SERIAL PORT INFO
SERIAL PORT MODES
DEMAND DUPLEX MODE
The Demand Duplex Mode provides a two-way serial transmission mode. In this mode,
the output information is transmitted on demand; either by pressing the PRINT key on
the indicator’s front panel or upon receiving a recognized command from a host device
(i.e. computer).
NOTE: Ensure that your cabling contains the proper handshaking.
CONTINUOUS DUPLEX MODE
The Continuous Duplex Mode provides a two-way serial transmission mode. In this
mode, the output information is transmitted continuously making it a popular choice for
remote displays and other remote devices requiring a constant data stream. The trans-
mission automatically occurs at the end of each display update. The indicator will react
upon receiving a recognized command from a host device.
RECOGNIZED HOST COMMANDS (applies to both demand and continuous duplex
modes)
“P”
- This command is sent to the indicator to print the indicated display. The indicator
will not respond if the scale is in motion, positive overload or negative overload.
“Z”
- This command is sent to the indicator to zero the scale. The indicator will not re-
spond if the scale is in motion, positive overload or negative overload. The indica-
tor will also not respond if it is not in gross mode or within the zero-range speci-
fied in F4 of the Setup Menu.
“T”
- This command is sent to the indicator to tare the scale. The indicator will not re-
spond if the scale is in motion, positive overload or negative overload. The indica-
tor will also not respond if it is displaying a negative gross value.
“G”
- This command is sent to the indicator to switch to gross mode. The indicator will
not respond if the scale is in motion, positive overload or negative overload.
“N”
- This command is sent to the indicator to revert to net. The indicator will not re-
spond if the scale is in motion, positive overload or negative overload. The indica-
tor will also not respond if a tare has yet to be established.
“C”
- This command is sent to the indicator to toggle among the configured units of
measure.
AUTO PRINT MODE
The Auto Print Mode provides a one-time serial transmission once a non-zero, stable
condition is achieved.
TEST AND MEASUREMENT MODE
The Test and Measurement Mode is identical to the Demand Duplex Mode with one ex-
ception: the indicator will respond to a PRINT command even when the scale is in mo-
tion, positive overload or negative overload.
