GPRS iCE3, V1.30 User Guide

2 Overview

2.1 General Characteristics

The iCE3 (iQuest Circuit Extender) has been designed as a cost effective, low power, self-contained circuit
extender to enable communication with equipment over a wireless (GPRS) network connection. Typical
devices that the iCE3 can be used to interface with include dataloggers, PLCs etc.

The unit is based on the Wavecom® M1206/M1306 “Fastrack” GSM/GPRS modem. iQuest have taken the
standard issue modem, modified it internally and developed a comprehensive software application that
resides within the device. This application provides the GPRS network link management, data transfer and
configuration view/edit functionality.

The iCE3 unit comes standard with a d.c power lead and a host device (RS232) cable pre-wired for one of
three different host device types (see Section 7). The SMA antenna 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 lower.

2.2 Typical Applications

The iCE3 can be used in a number of applications, including:

- GPRS circuit extension to third party devices

- GPRS telemetry

- GPRS / RS232 serial gateway to multi-drop networks
The iCE3 provides a very effective means for migration of legacy dialup telemetry networks to more cost-

effective wireless IP communications over GPRS. By simply replacing existing dialup modems with an iCE3,
you can have virtually any logger type telemetered over GPRS. If you are using a HydroTel telemetry
system, the iCE3 can be configured to call-in and be downloaded using a dynamic IP address which further
simplifies the deployment. See Section 2.4.3 for more details.

2.3 Technical Specifications

GPRS iCE3, V1.30 User Guide

2.4 Key Features

2.4.1 Terminal Configuration

All configuration and set-up parameters are modified via a standard ASCII terminal connected to the RS232
serial interface. This means that the user can configure the device without needing to have specialised
configuration software installed on their computer specifically for this purpose.

2.4.2 Wireless Internet Connectivity (GPRS)

Wireless Internet connectivity is provided via the on-board dual-band GPRS modem. Through this interface,
data packets can be transferred to and from the host (RS232) port. To facilitate GPRS 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 iCE3 communicates over a GPRS network using UDP protocol via a single data port. The device
supports ASCII and binary communication to a wide range of iQuest and third party equipment.

2.4.3 Static and Dynamic IP addressing

The iCE3 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 iCE3 to work with any mix of software or device, as each end of the GPRS
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 wider area network.

Dynamic IP addressing requires that HydroTel™ is installed at the remote (base) location. In this mode, the
iCE3 initiates the connection, typically via the Internet and sends a special call-in packet to the base.
HydroTel™ then captures the IP address and port that have been allocated to the iCE3 for that session and
uses them for all ongoing communication with the host device attached to the iCE

3.

Using this mode is

described in detail in Section 5.
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 intelligence of the iCE3 manages the GPRS session establishment and maintenance, meaning that the
host device does not need any special intelligence of its own. However, the host device might be
programmed to force a GPRS connection by issuing a simple command (AT^IGOL), perhaps in responses to
an alarm condition. This feature assumes the device supports the issuing of serial strings on demand.

2.4.4 Gateway Communication

Provision has been made for support for System DO gateway functionality between the GPRS network and
the RS232 serial interface. This enables the unit to be used as a bridge between the wide area GSM
network and a localised network of iQuest devices. By connecting a data radio to the iCE3's serial port, it is
possible to communicate with several devices in a multi-drop radio network from the GPRS network.

The gateway transparently redirects System DO packets received via GPRS from address 0 back out the
serial port if they are not destined for the iCE3. Conversely, packets received on the serial port from any
address and directed to address zero (0) will be transparently redirected onto the GPRS network.

GPRS iCE3, V1.30 User Guide

3 Installation

3.1 Removing / fitting the SIM card

Important! Ensure the iCE3 is depowered before attempting to remove or fit the SIM card.

Using a narrow pointed object, depress the small yellow button to the right of the SIM card carrier. The
carrier will then be ejected. Fit the SIM card into the carrier and gently refit it to the device, pushing it home.

3.2 External Power Supply

The iCE3 does not have an internal battery and so requires an external power supply. It will accept any
external regulated dc power source ranging from 5 to 32Vdc. Although the average current consumption is
very low, it is important that the power supply is capable of delivering the high current peaks that GSM/GPRS
modems are capable of drawing. To this end, iQuest recommend 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.

3.3 Antenna Connection

The iCE3 has a standard SMA antenna connector. For installations with a good GSM signal level, a small
right-angle ground plane independent stubby antenna will provide good results. Such antennae are
available from iQuest or other suppliers. This attaches directly to the SMA connector on the front of the unit.
In areas of marginal coverage, iQuest recommend using an external higher gain antenna.

