1. Acknowledgement Response Return Codes Advanced For some functions it is possible to obtain a more detailed response from the projector This is useful where different actions are required depending on the current projector settings or status To request the detailed response taking the above example of the Power Command we would send to the projector 3F 89 01 50 57 0A If the projector receives the enquiry command as a confirmation that it has received the command it will first respond with exactly the same information as that returned by the basic Acknowledgement Return Code shown on page 8 06 89 01 50 57 0A Next the projector will send the detailed response It will send 40 89 01 50 57 RR 0A Where RR is the Detailed Response Return Code For clarity the two returned responses are separated here In practice they are returned from the projector as one continuous string For the power Status Enquiry the possible values for the Detailed Response Return Code status RR are 30 Standby 31 Power On 32 Cooling 34 Emergency So as a full worked example if we send to the projector 3F 89 01 50 57 0A If the projector were currently cooling down after being switched to Standby it would return 06 89 01 50 57 0A 40 89 01 50 57 320A If the projector were on Standby it would return 06 89 01 50 57 0A 40 89 01 50 57 300A A list of all of the useful enquiry codes together with all possible detailed
