3 Overview
3.1 General Characteristics
The iCE
3
FX (iQuest Circuit Extender) has been designed as a cost effective, low power, self-contained circuit extender to enable communication with equipment over a wireless (3G) network connection. Typical devices that the iCE
3
FX can be used to interface with include dataloggers, PLCs etc.
The iCE
3
FX unit comes standard with a d.c power lead. A host device (RS232) cable pre-wired for one of
connector allows the use of a small stubby antenna (optional accessory) or alternatively, a coaxial cable to a higher gain external antenna for use in areas where signal strength is low.
3.2 Typical Applications
The iCE
3
FX can be used in a number of applications, including:
Wireless IP telemetry and circuit extension to third party devices
Wireless IP / RS232 serial gateway to multi-drop networks
The iCE
3
FX provides an effective means for the migration of legacy dialup telemetry networks to more costeffective wireless IP communications over 3G. By simply replacing existing dialup modems with an iCE
3
FX, you can have virtually any logger type telemetered over the 3G network. If you are using a HydroTel telemetry system, the iCE
3
FX can be configured to call-in and be downloaded using a dynamic IP address
which further simplifies the deployment. See Section 3.4.4 for more details.

FX User Guide
3.4 Key Features
3.4.1 Terminal Configuration
A small number of diagnostic and initialisation options are available via a standard ASCII terminal connected to the RS232 serial interface. In previous model (iCE
3
3G) nearly all the configuration was also done using the terminal. This has been removed because of the increased features of the FX and data unloading is done using the HyQuest Solutions logger support application, iLink 2012.
Refer to Section 7 for details on the configuration options.
3.4.2 Wireless Internet (IP) Connectivity
Wireless Internet connectivity is provided via the on-board modem. Through this interface, data packets can be transferred to and from the host (RS232) port. To facilitate IP connectivity, a suitably activated SIM card must be installed in the device. It is also necessary to program the unit with appropriate settings via a terminal connected to the host (RS232) serial interface.
The iCE
3
FX communicates over the wireless network using TCP/IP or UDP protocol via a single data port.
The device supports ASCII and binary communication to a wide range of HyQuest Solutions and third party equipment. It also supports consecutive connection to two separate base servers.
3.4.3 Alternative Wireless Connectivity (SMS or FTP)
Another wireless connection mode other than IP is also possible on all hardware variants. This is SMS (Short
Message Service). As with the IP mode described above, using the SMS service requires a SIM card with the SMS service enabled by the service provider.
The SMS option works by sending a pre-set text message to up to ten destination cell phones or SMS receivers. This message contains the site identification and the current values of all enabled sensors. See
Section 8 SMS (Text) Commands for more information on using the SMS feature.
Finally, FTP file transfer is provided for installations requiring a stand-alone data uploads.
3.4.4 Static and Dynamic IP addressing
The iCE
3
FX supports both static (fixed) and dynamic IP address modes. Whether the mode is static or dynamic is set by the service provider and the SIM card supplied by them.
Static IP addressing allows the iCE 3 FX to work with any mix of software or device, as each end of the 3G link knows the IP address of the other end. However, this mode usually requires a dedicated APN or else an additional ongoing cost for a static IP on a wide area network.
Dynamic IP addressing requires that
HydroTel™ is installed at the remote (base) location. In this mode, the iCE
3
FX initiates the connection, typically via the Internet and sends a special call-in packet to the base.
HydroTel
™ then captures the IP address that was allocated to the iCE
3
FX for that session and uses it for all ongoing communication with the host device attached to the iCE 3 FX.
The advantage of dynamic IP addressing is the ability to have low cost IP connectivity to any device supported by HydroTel™. This can be achieved by a simple Internet connection via a local service provider.
The embedded microcontroller in the iCE 3 FX manages the IP session establishment and maintenance, meaning that the host device does not need any special intelligence of its own.
3.4.5 Power Management
The iCE
3
FX supports four distinct power management modes which are listed below. The power save function also has a scheduler which allows the unit to automatically switch from the lowest power state (full power save) to higher level with an active state where it can receive SMS messages and/or remote IP connections.

