62 920i Installation Manual
5.6 Connecting to the Indicator
Connect the PC serial port to port 2 of the 920i. Return
to the Hardware Configuration display, then click on
the
Connect icon in the toolbar. iRev 4 attempts to
establish communications to the indicator.
Once communications is established, iRev 4 queries the
indicator configuration to determine whether the
indicator hardware matches the virtual hardware
configured in the current iRev 4 file. If the hardware
matches, the Hardware Configuration section of iRev 4
is disabled, preventing further changes.
If the hardware does not match, you are given the option
of either canceling the connect operation or overwriting
the iRev 4 hardware configuration with the actual
indicator hardware configuration.
5.6.1 Downloading to the Indicator
The Download Configuration function on the iRev 4
Communications menu allows an iRev 4 configuration
file (with or without scale calibration data), setpoint
data, widgets, database tables, or an iRite program file
to be downloaded to a connected indicator in setup
mode.
T h e D o w n l o a d C u r r e n t D i s p l a y f u n c t i o n o n t h e
Communications menu allows you to download only
the currently displayed object, such as the parameter
set for one scale of a multi-scale configuration.
Because less data is transferred using Download Current
Display , it is typically faster than a full configuration
download, but there is an increased possibility that the
download may fail due to dependencies on other
objects. If the download fails, try performing a
complete download using the
Download Configuration
function .
A progress message is displayed during the download
indicating the progress of the download and also during
the clear memory indicating its progress.
5.6.2 Uploading Configuration to iRev
The Upl o ad C o nfi g uration function on the iRev 4
C o m m u n i c a t i o n s m e n u a l l o w s t h e e x i s t i n g
configuration of a connected indicator to be saved to a
file on the PC. Once saved, the configuration file
provides a backup that can be quickly restored to the
indicator if needed. Or, the file can be edited within
iRev 4, then downloaded back to the indicator.
NOTE: The indicator must be in setup mode before
uploading or downloading data.
5.7 Installing Software Upgrades
This section applies only to 920i units using a serial
board, not a USB board.
New releases of the 920i system software can be
downloaded and installed using an Internet connection
and the Rice Lake Web Update application.
NOTE: Before upgrading to a new version of 920i system
software, ensure that a copy of the current indicator
configuration has been saved using iRev 4. Reloading the
system software requires a RESETCONFIGURATION
function and resets all configuration and calibration values
to their factory defaults.
