9.11.8 CR_TEMP Command
Command
“CR_TEMP”[CR]
Details
Get the current temperature information inside a projector.
It is possible to get the temperatures all at once when several sensors installed.
Acceptable “000_%1_%2_%3_%4” [CR]
%1
%1 ------------------ Sensor 1 temp. (External temp.)
%2 ------------------ Sensor 2 temp. (Internal temp.1)
%3 ------------------ Sensor 3 temp. (Internal temp.2)
%4 ------------------ Sensor 4 temp. (Internal temp.3)
%1, %2 are fixed 6 characters
There is one space between %1 and %2
There is one space between %2 and %3
There is one space between %3 and %4
e.g. “_31.5F” : “_” indicates a space. When the temperature goes
under 0, the first character is “-”, not a space, as in “-05.5F”.
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
With more than one temperature sensors installed, projector
returns responses in a row.
e.g. “_31.5F _ _35.2S _ _38.0W _ _ 38.0N” [CR]
The first data indicates sensor 1 data, then one space, and
sensor 2 data.
The example 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, sensor 4 indicates 38.0
degree and this sensor detects no critical temp.
When it cannot return the temperature data due to hardware
error, the last character is “E” as in “_00.0E”
It might happen for some projectors that the temperature
continues to go up to abnormal status as long as lamp ballasts
are hot. Therefore when in Standby mode or for several tens of
seconds after Power is ON, any treatment of Power Failure is not
processed. In that case, the temperature data is represented as
“_ - - - - N”.
Response
Unacceptable
“?” [CR]
9.11.9 CR_SERIALNO Command
Command
“CR_SERIALNO” [CR]
Details Get value of the serial number.
Acceptable “000_%1” [CR]
%1 Eight digits of alphanumeric characters
Response
Unacceptable
“?” [CR]
9.11.10 CR_SHUTCOND Command
Command
“CR_SHUTCOND” [CR]
Details Get setting status of Shutter
Acceptable “000_%1” [CR]
%1
“SAFE” ---------------------- Shutter operation is normal.
”FAIL” ------------------------ Shutter operation is abnormal.
Response
Unacceptable
“?” [CR]