FX User Guide
No Save
With power management disabled, the internal wireless modem is maintained in a powered on state even when an IP or CSD session is not currently active. While in this state, regular signal strength measurements are made and it is possible to interrogate the internal modem using the AT command set via a terminal connected to the serial interface. The unit is also able to receive and respond to SMS messages when in an idle state.
Partial Save
This mode requires that a three-wire RS232 connection be used (Rx/Tx and Gnd only). If a full
RS232 connection with handshaking lines (specifically DTR) is used, the unit will operate at a similar power level to the
“No Save” mode.
In partial power management mode, the internal wireless modem is maintained in a powered on state even when an IP or CSD session is not currently active just like “No Save”. However, in this mode, no signal strength measurements are made except just prior to a connection being made. This minimises the modem’s power requirements by making use of its automatic UART shutdown function.
It is possible to interrogate the internal modem using the AT command set via a terminal connected to the serial interface. The unit is also able to receive and respond to SMS messages when idle in this mode.
Full Power Save
When power management is set to
“Full Save” power mode, the internal wireless modem remains in a powered off state until the power level is raised by the power scheduler or an IP session is activated via the comms scheduler.
While the modem is in this full-save state, it is not possible to obtain signal strength measurements or interrogate the modem via the AT command set using the Modem Terminal mode. It will also not answer CSD calls, respond to SMS or accept incoming IP connections.
RS232 Only
This mode is provided for applications where the internal modem is not used and telemetry is achieved by a data radio or modem connected to the RS232 port. When in this mode, the RS232 port is used for all callback communication.
3.4.6 Data Logging
The iCE 3 FX supports the logging of data from six virtual sensors, plus a further three internal data sources
(supply voltage, RSSI and internal temperature).
Please refer to Section 10 for a detailed description of the datalogging capabilities of the iCE
3
FX.
3.4.7 Alarm Processing
Each virtual sensor can be checked for up to six separate alarm conditions. Each alarm has separate trigger and reset levels, as well as an activation delay or accumulation period depending upon the data type. If an alarm is triggered it will initiate an IP connection in the same way as the Comms Scheduler or a manual request via the RS232 port (AT^IGOL command) or an SMS message (GOL) initiates a connection.
3.4.8 GPS
As an optional add-on (hardware and software) the modem can be configured to log GPS position (longitude, latitude and altitude) and synchronise the device clock from GPS time.

5 Installation
5.1 Removing / fitting the SIM card
Important! Ensure the iCE
3
FX is depowered before attempting to fit or remove the SIM card.
Also, if the SIM card lock is not engaged (moved fully to the right), the iCE
3
FX will not operate correctly.
Figure 1 - SIM Card Lock
To fit the SIM card, check that the SIM card lock is fully to the left (unlocked). Insert the card with the gold contacts facing upwards and the edge with the chamfered corner facing the unit. Push the card fully into the slot until it clicks into place. Slide the lock fully to the right to engage it.
To remove the SIM card, slide the SIM card lock to the left (unlocked). Then press the SIM card inwards slightly. This will release the latch and allow the card to be extracted from the SIM card carrier.
5.2 External Power Supply
The iCE
3
FX does not have an internal battery and therefore requires an external power supply. It will accept any external dc power source ranging from 5 to 32Vdc. In the later model, this can be logged on a regular
the power supply connection which is part of the I/O connector.
Although the average current consumption is reasonably low, it is important that the power supply is capable of delivering the high current peaks that wireless modems are capable of drawing. To this end, HyQuest
Solutions recommends that a gel-cell type battery be used to power the unit, with appropriate trickle charging from a suitable source. In normal operation, the host device is likely to have a suitable power supply available.
5.3 Power Supply + I/O Connector
On the later hardware revision, the digital and analogue I/O share the power supply connector. The connections are via two flying leads. On earlier hardware units, the two I/O pins are unused. The pin designations of the power supply and I/O connector are shown in the diagram below.

