OPERATING MODES

The DL-V3 can either be controlled by a host computer or be set up for stand-alone operation.

•

Controlled Operation: A host computer can transmit logging parameters, receive collected data,
and turn the DL-V3 on or off. Whenever the DL-V3 is connected to a power source (regardless of
whether the DL-V3 is turned “on” or “off”), it detects if there is a host computer connected to one
of its serial ports. If a host computer is found, and there is serial port activity from a host
computer to the DL-V3, the DL-V3 powers up. If the DL-V3’s predefined POWERUP group, see
also Section 4.2.1, Receiver Groups on Page 57, exists in the DL-V3, the DL-V3 runs the
POWERUP group, otherwise the DL-V3 begins to search for satellites and waits for commands
from the host computer.

Only specific serial ports have wake-up capability on data activity. For example, the USB,

Ethernet or Bluetooth

ports do not.

•

Stand-Alone Operation: Once the DL-V3 receives configuration commands from a host
computer, it operates according to these parameters. For example, data collection can be
configured in advance by setting up a group to repeat continually.
