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

See Section 10.5 for information about stream
formatting and format identiÞers.

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 be 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 92 lists the format identiÞers used
to conÞgure a custom stream format. See Section 10.6
on page 94 for e
xamples of custom stream formats.