5.5 Antenna Connection
The iCE
3
FX has a standard SMA antenna connector. For installations with a good signal level, a small rightangle ground plane independent stubby antenna will provide good results. Such antennae are available from HyQuest Solutions or other suppliers. This attaches directly to the SMA connector on the front of the unit. In areas of marginal coverage, HyQuest Solutions recommend using an external higher gain antenna.
5.6 Setting the Real Time Clock
If the iCE 3 FX will be used in scheduled connection mode (by using the communication scheduler), the internal clock will need to be checked and if necessary, set correctly after installation on site and all other configuration has been completed. In normal operation, the clock will automatically synchronise to the wireless network time shortly after power up, however a facility to manually set the clock is also provided.
This step is required because the clock is reset to a default time when the iCE
3
FX has been depowered for any reason. The iCE
3
FX makes an attempt to get the best time reference in this case.
If there is no logged data available, the clock will be set to (1 st
January 2012 @ 00:00:00). If logger data is available, the iCE
3
FX will set its clock to a time/date one second past the time stamp of the last record. It does this as it has no idea of how long it has been since the record was logged.
This at least keeps logged data records in chronological order. Note that the schedulers (power and/or comms connections) will still work if the clock has not been synchronised, they will just not
be synchronised to the correct time of day. Please refer to Section 7.3.2 for more details on using
the Scheduled Power Mode.

5.7 Recommended Deployment Procedure
Obtain and install the SIM card from your preferred service provider. Ensure that the SIM card lock
is fully engaged. See Section 5.1 for details on fitting the SIM card.
Connect an antenna and power supply to the iCE
3
FX.
Using a standard cable connect a computer with a suitable terminal program such as iLink or
HyperTerminal®.
Configure the iCE
3 FX completely before taking it into the field for installation. Use the typical configuration at the end of this document as a guide.
If using the datalogging function, configure and check the operation of the real-world inputs if possible.
If used in conjunction with HydroTel™, configure the logger and site in HydroTel™ for the installation, including the chosen communication address. This must match the address in the
iCE
3
FX when used in scheduled (call-in) mode. Note that the iCE
3
FX can be configured to automatically set its address based on its serial number with an optional offset.
Test it on-line. If necessary use the manual connection initiation command ( ”AT^IGOL”) to force a
connection if waiting for the scheduler is not an option. See Section 9.1.
Take the iCE
3
FX to site and install it. Take a suitable computer (laptop) and standard cable to allow testing and further configuration on-site if needed.
As the iCE
3
FX will usually be used in scheduled connection mode, the final step is to check the internal clock. Normally, this will be synchronised to the network time after acquiring the network.
Use the standard cable and terminal program on the computer to check and if necessary, set this.
See Sections 5.6 for information on the clock.
Finally, make sure the correct cable is securely connected to the host device.
If possible check that the system works properly end to end, including communication with the host device.

6.3 Host Device Type settings and operation
The following are the 4 different Host Device Types.
6.3.1 Normal (Type=0)
Typical Settings DFC=0
DTO=20
Forwarding on character disabled.
Forwarding after 200ms of no more characters from host.
Host Port Communication and Handshaking
On receipt of a data packet, the iCE
3
FX will immediately forward it to the host via the RS232 port. The handshaking lines are completely ignored. Conversely, characters that are received from the host are stored until either a matching character is detected (if the forwarding character is not zero) or else no more characters have been received for the forwarding timeout period. The packet is then sent to the remote IP address.
6.3.2 Campbell Scientific Array Based Logger (Type=1)
This mode is used for the older CSI array based loggers such as the CR10/CR10X.
Typical Settings DFC=0
DTO=20
Forwarding on a particular character is disabled.
Forwarding after 200ms if no further characters from host.
Host Port Communication and Handshaking
On receipt of a data packet, the iCE
3 will assert its CTS line (which is connected to the logger’s RING line). If the logger’s ME line is not active, the iCE
3 then waits until the logger responds (by raising its ME line). The iCE 3 FX will then output a series of carriage return characters until the logger detects the selected host port speed and returns a prompt (*).
When the iCE 3 FX determines that the logger is active and at the correct communication speed it will send the received data packet on to the logger. In reply mode, characters that are received from the datalogger are stored until no more characters are received for the forwarding timeout period. The reply packet is then sent back to the remote IP address.
6.3.3 Unidata (Type=2)
Typical Settings DFC=13 Forwarding on character is enabled on carriage return (13)
DTO=0 Forwarding on time is disabled.
Host Port Communication and Handshaking
On receipt of a data packet, the iCE 3 will assert its CTS line (which is connected to the logger’s RTS line).
The iCE
3
FX then waits until the logger scans and returns a * prompt. The iCE
3
FX then sends the received data packet to the logger. In reply, characters that are received from the datalogger are stored until a forwarding character (normally a carriage return) is received. The reply packet is then sent back to the remote IP address.
6.3.4 Standalone (Type=3)
Typical Settings DFC=0
DTO=20
Forwarding on a particular character is disabled.
Forwarding after 200ms if no further characters from host.
Host Port Communication and Handshaking
In this mode, the iCE
3
FX does not link the wireless connection to its RS232 port at all. All data packets are deemed to be for the iCE
3
FX itself and it behaves through the wireless connection just as if it were being communicated to via its RS232 port.

