SLU sleep, wakeup

UART sleep/wakeup triggers on/off. Each of the two

parameters can be independently configured as “on” or
“off”. The first parameter specifies sleep trigger (UART
inactivity timeout) setting, and the second one specifies
wakeup trigger (low pulse on UART Rx input) setting.
The defaults are sleep = off, wakeup = on.


Example:

STSLU off, on 

SLUIT sec

Set UART inactivity timeout. The parameter is

specified in seconds (decimal). The default is 1200
(20 minutes).

SLUWP min, max

Set UART wakeup pulse timing. The parameters

are specified in microseconds. The defaults are min =
0, max = 30000 (30 milliseconds).

SLVG on|off

Voltage change wakeup trigger on/off. The default

is off.

SLVGW [+|-]volts, ms

Configure voltage change wakeup trigger. The first

parameter specifies voltage difference between two
samples. The optional ‘+’ or ‘-’ sign, preceding the
voltage, specifies whether the trigger detects only
rising voltage (+), only falling voltage (-), or a voltage
change in any direction (no sign). The second
parameter specifies the time between the samples in
milliseconds. The value specified will be rounded to the
nearest multiple of 250 ms, with any value below 250
being rounded up to the minimum setting of 250 ms.
The default setting is 0.2, 1000 (voltage changing by
0.2V in any direction, with one second between the
samples).


Example:

STSLVGW +0.15, 750 

SLVL sleep, wakeup

Turn voltage level sleep/wakeup triggers on/off.

Each of the two parameters can be specified as “on” or
“off”. The first parameter specifies the sleep trigger
setting, and the second parameter specifies the
wakeup trigger setting. The defaults are sleep = off,
wakeup = off.

SLVLS <|> volts|0xhhh, sec

Configure voltage level sleep trigger. The “<” or “>”

character specifies whether the trigger region is above
or below the threshold voltage: “<” = below, “>” =
above. The threshold voltage can be specified in volts
with the maximum precision of two decimal places. It
can also be specified in raw ADC steps by prefixing the
value with ‘0x’. The sec parameter specifies how long
the voltage must remain above or below the threshold
before the device will enter sleep mode. The default is
<13.00, 600 (below 13V for 600 seconds).

Examples:

STSLVLS <12.85, 60 
STSLVLS >0x8ab, 0 

SLVLW <|> volts|0xhhh, sec

Configure voltage level sleep trigger. The “<” or “>”

character specifies whether the trigger region is above
or below the threshold voltage: “<” = below, “>” =
above. The threshold voltage can be specified in volts
with the maximum precision of two decimal places. It
can also be specified in raw ADC steps by prefixing the
value with ‘0x’. The sec parameter specifies how long
the voltage must remain above or below the threshold
before the device will wake up from sleep. The default
is >13.20, 1 (above 13.2V for 1 second).


Examples:

STSLVLW >13.15, 0 
STSLVLW <0x8cd, 5 

SLX sleep, wakeup

Enable or disable sleep/wakeup triggers associated

with the external sleep control input (SLEEP pin). Each
of the two parameters can be specified as “on” or “off”.
The defaults are sleep = off, wakeup = on.

SLXP 0|1

Configure polarity of the SLEEP input.

0: LOW = sleep, HIGH = wake up
1: LOW = wake up, HIGH = sleep


The default setting is 0.

Note: This command is available only for STN1110

stand-alone IC and microOBD 200 (STN1120).

SLXS

Print the status of the external SLEEP input.

Responds with “WAKE” or “SLEEP”.
