tion, please refer to “Appendix, section 3” for details about
making a longer communication cable.
HI504903 is provided with a digital input, which can be
configured with HI504903SW software (see “Interface Configuration” section) to send an alarm SMS when a DC voltage
from 5 to 30 V is applied or when it is disconnected.
This input can come from a relay contact or from an open
collector output (for example from a PLC).
Connect the positive pole of an external power supply to the
positive DIG-IN terminal; connect a command relay between
the negative pole of the external power supply and the negative DIG-IN (see also below diagram).
DIG-IN terminal.
DISABLE SMS (DISABLE)
This input works as a digital input (see previous subsection)
and allows to ignore active errors and suspend SMS sending
during operations as start-up, maintenance, etc.
DIGITAL OUTPUT (DIG OUT)
This optoisolated terminal is an open collector output, which
can be used for external signaling through LED indicators or
small relays (see below diagram).
RS485 SERIAL PORT
HI504903 is also provided with a 2-pin RS485 terminal for
communication with Hanna HI142 temperature dataloggers.
The RS485 standard is a digital transmission method that
allows long line connections. Its current loop system makes
this standard suitable for data transmission in noisy environments.
Specifications:
The RS485 standard is implemented in HI504903 interface
with the following characteristic:
Data rate: fixed to 1200 bps for communication with
HI142 temperature dataloggers
Communication: bidirectional Half-Duplex
Line length: up to 1.2 Km typical, with 24 AWG cable
Loads: up to 32 typical
Internal termination: none
Connections:
The RS485 port of HI504903 can connect up to 31 HI142
dataloggers on the same physical network, with a total line
length up to 1.2 Km using a 24 AWG cable.
For connecting the first HI142 to the supervisor, use a cable made as shown in the
“Appendix, section 1” and connect the A and
B wires to the A and B pins of the HI504903
RS485 terminal.
1312
To connect the subsequent dataloggers one to the other, use
a cable with RJ11 plugs, made as explained in the “Appendix, section 2”.
To terminate the line, plug on the last HI142 the termination
key supplied with the HI504903 supervisor.
All the instruments connected to the RS485 port are “slave”
devices that are queried by the HI504903 supervisor. In
other words, the interface can work only as a “master” component, whereas the connected instruments work as remote
terminal equipments answering to the commands only.
Each HI142 instrument is identified by an unique address
number, included in the 000001 to 999999 interval, which
corresponds to the Serial Number of the temperature
datalogger.
As additional feature, the HI504903 interface is also provided with internal Fail Safe Open Line protection method.
To minimize electromagnetic interferences, it is recommended
to use shielded and twisted pair cable to connect the units.
POWER SUPPLY INPUT
The power supply input terminal can be used for powering
both the HI504903 supervisor (directly from the mains with
a 12VDC adapter) and the HI142 network (through the supervisor).
For HI504903, use a 12VDC adapter
(HI710005 or HI710006) and connect
the black wire to the positive input terminal
(marked “+”) and the black & white wire to
the negative one (marked “-”).
For HI142 network, connect the first HI142
using a cable made as shown in the “Appendix, section 1” and connect the “+” and
“-” wires to the “+” and “-” pins of the
HI504903 power supply connector.
All hard wiring can be accomplished through four cable
glands on the bottom side of the case, by passing
wires through the rubber grommets and tightening
the nuts.
Note All connected cables should end with cable lugs.
BATTERY
FOR SAVING BATTERY, THE HI504903 IS SUPPLIED WITH BATTERY NOT CONNECTED.
PLUG THE BATTERY CONNECTOR BEFORE
STARTING OPERATION.
Use only rechargeable sealed lead-acid battery with
12 V and 0.8 Ah capability.

SIM CARD INSERTION
To substitute battery, please follow below instructions:
1. turn off the HI504903: turn OFF the power switch and
disconnect the interface from the mains;
2. remove the screws on the bottom of the two battery clips;
3. disconnect the battery cable from its connector;
4. substitute the old battery with a new one;
5. fix back the two girdles by tightening the screws;
6. connect the battery cable to the connector;
7. connect the interface to the mains;
8. turn ON the power switch.
the battery connector, otherwise an alarm SMS will be sent
immediately after the start-up procedure (see “Fault Condition” section for details).
tution, it is possible that an alarm SMS of “Battery failure” is
sent. Ignore that message and check if the error is still active the
day after. For avoiding this problem, connect the unit to the
mains and wait for at least 10 hours before turning ON the
power switch. In this manner the new battery can be charged.
Before using the HI504903, insert a SIM card.
• Press the SIM card holder ejector on the cellular module
by using a sharp item (for example, a pen);
• Insert the SIM card in the holder and push it back in the
housing.
Note If the HI504903 has to be used for sending alarm
SMS, be sure that the SIM card can support voice
calls. If the HI504903 will be used for remote connection session, be sure that the SIM card supports
data calls. Please contact the cellular network operator for information about SIM active services.
