How it works

Overview:

GSMX-4400 is supplied with Windows© based software called “EzGSM”. The software enables up to 10

mobile phone numbers to be defined, a description for the site, a description for each Digital input and

Output as well as the Polarity of Digital Input alarms.

The system requires a user-supplied SIM card. The SIM card is available from mobile phone vendors. It is

recommended the SIM is not “Pre-Paid” as the GSMX™ system has no way of determining when the card’s

credit expires. The SIM card should also have the PIN number removed before using with GSMX-4400. This

can be done by the provider or by placing the SIM card into a mobile phone and disabling the SIM PIN feature

using the phone’s setup function.

The standard GSMX-4400 system requires 12V or 24V DC to operate. The system can be provided with

optional Mains Plug-Pack, 230VAC supply(as shown in picture on front page) or Solar power supply.

Types of Input:

The GSMX-4400 system can accept a variety of digital inputs and control a variety of ON/OFF outputs.

Typical Inputs and Outputs:

Switches

Relay contacts

PLC inputs and outputs

Push buttons

Solenoid valves

Relays

Digital temperature probe, Cable length limited to 5m from enclosure



Alert Messages

GSMX-4400 can send several types of text message to the mobile phone numbers setup using the EzGSM

software.

When the system is powered up, a “Power Up” system message will be sent to notify that the system has

been switched on.

If the 230VAC mains supply or Mains plug-pack option is fitted, the system will send a “Mains Loss” alert if the

mains power supply is lost at any time. A “Mains Restore” message will be sent when power is restored after

a mains loss occurs.

The system also monitors the Battery voltage (if solar power supply or battery backup is fitted). In event the

battery voltage drops below 10.5V a “Low Battery” alert message will be sent. Once the battery level is re-

stored (rises above 11.5V) a “Battery Restore” message will be sent.

Sending commands to GSMX-4400 from mobile phone

The current Digital input and output states and Battery voltage can be obtained at any time using any mobile

phone. The user sends a user defined password followed by the word “status” to the GSMX-4400 unit. The

unit will then send back the current Input and outputs status as well as Battery voltage to the mobile phone

that sent the request.

The digital outputs can be controlled by mobile phone by sending a command to switch either output ON or

OFF. This is typically useful for activating a cooling fan or other device in event of over or under temperature

situation.

The GSMX-4400-OD unit can be supplied pre-fitted with a 230VAC/10A rated relay contact for each output.

This option needs to be requested at time of ordering the system.



Installation

Locating the unit:

The GSMX4400 Unit should be located close to the points being monitored. If the Orbit Digital temperature

sensor is being used, the probe must be located with the 5m maximum length of the cable.

Power Supply:

GSMX-4400 requires an operating voltage of 12V or 24V DC with current capacity up to 1.5Amps peak. The

system can be powered by 230 VAC/12V Plug-pack, 230VAC fixed-wired supply or backup battery that is

connected to a charging unit or Solar panel rated at 10W or higher. These options are available from Orbit

Communications Pty Ltd.

Antenna:

The GSMX-4400 is supplied with a GSM Antenna fitted directly to the top of the enclosure. The unit should be

located in a position where there is suitable GSM signal strength to operate reliably on the GSM or Next-G mo-

bile phone networks. This location can easily be determined using the signal strength indicator on a mobile

phone. Metal objects should not be located closely to the GSM antenna.



GSM Dialler

GSMX-4400-OD contains a GSM/Next-G dialler unit that will operate on worldwide GSM and Next-G/3G mobile

phone networks. All that is needed to use the GSMX unit is an active SIM card. These cards are normally pro-

vided through mobile phone vendors.

Note: It is recommended NOT to use a pre-paid SIM card as the system has know means to identify when the

card requires topping up.

Some SIM cards supplied have PIN Numbers (It is recommended the PIN is removed before attempting to use the SIM with the GSMX

device).

This process can be done by the SIM card provider at time of purchase of the SIM or the PIN can be removed by placing into a mobile

phone and disable the PIN number. (Refer to your mobile phone user guide for details of how to disable the PIN function on the SIM

card).



Setting up GSMX-4400

The GSMX-4400 system can be configured using Windows® software called “EzGSM”. This software is used to

set up the system. The preferred method of installation is from Orbit’s Updates web site. The install program

can be located at http://orbitcoms.com/updates/ezgsmdn/setupEzGSM.htm . Click “Install” from the web site to install

the program directly from the web site. Once installed, the EzGSM software will check for updates every time

the program is run to ensure it is the latest version.

