Install GPRS Modem Gateway with a GP1, DL6 or GP2 logger
Powering the modem when using GP1 or DL6 Loggers
Power to the GPRS modem is supplied via the cable harness in
the Modem Box. Power is brought to the DIN rail either directly
from the battery via a fuse or indirectly via the solar regulator
charger. From the DIN rail it connects to both the modem and
also to the external 8-way GP1 network cable socket built into the
side of the Modem Box.
This means that the battery power is also accessible to any GP1
or DL6 logger externally connected on the GP1 cabling network.
(If you don’t want this to happen, the wiring at the DIN rail can
easily be altered. See Cable harness wiring scheme on page 27).
WARNING: Cover the solar panel when wiring up the system, as
it will be live.
