First, Version 2:
Add something like this to the OUTPUTS section of your skin file:
Code:
#STARTNEW#
#NAME#4ch Amp
#TYPE#RELAY
#DEFAULTSTATE#ON
#IMAGEON#\Black Skin\Digital Buttons\Amp\AmpDOWN.png
#IMAGEOFF#\Black Skin\Digital Buttons\Amp\Amp.png
#SIZE#90,120
#LOCATION#240,296
#SHOWTEXT#false
#PAGE#0
#PORT#8
#VIDPID#MyBrain0
#BORDERSIZE#0
#TIMER#30
#ENDNEW#
DEFAULTSTATE is the important parameter here. Change the rest to suit your setup.
