RS485 OPTIONS SETTING
In this section it is possible to set all options related to the
RS485 communication channel towards the connected
HI142
temperature dataloggers. All the loggers must be connected
to the same RS485 bus; the maximum number of instruments
that can be connected to the same
HI504903
interface is 31.
To set the
HI142
options, click on one of the 31 available
buttons and then set the following features:
• Instrument name: enable the communication between
HI504903
interface and
HI142
temperature datalogger
connected to the RS485 channel by selecting “HI142” in
the window. To disable an instrument previously inserted,
select “NO INSTRUMENT”.
• Baud rate: once the instrument has been selected, the de-
fault baud rate value is automatically proposed. The only
baud rate available for
HI142
loggers is 1200 bps.
• Serial number: it is the serial number of the
HI142
logger
to be connected to
HI504903
(allowed values are within
0 to 999999 range). This serial number will be used by
HI504903
as logger address to identify the instruments
connected to the RS485 channel. Each logger must have a
different value for this field.
Note
To enable one
HI142
logger, all the three previous options
(instrument name, baud rate and serial number) must be set.
• Messages options: to choose in which alarm conditions an
SMS will be sent to the selected phone number(s), click on
the “Message Options” button. This window will be dis-
played only if “HI142” was selected on “Instrument name”
field. Available alarm conditions for
HI142
are:
• Temperature out of range: to receive an alarm SMS when
temperature on
HI142
logger exceed low or high tem-
perature limits.
• Low battery: to receive an alarm SMS when the level of the
logger internal battery is low;
contact the nearest
Hanna Service Center.
DIGITAL I/O OPTIONS SETTING
Digital input section
This section includes all the specific options that apply to the
digital input channel. This channel is intended for connec-
tion to a simple instrument provided with a digital output
port. For such instruments, an alarm output like an electro-
Security options:
• On “HI504903 Password” field it is possible to set the pass-
word for the
HI504903
device. This password protects from
unauthorized remote modem connection to one of the instru-
ments connected to the cellular phone interface and from
unauthorized remote configuration. This password does not
block the local configuration of the instrument, i.e. no pass-
word is required to configure the
HI504903
device with its
application software through the serial cable. The password
can be disabled. Valid values are string of 6 to 20 characters
(letters and numbers are allowed).
Note
Letters typed in lower case will be automatically changed in
upper case by the software. If the field is enabled, a value
must be inserted.
• On “PIN number” field the SIM card PIN number has to
be inserted (maximum 4 digits). When inserting this code
the characters are masked. Valid values are numbers from
0000 to 9999. The PIN code must be inserted only in the
first
HI504903
configuration and every time the SIM card
PIN code is changed.
Note
The SIM card PIN number must be inserted in any case and
is required by the application software even if the PIN lock
has been disabled through a normal cellular phone.
Note
If an update with a wrong PIN code is made, an attempt for
cellular PIN insertion is lost. At start-up, 3 attempts for en-
tering the cellular PIN code are available, and at each up-
date with a wrong PIN value, an attempt will be lost. After 3
wrong attempts, to unlock the SIM card, extract it and manu-
ally enter the PUK by using a cellular phone.
Note
If the PIN code is changed during configuration it will be
checked and this operation lasts about 30 seconds (the cel-
lular phone will be turned off and on again to verify the PIN
code correctness).
Note
If the SIM card PIN number is longer than 4 digits, it has to
be changed before using it in the
HI504903
interface. To
do this, insert the SIM card in a cellular phone and change
the old PIN number with a new one with value from 0000 to
9999, while paying attention to remember the new code (please
refer to the cellular phone instruction manual for the correct
procedure). After that, it is possible to insert the SIM card in
the
HI504903
(see “Installation” section) and use the new
PIN number in the next interface local configuration.