3.4 Setting the Real Time Clock

If the iCE3 will be used in scheduled connection mode (by using the AT^IACE=2 command), the internal
clock will need to be set correctly after installation on site and all other configuration has been completed.

This step is required because the internal clock is reset to a random time when the iCE3 has been
depowered for any reason. Note that the scheduled connections will still work, they will just not be
synchronised to the correct time of day. Please refer to Section 5 for more details on using the Scheduled
Connection Mode.

Use the clock command in this format: AT^ICLK=”yy/mm/dd,hh:mm:ss”

E.g. AT^ICLK=”07/06/15,08:55:00”
NOTE: The clock can also be read at any time by using the standard AT command AT+CCLK?
The reason for providing a special AT^ICLK command to set the clock is that it automatically synchronises

the scheduler in the iCE3 software rather than just setting the hardware clock as using the AT+CCLK
command does.

3.5 Recommended Deployment Procedure

 Obtain and install the SIM card from your preferred service provider.
 Connect an antenna and power supply to the iCE3
 Using a standard cable (see Section 7.1 for details); connect a computer with a suitable terminal

program such as HyperTerminal®.

 Configure the iCE3 completely before taking it into the field for installation. Use the typical

configuration examples below as a guide.

 If used in conjunction with HydroTel™, configure the station and site in HydroTel for the installation,

including the chosen communication address. This must match the address in the iCE3 if it is to be
used in scheduled (call-in) mode. (AT^IACE=2)

 Test it on-line. If necessary use the AT^IGOL command to force a connection if the auto-connection

mode is not set to continuous (AT^IACE=1)

 Take the iCE3 to site and install it. Take a suitable computer (laptop) and standard cable to allow

testing and further configuration on-site if needed. If required, check the signal strength by either
issuing the command AT+CSQ which is a standard Hayes command to read the received signal
strength indication. (RSSI). For repeated automatic measurements, use the command AT^INFO=1.
See Section 6.3.11 for more details on this command.

 If the iCE3 will be used in scheduled connection mode (by using the AT^IACE=2 command), the final

step is to set the internal clock. Use the standard cable and terminal program on the computer to set
this. See Section 3.4 above for information on using the clock command, AT^ICLK.

 Finally, make sure the correct cable is securely connected to the host device.
 If possible check that the system works end to end.

4 Operation

4.1 LED Indicator

The iCE3 has a single blue LED mounted on the front panel. This indicates the current device status and can
be useful for diagnostic purposes. The various LED indicator states are as follows:

• Single 100ms flash every 2 seconds. Idle (command) mode.

• Two 100ms flashes every 2 seconds. GSM network acquired, connecting.

• Three 100ms flashes every 2 seconds. GPRS connection in final phases.

• One 100ms and one 400ms flash every 2 seconds. On-line in data mode (normal operation).

• Rapid continuous flashing. Waiting for host device wakeup.

(CSI and Unidata loggers only)

4.2 Host Device Type settings and operation

4.2.1 Normal (AT^IHDT=0)

Typical Settings AT^IDFC=0 Forwarding on character disabled.

AT^IDTO=20 Forwarding after 200ms of no more characters from host.

Host Port Communication and Handshaking

On receipt of a GPRS data packet, the iCE3 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 forwarding character not zero) or else no more characters
received for the forwarding timeout period. The packet is then sent to the remote IP address via GPRS.

4.2.2 Campbell Scientific (AT^IHDT=1)

Typical Settings AT^IDFC=0 Forwarding on character disabled.

AT^IDTO=20 Forwarding after 200ms of no further characters from host.

Host Port Communication and Handshaking

On receipt of a GPRS data packet, the iCE3 will assert its CTS line (which is connected to the logger’s RING
line). The iCE3 then waits until the logger responds by raising its ME line. The iCE3 will then output a series of
carriage return characters until the logger detects the baud rate and returns a * prompt. Only then will the
iCE3 send the received data packet to the logger. In reply, characters that are received from the datalogger
are stored until no more characters received for the forwarding timeout period. The packet is then sent back
to the remote IP address via GPRS.

4.2.3 Unidata (AT^IHDT=2)

Typical Settings AT^IDFC=13 Forwarding on character enabled on carriage return (13)

AT^IDTO=0 Forwarding on time disabled.

Host Port Communication and Handshaking

On receipt of a GPRS data packet, the iCE3 will assert its CTS line (which is connected to the logger’s RTS
line). The iCE3 then waits until the logger scans and returns a * prompt. The iCE3 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 packet is then sent back to the remote IP
address via GPRS.

