hello First post. i have been asked to add some lights to existing cbus installation. this has been no problem but the existing touchscreen is a 3M touchscreen running windows xp when booting it shows multi media dynamics. this i assume connects to the cbus network by a 5500pc serial interface. the customer has asked me to add these new lights to there touch screen. is this something that i can do or will i have to contact the original installer. i am having trouble finding info on MMD. all help appreciated trevor