7 Configuration
A small number of diagnostic and initialisation options are available via a standard ASCII terminal connected to the RS232 serial interface. In previous model (iCE
3
3G) nearly all the configuration was also done using the terminal. This has been removed because of the increased features of the FX and data unloading is done using the HyQuest Solutions logger support application, iLink 2012.
The iCE
3
FX will not automatically output the main menu when terminal mode is entered. This is to prevent unwanted data being sent into the attached host device’s RS232 port. To access the terminal, it must be enabled by entering the unlock command AT^ITRM. At any point, the terminal menus can be refreshed by entering the refresh command (“R” or “r”) followed by
Enter. The terminal mode will time out after 2 minutes of inactivity.
The following sections describe how to set up a terminal connection and the menu options that are available whilst connected.
This description assumes a computer running a version of the Microsoft ® Windows ® operating system is being used and the descriptions below relate to the standard Windows
®
terminal emulator application,
HyperTerminal™. Other types of computer and terminal emulators may also be used, but details on the setup required are outside the scope of this document.
A suitable cable to connect the iCE
3
host (RS232) port to the computer is required. This
should be wired as shown in Section 12.1 (Standard Devices).
The iCE3 RS232 port is a DTE (Data Terminal Equipment) configured port and is identical in pin-out and signal alloca tion to that of an IBM compatible PC’s RS232 port. Therefore the cable required is the same as that for computer-to-computer communication and is termed a null-modem cable. These are available from most electronics retailers if required.
To access the iCE 3 FX diagnostic terminal a full null-modem cable between a communication port (e.g.

7.1 Terminal Security Code
The iCE
3
FX supports the use of a text-based security code (of up to 10 characters) that may be used to prevent unauthorised access to the terminal menus.
If used, the code is set using iLink 2012 that is registered to “Administrator” level. If it is empty, the terminal is immediately available as soon as the RS232 connection is made. If the code has been set, then a prompt message is shown and the code must be entered before the terminal becomes available.
The security code is case-sensitive. The code cannot be viewed or changed except by an authorised user using iLink which is registered to Administrator level.
> Enter Security Code (max 10)=
7.2 Terminal Menus
Throughout all the terminal menus, there are two common entry codes.
Menu option 0 (zero) always returns you to the level above your current position.
Entering “r” or “R” when in a menu being prompted for an option will refresh the menu without selecting anything.
When a terminal session has been established with the iCE
3
FX through the RS232 port you will be presented with the main menu. To make a menu selection, type a number followed by <Enter>. Invalid menu selections will result in the display of an error message on the terminal. The current value of each settable item is enclosed in square braces e.g. [1234].

If the internal modem is powered down, the terminal mode is unavailable and this message will appear:
> Wireless module inactive. Terminal unavailable.
Assuming the modem is active, the two scenarios are as follows:
If the internal modem is powered up, but an IP session is not in progress, then it is possible to interact with the modem using the standard AT command set.
If the internal modem is powered up and an IP session is currently in progress, then it is possible to interact with a terminal at the remote end of the connection.
When using transparent terminal mode you must press the <Enter> key after each command or message you wish to send. Press <ESC Enter> to exit the modem terminal session and return to the communication menu.
Option 4

