The unit connected to the instrument (typically a personal computer) acts as a MASTER and is the only
unit that can start a process of communication.
The process of communication must be made by the transmission of a string by the MASTER, followed
by a reply from the SLAVE concerned.
CONTROLS FORMAT DESCRIPTION:
The double quotes enclose constant characters (observe upper and lower case); the < and > symbols
contain variable numeric fields. The <addr> is the instrument identification. In case of communication
on the RS485 port, is obtained by adding 80h to the instrument's address value (for example with ad-
dress 3 <addr> = 80h + 03h = 83h). In case of communication on the RS232 port, the <addr> must
always be equal to 81h, or, in case of communication on the Ethernet port, the <addr> must always
be equal to FFh
1.REQUEST FOR THE NET AND GROSS WEIGHT AND CURRENT PEAK
Master: <Addr> "N" EOT
DAT 400: "N" <Addr> <status> <net> <gross> <peak> ETX <chksum> EOT
2 EXECUTION WEIGHIN COMMAND
This command is only available in case of METRIC operation. The possible use conditions are:
• Stable weight.
• Since the last executed weigh, the weight has undergone a change of at least 20 divisions (delta
weight).
• Gross weight equal to or greater than the minimum weight (minimum of 20 divisions) and less than
the maximum capacity.
• Net weight not null. Between two successive requests, the weight must have a variation of 20 divi-
sions; if the weight is unstable the command is not executed.