Using EzGSM setup software

EzGSM must first be installed onto a desktop or laptop computer. The software is used to program the settings

into the GSMX-4400 unit. Once GSMX-4400 has been set up, the cable can be removed and the system will op-

erate as programmed. The settings will remain in the GSMX-4400 unit even after power down and can only be

modified using EzGSM software.

Serial Port GSMX-4400 connects to the computer using an RS485 serial link. A DB9 connector is wired directly to the GSMX-4400 unit inside the enclosure. A RS485 to USB adaptor device is provided to enable the unit to attach to a computer for setting up. A disk with drivers for various operating systems is provided with the system.

To insert SIM Card:

The SIM card is inserted into a socket behind the front panel. To install the SIM the plastic front panel must be removed.

This is done my carefully wedging a small screwdriver in the slot at the top of the plastic front panel.

Be careful to only lift the plastic cover

until it comes clear of the top as shown.

Do NOT stretch the thin cable that

connects GSM antenna to front



SIM is inserted into slot with Contacts DOWN and notch at front left as shown.

The SIM will click into place when pushed into the socket. To remove the SIM simply push the SIM until it clicks

and it will pop out enough to remove by finger.



Running the software:

Install EzGSM onto the computer from the web site as previously described. Once EzGSM software is installed,

an icon will be placed on the desktop of the computer. Run the software using the desktop icon.

Note: The first time EzGSM is run, the serial port used to connect to the device must be selected. All available

serial ports will be listed in the “Serial Port” pull down menu. Simply click the appropriate port to select.

Once the appropriate port has been selected the program can be used to set up the GSMX-4400 unit. Ensure the Device is powered and connected to the serial port of the computer using the supplied RS485 to USB adaptor. Click “Connect” to establish connection with GSMX-4400. The Menu Tabs should now be displayed and the bottom status line will indicate the type of GSMX device connected.

Any time changes are made, the “SAVE” button must be clicked on bottom right of screen to save changes to the GSMX-4400. The main screen enables a description to be entered for the site, an access password (this password is used when contacting GSMX-4400 by mobile phone to prevent unauthorised access. The Mains Loss Detect can be change by clicking to switch the function ON or OFF. This function is only used when a 12V DC battery backup system option is fitted. It will ensure mains failures are detected and mains loss notification to be sent.



The GSMX is provided with NO phone numbers set up. Before the system can send SMS alerts, at least one

phone number must be entered (Note: The system will still receive SMS commands from mobile phones even

when no phone numbers are set as it will return the result to the calling phone).

Select “Phone Book” tab to set up phone numbers.

Click “ADD” button to add a new mobile phone number to the list. Up to 10 Mobile phone numbers can be

used. Edit the “Contact Name” box to enter a description of the phone number and then the phone number in

the “Mobile Phone Number” box. The number can be entered in local format “0459563898” or international

format “+61459563898”. (Do not add “ marks).

Numbers can be removed by selecting a number in the list and click “Remove”.

Numbers can be edited by selecting number in list and selecting “Edit”

Click “SAVE” to save the phone numbers to GSMX-4400 when done.



To set up the Outputs. Select the “Relay outputs” tab.

The various text details are sent with each SMS alert message and when requesting status information and

other SMS commands.

The description of each output can be entered in “Title” box. [8 Characters max]

“ON Text” is the text shown when the Relay is activated (ON). [7 Characters max]

“OFF Text” is text shown when the Relay is deactivated (OFF). [7 Characters max]

The relay can be manually switched ON and OFF by licking the “Set State” switch. Ie. The actual relay on the

GSMX-4400 unit will switch ON and OFF in real time when these buttons are pressed.

“Current State” Displays the actual real time current state of the Relay.

Example:

Relay 1 may be used to control a Generator. The Title might be set as say “Genset”, the ON text as “Running”

and Off text as “Stopped”.

If Relay 1 was activated and a status request was sent to the unit then the text shown for that relay would be…

“GenSet Running”

Click “Save” when done to save changes to GSMX-4400.



To set up the Inputs. Select the “Digital Inputs” tab.

The various text details are sent with each SMS alert message and when requesting status information and

other SMS commands.

