"Can i use the digital inputs of the AUX port to conenct to the BV7 or just the communication port?"
Yes, the specs say it is possible. But I recommend to use the communication port. Just get a 9 pin cable, cut it, and solder two 3,5 mm stereo jacks to the pins for digital inputs and outputs. Solder a mono jack for RS 485 connection and the Dsub9 plug for RS232. Now connect the cinema out of the BV7 (DSUB9) to digital in of the -238 box (stereo 3,5 mm plug). In this way the AUX port is free for other applications - I use it for an X10 mains switch for my projector and the screen.
"How can I connect the RS232 of the Ilight at the same time as the computer for testing (if possible)?"
Won`t work, I`m afraid. You can`t split the RS232 port...(?) But I have programmed my (one of my...
) -238 boxes, disconnected it from computer and connect it to my 108 relay board by RS232. Now the BV7 controls the projector, screen, light, curtains...
"Do i have to configure the device while connected to the computer then change to the ilight?"
Yes...see above. BTW, I`m highly interested in the ilight system. Do you have some information about the system...pricelist? Do you have the Ineo/Revio switches? And (I heard) they are Beo compatible?-controlable by Beo4/5? Does that work? - Thanks.
"Other option is to connect Rs232 to computer with a split cable and the BV7 at the same time and control the light via IR."
Afaik you can`t split up RS232, but you can connect the BV7 via digital in to the Lintronic box and your ilight system via RS232 and control other devices by IR and digital outputs at the same time, just by configuring macros for the -238 box.
"Does the -238 learn remote signals if they are not in the memory?"
Yes, the -238 box can learn IR commands.
Hope this helps
