Response Data
There are three types of the response data the laser marker sends back against the command data sent from
the external device as follows.
1. Normal reception response data
The start code of this response data is started with “ACK”. If the command is normal, or if the command
processing is ended normally, this response data is sent back.
2. Abnormal reception response data
The start code of this response data is started with “NAK”. If the command is abnormal, or if the command pro-
cessing is ended abnormally, this response data is sent back.
3. Readout data
The start code of this data is started with “STX”. If the command is normal and the subcommand is
expressed with ‘R’, this response data is sent back.
Normal Reception Response Data Format
Description of Each Code
Name
Description
Start Code
Fixed with “ACK” (code: 06
(HEX)
). This is the code for identifying the head of the data and
recognizing the data is normal receiving response data.
Response Code Sends back 2 characters ‘00’ for ACK.
Check Sum
Data that the lowest 1 byte is expressed with 2 characters of ASCII code by adding the
codes from start code until data in binary
E.g.: 06
(HEX)
+30
(HEX)
+30
(HEX)
=66
(HEX)
When converting ‘66
(HEX)
’ into 2 characters, it becomes “36
(HEX)
+36
(HEX)
”.
The valid/invalid of the checksum is available to be set in the environmental setting related
to the laser marker of the LP-310 setting software.
