Appendix A • Super II 104
To use the Jump Function, send an 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:
Units Code Unit
0 User programmable unit (default GRAINS)
1 GRAMS
2 OZ (ounces)
3 LBS (pounds)
4 TROY (troy ounces)
5 DWT (pennyweights)
6 CARATS
7KG
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.
The Quantity Function
The Quantity Function operates very much like the “jump function” for the APW. By sending a numeric
value followed by the letter Q, the scale will then accept the APW that follows as the average piece weight
of the specified number of pieces represented by the numeric value preceding Q. For example, to send
1.2345 lbs as the APW of 1000 pieces, the scale needs to receive “3J1000Q1.2345A” (the 3J to specify the lb
units, 1000Q to specify 1000 quantity, and 1.23454A to specify the APW value).
An APW with a “Q” quantity can be entered with the scale in any APW Quantity mode but will only be
displayed in the entered quantity if the scale is set to the “APW Variable Quantity Mode”.
The Verify Function
When many scales or other peripherals are connected to a computer, it is sometimes useful for the com-
puter to be able to check on the status of these devices. The verify function can be used to determine the
model number of a scale and determine that the scale is functioning correctly. To invoke the verify func-
tion, transmit an ASCII “V”. If the scale is functioning correctly, it will send out the following messages
followed by carriage return and line feed:
“Model 409
Base 1 capacity XXXXX”
Status After Power is Applied
All Setra scales have an internal nonvolatile memory for storing certain status information. This memory
does not erase when power is removed from the unit. All setup functions (such as print format, minimum
pieces, minimum accuracy, baud rate, and data base information) are stored in this memory. As a result, the
baud rate and print format will not need to be reset each time the scale is turned on.
During the first 30 seconds of operation, the scale will run through a self-diagnostic procedure. When the
unit is ready to be used, it will identify itself by transmitting a “wake-up” message. (This message can also
be invoked by sending a “W” to the scale.)
