Document Camera Feedback

I'm working with document camera feedback to show the power status in case someone turns it on or off without using the control panel. The problem is that the response has a space in it.
Can I put a space in find_string(data.text," ") OR can I put an ELSE statement in STRING / DATA_EVENT??

When power is on I get $B0a$80$02$00$BF
When power is off I get $B0a$80 $00$BF

This works if it is turned on from the camera.

DATA_EVENT [dvDocCam]
{
STRING:
IF(LENGTH_STRING(data.text))
{
SELECT
{
ACTIVE (FIND_STRING(data.text,"$80,$02",1)):
nDocPwr = DPWRON
}
}
}

Can I put a space in there data.text,"$80, ",1)):

I tried to put an ELSE statement in there (IF it's not ON then it must be OFF) but that didn't work.
