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
, 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.
