Typical power and signal cabling scheme for use
with a GP2 logger controller.
Figure 6 shows the modem powered from a GP2 logger via its 5-
way M12 serial cable connector. This GP2 itself is receiving power
from an external battery via a solar power regulator.
WARNING: Cover the solar panel when wiring up the system, as
it will be live.
Power may also be supplied directly to the GP2 serial cable as
shown in the GP2 network cabling diagram on page 26.
