Connecting a computer or a printer (optional)
The scale is equipped with RS232C or
RS485 (optional), which can be used to
connect external devices such as a computer
or a printer. Detailed way of communication
data is defined by one of protocol:
-
LonG
– protocol to printer and computer
-
ELtron
– protocol to label printer
When cooperating with a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample.
When protocol
Long
is chose scale sends
result of weighting on an initialize signal
from computer, or after pressed a
key.
When automatic transmission mode is chose
(function
LPt
), a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample. The scale sends
following information: successive number of
weighing, date and time (if clock module is
installed )and weighing result. During
transmission communicate Print is displayed
.
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. continues transmit of indicate to second display.
Computer must have a special program for cooperation with a data from a scale.
This programs are procurement by Axis.
