I'm still having all sorts of problems...it definitely seems that having two IO units right next to eachother is really causing an issue. Tonight I am going to seperate the two units and try to put a lot of space between them in order to see if operating them without intference with work while connected to the same bluetooth. I can say that I am getting very frustrated with the necessity to do these diagnosis steps. I am not the quality assurance tester for PacSun...
your having the same issues too? my two I/O are working simutaneously and are about 1 foot apart. this is my setup
my ballasts are hooked up to a DC4 that is controlled by my aquacontroller jr so that if my tank goes up a certain temperature it will turn off one I/O. if it goes above another temperature it will turn off the second I/O. i know the DC4 has some noise filters in there because when i had a icecap 660 and dual galaxy ballasts it wouldnt communicate properly with the acjr; after the dc4 it solved the problem. so maybe its a noise issue with the ballasts hooking up to the same outlet?
i bought a cheap bluetooth for 8 buck s at RE PC.
it came with a driver disk but i had to download the new driver online.
is your driver for your bluetooths updated?
i paired and connected with each I/O separately. noting that i would only power one I/O at a time. one will be com port 9 and the other would be com port 8.
i would first connect the bluetooth to the first I/O then open the pac sun program.
after finishing programming, i would exit out of the pac sun program and then disconnect from the I/O with the bluetooth. then i would turn off that light and proceed to the next light. i would power on the second I/O unit and once done programming i would exit through the pac sun program and then disconnect my bluetooth. then i turn on my other I/O that has been programmed.
i staggered my timing so one I/O will turn on a half hour later after the first I/O.
mine have been working great so far. hopefully this helps
