Scale with
Eltron
protocol sending record of data after pressed
key.
The scale sends following information: number of label, date and time (if clock
module is installed ) and weighing result. During transmission communicate Label
is displayed.
In special features scale can be equipped in second RS232 interface for additional
functions, ex. continuous transmitting of indications to second display.
Computer must have a special program for cooperation with data from a scale.
Programs offer is available on

Attention:
Network number different than zero (F..-rS
/ nr
function) changes scale working
mode: communication with a computer is possible after logging the scale in with
02h scale number command. To log the scale out use 03h command.
For example: Using a program to test RS232 interface ( program is available on
www.axis.pl
in computer programs section) for scale number 1 please write:
$0201
to log in, then
SI
, and write:
$03
to close communication
.
