aa is the two-character instrument address.
n is the argument defined below.
↵
is the 'carriage return' character (ASCII decimal 13).
Argument
"0" disables continuous transmission (default). The instrument will only transmit when
requested.
"1" enables continuous transmission of the front panel display. This is equivalent to
sending the system command "F0 Transmit Front Panel Display" repeatedly. The
instrument will respond to other commands normally.
"2" performs the system command "FL Transmit Multiple Readings" repeatedly. The
instrument will respond to other commands normally.
Examples
Sending “#00WI1
↵
“ will cause the instrument to transmit the front panel display
contents as quickly as possible. The instrument will reply with "OK" before
commencing transmissions.
Reply
"
OK
" or "
ERROR
".
Remarks
Some terminal emulator programs running under Microsoft Windows operating systems
(such as HyperTerminal) may appear to "lockup" the computer after enabling
continuous transmissions with baud rates greater than 2400 baud. This is because
Windows is so busy reading and displaying the received characters that it will not
accept keyboard or mouse input.
It is a bad idea to use continuous transmission with two-wire RS-485 communications.
