Notes for Communication
3.1
The projector command is defined as one command/one line that starts with “C” and ends
with carriage return (0x0D).
3.2
When the projector receives carriage return, it starts decoding.
3.3
There are two types of commands: Functional Execution Commands and Status Read
Commands.
Example of Functional Execution Command: “C05” [CR]
Example of Status Read Command: “CR0” [CR]
3.4
It clears the information of buffer as below.
3.4.1 When the projector receives LF (0x0A) or EOF (0x1A).
3.4.2 When it takes more than one second to receive one command.
(Until the projector returns carriage return since it has received the first data.)
3.5
When control command pipelining, wait the interval of time after the response as below.
3.5.1
[VOLUME +/-] [ZOOM UP/DOWN] [FOCUS UP/DOWN] [LENS SHIFT UP/ DOWN/
LEFT/ RIGHT] Commands
3.5.2
Other Commands
100ms
500ms
3.6
When Status Read command pipelining, wait at least 500ms after the response.
3.7
Do not issue any command before receiving the response except there is no response for 5
seconds.
3.8
It takes about 7 seconds for the internal initialization after plugging in AC. During this
time, it cannot process commands. Do not issue any command.
3.9
For 7 seconds after Power ON from Standby, the projector receives a command and
returns the response but does not execute it because of the internal initialization or Lamp
processing. However, Status Read Commands are carried out after 500 ms when receiving
the response to Power ON command.
3.10
About Count Down and the performance after Cooling Down:
When receiving a command during Count Down after Power ON or Cooling Down after
Power OFF, the projector returns the response but does not carry it out. However, Status
Read Commands are carried out.
3.11
The performance for switching Input:
It takes 5 seconds to switch Input after receiving the command. When receiving the
command during this time, it is not executed. However, Status Read Commands are
carried out after 500ms since it receives the response to switching Input command.
3.12
The number of character of response to Status Read Commands depends on commands.
Please see [7. Status Read Commands].
3.13
Characters for commands must be Capital (A - Z).

6. Functional Execution Command
6.1
Format
6.1.1
PC issues a command in format as below.
“C” COMMAND [CR]
Command: two characters (See Basic Functional Execution Command Table)
6.1.2
A projector changes received data to decode and returns a result after being ready to receive
next command.
[ACK] [CR]: (0x06, 0x0D) When received Functional Execution Commands.
“?” [CR]: When the received data cannot be decoded.
6.2
Command Pipelining
When some functions need the command pipelining, the performance is the same as that of the
remote control.
1)
System: issue any command every 100 ms
2)
When receiving the appropriate command, the function is executed for 120 ms from the
moment.
3)
When receiving the same command continuously within 120 ms, the function is
executed for another 120 ms from the moment.
4)
When there is no incoming command after 120 ms, the execution of pipelining is stopped.
5)
When the projector receives other incoming commands within 120ms, the execution of
pipelining is stopped.

When no temperature data returns due to hardware problems,
the first character is “E” like ”E00.0” [CR].
When the status is Standby or it is 10 seconds after Power On,
depending on projectors, temperature may approach the
abnormal status due to ballast lamp’s residual heat. So, when the
status is Standby or it is 10 seconds after Power On, the process
for the abnormal temperature is not executed. The temperature
data is “ ----” at the time.
Because %4 indicates the sensor 4 data which can only detect two
states of “Normal” or “Abnormal”, the temperature is shown as
“_XX.X”.
With some temperature sensors installed, the projector sends

8. Command with Address Specification
8.1
Overview
8.1.1
Commands with address are used to remote control multiple projectors through RS-232C by
one computer.
8.1.2
The command with address is defined one command/one line that starts with ”A” and ends
with carriage return (0x0D).
8.1.3
When a projector receives carriage return (0x0D), it starts decoding.
8.1.4
This command is represented Basic Command or Expand Command with address such as
“A001”.
(Ex) Functional Execution Command
“A001C05”[CR]
(Ex) Status Read Command
“A001CR0”[CR]
8.1.5
Projector has a function to set up its address in “SPECIAL” – “RS-232C” – “Projector ID” in
the menu.
Initial setting is “No. 001”
Possible range is “001” to “999”
8.1.6
It clears the received buffer in the case as below.
・
When receiving LF (0xoA) or EOF (0x1A)
・
When it takes more than one second to receive one command.
(When it takes more than 1 second to receive carriage return since the projector has
received the first data.)
8.1.7
8.2
Wait the interval up to 60 ms for the response.
Functional Execution Command with address
8.2.1
Format
1)
PC issues commands in format as below:
“A” Address “C” Command [CR]
or
“C” Address “CF□” Command “□” Parameter [CR]
Address: 3-digit number (”001”-”999”)
Commands with “FFF” as the address are available for all projectors.
Command: Character line (See Basic Command or Expand Command)
2)
The only projector with the appropriate address decodes received commands, and when it
is ready to receive next commands, it returns the response.
[ACK] [CR]: When receiving Functional Execution Command (0x06, 0x0D)
“?” [CR]: When the received data cannot be decoded
However, when address is “FFF”, it executes the function but does not return the response.

Command Pipelining
8.2.2
When it needs command pipelining, the operation is the same as the remote control.
1)
PC issues commands every 100 ms
2)
When receiving the appropriate command, projector executes it continuously for 120
ms.
3)
When receiving the same command in 120 ms, the projector executes it continuously
for another 120 ms from the moment.
4)
When there is no command after 120 ms, this execution is stopped.
5) When receiving other commands in 120 ms, this execution is stopped.
8.3
Status Read Command with Address
8.3.1
Format
1) PC issues commands in format as below:
“A” Address “CR” COMMAND [CR]
or
“A” Address “CR_” COMMAND [CR]
Address: 3 digits number (“001”-“999”)
Command: Character line (See Basic Command or Expand Command)
2) The only projector with the appropriate address decodes received commands and returns the
character line as the required data.
Required Data [CR]
Required Data: Character Line (See Basic Status Read Command)
3) When the received data cannot be decoded, it returns “?” [CR].
