10.4 Serial Scale Interface
Serial ports 3 through 32 can be configured for serial
scale input. The serial scale function allows other
scale indicators to send gross, net, or tare weight data
to the
920i
. Once a serial port has been configured to
accept scale data, the data format can be customized
to match the data stream sent by that indicator.
To configure a serial scale, do the following:
1. Under the SERIAL menu, set the INPUT
parameter for the selected port to SCALE
(legal-for-trade serial scale) or INDUST
(industrial serial scale).
2. Return to the SCALES menu. Under CONFIG,
drop down and select the serial port. If the serial
scale is not shown, press the
Change Type
softkey to select available serial scales, then use
the navigational keys to select the serial scale.
Press
Add
to move the scale to the righthand
column, the press
Done
.
3. Under the SERIAL menu, return to the se lected
port and set the format under the SFMT
parameter to match the format sent by the serial
scale.
The default serial scale format is:
<2><P><W7.><U><M><S><CR><LF>
where:
<2> STX character
<P> Polarity
<W7.> Seven characters of net data with decimal point
<M> Mode
<U> Units
<S> Status
<CR> Carriage return
<LF> Line feed
NOTE:
Industrial serial scales (INDUST) do not require
the <M> , <U> , and <S> identifiers. However, the units and
number of decimal places must be specified. Units can
be selected from the FORMAT menu; decimal places
should be indicated on the w-spec identifier. For
example, a seven-digit weight requiring two decimal
places should be specified as <W7.2> rather than <W7.> .
See Section 10.6 for more information about stream
formatting and format identifiers.
iRev
provides several preset scale formats within its
Stream Formatting function. Figure 10-1 shows one of
the
iRev
stream formatting displays.

10.5 Local/Remote Operation
For truck scale and similar applications, local/remote
support provides function equivalent to that of a
legal-for-trade remote display with keypad. Scale data
from the local indicator is also displayed at the remote
unit, and keypad input from the remote allows transactions
to be initiated from either the local or remote unit.
To configure for local/remote operation, first set up
the local scale (including softkey assignments, truck
mode, and database information, as required). Use the
SERIAL menu, serial commands, or
iRev
to set the
Local Unit serial parameters shown in Table 10-7.
Configure the remote indicator using the serial
parameters listed for the Remote Unit.
Serial
Configuration Parameter
Parameter Value
Local Unit Remote Unit
EDP.INPUT#p CMD DISPLAY
EDP.STREAM#p DISPLAY KEYPAD
EDP.BAUD#p 115200 preferred; local and
remote values must match
EDP.ECHO#p OFF OFF
EDP.RESPONSE#p ON ON
In the listed serial commands, p represents the serial port
number.
