⿎
• To connect the laser marker to the PC for control, use a commercially available RS-232C straight cable (laser marker
side: 9pin male).
• 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.
• You may need a signal line connection (loop back line) other than RxD (RD), TxD (SD) or GND on the external control
device side depending on the specifications of the external control device. Read the instruction manual of the external
control device and connect it to the laser marker appropriately.

2 Communication Control
ME-LP-GS-SR-COMP-3
Basics
2-1 Communication Data Types
ME-LP-GS-SR-COMP-3
To control this product by communication commands, the external device transmits request data to the laser marker.
After the laser marker receives request data, it transmits the response data to the external device.
2-1-1 Request data
The request data is sent from the external device to the laser marker. The following types are applicable to the request
data.
Setting request
⿎
Request data to modify or create the laser marker data or to control the laser marker operations.
Readout request
⿎
Request data to read out the status or setting data of the laser marker.
2-1-2 Response data
The response data is sent from the laser marker to the external device. The following types are applicable to the response
data:
Positive response
⿎
Response data transmitted when the setting request data were received normally.
The positive response will be transmitted when the laser marker processing has been completed for some of the command
types.
Readout response
⿎
Response data to transmit the readout content for the readout request data.
Negative response
⿎
Response data to transmit when the request data are not acceptable.
27
2-2 Communication Sequence
ME-LP-GS-SR-COMP-3
The communication sequence of this product mainly consists of the sequence where the laser marker transmits the
response data for the (command) data requested from external devices.
As an exception, the laser marker transmits the response data automatically if you have set the response permission of the
marking end verification (MST) command.
Reception timeout
⿎
The time-out duration of this product is set to 10 seconds from receiving the telegraphic message from the head till the end
transmitted from the external device.
If a reception timeout occurs, the telegraphic message transmitted will be discarded and the laser marker will not transmit
the response data.
To resume the communication, transmit the correct telegraphic message once again.
Communication sequence of setting/readout request data
⿎
When the requested data was received normally from the external device, the laser marker transmits positive response to
the setting request data and transmits readout data to the readout request data.
After sending the command, confirm the response data from the laser marker. Do not send the next command before
receiving the response.