The description of each output can be entered in “Title” box. [8 Characters max]

“ON Text” is the text shown when the Input is activated (ON). [7 Characters max]

“OFF Text” is text shown when the Input is deactivated (OFF). [7 Characters max]

The Activated state is controlled by “Alarm State”. If Alarm State is “CLOSED” then an alarm will be sent with

“ON Text” when input is grounded (pulled low). If “Alarm State” is “OPEN” then the “ON Text” will be sent

when input is OPEN or floating. The “Off Text” is sent in the opposite state to Trip State.

The “Trip Delay” enables an input alarm to be ignored for a certain number of minutes before activating the

SMS alert. The range is 0 to 240 minutes (where 0 = instant).

Current State is read from the device in Real time when the “Digital Inputs” tab is selected. It is read again any

time the “Read” button is clicked.

“TEST SMS” causes a Status message to be sent immediately to all mobile phones in the Phone Book list.

“INIT SMS” reinitializes the GSMX-4400 SMS unit. This can take up to 30 seconds and results in Power Up mes-

sage being sent to all numbers in Phone Book when system has reinitialized.

“SIM” reports if SIM card is OK

“NETWORK” reports if SMS is successfully registered on a mobile phone network.

Start Up Sequence

The POWER LED should initially come on and then blink at a rate of around 1 second for approximately 12 seconds.

After this time the POWER LED should be ON solid.

The LINK LED should come on after a short time. This indicates the SMS module is working correctly.

Next, the SEND LED will be switched ON. This indicates the SIM card is ready and ok to use.

Finally the RECEIVE LED should be switched ON to indicate the system has registered ok with mobile phone network.

A short time later, the 4 bottom row LEDs should light in sequence and then go OFF.

Now a Power up message will be sent.

When ever a message is being sent the SEND LED will come on for around 5-6 seconds. If the message is successfully transferred to

the mobile phone network then the SEND LED will blink 3 times and switch OFF.

A Power up message should be received on all mobile phones entered in the Phone Book.

Receiving a SMS:

The RECEIVE LED should light briefly and then switch OFF.

Then the normal Send sequence described above should occur as the GSMX-4400 proceeds to send the response to the mobile that

send the SMS to the unit. Note: Only the mobile which sent the request will receive a response, whereas ALL phones in the Phone

book will receive Alert messages generated by the GSMX-4400.



Main Loss Detection

A check box in the General settings area of the EzGSM screen contains a checkbox labelled

“Mains Loss Detect”.

This is to be selected when a battery back-up system option has been installed. When selected, the GSMX unit

will send a Mains Loss SMS alert when the mains power that is charging the battery is lost. The detection may

take up to 5 minutes.

If the mains is restored then a Mains Restore message will be sent. The mains loss occurs when the input sup-

ply voltage falls below 12.9V DC. (Note: If the charger is not being used this feature should not be enabled as

an alarm will be sent when power supply voltage is below 12.9V DC). The Mains Restore level occurs at

13.3V DC.

Battery Low Detection

If the battery voltage falls below 10.7V DC, a Low Battery SMS message alert will be sent. A Battery Restore

message will be sent when voltage rises above 11.5V DC.

The current Battery/Supply voltage can be determined by selecting “Read Device” option in EzGSM software or

by requesting “status” using mobile phone.



Text Message commands The format for commands sent to the GSMX device...

[Password] [Single Space] [Command] The password is selected using EzGSM software provided. Note: The text is NOT case sensitive but there must be only a SINGLE SPACE between password and command. Example: Send a command to switch ON R1 Output. As-sume the password was set to gsm Create a text message on the mobile phone using the phone number set us-ing the supplied configuration software and then enter the following text as the message and Send... “gsm R1ON”

Digital Inputs

The Digital Inputs are pulled up to +3.3V DC via an internal pull-up resistor. The

inputs can tolerate over voltage and reverse polarity voltage to +/- 30V DC.

Voltages applied outside of this range may cause damage.

The Digital inputs can be operated using any voltage free contact (such as a Relay

contact, open drain or open collector output from another device or a switch), the

input can also be connected to a voltage source (recommend 0V to 10V

maximum). Note: The Common side of the input devices must connect to the

GROUND terminal of the RTU device.

Relay Outputs

The RTU Relay outputs are rated at maximum load of 230VAC and 2 Amps.

Additional voltage or current capacity can be obtained by addition of external

relays. Orbit can provide external relays and latching relays.