Serial Number as Address
Tick this option if you want the iQuest protocol communication address to be automatically obtained from the device’s serial number.
Base Address
This is the address of the base station to use when calling back using the RS232 telemetry mode. The base address is normally set to zero.
Address Offset
If the “Serial Number as Address” option is enabled, then an additional offset can be entered. Using offsets can be used to categorise units into regions for example.
The serial number plus the offset must still result in an address within the allowable range of 1-
32767.
Gateway Offset
Use 0 to disable gateway communication. If this is not zero, then a gateway block of 100 locations is set up starting from the offset.
Comms Address
When using a manual address, enter a value between 1 and 32767 (the factory default is 1). This address is used to identify the unit in all iQuest protocol communication and must be unique on a HydroTel™ communications interface.
An address of 0 is reserved for the base station (e.g. HydroTel™) and must not be programmed into the iCE
3
. The iCE
3
will always respond to an address of -3 (which is a special
universal address) no matter what its own address is.

Connection Mode
Choose the mode that is used when a connection is initiated by scheduler, manual terminal mode command
(AT^IGOL) or an alarm trigger. The options are IP or SMS.
IP Mode
If the connection mode is set to IP, you have two different options
– TCP or UDP.
TCP Server Up Time
This allows control over the amount of time the iCE 3 will remain active as a listening TCP server after any client connections (primary and optionally, secondary) have been completed. Setting this to 0 will disable the
TCP server mode and in this scenario emulates the older iCE
3
3G software. Otherwise, the unit will remain active and able to accept an incoming TCP client connection from an accepted IP address.
TCP Server Mode Only
If the IP mode is set to TCP, this option enables to keep the iRIS remain in a listening TCP server mode.
Inhibit UDP Announcement
This allows control over whether the iCE
3
will send a call-in (announcement packet) when as scheduled connection is made. In installations where very lengthy connection times are required, where the host device is
“polled”, then a call-in packet on connection is generally not required.
Any UDP connection initiated by an alarm activation, received SMS “GOL” command, RS232
AT^IGOL command or digital input trigger will always send a call-in packet.
UDP ‘Permanent’ Connection
This option is used to enable a permanent UDP connection regardless of the schedule settings.
Dual Base Mode
If this mode is enabled and the secondary IP settings are configured, the iCE
3
will make a connection to both bases in sequence for each connection event (scheduler or manually triggered).
Connect on Startup
If this option is enabled, the device attempts to connect on startup.
Log Modem Comms Diagnostics
If this option is enabled, all the modem communication events are automatically logged along with the RSSI
(signal strength) value that was available at the time of the event occurring.
SIM PIN
When the SIM card used has a PIN code enabled for security purposes, use this option to set it. If a PIN code is not required, enter zero (0) for this setting.
If a SIM PIN is required and an incorrect PIN is entered, the unit will not operate correctly. Also, if a SIM PIN is not required and a PIN is configured, it may lock the SIM card out due to multiple attempts to use an invalid PIN number.
Allow changes to unsafe values
The APN, Username and Password are marked as unsafe values, which may cause loss of comms if set incorrectly remotely. If you want to edit these columns, the option "Allow changes to unsafe values" should be enabled.

Log if delta exceeds
This indicates the amount the latest processed value (in actual engineering units of the sensor) must differ from the last logged value in order to be logged.
Note: The delta logging (if enabled by having a non-zero delta set-point) is done at the time the logging would normally occur for the sensor as configured. All the delta decision does look at the last value that was actually logged and compare it to the newly processed sample value. If the difference is greater than the configured delta value, then the sample is actually logged.
The Normal Log Rate must be equal to or faster than the Routine Log Rate if that is also enabled.

Reset:
Enter a value in engineering units that you want to use as the reset point for the alarm. When the scaled value falls below this limit the alarm will be deactivated. If the reset level is set to a value greater than the trigger level then the alarm is reverse acting. This mode is normally used for low voltage or low water level type alarms.
Duration:
This is the time in seconds to delay alarm activation. This can be used to implement alarm hysteresis for analogue data sources that vary. If the data source is one of the internal counters, then this time is used to totalise individual sample values. If the total over the given alarm duration is above the trigger level then an alarm is generated. Typically this feature is used for rainfall alarms.