Note Do not remove the SIM card while voltage is applied
to cellular phone. Before removing the card, turn off
the interface. Failure to do so may seriously affect
the serviceability of the HI504903.
START-UP
Turn ON the power switch (#14
on page 8): the red SMS disable
LED lights up and will stay in this
state until the start-up procedure
ended and the idle mode is entered.
During start-up procedure the Real Time Clock (RTC) is
checked to control if a reset occurred since last software initialization. In this case, the RTC is initialized with the default
date and time 01/01/2000 - 00:00. An EEPROM reset does
not affect the RTC settings.
The EEPROM is also checked to control if it is new. In this
case, the default values are copied from ROM and the device enters normal mode. Otherwise an EEPROM checksum
test is performed (the same is performed periodically during
EEPROM selftest procedure, see “Fault Condition and Selftest
Procedure” section for more details).
If checksum is not correct, the proper EEPROM error LED
indication will be given as soon as the Idle state is entered.
During start-up, the internal cellular phone is turned ON
and an initialization procedure is performed to insert PIN
code and make network registration for enabling incoming
and outcoming calls. Moreover, the telephone answering
service is disabled to avoid automatic network call forwarding if interface is busy and can not serve immediately incoming
call.
Initialization procedure can last up to 30 seconds if no problem occurs, otherwise some more time could be needed and
proper cellular LED indication will be given in idle state.
When the start-up procedure is complete, the interface enters
the idle state.
Note When the HI504903 is turned ON for the first time, it is
possible to get a cellular error indication. This can happen if
the SIM card requests a PIN code to be registered in the
network and the interface was not yet configured (see “Local
configuration” section for details).
1716
IDLE STATE
The idle state is the normal operation state for the HI504903
supervisor. While in idle state, the following main tasks are
fulfilled:
• Management of incoming remote connection and configuration requests (see “Interface configuration” and “PC
communication” sections for details);
• Management of incoming local connection and configuration requests;
• Polling procedure of connected devices;
• Diagnostic selftest procedures: battery test, cellular phone
test, EEPROM corruption data test (see “Fault condition”
and “SMS delivery” sections);
• Processing of incoming SMS’s for digital output control (if
enabled) and information SMS’s request (see “SMS delivery” section);
• Sending of alarm SMS’s or information SMS’s upon user
request (see “SMS delivery” section).
When in idle state, the HI504903 can perform periodically
some diagnostic selftest procedures as: internal backup battery test, cellular phone test, EEPROM corruption data test. If
one of these tests does not pass, the interface advises the
user with a visual indication about the problem using the red
and green SMS enable/disable LED’s. Please refer to “Fault
conditions and Selftest Procedures” section for more complete indications about interface related fault conditions.
Moreover, every 30 seconds the two green LED’s for cellular
phone signal are updated with the current signal strength,
and the indication meanings are listed in the table below:
LED Status Meaning
Cell Signal 1 (green) OFF No signal or
Cell Signal 2 (green) OFF cellular error found
Cell Signal 1 (green) ON Medium signal
Cell Signal 2 (green) OFF
Cell Signal 1 (green) ON Strong signal
Cell Signal 2 (green) ON
Also the digital output status LED is updated with the current
status of the digital output contact. The digital output contact
status can be changed by the user only by sending the proper
SMS to the interface. The below table shows the digital output
LED indication depending on the digital output status:
LED Status Meaning
Digital Output OF F Dig.output contact open
(yellow) ON Dig.output contact closed
Note The status of the digital output contact is saved in HI504903
internal memory, so that the digital output is set to the correct
value in case of a reset or after a start-up of the interface.
During polling procedure all devices connected to the interface through RS485 serial ports and digital input port (if
correctly configured, see “Interface Configuration” section)
are periodically queried to acquire their current status, measurement values and active alarms. The delay between a query
operation and the following one is user selectable, and can
vary from 1 to 10 minutes (see “Query Delay” field and “Interface Configuration” section).
If many devices are connected to the RS485 link and the
cellular phone interface can not interrogate all the devices
within the selected delay time, then the actual interval becomes longer than the set value.
When polling devices procedure is completed, the RS485
serial port LED (#1 on page 9) lights up if an alarm is active
at least in one of the instruments connected to the RS485 port
(up to 31 devices can be connected on the same RS485
port); the digital input port LED turns on or off depending on
the user-selected logic for closed contact (if control of digital
input port was user-enabled during last interface configuration).
Moreover, if an active alarm found in a device connected to
the HI504903 matches with one of those selected by the
user during last interface configuration, or if the digital input
status matches with the condition selected for triggering an
alarm message, then one (or more) SMS(s) are immediately
submitted by the HI504903 to the set cellular phone
number(s) (see “SMS delivery” section).
Note The “Query Delay” time value fixes the maximum delay be-
tween an alarm occurrence in a device and the related alarm
