2-6 Communication Sequence
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
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
When the requested data was received normally from the external device, the laser marker transmits response data for
normal receiving 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 until
receiving the response.
