Figure 18. Network diagrams
For the PVA-1000S/600+ with SolSensor, communication can be direct from the PC to
each of the instruments or either of the instruments can act as a relay.
The network reconfigures itself automatically to achieve the longest transmission range
between your devices. For example, suppose you are measuring at a combiner box and
your PC is directly linked to both the I-V Measurement Unit and SolSensor. Then you
move your PC and the I-V Measurement Unit to the next combiner box, which happens
to be farther away from SolSensor. The mesh network may then switch to indirect
communication to SolSensor, using the I-V Measurement Unit as the relay station.

If you turn on your I-V Measurement Unit first, it will directly link to your PC. If you
turn on SolSensor first, it will link directly to the PC. The second unit to be turned on
may link directly or indirectly.
