10.3 PS/2 Keyboard Interface
Serial port 2 on the
920i
CPU board provides a
PS/2-type keyboard interface for use with a remote
keyboard. To use the keyboard interface, set the
INPUT parameter for Port 2 (under the SERIAL
menu) to
KEYBD
.
Table 10-5 summarizes the
920i
-speciÞc functions
provided by the keyboard interface; most other
alphanumeric and navigational keys provide functions
equivalent to those typical for PC operation.
NOTE:
The keyboard interface is not hot-pluggable.
Disconnect power to the
920i
before plugging the
keyboard cable into the Port 2 connector.
10.4 Serial Scale Interface
Serial ports 3 through 32 can be conÞgured 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 conÞgured to
accept scale data, the data format can be customized
to match the data stream sent by that indicator.
To conÞgure a serial scale, do the following:
1. Under the SERIAL menu, set the INPUT
parameter for the selected port to 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 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 bits of net data with decimal point
<M> Mode
<U> Units
<S> Status
<CR> Carriage return
<LF> Line feed
iRev
provides several preset scale formats within its
Stream Formatting function. Figure 10-1 shows one of
the
iRev
stream formatting displays.

10.5 Custom Stream Formatting
Each port can b e independently conÞgured to stream
a default frame format or can be customized to stream
a user-deÞned format. Custom formatting is very
similar to the standard print formatting described in
Section 6.0. Table 10-6 on page 86 lists the format
identiÞers used to conÞgure a custom print format.
