Serial Scale Interface

Serial port 4 or the expansion port 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

720i

. 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 IND SC
(industrial serial scale).

2. Return to the SCALES menu. Under CONFIG,

drop down and use the

right

or

left

navigation

key to select the serial port (PORT 4 or PORT
7).

3. Use

Revolution III

to edit 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>

<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 11.5 for more information about stream
formatting and format identifiers.
