Power Control - COBHAM Satcom EXPLORER 540 User & Integrator's Manual

3.6 Power control

You can configure the Power mode options with the web interface and with AT
commands.
With the web interface you can set up what should make the EXPLORER 540 enter
power save state as well as how and when to wake up the terminal. For details, see
Power control on page 4-42.
With AT commands you can set up: Idle power save and Remote on/off. See To set up
power save functions with AT commands on page 3-22.
You can choose between three modes:
• Always on. This is the default setting. The terminal will never go into power save
state but will always be on when connected to power.
• Remote on/off. The terminal will go into power save state when the Power
control pin (Remote on/off signal) is inactive. For details, see the following
section Remote on/off.
• Idle power save. The terminal will go into power save state after a (configured)
period with no activity. For details, see Idle power save on page 3-21.
3.6.1 Always on
Always on is the default mode where the terminal stays on as long as power is
connected.
3.6.2 Remote on/off
When Remote on/off is selected in the web interface or with AT commands, you can
control the power save function using the Power control pin (Remote on/off signal).

• Daily awake period
You can configure the function in the web interface (see Power control on page 4-42) or
with AT commands (see Remote on/off on page 3-22).
