LV-7490 Expand Serial Command Functional Specifications
1.
Overview
1.1
This Functional Specification defines communication functions for LV-7490.
1.2
Compatible to Firmware Ver. 1.x of the projector.
1.3
Most commands can be used to control projector remotely from PC by RS-232C. Therefore, the
commands are defined as Expand Serial Commands.

Notes for communication
1.
Expand Serial Command is defined as one command / one line that starts with “C” and ends
with carriage return (0x0D)
2.
There are two types of commands: Functional Execution Command and Status Read
Command.
- Example of Functional Execution Command:”CF_BRIGHT_032”[CR]
- Example of Status Read Command: “CR_RIGHT”[CR]
Note) ”_” means a space
3.
When it takes more than one second to receive one command, it is not executed.
When it takes more than one second to receive carriage return (0X0D) after the projector
receives the first data “C”, it clears the information of buffer.
4.
On command pipelining, wait for the interval of 100ms till sending next command after receiving
a response.
(More than 100ms)
Command
PC → Projector
“CF_BRIGHT_032” CR
Projector → PC
Next Command
“000” CR
Response
(A few ms - 5s)
When a computer sends next command before receiving a response, the projector may not
operate properly, except when there is no response for more than 5 seconds.
5.
It takes about 5 seconds for internal initialization after plugging in AC power. During this time
commands cannot be processed. Do not issue any command.
4. Name Definition
1.
Data from a controller to a projector is represented as COMMAND, and data from a projector to
a controller for the incoming command is represented as RESPONSE.
2.
[CR] : Carriage Return Code
Command ends with cartridge return code.
Response also ends with carriage return code.
3.
_ : Space Code
A space Code is indicated by (_).
4.
%1 : Parameter in Command
When there are several parameters, they are defined as %2, %3…
5.
%%% : Error code returned from a projector
Acceptable: “000”.
Unacceptable: See [7. Error Code Table].
6.
%a : Parameter in Response Command
When there are several parameters, they are defined as %b, %c…

“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.

%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.
Response
%1,%2,%3
“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.

%a ------------------ Sensor 1 temp. (External temp.)
%b ------------------ Sensor 2 temp. (Internal temp.1)

[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
Response
%a
%b
%c
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.
