Overview
This specification defines projector control commands for the 103-019101-01(LW600).
The projector control commands are designed to remote-control a projector through RS-232C from a
computer.
See 8. Commands with Address Specification when using commands with address.

Notes for Communication
The projector command is defined one command per line that starts “C” and ends carriage return
(0x0D).
When the projector receives the carriage return, it starts decoding.
There are two types of commands:

Functional Execution Commands
Example: “C05” [CR]

Status Read Commands.
Example: “CR0” [CR]
The buffer clears the information it stores in the following cases.

When the projector receives LF (0x0A) or EOF (0x1A9).

When it takes more than one second to receive a single command.
(Until receiving the carriage return after the reception of the first data.)
When pipelining control commands, allow interval time as below after the reception of response,
1) [ZOOM UP/DOWN] [FOCUS UP/DOWN] [LENS SHIF UP/DOWN/LEFT/ RIGHT]
commands…100ms 2)
2) Other commands…500ms
When pipelining Status Read command, allow at least 500ms of interval time after the response.
Do not issue any command before receiving the response except the case that there is no response for
5 seconds.
It takes about 7 seconds for internal initialization after plugging in AC. During this time, it cannot
process command. Do not issue any commands.
For 7 seconds after starting POWER ON in the status of STANDBY, the projector returns
“Acceptable” response, but it does not carry out the command. Status Read commands are carried out
in 500 ms after the “Acceptable” response is returned.
During Count Down and Cooling Down operation; in the period of the Count Down operation after
Power ON or Cooling Down after Power OFF, “Acceptable” response is returned, but the command is
not carried out except for Status Read command.
During switching inputs; it takes 5 seconds to switch inputs after receiving the command. During this
period, even if another command is received, it is not carried out although returning “Acceptable”
response. However, Status Read commands are carried out in 500 ms after the “Acceptable” response
is returned.
The length of the returned value for Status Read command in successful operation depends on the
command.
The characters for commands must be in uppercase (A - Z). Lowercase can not be used.

The PC issues a command in the format below:
“C” Command [CR]
The command: has two characters
See Functional Execution Commands Table.
A projector decodes the received data and returns the result after getting ready to receive another
command.
[ACK] [CR]: (0x06, 0x0D) when the projector has received Functional Execution Commands.
“?” [CR]: When the resceived data cannot be decoded
6.2
Command Pipelining
Functions which need command pipelining follow the rule below.
6.3

Sender system issues any command every 100ms.

When receiving the applicable command, the function is executed for 120ms from the moment.

When receiving the same command in succession within 120ms, the function is executed for
another 120ms from the moment.

When there is no incoming command after 120ms, the execution of pipelining is stopped.

When the projector receives incoming other command within 120ms, the execution of pipelining
is stopped.

Commands with Address Specification
8.1
Overview
Commands with an address are used to control more than one projector remotely through RS-232C by
a single computer.
The command with address is defined as a single command per line that starts with an ”A” and ends
with carriage return (0x0D).
When a projector receives carriage return (0x0D), it starts decoding.
The address such as “A001” is prefixed to the Basic Serial Command or Expand Serial Command
already mentioned:
e.g.) Functional Execution Command: “A001C05” [CR]
e.g.) Status Read Command: “A001CR0” [CR]
The projector has the function to set up its own address in Service mode.
Initial setting is “No. 001.”
The available range of values is “001” to “999”
The projector clears the data in the receive buffer under following conditions.

When receiving LF (0x0A) or EOF (0x1A).

When it takes more than one second to receive a single command. (until receiving a carriage return
after the reception of the first data.)
It returns the response within 60ms.

Status Read Commands
The only projector that have the address number matching with the one included in the received data
decodes the command, and when it gets ready to receive another command, it returns one of these two
responses:

[ACK] [CR]: When receiving Functional Execution Command (0x06, 0x0D)

“?” [CR]: When the received data cannot be decoded
However, when the address is “FFF”, the projector executes the function but does not return any
response.
8.2.2 When the command pipelining is needed
Functions that need command pipelining follow the rules below.
8.3

Sending-side system issues commands every 100 ms

When receiving an applicable command, the function is executed repeatedly for 120 ms.

When receiving the same command in a row within 120 ms, the function is repeatedly executed for
another 120 ms from the moment.

When there is no incoming command after 120 ms, the execution of pipelining is stopped.

When the projector receives other command within 120 ms, the execution of pipelining is stopped.
Status Read Command with Address
8.3.1 Format
The PC issues a command in the format below:
The only projectors that have the address matching with the one in the received data decode the
command, and it returns required data.
