4.1.2 Serial Command Configuration
The serial command set can be used to configure the
920i indicator using either a personal computer,
terminal, or remote keyboard. Like iRev , serial
command configuration sends commands to the
indicator serial port; unlike
iRev , serial commands can
be sent using any external device capable of sending
ASCII characters over a serial connection.
Serial commands duplicate the functions available
using the indicator front panel and provide some
functions not otherwise available. Serial commands
can be used to simulate pressing front panel keys, to
configure the indicator, or to dump lists of parameter
settings.
4.1.3 Front Panel Configuration
Use the CONFIG submenu under the SCALES menu
to configure A/D scales. For example, in an indicator
with a single-channel A/D card installed in Slot 1, the
Scale Configuration display will show the A/D listed
(
Slot 1 Channel 1 ) under the AVAILABLE A/D’s column. Use
the left navigation key to select the A/D, then press the
center softkey, Add . The A/D is then moved to the
Associated A/D’s column. If no other A/D’s are listed
in the
AVAILABLE A/D’s column, the center softkey
changes to Done , as shown in Figure 4-2. Press Done to
exit the Scale Configuration display..

4.1.4 Total Scale Configuration
The output of two or more A/D scales or iQUBE
systems can be configured to function as a total scale.
Once configured and calibrated, the total scale can be
sued as a source for other system functions, including
streaming, setpoints, print formatting, and analog
output.
To set up a total scale from the indicator front panel,
use the scale configuration display (see Figure 4-2) to
select the A/D scales or
iQUBE systems to configure as
a total scale. (Use the Change Type softkey to show
available A/D scales or iQUBE systems; use the right
navigation key to select the total scale sources.) In
iRev , assign the total scale to an unused position then
select source scales from the existing A/D scales or
iQUBE systems.
The FORMAT configuration of the total scale (see
Figure 4-5 on page 28) should match that of the source
scales. However, the value specified for the total scale
GRADS parameter should be specified as the sum of
the GRADS values for the source scales. For example:
if SCALE 1 is set to GRADS=10000, SCALE 2 to
GRADS=5000, SCALE 3 (the total scale) should be set
to 15000 grads.
The total scale will show an overrange indication if the
maximum capacity of any source scale is exceeded,
and show dashes if any source scale reads a negative
value. Source scales will respond to Tare and Zero
operations performed on the total scale.
