Strato

Strato Pi is an expansion board developed by Sfera Labs for the Raspberry Pi computer.

Strato Pi

Strato Pi implements a number of hardware features to expand the Pi and allows its use in professional applications:

• 9-28 Vdc extended-range power supply
• integrated UPS with external NiCd rechargeable battery
• real-time clock with dedicated back-up battery
• opto-isolated RS-232 or RS-485 serial port
• configurable hardware watchdog
• buzzer for audible feedback.

HSYCO Configuration

Add a STRATO I/O Server in the I/O Servers section of the Settings and set its parameters.

Note that the Strato I/O Server doesn't count in the I/O servers license total, so you don't need an extra I/O Server license to use Strato with HSYCO.

High Availability

• Shutdown when inactive: defaults to false.

Options

ID	Default	Values	Description
watchdog	false	true	enables the hardware watchdog and automatically generates the heartbeat signal (use this option only with the Strato UPS board)
		false	disables the hardware watchdog
shutdown_minutes	0	0	no automatic shutdown after power failure
		int > 0	the driver will command the operating system shutdown and hardware power off after N minutes of back-up battery operations during a power failure. The Strato board will automatically power-up the Pi when power is restored (use this option only with the Strato UPS board)
quiet	false	true	enables audible alarms on power failure
		false	disables audible alarms on power failure
version	base	base	Strato Pi Base and UPS boards
		mini	Strato Pi Mini board

Datapoints

ID	Value	R/W	Description
backlight.brightness	<brightness>	R	the current backlight brightness of HSYCO Pi Touch Display
		W	set brightness of HSYCO Pi Touch Display to a value between 0 (off) and 255 (max)
battery	0	R	power supply is available
	1	R	power supply failure, running on UPS battery
beep	0	R	buzzer is off
	1	R	buzzer is on
	off	W	turn buzzer off
	on	W	turn buzzer on (continuous tone)
	<duration>	W	turn buzzer on for <duration> seconds (decimals allowed)
	<duration>;<pause>	W	turn buzzer on for <duration> seconds, then pause for <pause> seconds (decimals allowed)
heartbeat	0	R	heartbeat line is off
		W	set heartbeat line to off
	1	R	heartbeat line is on
		W	set heartbeat line to on
shutdown	0	R	shutdown line is off
	1	R	shutdown line is on
		W	set shutdown line to on (Strato will wait approximately 60 seconds, then execute a power off-on cycle. Once the shutdown line is set to on, the power cycle procedure can't be reset
timeout	0	R	hardware watchdog timeout line is off
	1	R	hardware watchdog timeout line is on. Strato will set this line to on, then wait approximately 60 seconds and execute a power off-on cycle
watchdog	0	R	hardware watchdog is disabled
		W	disables the hardware watchdog
	1	R	hardware watchdog is enabled
		W	enables the hardware watchdog. When enabled, Strato should see an off-on transition on the hearbeat line at least every 60 seconds, otherwise a power cycle will be initiated, setting the timeout line on, then waiting 60 seconds, removing power to the Pi for 5 seconds, and finally restoring power
