SMS DELIVERY
HI504901 is able to send SMSs to one (or two) cellular
phone number(s). HI504901 can send two types of mes-
sage: alarm SMSs (upon an alarm condition at least in one
of the instruments connected to the interface) and informa-
tion SMS (upon specific request from the user).
Note To use the SMS feature, a SIM card able to make a voice call
must be used.
ALARM SMSs
Alarm messages are submitted by HI504901 to the cellular
phone number(s) when an error occurred on one of the instru-
ments connected to the interface. A message about an alarm
condition in one instrument will be sent by the interface only if
the alarm is active and the specific alarm notification was en-
abled during last configuration, by checking the proper box on
the “message option” window of the selected device (see “Inter-
face configuration” section). If an alarm is active in one
instrument connected to the interface but its notification was not
enabled during last configuration, then no SMS will be sent
(however HI504901 gives indication to the user about the
error condition by turning on the red LED for the RS232 chan-
nel or RS485 port or digital input port where the instrument is
connected).
Note An alarm SMS can be sent only if SMS sending is user en-
abled through digital input terminal (#8 on page 8), other-
wise no SMS will be issued.
The format of alarm messages for instruments connected to the
RS232 ports will be:
“; RS232-CHANNEL>; Alarms: MENT>; Rem msg: MESSAGES>”
The format of alarm messages for instruments connected to the
RS485 port will be:
“; RS485-DRESS>; Alarms: ;
Rem msg: ”
