6.3 Output
Types
6.3.1
Local Printer
Works with port 1. A slip is printed on the printer connected to the port each time the
user presses
( ). The following print formats are available:
Ten standard print formats (see section 6.4).
Two custom print formats (see section 6.5).
6.3.2
Continuous Weight Output
Works with ports 1 and 2 (RS232 or RS485). Net weight and status information is
transmitted continuously. No handshake is required. Used mainly for remote display
or PC. The structure of the transmitted data block is shown below. There are 2
Continuous Weight Output selectable (parameters

and
3.6
) formats LEO and AND
(AND protocol is supported only by Scale 1).
