ID REFERENCE COMMANDS
“RT” (RECALL TARE REGISTER COMMAND)
This sequence requests the CW-80 to Recall the Over/Under/Tare/Units
values associated with the ID number located in the Location character field,
and make these new values the current operating Over/Under/Tare/Units
values. The CW-80 acknowledges with a “*” (ASCII 2A Hex), when
successful.
“XT” (XMIT TARE COMMAND)
This sequence requests the CW-80 to Transmit the tare value associated
with the ID number located in the Location character field. It does not make
this Tare value the current tare value. It is simply used for inspection. The
CW-80 responds with the following format:
