282-2 Communication SequenceThe communication sequence of this product mainly consists of the sequence where the laser marker transmits theresponse 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 themarking end verification (MST) command.⿎ Reception timeoutThe time-out duration of this product is set to 10 seconds from receiving the telegraphic message from the head till the endtransmitted from the external device.If a reception timeout occurs, the telegraphic message transmitted will be discarded and the laser marker will not transmitthe response data.To resume the communication, transmit the correct telegraphic message once again.⿎ Communication sequence of setting/readout request dataWhen the requested data was received normally from the external device, the laser marker transmits positive response tothe 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 beforereceiving the response.Laser markerPositive response (ACK)Send ReceiveReceive SendCommand (setting request data)External deviceReadout responseSend ReceiveReceive SendCommand (readout request data)⿎ Communication sequence when the request data for setting/readout cannot be acceptedWhen the request data transmitted from the external device to the laser marker are not acceptable, the laser markertransmits negative response.Laser markerNegative response (NAK)Send ReceiveReceive SendCommand (setting/readout request data)External deviceME-LP-GS-SR-COMP-3
