Tare Presetting via PC
The command for taring the device is ‘T0’ and it has the following format:
STX ADD
T
0
XXXXXX
BCS2
BCS1 ETX
XXXXXX, the tare weight, is the 6 digit required tare. For example (assuming no
decimal point), 000010=10kg tare; 000100=100kg tare.
If the scale is set to accuracy of 1 decimal point then 000010=1kg tare;
000100=10kg tare.
Separation of COM1 and COM2 Network Addresses
You can program a separate address for COM1, mainly for Alibi purposes but also for
other possible future uses. This is done by setting setup parameter
2.C
=65-90 (that is
A to Z) according to your requirements.
