Command “CR_TEMPWARN”[CR] 

Details 

Get the temperature inside a projector and its condition if it is abnormal 
temperature or close to abnormal temperature 
If there are several sensors installed, it is possible to get information from all the 
sensors at once. 

Response 

Acceptable “000_%a_%b_%c”[CR] 

%a 
%b 
%c 

%a -------------------- Sensor 1 status 
%b -------------------- Sensor 2 status 
%c -------------------- Sensor 3 status 
 
    “W” ---- Approach or reach abnormal temperature   
         (dangerous temperature) 

“S” ---- Far from abnormal temperature (safe temperature) 
“N” ---- Sensor detects no abnormal temperature 

 
[Example] 
  “S_W_S”[CR] means Sensor 1 detects safe temperature, Sensor 
2 detects abnormal temperature and Sensor 3 detects safe 
temperature 
Note) When the temperature difference between Sensor 1 and 3 
reaches specific value, some of the models detect it as Abnormal 
temperature. In this case, the 3rd data shows if the temperature 
difference between Sensor 1 and 3 is dangerous state or not. The 
3rd data means temperature abnormality due to Sensor 3 
When abnormal temperature is not detected by sensor, “N” (No 
connection with temperature abnormality) is returned.   

Unacceptable  “Error Code” [CR]
