D-2 V440-F C-Mount Code Reader User Manual
D-1 Introduction
With WebLink, configuration changes can be made in the menus and then sent and saved to the
reader. The user can also send serial commands to the reader via Terminal.
The following describes the basic flow of the serial (RS-232C) communications.
•
Match RS-232C communication parameters (baud rate, parity, data bits, and stop bits) between the
reader and the host.
•
Send the read command “< >” from the host to reader.
•
Send the “read result” from the reader to the host.
The serial (RS-232C) communications use serial commands stated in this manual.
For example, “Read” commands are described in Chapter 5
Read Cycle
.
The following describes the basic flow of the serial (TCP) communications.
•
The reader opens a port (default: 2001) as TCP server at startup.
•
The higher connects to the reader as a TCP client.
•
The host sends the “read command” “< >” to the reader .
•
The reader sends the “read results” to the host.
The serial (TCP) communications use serial commands stated in this manual.
For example, “Read” commands are described in Chapter 5
Read Cycle
.
The following describes the output format of serial (RS-232C, TCP) communications.
<Header> Read strings <Footer>
In default, the header is “None” and the footer is “CR+LF”. The header and footer can be changed with

For example, When reading a code of 12345, the default output data is below.
Addition to read strings, coordinate information of a read code and the print quality evaluation
information can be added.