If the GPS schedule is configured and valid values have been obtained, these are included in any call-in packet. They are also logged at the rate defined if it is non-zero.
GPS Log Rate (mins)
This is the rate (in minutes) at which the GPS values are logged.
Start Time
Enter the time at which the GPS starts logging the values.
End Time
Enter the time at which the GPS scheduler must stop.
Duration
Enter the duration in seconds that you want to keep each GPS session active.
Interval
This is the length of time in minutes between each successful GPS logging sessions.
Alarm Interval
This is the length of time in minutes between each successive GPS sessions when there are one or more active alarms in the iCE

8 SMS (Text) Commands
The iCE
3
FX is capable of responding to text commands received as SMS messages. This feature allows, for example the unit to be sent a text message to ascertain its status, change a setting or to be put in on-line.
The commands are not case sensitive. If an invalid command is sent to the iCE
3
FX it will reply with an invalid command message.
If the iCE
3
FX is already on-line with an IP session, the processing of the SMS message will be delayed until it disconnects from the IP session.
The three SMS commands supported are:
8.1 Request iCE
3
Information (RQ)
If the message “RQ” is received, the iCE
3 FX will reply to the sender with a message showing basic iCE 3 FX information. The parameters returned are:
iCE
3 date/time,
Site name
Serial number
Last logged value of any “sensor” that is enabled.
Supply Volts
iCE
3 internal temperature
RSSI. Last measured signal strength in dBm.
An example SMS response message to this command is:
12:13:26 > 11 Jun 2010 12:13:26,Site=My Site Name,S/No=AE1-1752, Rainfall=0.0,tot=12.5, Water Lvl= 1.657,Volts= 13.62,Temp=
19.9,RSSI=-71dBm
The sensor value is the last logged value, not the current value. If a particular sensor has not logged (log rate set to zero), then the last logged value returned in the SMS message will be 0.
8.2 Go On-Line (GOL)
If the SMS command
“GOL” is received the iCE
3 FX will immediately initiate a client IP connection sequence as if it was triggered by the scheduler or a manual command through the RS232 port terminal. It will remain on-line for the duration configured in the scheduler.
The iCE
3
FX will not send a reply to this SMS command. This allows an automated connection request to be sent by SMS and the initiation of the client IP connection is deemed to be an acknowledgement of the command.
8.3 Set the Scheduler On Interval (INT)
If the SMS command “INT=x” is received the iCE
3
FX will extract the parameter (x). If this is valid, the value will be used to update the On Interval in the Comms Scheduler.
This gives an external user or service the ability to change the call-in interval (cadence or frequency). The interval parameter must be between 2 and 1440 minutes.
If SMS message forwarding is enabled, the sender’s number and the actual message is sent out the RS232 port in this format. SMS: “Senders Number”,”Message”
E.g. SMS: “+64211234567”,”This is a test message”

9 Host Commands
To allow an intelligent host device to directly perform a small number of actions, there are four special AT commands that the iCE
3
FX will execute immediately without having to invoke the terminal menu.
These commands are only accepted by the iCE
3
FX when it is idle (not on an IP or CSD connection). If it is on-line, any data received on the RS232 port is transparently forwarded to the remote base.
9.1 Go On-Line (AT^IGOL)
If the command “AT^IGOL” is received the iCE
3
FX will immediately initiate an IP connection sequence as if it was triggered by the scheduler or by a “GOL” SMS command. It will remain on-line for the duration configured in the scheduler settings.
9.2 Request iCE
3
Real-Time Clock (AT^ICLK)
If the command AT^ICLK? is received, the iCE
3
FX will respond with its current date and time in a format that will allow simple parsing of the elements by the host.
E.g. for a clock date/time of 16 th
November 2009 at 12:34:56
AT^ICLK?
^ICLK: 2009,11,16,12,34,54
OK
Using this command to synchronise the clock in the host device should be done with care and validity checks. The time may be out by an hour from what is expected depending on the network time sync and the local daylight saving zone status. It is recommended only the minutes and seconds values be used.
9.3 Send manual SMS message (AT^ISMS)
This command allow the ad hoc sending of SMS messages by the host device which can be useful for site initiated alarms direct to personnel. It can be used in conjunction with the SMS message forwarding option where incoming messages are made available to the host device.
When the command “AT^ISMS” is received the iCE
3
FX will then check for and use two parameter strings.
The first string is the destination phone number to send the message to and the second string is the message text. Both strings must be encapsulated in quotes (“).
If the message is sent successfully, the iCE
3
FX will respond with an OK otherwise it will return an ERROR response. E.g.
AT^ISMS=”+6421763953”,”This is a test message from an iCE3”
OK
9.4 Request iCE
3
Received Signal Indication (AT^IRSI)
If the command AT^IRSI? is received, the iCE
3
FX will respond with the current RSSI value (in dBM).
AT^IRSI?
^IRSI: -73
OK

