11.4 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
( l e g a l - f o r- t r a d e s e r i a l s c a l e ) o r I N D U S T
(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 selected
p o r t a n d s e t t h e f o r m a t u n d e r t h e S F M T
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 11.6 for more information about stream
formatting and format identifiers.
iRev 4 provides several preset scale formats within its
Stream Formatting function. Figure 11-1 shows one of
the iRev 4 stream formatting displays.

11.5 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 4 to set the
Local Unit serial parameters shown in Table 11-7.
Configure the remote indicator using the serial
parameters listed for the Remote Unit.

EDP.INPUT#p CMD DISPLAY
EDP.STREAM#p DISPLAY KEYPAD

In the listed serial commands, p represents the serial port
number.
