FL Transmit Multiple Readings
Purpose Transmit a set of multiple readings as defined with the "WL" command
Usage #aa FL ↵”
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
↵ is the 'carriage return' character (ASCII decimal 13).
Example Suppose that the command “#00WL01110212 ↵“ has been previously sent. Sending
“#00FL ↵“ might result in a reply of “-001.2, 0051.3, 000.05, 100.31↵”
Reply A series of ASCll-floating-point values, separated by the 'comma' character (decimal 44).
Remarks See "RL/WL Read/Write Multiple Readings Setup" for more information.
The format of each transmitted reading is the one that would be used to display the
readings on the front panel. Because some types of channels (such as Relay Output
channels) do not acquire or calculate data, the data read from these channels will be zero.
See "WI Write Continuous Transmit Setting" for information on how to execute this
command as quickly as possible.
FR Reset
Purpose Resets the instrument as if the power switch had been toggled
Usage “aa FR ↵”
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address,
↵ is the 'carriage return' character (ASCII decimal 13).
Example “00FR ↵”
Reply none
Remarks
"Do not pass 'GO!' Do not collect $200." -Monopoly
W1 Write Baud Rate
Purpose Writes a new baud rate for serial communications
Usage “aa
W 1 n ↵”
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
n may be 300,600,1200,2400, 4800,9600,19200 or 38400.
↵ is the 'carriage return' character (ASCII decimal 13).
Example Sending “#00W138400 ↵” will cause the instrument to communicate at 38400 baud. The
instrument will reply with “OK” at this new baud rate.
Reply “OK” (at new baud rate) or “ERROR" (at present baud rate).
Remarks
As shipped from the factory, DFI instruments are set to communicate at 9600 baud.
To determine what baud rate the instrument is using from the front panel:
1) Enter the setup menus by pressing [UP] and [DOWN] together. The display will read
“
SETUP ” and then “ CHANNEL 01 MENU ” (which is the top-most item on the setup menus).
2) Press and release [DOWN] until the display reads “
SERIAL COM. MENU ” Press
[ENTER] to enter the SERIAL COM. menu.
3) Press and release [DOWN] until the display reads “
BAUD RATE ". Press [ENTER] and
the display will show the baud rate. The baud rate cannot be changed from the front
panel, only from the serial port.
4) Press [EXIT] to exit the menus and restart the instrument.
W2 Write Automatic Line-feed Setting
Purpose Enables or disables use of the line-feed character (ASCII decimal 10) in replies.
Usage “aa W2 n ↵”
#is the 'pound' or 'hash' character (ASCII decimal 35).
