Display Filter Window Commands (DW)
The Display Filter Window (DW) command set enables and disables the filter window
and allows the user to enter the unit and value of the filter window to use. There are
two commands used to enable and set the filter windows. The format to enable or
disable the Filter Window is DW1(channel)(0 or 1) where channel is A or B, 1 enables
the window and 0 disables the window. The format to set the window unit and value is
DW2(channel)(window unit)(window value)# where window unit is the desired unit for
the filtering window, and window value is the desired value of the window. The units
available will depend on the sensor that is currently active for the channel. It is a good
idea to issue the @123? command and find out what the active sensor is on the
channel with the @123SA or @123SB commands to make sure that the appropriate
unit will be entered. The window must be enabled before a value can be entered.
Disabling the window sets this value to 0. The window, once enabled and set, will take
effect immediately and will remain in effect until the window is disabled.
Note that changing a cell type on a channel will automatically disable the filter window
for that channel, reset the units to Lb or LbI, and set the window value to 0. The
window must then be reset and re-enabled by the user.
Example:
@123DW1A1
Acknowledge:
@ 123 Filter Window A is On
Example:
@123DW2A000.0002#
Acknowledge:
@ 123 Filter Window A Unit = Lb
@ 123 Filter Window A = 0.0002 Lb
Display User Sums (DS)
The Display User Sums (DS) command is used to enable/disable and set up to four
different possible User Sum combinations. The format is DS(sum index)(Ch. A) (Ch. B)
(Ch. C) (Ch. D), where sum index is 1, 2, 3 or 4 dependent on which sum the user wishes
to edit and the selections for channels are either a 0 (don’t add) or a 1 (add). Thus you
can add or remove any combination of these channels with a single command up to four
times.
Example:
@123DS20101
Acknowledge:
@ 123 User sum 2: B+D
