SHORT MESSAGING SERVICE (SMS)

It is possible to connect the Hanna HI 504900 GSM mod-
ule to the RS485 port of the instrument. This connection enables
the instrument to send SMSs to one (or two) cellular phone(s)
and through this feature the device can be monitored at ev-
ery moment. Moreover if an error occurs on the HI 504, it is
possible to have an SMS sent to the cellular phone(s) advis-
ing immediately the user about the problem.
To use the SMS feature, a SIM card able to make voice
calls must be used.
The SMS feature can be enabled through the setup item P .00
by selecting "CELL" for cellular module connection instead of
"PC" connection.
Before enabling this feature it is necessary to enter the PIN of
the SIM card of the GSM module (setup item P .01) and one
or two phone numbers associated with the service (setup items
P .02 and P .03) to which the messages will be sent.
The phone numbers have to be inserted using the interna-
tional format excluding the starting "+" character and without
any space inside the number. For example if the cellular num-
ber is "+39123456789" (+39 is the country code), the
number to be stored in the HI 504 is "39123456789".
When the item P .02 (or P .03) is selected,
the primary display will show the first
four digits of the correspondent phone
number. A minus sign is added in the
front of the number to indicate that the
first four digits are shown and the first digit will blink to indi-
cate the possibility to modify the value.
The user can select the desired digit using the æ or
Note
"-" character indicates that the digit is not used (leave dashes
on the right of the number).
