Spider Power Options
The ADS Spider is designed specifically for low power, battery-
operated applications. The standard battery complemented with a
solar panel can provide sufficient power for many months of
unattended operation.
Two user-selectable options provide advanced power management
for special applications.
Always-on Operation
The ADS Spider is normally in the
“
sleep
”
state. This state is
indicated by a blank LCD display. The system automatically
“
wakes-
up
”
as required to scan analog inputs, log, receive & send text
messages and e-mails, etc. It remains
“
awake
”
for the shortest
possible time and then goes back to
“
sleep
”
.
The main advantage of the LP (Low Power) mode is greatly reduced
power consumption and increased battery life. The LP mode is the
default mode and recommended for most applications.
The disadvantages of the LP mode are the following:
1. Ethernet (Local Area Network- LAN) port is not available
during
“
sleep
”
.
2. Analog channels are not scanned during
“
sleep
”
.
It is possible to keep the system continuously
“
awake
”
by selecting
the
“
Always-on
”
power mode.
IMPORTANT NOTE:
Advanced power settings should only be changed by
experienced users. Selecting the
“
wrong
”
option can result in
an inability to remotely connect to a Spider, drastically reduced
battery life, or even complete battery failure.
