In the continuous print mode, any messages that appear in the display, including
error messages such as "UnAbLE", will be transmitted over the RS-232.
The continuous print mode always transmits "string format," regardless of which print
format is selected.
Note: When using the continuous print mode, it is recommended that the baud rate
be set at 2400 or higher to ensure that the all scale output can be transmitted.
If the baud rate is set too low, the internal output buffer in the scale may
overflow, causing a “Q-out oflo” error message to be transmitted. Conversely,
if commands are sent too fast, the scale will not process them which will cause
a “Q-in oflo” error. However, since the scale can buffer 256 input characters,
the probability of encountering this error is small.
The Jump Function
The jump function causes the scale to immediately operate in a given weight unit.
Using this function assures that numbers, such as tare weight or average piece
weight, entered through the RS-232 interface are interpreted in the correct units. For
example, if the average piece weight was stored by a computer in grams, it would be
necessary to ensure that the scale was operating in grams prior to sending the APW
to the scale. This feature is only available through the RS-232 interface.
To use the jump function, send the characters "nJ" to the scale. Where "J" is the jump
function command and "n" is the unit code. The units code ranges from 0 to 7 as
shown below:
Units Code Unit
0 X units
1 grams
2 ounces
3 pounds
4 troy ounces
5 pennyweights
6 carats
7 T units (tamperproof units)
Do not send any number other than 0-7.
For example, to enter an average piece weight of 0.23456 grams from a computer,
send "1J0.23456A". The "1J" sets the scale for operation in grams. The "0.23456A"
tells the scale to enter that weight into the APW register.
The jump function prevents misinterpretation of values entered from a computer.
