INTERFACE CONFIGURATION
The HI504903 supervisor is not provided with keyboard or
display for user interfacing purpose. For first installation and for
successive changes of the system configuration, it is necessary
to use the HI504903SW Windows
® compatible application
software provided with the instrument.
APPLICATION SOFTWARE INSTALLATION
To install the HI504903 configuration software on the com-
puter, it is necessary a 3.5’’ drive. Insert the disk in the floppy
disk driver, execute setup.exe and then follow on-line in-
structions.
After installation, run the configuration software by simply
double-clicking on HI504903SW icon and starting the con-
figuration procedure.
STARTING CONFIGURATION
Before starting the configuration procedure, turn the
HI504903 on and make sure it ended the initialization pro-
cedure (see “Start-up” section).
The HI504903 supervisor can be configured in two different
ways: “Local configuration” and “Remote configuration”,
which can be selected on “Connection setting” window while
running the application software.
Find here below a complete list of LED’s status during con-
figuration procedure:

SMS sending by the interface.
SMS can be submitted by the HI504903 supervisor only if
the SMS sending feature is enabled through an external switch
(see further on for details); if the SMS sending is disabled,
then no message will be sent upon alarm or fault condition
on connected devices.
Note To make the HI504903 queries the connected devices and
sends SMS’s, it is necessary to configure the interface, other-
wise no polling procedure can take place and no alarm no-
tification will be given by the interface. HI504903 can not
automatically detect which instruments are connected to the
interface; moreover, the user must select for which type of
alarms the warning SMSs have to be sent.
While in idle state, the SMS sending feature can be disabled
or enabled by the user at any time, by simply closing (or
opening) the proper external switch. If no error indication is
already active, then the red and green LED’s (#3 and #4 on
page 9) keep indication about the SMS sending enable/dis-
able status:
Note Sometimes the updating of LED indication about SMS send-
ing status can take a few seconds after changing the external
switch status by the user. This happens if the interface is busy
while performing procedures as polling devices, SMS send-
ing, incoming call processing, etc.
While in idle state, HI504903 can serve also incoming re-
quest for configuration or PC communication session
activation (both local and remote), but remote sessions (both
configuration and PC communication) can take place only if
no cellular errors are active on the interface.
External Switch LED Status Meaning
Open SMS enable (green) ON SMS sending enabled
SMS disable (red) OFF
Close SMS enable (green) OFF SMS sending disabled
SMS disable (red) ON
