In addition to the classic barcode readers that can be looped in via the keyboard, readers that are connected via the serial interface can also be connected with the"Serial barcode readers" software option. The advantage of the serial connection is that EULANDA can distinguish whether it is a normal keyboard input or a scanned code from the reader. For example, you do not have to be in the "Barcode" field when selecting an article. And serial interface is not the same as the old RS-232 connection from the 1980s. Modern barcode readers are normally connected via USB and can be switched between keyboard mode and serial mode (often called USB COM).
The following settings are made in the registry under "\MACHINE\.ALLMACHINE\Barcode".
Workstation-specific settings can also be made under the respective PC name in the"Barcode" folder.
|Prefix||An optional prefix that precedes the code.|
|Postfix||If a postfix is specified, EULANDA waits for the complete code before further processing takes place. After 500ms, however, an incomplete code is discarded.|
|TrimCode||Spaces and other whitespaces at the beginning and end of the code are removed|
|StampingDelimiter||DM9500 radio scanners can transmit their own address with the barcode. This enables bidirectional communication with the device.|
User-defined treatment routine for incoming barcodes.
If the scanner can also transmit a quantity specification, this must be separated from the actual barcode by a defined string.
For devices connected via USB, it is sufficient to specify the serial port here
To store additional serial parameters - see the following paragraph
Advanced serial settings
For USB devices that are connected to the PC in serial mode (partly called USB-COM), usually only the COM port needs to be stored. The following text is stored in the "Options" value:
where n is a value between 1 and 9.
If a real serial interface is used, further settings may be necessary. Different settings must be separated by semicolons. Example:
|Name||Data type||Valid values|
|port||text||COM1, COM2, ... COM9|
|stopbits||digits||1, 15, 2|
|databits||digits||4, 5, 6, 7, 8|
|parity||text||NONE, ODD, EVEN, MARK, SPACE|
