When all information can not be sent with one SMS (the
maximum number of characters for an SMS is 160), it will be
sent more than one message, each one beginning with the
label “Info#p/#t:” which gives the indication of the progres-
sive information SMS number (#p) and the total number of
information SMSs (#t) that are going to be sent for the cur-
rent instrument.
Find here below a complete list of available information (and
coded notations) for all devices which can communicate with
the HI504901 interface.

tem-halted;

active alarm in the system;

• “ECn: ##.#”: indicated values by conductivity sensors
(1, 2 and 3);
• “SR: ####”: indicated value by solar radiation sensor;
• “IrPRG: ##”: number of the active irrigation program; if

All these information will be reported in two SMSs; if some alarm
is active in HI8001 or HI8002 controller, a third SMS will be
sent, with the label “INFO3/3”. This message will contain the
got from the controlled instruments, and could be requested,
for example, after an alarm message regarding an error which
should close without any intervention. The user could also want
to be informed about the values of the measured magnitudes
or current devices status.
The information messages can be requested:
1. by making a call from one of the phone numbers programmed
for alarm messages sending: in this case the cellular phone
interface recognizes the calling phone number, hangs up
without answering and then sends to the calling number
one (or more) information message(s) for each controlled
instrument;
2. by sending an SMS from whatever cellular phone to the
device. The message must have the following format:
“P
the uppercase P letter followed by the cellular phone inter-
face password in uppercase letters; if the password is
disabled, just “P” is enough. Upon this requesting mes-
sage, the interface will send one (or more) information
message(s) for each controlled instrument to the cellular
phone which issued the requesting SMS.
The format of the information messages is very similar to the
one for alarm messages. The only difference is the “Info:
instead of “Alarms:
The format of information messages for the instruments con-
nected to the RS232 ports will be:

while of information messages for the instruments connected
to the RS485 ports will be:
