1700 Series Wafer Reader Section 3: Configuring a Wafer ID Application

LKx5 Protocol
The In-Sight wafer reader supports several Siemens LKx5 commands that allow the
wafer reader to be controlled from users’ custom application programs over an RS-232
connection.
COMMANDS DESCRIPTION
BC Request to read a barcode.
BC&OCR Request to read both the barcode and OCR string.
BC|OCR Request to read a barcode or OCR string.
DDM Request to read the 2D mark.
DDM&OCR Request to read both the 2D mark and OCR string.

OCR Request to read an OCR string.
READ Request to read any mark in this order: OCR, DDM, BC.
ROT_KOMPR Request reading a barcode from right to left.
SET_HW Echoes the input argument. This command is provided for compatibility only; it does not
affect light settings.
VERS Request the firmware version of the wafer reader.
Port
Assigns the TCP/IP port number to use when ‘Network’ is selected in the Trigger or
Output Destination settings. This port number is where a TCP/IP connection is
established between the wafer reader (a TCP/IP server waiting for communication) and a
remote device (a TCP/IP client that initiates communication). The default port is 2000, but
any unused number between 1 and 65535 may be used, excluding 21, 23, 68, 80, 502,
1069, 1070, 1212, 2222, 44818 and 50000 (reserved for In-Sight communications).
Output String, Output Score, Output Passed
These checkboxes select the results data that will be sent to the Output Destination after
a read. By default, only the Output String box is checked. When the
Output Passed
checkbox is enabled, the resulting data is either a ‘1.000’ if the read passes or ‘0.000’ if
the read fails.
3.6.3 Logging
Read results may be written to a log file saved on a network host. Logging options
specify which results are written to the log file.
Host Name
The name or IP address of the remote host on the network where the log file will be
created.
File Name
The name of the file on the specified host where log entries will be appended. The log file
is an HTML document; the .HTM extension is automatically appended to the File Name.
