I have been fighting with the DSC IT-100 for a couple days now and from the looks on the board there are a bunch of other users that have this combination and it should not be as big of a problem as i am having so i decided to plead for help!
I am using a QM-RMC next to my panel. I verified that the cable is good by plugging it into a laptop and opening a putty session. When i reboot the security system, i can see the date and time so the baud rate is 9600 still and i can see the numbers coming through when i open a window or a door. So the IT-100 is spitting out the feedback.
On the crestron side, i am grabbing all of the data from the output of the panel [rx$] = DSC_rx$ and watching toolbox to see if anything pops, but getting nothing. I also saw that according to the development kit, each line should end with a 0D0A hex so i am using a Serial Gather to try to correctly split up the data that is coming out of the DSC, but nothing is showing in toolbox. Is there some crazy step i am missing when configuring the QM-RMC com port?
I did try my luck with a gefen matrix using the same QM-RMC to make sure that it was not the defect part, and i was able to get feedback and send commands to the gefen so i am thinking that the QM-RMC is OK and its just a configuration step i am missing someplace.
