I don't think you can talk to the projector directly for that; I only did a single project with an Alchemy and I'm using a projector macro to put it to sleep. It's triggered by sending the following command 'PROJECTOR.Execute Macro,"PROJECTOR_SLEEP";' and it's via TCP port 43748. FWIW I am also using simlar macros for selecting flat/scope/input selection.
Wake is done by triggering an I/O port, which is possibly physically located on the ICMP, for 3.5 seconds. Our Cinema guy configured and commissioned the projector in such a way that I only had to trigger the Versi out.
Maybe, but just maybe, you could use Wake-on-LAN? But it's a tough one: we don't know if it is possible, and even then - would you use the Projector's MAC addr or the ICMP's one? Luckily I didn't need to go down that road..
I can send you the complete Barco ref guide (TDE7907) for the Alchemy if you'd like.
Good luck!
