information.
When installing the antenna system:
• Choose an antenna location that has a clear view of the sky so that each satellite
above the horizon can be tracked without obstruction. (Refer to the Multipath
section in the GPS+ Reference Manual).
• Mount the antenna on a secure, stable structure capable of safe operation in the
specific environment.
3.2.4 Connecting the Antenna to the Receiver
Connect the antenna to the receiver using high-quality coaxial cable, as discussed in Section 3.1.2 on
Page 34.
The DL-V3, ProPak-V3 and FlexPak enclosures provide a TNC female connector, which can be
connected to the antenna directly with any of NovAtel’s coaxial cables. For the OEMV cards, an
interconnect adapter cable is required to convert the TNC male end of the coaxial cable to the card’s
MCX (OEMV-1/OEMV-1G) or MMCX (OEMV-2/OEMV-3) female RF input connector. The
location of the RF connector for the each of the OEMV cards is shown in Appendix A, Technical
Specifications starting on Page 129.
The SMART-V1 is a combined receiver and antenna, therefore no external antenna connection is
necessary.
3.2.5 Applying Power to the Receiver
Connect the power supply, set to the voltage given in Table 3, Voltage Input Range for OEMV on Page
35, to the wiring harness created previously.
For a DL-V3, ProPak-V3, FlexPak-V1, FlexPak-V1G, FlexPak-V2 or SMART-V1, connect a power
supply to the power port. For the DL-V3 you can choose to press its power button or wait for the
power sequence, see DL-V3 Power Down and the Power Button starting below. See also Table 4,
Enclosure Power Requirements on Page 35.
DL-V3 Power Down and the Power Button
DL-V3 incorporates a power button on its front end-cap, see Figure 6 on Page 26. Pressing this
switch, sends a signal to the microprocessor to turn on or off the GNSS receiver.
The DL-V3 has a low-power mode called power-down mode. To enter this low-power mode, press the
power button for at least three but no more than seven seconds, then release it. This is also the mode
the receiver enters into after applying power.
In the power-down mode, all logging is disabled.
While power consumption in power-down mode is minimal, less than 10 μA, the DL-V3 is not
completely off. If power conservation is important in your application, disconnect the power source
from the DL-V3 when it is not in use.
Press the power button momentarily to turn the DL-V3 back on. Also, the DL-V3 monitors its serial
ports, and becomes fully operational as soon as serial port activity is detected. For example, if a key is
