or the factory. To prevent the problem, try
reducing the baud rate (P200).
tx on hold This will occur if a data transmission is held up
for two seconds of more due to a de-asserted
handshake. Refer to the description of
parameter P206 in the technical reference
manual for more information.
tx abort This occurs if the [CLR] key is pressed when
the tx on hold error message is shown or if P206
is set for abort and the transmit buffer becomes
full.
tx con'd This will appear briefly when the handshake is
re-asserted after the tx on hold message occurs.

HOOTING
DATA TRANSMISSION: If a data transmission of any weight-related
numeric data such as Gross, Net or Tare is sent as dashes, an overload or
underload (negative overload) condition was in effect. Remove the cause of
the overload (or underload) and repeat the transmission. Also check the
setup of parameters P204 and P206.
DISPLAYED WEIGHT: If an overload or underload occurs due to an
electrical overstress (EOS) normally due to lightning or ESD discharge, then
press the [CLR] key. The message wait 1 will appear for about 1 second.
The A/D converter will then be reset and the system should again be
functional. If not, power down for a few seconds. If the indicator still does
not work properly after power-up, check the load cell or platform wiring. If
okay, permanent damage may have occurred, most likely to the instrument
amplifier.
