1 Introduction
In this publication, items relevant only to the TM6102, TM6103, and TM6104 are indicated as “the instrument.”
Various messages are supported for controlling the instrument through the interfaces.
Messages can be either program messages, sent from the controller such as PC to the instrument, or response
messages, sent from the instrument to the controller.
Message types are further categorized as follows. Command Messages
Program Messages Query Messages
Messages
Response Messages
When issuing commands that contain data, make sure that the data is provided in the specified format.
Message Format
Program Messages
Program messages can be either Command Messages or Query Messages.
(1)Command Messages
Instructions to control the instrument, such as to change settings or reset
Example: (instruction to set the red measurement range)
:RANGE:R 1
Header portion Space Data portion
(2)Query Messages
Requests for responses relating to results of operation or
measurement, or the state of instrument settings
Example: (request for the red measurement range that is currently set)
:RANGE:R?
Header portion Question mark
See: “Headers (p.2)”, “Separators (p.3)”, “Data Formats (p.4)”
Program Messages
Response Messages
Controller
Instrument

2
Response Messages
When a query message is received, its syntax is checked and a response message is generated.
If an error occurs when a query message is received, no response message is generated for that query.
Command Syntax
Command names are chosen to mnemonically represent their function, and can be abbreviated. The full
command name is called the “long form”, and the abbreviated name is called the “short form”. The command
references in this manual indicate the short form in upper-case letters, extended to the long form in lower case
letters, although the commands are not case-sensitive in actual usage.
:RANGE:R? OK (long form)
:RANG:R? OK (short form)
:RAN? Error
Headers
Headers must always be prefixed to program messages.
(1) Command Program Headers
There are three types of commands: Simple, Compound and Standard.
•Headers for Simple Commands
This header type is a sequence of letters and digits
:ABORt
•Headers for Compound Commands
These headers consist of multiple simple command type headers separated by colons “:”
:RANGe:AUTO:R
•Headers for Standard Commands
This header type begins with an asterisk “*”, indicating that it is a standard command defined by IEEE 488.2.
*RST
(2) Query Program Header
These commands are used to interrogate the instrument about the results of operations, measured values and
the current states of instrument settings.
As shown by the following examples, a query is formed by appending a question mark “?” after a program
header.
:FETCh:XY:R?
:RANGe:AUTO:R?

3
Message Terminators
This instrument recognizes the following message terminators (delimiters):
• CR+LF
Separators
(1) Message Unit Separator
Multiple messages can be written in one line by separating them with semicolons “;”.
:RANGE:R 1; *IDN?
•When messages are combined in this way and if one command contains an error, all subsequent messages up
to the next terminator will be ignored.
(2) Header Separator
In a message consisting of both a header and data, the header is separated from the data by a space “ ” (ASCII
code 20H).
:RANGE:R 1
(3) Data Separator
In a message containing multiple data items, commas are required to separate the data items from one another.
:TARGET:DEVIATION:X 0.3333,0.01

4
Data Formats
The instrument uses character data, decimal numeric data and character string data depending on the command.
(1) Character Data
Character data always begins with an alphabetic character, and subsequent characters may be either
alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument
are only upper case. When the command data portion contains <1/0/ON/OFF>, the operation will be similar to
when 0 is OFF and 1 is ON.
:RANGE:AUTO:R OFF
(2) Decimal Numeric Data
Three formats are used for numeric data, identified as NR1, NR2, and NR3. Numeric values may be signed or
unsigned. Unsigned numeric values are handled as positive values. Values exceeding the precision handled by
the instrument are rounded to the nearest valid digit.
•NR1 Integer data (e.g.: +12, -23, 34)
•NR2 Fixed-point data (e.g.: +1.23, -23.45, 3.456)
•NR3 Floating-point exponential representation data (e.g.: +1.0E-2, -2.3E+4)
The term “NRf format” includes all three of the above numeric decimal formats.
The instrument accepts NRf format data. The format of response data is specified for each command, and the
data is sent in that format.
:RANGE:R 16
:FETCH:WAVELENGTH:CENTROID:R?
6.3478E+02 ,0
(3) Character string data
•Character string data is enclosed by quotation marks.
•This type of data consists of 8-bit ASCII characters
•As for quotation marks, the sender from the instrument uses double quotes (”).
:SYSTEM:MAC?
Response> “00-01-67-07-03-85”

