7.5 RS 232 C Data output via interface RS 232 C

RS 232 C Data output via interface RS 232 C
General information
As a condition for the data transfer between the balance and a peripheral device (for instance printer, PC ...)
both devise have to be set on the same interface parameter (for instance baud rate, parity ...).

7.5.1 There are 5 methods for the data output via RS 232 C

Data output via PRINT-Key
The printing process can be released by the PRINT-key. In this case the settings AUTOPRINT and AUT-
PRINT PC should be deselected.
AUTOPRINT (Data output, after having loaded the balance)
The setting AUTOPRINT is in the PRINTER-routine, and there it can be selected or deselected. When
AUTOPRINT is active the actual weighing value will be sent via the RS 232 interface when the balance has
been unloaded and then loaded after having achieved the stability.
AUTOPRINT PC (Continuous data output)
The setting AUTPRINT PC is in the PRINTER-routine, and there it can be selected or deselected. When
AUTOPRINT PC is active the actual weighing values will be sent continuously via the RS 232 interface.
Data output by transfer of remote controls
The following functions can be released by the remote controls that will be transferred as ASCII signs to the
balance.
t Tare.
w a weighing value (or unstable) is sent via RS 232 interface.
s a stable weighing value is sent via RS 232 interface.
If the balance receives the command w or s, it acts without printing delay.
Output on bar code printer
The data transfer mode has to be set on „Barcode".
As bar code printer a Zebra printer model LP2824 is provided.
Take into account that the output format of the balance is fixedly defined and cannot be changed.
The printer format is stored in the printer, i.e. in case of a failure the printer cannot be changed with a new
one from factory, previously it is necessary that KERN installs the respective software.
The Zebra printer and the balance must be connected to the delivered interface cable when they are
switched off.
After switching-on both appliances, and after reaching the status ready-for-operation, a label will be printed
out when pressing the
