Command "CR_TEMPFAIL”[CR] 

Details 

Get the temperature inside a projector when abnormal temperature occurs. 
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 temp. (External temp.) 
%b ------------------ Sensor 2 temp. (Internal temp.1) 
%c ------------------ Sensor 3 temp. (Internal temp.2) 
 
[Example] 
“_31.5F”[CR] 
“_” indicates a space. When the temperature sinks to -, the first 
character is “-” like “-05.5F”[CR]   
The last character means the sensor’s status if it reaches 
abnormal temperature 
 

Exceeding critical temp. ------------------------------ “F” 
Temp. is safe -------------------------------------------- “S” 
Sensor detects no critical temp.--------------------- “N” 

 
The example shows that sensor 1 indicates 31.5 degrees and the 
temperature is abnormal. 
When the temperature is safe, all data are represented as 
“□000S”. 
When the projector is reset, “□000S” is set, and every time 
abnormal temperature occurs, it renews the data and returns it. 
In short, it only returns the renewed data of the latest abnormal 
temperature and the previous data is deleted. 

Unacceptable  “Error Code” [CR]
