Figure 9 GPS Time Synchronizing Unit QMG101
GPS Time Synchronizing Unit QMG101 is a GPS receiver with an
embedded antenna for accurate time synchronization. MAWS software
automatically reads the time from QMG101 and adjusts the RTC (Real
Time Clock) if the difference is bigger than the user configurable
maximum allowed. The default is 5 seconds. The unit is usually
installed on the sensor support arm and interfaced via RS-232 with the
logger. QMG101 is delivered with a 3 m cable, a connector, and
installation accessories.
Masts
For equipment installation, there are 10-, 6-, 4-, 3-, and 2-meter masts
available. For detailed product information, see appropriate manuals.
DKP206W and DKP210W are Tiltable Pole Masts, that is, they can
easily be tilted up and down by one person when installing and
maintaining the various devices on the mast. Also special attention has
been paid to easiness and quickness of the mast installation. The
DKP206W and DKP21W0 masts are made of anodized aluminum
resisting well even the most harsh weather condition. The mast is
equipped with a lightning rod and a set of guy wires. The height of the
DKP206W masts is 6 m and that of the DKP210W masts is 10 m.
NOTE
The QMI108 module can only be connected to the QML201 logger.
The type of the logger can be checked with the VER command. In
MAWS Lizard Setup Software the QMI108 module is supported from
software version 4.00 onwards.
