3. Notes for Communication
3.1 The TV command is defined one command/one line that starts with “C” and ends with carriage
return (0x0D).
3.2 There are two types of commands, Functional Execution Commands and Status Read
Commands.
[Example]
Functional Execution Command: “C05” [CR]
Status Read Command: “CR0” [CR]
3.3 When it takes more than one second to receive one command, the function is not executed.
When it takes more than one second until the TV receives carriage return since it has received
the first data “C”, it clears the information of buffer.
3.4 For the command pipelining, wait interval of 100 ms after the response.
More than 100ms
Command
PC → TV
“C” “0” “7” CR Next Command
TV → PC ACK CR
Carriage Return
（a few ms ～ 5s）
3.4.1 When a command is issued before receiving response, the function is not executed
properly.
3.4.2 Except when there is no response for 5 seconds.
3.5 It takes about 5 seconds
it cannot process commands. Do not issue any command.
3.6 The number of characters of response for Status Read Commands depends on commands.
Please see [7. Status Read Command].
3.7 Characters for commands must be Capital (A - Z).

1) System: issue any commands every 100 ms after receiving response
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 TV receives other incoming commands within 120ms, the execution of pipelining is
stopped.

8. Addressin g Format command
overview
Addressing format command is used for operating multiple TV sets from one PC via RS232C control
line.
Addressing format command is defined one command/one line that starts with “A” and ends with
carriage return (0x0D).
When the TV receives carriage return (0x0D), the TV starts to decode.
Address is added at the top of control command as follows. (Control command is defined as same as
command without address.)
[Example]
Functional execution command:
“A001C05” [CR] means address is “001” and control command is “C05”.
Status read command:
“A001CR0” [CR] means address is “001” and control command is “CR0”.
The TV can set its own address in hotel option menu. Address can be set in the range of “001” to
“999” . Default address is “001”.
The TV clears the information of receiving buffer and the function is not executed when the following
condition occurs.
1) When it takes more than one second until the TV receives carriage return since it has
received the first data “C” and /or
2) When LF (0x0A) or EOF (0x1A) is received.
8.2 Functional execution command with address
8.2.1 Format
1) PC issues a command in format as below.
“A” Address “C” Command [CR]
(PC ( TV) or
“A” Address “CF_ ” Command “_” Parameter [CR] (PC ( TV)
Address: 3 digit number ( 001 to 999 )
Command / Parameter: See Functional Execution Command Table.
“_” means space.
2) Only TV with which address matches responds. The TV returns “ACK”
and decode or returns “?” to PC.
[ACK] [CR] (0x06, 0x0D) When received command is appropriate.
“?” [CR] When received command is not appropriate.
[NOTE]
If received address is “FFF”, all TVs execu te the command but never respond to PC.

1) PC issues a command in format as below.
“A” Address “CR” Command [CR] (PC Æ TV) or
“A” Address “CR_” Command [CR] (PC Æ TV)
Address: 3 digit number ( 001 to 999 )
Command: See Status Read Command Table.
