13.1 KERN Communications Protocol
KCP is a standardized set of interface commands for KERN scales enabling to display many
parameters and functions of the device and to control them. Thanks to it, KERN devices with
KCP may be easily connected to a computer, industrial control systems and other digital sys-
tems. The detailed description can be found in the KERN Communication Protocol manual,
available in the Downloads tab on the home page of KERN (www.kern-sohn.com
).
To activate KCP, follow the description in the menu overview in the manual for a given scale.
KCP is based on ordinary commands and responses in ASCII format. Every interaction is
composed of a command or arguments separated by spaces and is finished with <CR>< LF>
commands.
KCP commands supported by the scale may be displayed by sending an inquiry composed
of “I0” command and CR LF commands.
The list of most often use KCP commands:
