9.12.7 CR_TEMP Command
Command "CR_TEMP”[CR]
Details
Get current temperature inside a projector.
If there are several sensors installed, it is possible to get information from all the
sensors at once.
Acceptable
“000_%1_%2_%3”[CR]
%1,%2,%3
%1= Sensor 1 temperature (Outside temperature)
%2= Sensor 2 temperature (Inside temperature1)
%3= Sensor 3 temperature (Inside temperature2)
%1,%2 are consists of 6 bites fixed
There must be 1 space between %1 and %2, and, %2 and %3
e.g. _31.5F
“_” means a space and “_” changes into “-“, when temperature
gets below freezing.
e.g. -05.5F
The last character shows if corresponding sensor is under
abnormal temperature.
“F” ------- Abnormal temperature
“W”-------Close to abnormal temperature(Temperature is as high
to display Warning)
“S” -------Not close to abnormal temperature (Temperature is low
enough and safe.)
“N”-------Applicable sensor does not detect abnormal temperature
“E” -------Not able to return temperature data
When several sensors are incorporated, projector returns values
continuously.
e.g. “_31.5F__35.2S__38.0W”[CR]
A data of sensor 1 comes first and a data of sensor 2 follows after
1 space.
As described respectively in e.g., sensor 1 detects abnormal
temp., sensor 2 detects 35.2 degrees which means safety, and
sensor 3 is 38 degrees which is close to abnormal temp.
In case projector cannot return its data due to some hard ware
failure, the last character becomes “E” such as “_00.0E”.
Some of the projectors get abnormal temperature because of
heat of Lamp ballast in Standby mode or Powering ON.
Therefore detection of abnormal temperature is suspended while
Standby mode or adequate time after Power ON, and during that
time projector returns “_----N” as a temperature data.
Response
Unacceptable “Error Code”[CR]
