• In case of connecting to PLC, a type of the cable (straight or cross) differs depending on a manufacturer or a model.
Please follow the PLC manual.
• To connect RS-232C terminal without using a commercially available RS-232C cable, connect only 3 signals of RxD,
TxD and GND and do not use other signals on the laser marker side.
• The external controller may need a signal line connection (loop back line) other than RxD, TxD, or GND on the external
control device side depending on the specications of the external control device. Read the instruction manual of the
external control device and connect it to the laser marker appropriately.

2-2 Command Reception Condition
ME-LPMSZ-SR-9
■ Command reception permission
When transmitting the communication command including an action to update the laser marker data, commands are
refused in the marking ready ON status or the shutter open. If “reception mode ON” is set for “command reception
permission (MKM command)” before transmitting a command, marking ready is set to OFF and commands get acceptable.
Set “reception mode OFF” for “command reception permission (MKM command)” to set marking ready ON before marking.
Reference
• Commands are acceptable by closing the shutter instead of “command reception permission (MKM command)”.
However, it is recommended to use the “command reception permission (MKM command)” when the number of open
and close of the shutter is a lot.
• The command reception permission (MKM command) does not include actual opening/closing operation of the shutter.
■ Commands acceptable only with shutter closed
(Unacceptable commands when “reception mode ON” is set for command reception permission (MKM command))
• Laser power measurement (PWM)
• Power check (PWR)
• Test marking (TST)
■ Commands that do not need the command reception permission (MKM command)
The following commands can be transmitted while the shutter is opened.
(There is no need to set “reception mode ON” for “command reception permission (MKM command)”.
• File change (specied with a number) (FNO)
• File change (specied with a comment) (FNN)
• Shutter (close only) (SHT)
• Command reception permission (MKM)
• Laser pumping (LSR)
• Counter reset (CTR)
• Status request (STS)
• Marking trigger (MRK)
• Serial offset (SEO)
• Serial data input (SIN)
• Error code (ECR)
■ Commands acceptable during warning/alarm occurrence
The laser marker accepts only the following commands while an alarm or warning occurs.
Alarm
• Status request (STS)
• Error code (ECR)
Warning
• Status request (STS)
• Error code (ECR)
• Shutter (close only) (SHT)
• Command reception permission (MKM) (reception mode ON and reception mode readout)
Reference
• The laser marker should be in the remote status when controlling it by serial communication.
• The Shutter (SHT) command is not acceptable when the No. 2 DIP switch on the back surface of controller is turned to
OFF.
• To release the warning (except error codes E800 to E811) by serial communication control, close the internal shutter
by Shutter (SHT) command or set the “command reception mode ON” by Command reception permission (MKM)
command, and remove the cause of warning.
• An alarm can not be released by serial communication control.

2-3 Connection Check
ME-LPMSZ-SR-9
Check the connection between laser marker and external control device if they are correctly connected.
1. Turn ON the power of the external control device
2. Turn ON the key switch of laser marker.
3. Coordinate the communication conditions between laser marker and external control device
Refer to “1-2-2 Communication condition setting” (P.14).
4. Set the laser marker to the remote mode
Refer to “1-2-3 Shift to remote mode” (P.15).
5. Change the le number of the laser marker (transmit the FNO command)
Start code
STX
02 46 4E 4F 53 32 30 34 37 30 35 0D (HEX)
The transmission data above is just a sample. Check sum ON/OFF and delimiter content vary depending on the
communication environment settings.
*1 : For the command above, calculate the check sum value as follows:
Convert the data from the start code to those before the check sum into the hexadecimal values according to the
ASCII code table and add them all together. Check sum is the value calculated by converting the lower two digits of
the total value into two characters in the ASCII code.
• 02(HEX) + 46(HEX) + 4E(HEX) + 4F(HEX) + 53(HEX) + 32(HEX) + 30(HEX) + 34(HEX) + 37(HEX) = 205(HEX)
• 30 35 (HEX) is the value converted the lower two digits character (lower one-byte) 05 (HEX) into two characters
in the ASCII code
6. Check the response from the laser marker
When the connection and communication condition settings are appropriate, the laser marker returns response data.

2-5 Communication Data Format
ME-LPMSZ-SR-9
Use the ASCII code basically and the shift-JIS code partially as characters for communication when controlling the laser
marker by external device.
The characters (or character strings) enclosed with double quotation marks (“ ”) in the description below indicates that
they uses the ASCII code.
When using the shift-JIS code, it is described in each case.
2-5-1 Command data
The word “command” means the instruction which is sent to the laser marker from external device. Command data is
created with the specied format. Remote control of laser marker or execution of specied procedures are possible by
sending the command data to laser marker.
■ Command data format
Start code
Single character
Head End
Code Description
Start code A start code is a code to identify the data head. STX: 02 (HEX) xed.
Command A command is specied with three characters. Refer to “3 Communication Command and
Sub command A sub command is an instruction of setting/readout complementary added to a command.

Species one of the characters below.
“S”: Data setting or operation (Set)
“R”: Readout of setting data (Read)
(Note) “S” or “R” cannot be selected for some commands.
The content to be specied varies per command. Refer to “3 Communication Command and
Function” (P.34)
Check sum indicates the lower 1-byte of adding result of value (binary) from the start code
to the last data by converting it to two characters by ASCII code.
Where the command is “ABC”, sub command is “S” and data is “000”
02(HEX)+41(HEX)+42(HEX)+43(HEX)+53(HEX)+30(HEX)+30(HEX)+30(HEX)=1AB(HEX)
AB(HEX), the lower 1-byte of 1AB(HEX) is converted to 41(HEX)+42(HEX) to two
characters by ASCII code.

*2 : You can select [CR] or [CR+LF] for a delimiter in case of RS-232C. [CR] is xed in case of Ethernet.
Reference
• The laser marker recognizes the data from the start code (STX) to the delimiter (CR or CR+LF) as one command data.
If there exists an unnecessary character string before the start code or after the delimiter, it is ignored (neither an
abnormal response data is returned).
• When using the external device set by 2-byte, NUL (00 (HEX)) can be used.
• Add to NUL before STX or after delimiter.

Selects CR+LF or CR on the console. Refer to Operation Manual for the details.
2-5-2 Response data
ME-LPMSZ-SR-9
Response data is data which is returned from the laser marker for the command sent by an external device and consists of
the following three types.
1. Response data for normal receiving
The data starts with the start code “ACK”. It returns when the command transmitted is normal or the command
processing has been completed normally.
2. Response data for abnormal receiving
The data starts with the start code “NAK”. It returns when the command transmitted is abnormal or the command
processing has been completed abnormally.
3. Readout data
The data starts with the start code “STX”. It returns when the command transmitted is normal and the sub command
is specied to “R”.
■ Response data format for normal receiving
