CONFIGURATION SETTINGS
The setup procedure is divided into four different sections,
displayed on four different folders inside the main window:
• General Options Setting (see “General Options Setting”)
• RS232 Options Setting (see “RS232 Options Settings”)
• RS485 Options Setting (see “RS485 Options Settings”)
• Digital I/O Options Setting (see “Digital I/O Options Set-
tings”)
Five buttons are available on the bottom of the window, which
can be pressed for performing the following actions:
“Update All” button:
Press this button to send the complete configuration to the
HI504901 device. It is possible to test all RS232 and RS485
devices for connection or not. In this way the HI504901 inter-
face can be configured even if devices will be connected only
on a second time to RS232, RS485 and digital input port.
If the PIN code is changed during configuration, it will be
checked and this operation lasts about 30 seconds. If no
error occurs, the message “HI504901 device correctly up-
dated!” will be displayed. Otherwise the occurred errors list
will be shown and the previous configuration will be kept in
HI504901 memory.
Note
If no error occurs during configuration, the previous
HI504901 setup will be lost. At start-up, 3 attempts for en-
tering the cellular PIN code are available (see “General op-
tions setting” section) and at each update with a wrong PIN
value, an attempt will be lost. The SMS’s stored in the SIM
card will be erased.
Note
If an error occurs on cellular phone before pressing the “Up-
date All” button, the cellular phone will be turned off and on
again for trying solving the error condition. This procedure
lasts about 30 seconds.

in the
HI504901 memory.

In the “Advanced Settings” section it is possible to give to the
modem connected to the PC a particular configuration for

which the modem is connected.
When “OK” is pressed, the software will try to establish a
data call between the PC and the
HI504901 device, and
then it is possible to proceed with the configuration (see “Con-
figuration Settings” section).

will be displayed by application software. Check if the mo-
dem line is busy, or
