F4.1 Continuous Data Format
Selects the data format used for continuous data output. Normally used for remote
displays and scoreboards and in some computer applications. This data is available from
TB2 of the mother board and from channel 2 (continuous) of the “DDO” (dual-data
output) option board which, if installed, is connected to J6. Note, that if both demand and
continuous data are used the data on TB2 will contain both data streams and may cause
errors. Therefore, if both demand and continuous data are to be used it is recommended
that they both be connected to the “DDO” board. If this function is not used, disable it as
it will slow down the system.
F4.2 Weight Change Percentage
Used with the auto-print function in F4.0. Specifies the percentage of change based on
full capacity (as set in the calibration procedure (F6)) necessary to rearm the auto-print.
For example, if your scale has a capacity of 100,000 lb and F4.2 is set to 15%, a weight
change of 15,000 lb would be required to rearm the auto-print.
F4.3 Minimum Print
Used with the auto-print function in F4.0. Sets the number of increments (as set in F6.1
and F6.2) above zero required before the auto-print is allowed to function. For example,
if F6.1 is set to 20 and F6.2 is set to “0” and F4.3 is set to “30” then the auto-print will
not operate until the weight on the scale exceeds 600 lb. This would be useful on a truck
scale to prevent prints occurring when people walk across the scale.
F4.4 Bi-Directional Communications
Any function that can be performed from the keyboard can be performed through the bi-
directional interface. Connection to this interface is provided on TB2 on the mother board
(in current loop) If a current loop device is not available and RS232 is needed then a
“DDO” option board must be installed and connected to J6 on the mother board and the
built in current loop input port must be disabled by cutting JP1 located just below J3 and
to the left of J6 on the mother board. The response rate on this function is very low. Send
the data as slowly as possible to avoid errors. Disable this function if not used, as it may
pick up random noise.
F4.5 Weight Data Format
Controls the way weight data is sent out to the serial ports. Setting “0” {Displayed weight
only} will send whatever weight is currently displayed whether it be gross or net. Setting
“1” {Single line gross/tare/net} will send a gross/tare/net string with only one (1) CR/LF
at the end. If the display is in the net mode, this will put all three (3) items on one (1) line
(if there is room. See printer for more information). Setting “2” {Multiple line
gross/tare/net} will send a gross/tare/net string with a CR/LF after each item. If the
display is in the net mode, this will put each item on its own line. Setting “3” {Status
