Immediate And Continuous Print Modes - Setra Systems L Series User Manual

"c3" is the stability character. When a " " (space) is transmitted, the reading is not stable.
When an "S" is transmitted, the reading is stable. This corresponds to the "OK" symbol
on the display.
The string output is always terminated by a carriage return and line feed.
The following are some examples of string output:
+12.3456 PS
+0.846 IO
UNABLE
If a sample number has been entered, it will be transmitted during any print sequence.
For example:
+12345.6
04-10-92

IMMEDIATE AND CONTINUOUS PRINT MODES

Two types of output modes are available on Setra balances: immediate and continu-
ous print modes.
The immediate mode is invoked by transmitting a "P" over the RS-232 or by pressing
print on the keyboard. In this mode, the contents of the display is transmitted when
"string format" is selected. The print command may follow another command or series
of commands. For example, if " • %P" was transmitted; or the sequence, • , %, print was
pressed, the balance would send the contents of the APW (aggregate percent weight)
register. Using this mode, a computer can read data from the balance only when
specifically requested.
Continuous print mode will print the contents of the display at a specified time interval.
The rate at which data is output is variable from once every .2 seconds and up.This mode
is initiated by sending ".2P" over the RS-232, or by pressing • , 2 then print on the
keyboard. For longer time intervals, press or send the desired time interval followed by
P or the print key. This mode is cancelled by sending "— P' or pressing — then print
on the balance keyboard.
When using the continuous print mode, any other messages that appear on the display,
including error messages such as "UnAbLE", would also be transmitted over the RS-
232.
NOTE: When using continuous print mode, it is recommended that the baud rate
be set at 1200 or above to insure that all the balance output can be
transmitted. If the baud rate is set too low, the internal output buffer in the
balance may overflow, causing a "Q-out oflo" error message to be
transmitted. Conversely, if commands are sent at too fast a rate for the
balance to process them, a "Q-in-oflo" error may be caused. However,
since the balance can buffer 256 input characters, the probability of
means that the weight is 12.3456 lbs. stable