FX User Guide
9.5 Set the Scheduler Call-In Interval (AT^IINT)
This command can be used to check update the On Interval setting in the Comms Scheduler. This gives the host the ability to dynamically change the call-in interval (cadence or frequency) based on certain criteria. If setting the interval, the value parameter must be between 2 and 1440 minutes.
E.g.
Set interval
AT^IINT=180
OK
Read interval AT^IINT?
AT^IINT: 60
OK
9.6 Set a Sensor Source Value for Logging (AT^IVAL)
This command can be used by an intelligent host device to set the value that can be used for a logging source. The command has two parameters. The first is the sensor number to set the value for (1-6). The second is the actual value to set.
E.g. This will set the floating point source value for sensor 1 to 123.45
AT^IVAL=1,123.45
OK
The command will result in an ERROR response if the sensor number is invalid or the input value can’t be decoded.

10 Data Logging
10.1.1 Overview
The iCE 3 FX has an internal data store capable of holding over a million time-stamped samples. This data is stored in a circular buffer in which the oldest records are overwritten when the buffer is full.
To enable this, the iCE
3
FX has six virtual “sensors” that may be configured to use a range of sources.
These sources may be from the real hardware I/O or alternatively from virtual database locations (registers) for future applications that may for example update these via a special program.
Each of the six virtual sensors can obtain information from one of the following seven data sources:
Analogue Input
Pulse Counter attached to the Digital Input
Simulated Pulse Counter enabled by the Digital Input
Frequency Counter attached to the Digital Input
Change of State on the Digital Input.
Internal Integer Database Location (for values obtained via user script or communications link)
Internal F.P Location (for values obtained via AT^IVAL command).
Each sensor can be set up to scale the raw data source into engineering units through the application of a multiplier and offset (slope and constant). The scaled value can be logged to non-volatile memory at rates between once per minute to once per hour or immediately in true event mode for pulse inputs.
It is also possible to configure a sensor to also log derived values such as minimum, maximum, standard deviation (all source types) or a calculated flow rate or volume (pulse type sources only). See the next section for further details on configuring these extended logging features as part of the Sensor Cfg menus.
The data logging time stamps will not be accurate until the iCE
3
FX real-time clock is valid (i.e. has been synchronised manually or from the network). However, all events will be in the correct chronological order as the clock is first initialised to a time one second after the timestamp latest logged sample in the event of a restart.
10.1.2 Logging Internal Parameters
There are three internal parameters that may be logged aside from the four
“free-format” sensors described above. These are supply voltage, RSSI and internal temperature. These may be logged at a rate between 1 and 1440 minutes (24 hours) if required by enabling them in the miscellaneous settings under the Sensor
Configuration menu.
10.1.3 Diagnostic Logging
There is also a “Modem comms diagnostics” logging function. If this function is enabled, several system events are automatically logged along with the RSSI (signal strength) value that was available at the time of the event occurring. The logging of RSSI in this case works in conjunction with any periodic logging of this parameter.
See the next section for the identifiers that are applied to the diagnostic events.

10.1.4 Logged Data Array Identification
The parameters that are able to be logged and their associated array ID codes are as follows:
Sensor sources selected that require hardware support (analogue, digital or supply volts) are only valid in later hardware (serial numbers from AE1-1581). In earlier units the value logged for these will be zero.
The diagnostic logging events are shaded. These only occur if diagnostic logging is enabled.

