Kern Communications Protocol (Kern Interface Protocol) - KERN EWJ Operating Instructions Manual

15.4 KERN Communications Protocol (KERN Interface Protocol)

KCP is a standardized set of interface orders for KERN balances, which allows many
parameters and device functions to be called up and controlled. KERN devices that
have KCP can use it to connect easily to computers, industrial control systems and
other digital systems. A detailed description you will find in the „KERN Communica-
tions Protocol" manual, available in the download area on our KERN homepage
(www.kern-sohn.com).
To activate KCP please observe the menu overview of your balance's operating in-
structions.
KCP is based on simple ASCII orders and replies. Every interaction consists of an or-
der, possibly with arguments separated by spaces and finished by <CR>< LF>.
The KCP orders supported by your balance may be queried emitting the order „I0"
followed by CR LF.
Extract of the mostly used KCP orders:
