been assigned to the A200, you can
monitor the appearance of a new COM port in the list of COM ports offered in
your software package (e.g., LoggerNet) before and after the installation, or
look in the Windows Device Manager list under the ports section (access via
the control panel).
A.1.2 Using the SC110
The SC110 consists of two cables—each has a 2-foot (0.6 m) length. Use the
cable that has a 9-pin female connector (DCE). TABLE A-2 shows wiring.
