DESCRIPTION

The interface_power utility is used to simultaneously switch on and off the power to the following peripherals:

GPS
OPC
NDIR
modem (2G only on Praxis/Urban, all modems on Praxis/OPCube)
integrated gas sensor interface (digital side only)
LED

Note that not all interface board types are able to switch off all of these subsystems. Where switching is not possible, no operation is performed, and no exception is raised.

LED control is direct - it bypasses the led_controller process, if running. This enables LED control in service stop situations, where led_controller service may already have stopped. If the ENABLE_ALL flag is used, the LED is set to amber.

The utility supports a switch of any combination of peripherals, or all peripherals. Note that, in the case of 'all' the modem is not included.

SYNOPSIS

interface_power.py { [-g ENABLE] [-p ENABLE] [-m ENABLE] [-n ENABLE] [-o ENABLE] | ENABLE_ALL } [-v]

Options
--version	show program's version number and exit
-h, --help	show this help message and exit
-g GASES, --gases=GASES	switch gas sensors ON (1) or OFF (0)
-p GPS, --gps=GPS	switch GPS receiver ON (1) or OFF (0)
-m MODEM, --modem=MODEM	switch modem ON (1) or OFF (0)
-n NDIR, --ndir=NDIR	switch NDIR sensor ON (1) or OFF (0)
-o OPC, --opc=OPC	switch particulate sensor ON (1) or OFF (0)
-l LED, --led=LED	set the LED to the given colour
-v, --verbose	report narrative to stderr

EXAMPLES

All peripherals (except modem):

./interface_power.py 0

OPC only:

./interface_power.py -o 0
