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 ON/PRINT key
on the instrument’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 instrument will re-
act 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 instrument to print the indicated display.
“Z”
- This command is sent to the instrument to zero the instrument.
“C”
- This command is sent to the instrument 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.
