9.11.5 CR_TEMPFAIL Command
Command “CR_TEMPFAIL” [CR]
Details
Get the temperature inside a projector when abnormal temperature status
occurs.
It is possible to get the temperatures all at once when several sensors installed.
Acceptable “000_%1_%2_%3” [CR]
%1,%2,%3
%1 ------------------ Sensor 1 temp.
%2 ------------------ Sensor 2 temp.
%3 ------------------ Sensor 3 temp.
e.g. “_31.5F”
“_” indicates a space. When the temperature goes under 0, the
first character is “-”, not a space, as in “-05.5F”.
With more than one temperature sensors installed, projector
returns responses in a row.
e.g. “_31.5F _ _35.2S _ _38.0W ” [CR]
The first data indicates sensor 1 data, then one space, and
sensor 2 data.
Last character in each data indicates the sensor’s status.
“F” ----------- Exceeding critical temp. (abnormal temp.)
“W” ---------- Approaching critical temp. (Warning temp.)
“S” ----------- Sensor temp. is safe (Safe temp.)
“N” ----------- Sensor detects no critical temp.
“E” ----------- Unable to return the temp. data
The example 1 shows that sensor 1 indicates 31.5 degrees and
the temperature is abnormal, sensor 2 indicates 35.2 degrees
and the temperature is safe, sensor 3 indicates 38.0 degrees
and the temperature is approaching critical state.
When the temperature is safe, all data is represented as
“_00.0S”.
When the projector is reset, “_00.0S” 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.
Response
