Used to retrieve the on/off status for a powered piece of hardware. Available parameters are
ACTIVELED (Active LED), ETHERNET (10/100 BaseT), SW12V (Switched +12V) , and the 5VREF (+5V
Reference) whose status’ can be read, returning a 1 for On or 0 for Off.
GETPOWER ACTIVELED, var REM stores the status of the Active LED in var
GETPOWER ETHERNET,var REM stores the status of the Ethernet port in var
GETPOWER SW12V, var REM stores the status of the Switched +12V in var
GETPOWER 5VREF SLOT1, var REM stores the status of the +5V Ref in var
GETPOWER
Used to send a command and retrieve its response on the SDI-12 bus. The given command can
optionally contain the trailing exclamation point (“!”) and automatically performs retries. The

REM Retrieve the second measurement parameter from an SDI-12 sensor
REM SDI Measurement commands return 5 characters (atttn)
REM a = sensor address, t = seconds to measure, n = # of measurements
GETSDI “0M!”, var$ REM returns 00022
delay_time$ = mid$(var$, 2, 3) REM stores 002 in delay_time$
delay_time = val(delay_time$) REM stores 2 in delay_time
DELAY delay_time REM waits for 2 seconds
sdi_cmd$ = “0D0!”
GETSDI sdi_cmd$, var$ REM returns 0+2.941+.012
var$ = mid$(var$, 2) REM saves +2.941+.012 in var$
ARRAY arr$(1) REM declare our array for use with TOKEN
result = TOKEN(var$, arr$(), “+-”) REM separate based on + or -
FOR param = 1 TO result REM result = 2
IF (param == 2) THEN
var2$ = arr$(param)
END IF
NEXT param
PRINT var2$ REM prints .012