Table 6 - Logged Data Array ID Definitions
Each virtual sensor’s logged data is identified by an array ID number. For the primary logged data, the ID is the sensor number itself. For the optional supplementary data (min, max, deviation, flow/vol), the array ID has an offset added to the sensor number that it is derived from. These ID offsets are as follows:
Minimum:
Maximum:
Diagnostic logging
Flow/Vol
+20
+40
(60-69)
+80
For example, Sensor 4 has been configured to log the average value, plus the maximumThree data arrays will be logged for this sensor at each logging interval with IDs of 4, 44 respectively.
Array 0 (zero) is a special array identifier and is used a system event log. Currently this is
only used to log a restart (either at the initial connection of power, on a watchdog reset or a user program start after an upgrade). The logged value in this case is always zero. In
HydroTel the identifier for this item is 0.

11 Troubleshooting
This section offers some possible answers to common installation and/or configuration issues.
11.1 iCE
3
will not respond in RS232 terminal (configuration) mode
Prompt: When the iCE
3 is in terminal mode through the either the RS232 port or via a CSD link, the current menu can be refreshed by using “R” or “r” command. Try entering an R, then Enter to attempt to refresh the menu.
Port Speed:
In the case of RS232, the computer port speed setting must match the speed configured in the iCE 3 . If you are unsure of the port speed, de-power and re-power the iCE 3 and check the
status LED for port speed indication. See Section 6.1.1.
Connection: If the iCE
3
is connected on an IP session, the RS232 terminal mode is unavailable. To disconnect from the IP session and return the unit to idle, thereby activating terminal mode, use the standard modem AT escape sequence (+++).
11.2 Unable to connect to the remote TCP or UDP server
SIM Card:
SIM PIN:
Check the SIM card is active and the account is in credit (if prepay).
Check the PIN code for the SIM card is correctly configured in the Modem section in Comms
APN: configuration menu.
The unit must be configured for a valid APN that must also match the SIM account APN.
The iCE
3
will not attempt to connect if the RSSI is 0 or less than -113dBm. Use a higher gain Signal: antenna if the signal strength is marginal.
IP Settings: The iCE 3 will not attempt to connect unless the primary IP and port are defined. I.e. the IP address is valid and the port is non-zero.
TCP Server:
The remote server is not available. Check that the TCP server is operational and configured correctly and also that the necessary firewall access is enabled for the TCP port and the complete dynamic IP address range that the iCE 3 could be allocated by the network.
11.3 iCE
3
will not respond to SMS requests
SIM Card:
SIM PIN:
Check the SIM card is active and the account is in credit (if prepay).
Check the PIN code for the SIM card is correctly configured in the Modem section in the
Comms configuration menu.
Power Mode: If Full Power Save is selected, the wireless modem is disabled and will not respond.
Connection: If the iCE
3 is connected on an IP (3G) session, the SMS feature is unavailable at that time; however the message will be replied to when unit returns to idle. Configure the scheduled IP
Signal: connection to minimise the time that SMS is unavailable.
The iCE
3
may not respond if the signal strength (RSSI) is very low. Use a higher gain antenna if the signal strength is marginal.

13 Firmware/Software Upgrade Procedure
13.1 Overview
This section describes the procedure to use when upgrading the firmware/software components in an iCE
3
.
The upgrade procedure has been carried out many times without issue. However, because the process does involve erasing and reprogramming of flash memory, it is important that a good, securely connected power supply is provided to the iCE
3
throughout the upgrade process.
13.2 File Naming Conventions
13.2.1 iCE

Frequently asked questions
The iCE3 FX is a wireless circuit extender that enables communication with remote equipment over a 3G network. It acts as a bridge between your local devices (like dataloggers) and a remote server, allowing you to monitor and control data from a distance.
The iCE3 FX offers several communication options: wireless Internet (IP) for data transfer over the internet, SMS (Short Message Service) for text-based updates, and FTP file transfer for uploading data to a remote server. You can choose the mode that best suits your needs.
The iCE3 FX offers four power management modes to optimize energy consumption. The 'No Save' mode keeps the modem constantly active, while 'Partial Save' and 'Full Power Save' modes conserve power when the device is idle. The 'RS232 Only' mode is for applications where the internal modem is not used.