5
Compound Command Header Omission
When several commands having a common header are combined to form a compound command
(e.g., :RANGe:AUTO:R and :RANGe:AUTO:B)if they are written together in sequence, the common
portion (here, :RANGe:AUTO) can be omitted after its initial occurrence.
This common portion is called the “current path” (analogous to the path concept in computer file storage), and until it
is cleared, the interpretation of subsequent commands presumes that they share the same common portion.
This usage of the current path is shown in the following example:
Full expression
:RANGE:AUTO:R 0;:RANGE:AUTO:G 0;:RANGE:AUTO:B 0
Compacted expression
:RANGE:AUTO:R 0; G 0; B 0
This portion becomes the current path, and can be omitted from the messages immediately following.
The current path is cleared when the power is turned on, by a colon “:” at the start of a command, by a colon “*” at
the start of a command, and when a message terminator is detected.
Standard command messages can be executed regardless of the current path. They have no effect upon the
current path.
A colon “:” is not required at the start of the header of a Simple or Compound command. However, to avoid
confusion with abbreviated forms and operating mistakes, we recommend always placing a colon at the start of a
header.
Output Queue and Input Buffer
Input Buffer
The input buffer capacity of the instrument is 1024 bytes.
If 1024 bytes are allowed to accumulate in this buffer so that it becomes full, the LAN interface bus enters the
waiting state until space is cleared in the buffer.
Note: Ensure that the no command ever exceeds 1024 bytes.

6
Event Registers
Standard Event Status Register (SESR)
The Standard Event Status Register is an 8-bit register.
The Standard Event Status Register is cleared in the following situations:
•When a *CLS command is executed
•When an event register query (*ESR?) is executed
•When the instrument is powered on again

semantic error:
•Program header error
•Incorrect number of data parameters
•Invalid parameter format
•Received a command not supported by the instrument
•The specified data value is outside of the set range
Bit 4
EXE
Execution Error
This bit is set to 1 when a received command cannot be executed for
some reason.
•The specified setting data cannot be set
•Execution is prevented by some other operation being performed
Bit 3
DDE
Device-Dependent Error
This bit is set to 1 when a command cannot be executed due to some
reason other than a command error, a query error or an execution
error.
Bit 2
QYE
Query Error (the output queue is cleared)
This bit is set to 1 when a query error is detected by the output queue
control.
•When the data overflows the output queue
•When data in the output queue has been lost
Bit 1
RQC
(Unused)
Not used by this instrument
Request Control
Bit 0
OPC
Operation Complete
•It indicates the execution of an “*OPC” command.
•It indicates the completion of operations of all messages up to the
“*OPC” command

7
Device-Specific Event Status Registers
This instrument provides Event Status Register 0 for controlling events. The Event Status Register is an 8-bit
register.
Event Status Registers 0 is cleared in the following situations:
•When a *CLS command is executed
•When an Event Status Register 0 query is executed
(:ESR0?)
•When the instrument is powered on again

Command Execution Time
Command execution time indicates the time for analyzing and processing long form commands.
However, the command execution time for commands with data is the time described in accordance with the data
format specified in the <data portion>.
•Display delays may occur depending on the frequency of communication processes and process contents.
•All commands except *TRG are processed sequentially.
•In communications with the client, time must be added for data transmission.
•Wait until measurements stabilize after a change before using a setting command.

Color Expressions
Expressions such as R, G, B, and RGB are used in syntaxes and descriptions. Their meanings are as follows.
R: Red
G: Green
B: Blue
RGB: RGB mixed light (Three colors, R, G, and B, are mixed.)
Unit of Radiometric Quantity
The unit of the radiometric quantity is omitted in descriptions. Each instrument uses the unit as described below.
TM6102: [W/m2]
TM6103: [W/sr•m2]
TM6104: [W]
Unit of Photometric Quantity
The unit of the photometric quantity is omitted in descriptions. Each instrument uses the unit as described below.
TM6102: [lx]
TM6103: [cd/m2]
TM6104: [lm]

Cautions on Communication Program Creation
The TCP/IP communication performs the process so that large data is sent efficiently. Therefore, when small data
such as a command to control the instrument is sent, the send process may not be performed until the size of the send
data reaches a certain level. In this case, the response from the instrument becomes slow. Therefore, when creating a
communication program, perform the following settings to make the response from the instrument faster.
•For Socket Program
Set 1 for TCP_NODELAY of the socket option.
Example: C/C++)
SOCKET sock;
BOOL opt;
•••
opt = 1;
setsockopt(sock, IPPROTO_TCP, TCP_NODELAY, (char*)&opt, sizeof(BOOL));
• For .Net Framework
Set NoDelay of the TcpClient class to true.
Example: VB)
Dim tcpClient As System.Net.Sockets.TcpClient
•••
tcpClient.NoDelay = True
