In the “Advanced Settings” section it is possible to give to the
modem connected to the PC a particular configuration for
the initialization string and the dial string. Note that in the
most common cases the default setting can be used. On
“Serial Communication Port” section select the COM port to
which the modem is connected.
When “OK” is pressed, the software will try to establish a
data call between the PC and the HI504903 device, and
then it is possible to proceed with the configuration (see “Con-
figuration Settings” section).
Note If no answer is received from HI504903, an alarm window
will be displayed by application software. Check if the mo-
dem line is busy, or HI504903 is busy (a remote configura-
tion or a remote connection or a polling procedure are tak-
ing place), or HI504903 cellular phone is over coverage.
Try later for a new remote configuration attempt.
LOCAL CONFIGURATION
The “Local” configuration is the only one allowed for the first
configuration of HI504903 supervisor. This type of configu-
ration takes place between the HI504903 device and a PC
(placed near) with HI504903SW installed, through a serial
cable connection.
To connect the HI504903 supervisor to the PC, use an
HI920010 cable. Plug one connector to the HI504903
device RS232 auxiliary connector (PC config port) and the
other one to a serial port of the PC. Before connecting the
supervisor to the PC, read the computer manual.
To proceed with local configuration, select the “Local” con-
nection type on HI504903SW “Configuration Settings”
window, and on “Serial communication port” section the PC
COM port to which the serial cable is connected. Then press
“OK” to proceed (see “General Settings” section).
Note The first configuration of HI504903 must be done through
a local configuration because it is necessary to set up the
SIM card PIN code and at least one cellular phone number
for the alarm SMS sending.
Note If no answer is received from HI504903, an alarm window
will be displayed by the application software. Check if the
serial cable is correctly connected or if the HI504903 is
busy (a remote configuration or a remote connection or a
polling procedure are taking place). Try later for a new local
configuration attempt.
REMOTE CONFIGURATION
The “Remote” configuration takes place between the
HI504903 device and a PC with HI504903SW software
installed, through a data call made by a modem connected
to the PC. In this way all HI504903 parameters can be re-
configured (excluding the SIM card PIN number), even if the
supervisor is located far from the PC, without requiring to
move the PC where the HI504903 is physically installed to
make a local configuration through serial cable (see “Local
Configuration” section).
To proceed with the remote configuration, select the “Remote”
connection type on HI504903SW, by checking the proper
box. On “HI 504903 phone number” field enter the phone
number of the SIM card inserted in the HI504903 and the
password (only if it was set in a previous configuration).