GPRS iCE3, V1.30 User Guide

5 Scheduled Connection Mode

This section describes the use of the scheduled connection mode. This is enabled when the auto-connect
mode is set to 2 by issuing the command AT^IACE=2. Note that whenever a GPRS session is established
by the scheduler, a call-in packet will be sent to the destination IP address (normally a HydroTel™ system).

NOTE: The real time clock must be set by using the AT^ICLK command after installation and if the
unit has been depowered for any reason. See Section 3.4 for details on setting the clock.

NOTE: If a manual connection is required at any time, use the AT^IGOL command to initiate it. The
host device (e.g. datalogger) can be programmed to trigger a call-in by using this command.

The scheduler settings are configured by using the AT^IACS command. Five parameters are needed and
these are as follows:

Start time in day (HHMM) e.g. 600 (6am)
End time in day (HHMM) e.g. 1800 (6pm)
Duration on-line (in seconds) e.g. 120 (2 minutes on-line)
Interval when inside time window (in minutes) e.g. 60 (every hour)
Interval when outside time window (in minutes) e.g. 0 (never)

Start Time

This represents the time at which the iCE3 will start establishing GPRS sessions.

End Time

This represents the time after which the iCE3 will stop establishing GPRS sessions.

Duration

The minimum length of time (in seconds) that the iCE3 will keep each GPRS session active. Note that this
time will be extended if there is ongoing traffic with the device. The session will end when there has been no
activity for the preset duration time.

Interval when inside time window

The length of time in minutes between each successive GPRS sessions being established when the time is
between the start and end times.

Interval when outside time window

The length of time in minutes between each successive GPRS sessions being established when the time is
before the start or after the end time. Set this to zero if no activity should occur outside the normal time
window.

The full command to configure the schedule example below is AT^IACS=600,1800,300,60,0

In this example, the GPRS link is established once per hour (interval = 60 minutes), for a time of 5 minutes
(duration = 300 seconds) starting at 6:00am and ceasing after the 6pm session. Set the start time to 00:00
(0000) and end time to 23:59 (2359) for the on/off cycle to apply regularly throughout the complete day.

6 Terminal Configuration

The iCE3 set up and configuration is achieved through the connection of a terminal to the host (RS232) serial
port. As the iCE3 is very similar to (and in fact based on) a standard GSM/GPRS modem, the design uses
the industry standard Hayes AT command method of configuring and viewing the device’s settings. The
following sections describe how to set up a terminal connection and the menu options that are available
while 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.

NOTE: A suitable cable to connect the iCE3 host (RS232) port to the computer is required. This
should be wired as shown in Section 7.1 (Standard Devices).

6.1 Terminal Set-up

Start Windows® HyperTerminal™ and create a new connection called “iCE3”. Set your terminal properties
as shown in the dialog boxes below.

6.1.1 Port Selection

If you have connected the iCE3 to a communicaton port other than COM1, make the appropriate selection
from the drop-down combo box.

6.1.2 Data Framing Configuration

GPRS iCE3, V1.30 User Guide

The iCE3 RS232 serial port is set by default to a speed of 9600 bps with framing of 8 data bits, no parity and
1 stop bit. Flow control is not required.

GPRS iCE3, V1.30 User Guide

6.1.4 Terminal ASCII Setup

As the iCE3 echoes any received characters once it is in command mode, you will need to disable the “Echo
typed characters locally” mode, otherwise the characters you type in at the terminal doubled up.

6.2 Switching between Data and Command Modes

To view or change the configuration of the iCE3 from the RS232 host port, it is first necessary to switch it to
command mode if the device is in data (on-line transparent) mode. Conversely, the unit can be reconnected
to the network and put back into data mode following a configuration session by issuing an AT^IGOL (Go On
Line) command. (See Section 6.3.7).

To go from data mode to command mode: Type in three + characters in rapid succession. The iCE3 will
respond with an OK followed by a disconnection message.

To go from command mode back to on-line data mode: Type in AT^IGOL, then [Enter]. The unit will go
through its connection sequence and switch to data mode.

NOTE: If auto-connect is not enabled (AT^IACE=0 or 2), the unit will remain in command mode after being
powered up. If the iCE3 has been configured to automatically connect to the GPRS network (AT^IACE=1), it
will connect and go straight to data mode following a power up. If configured for scheduled mode,
(AT^IACE=2), then the connection will be initiated based on the settings entered via the AT^IACS command.

6.3 Special AT Commands

When in command mode, the iCE3 supports the entire standard AT command set accepted by the basic
Wavecom® M1206/M1306 GSM/GPRS modem. To provide a means of viewing and configuring the
customised features of the iCE3, an additional set of special AT commands has been built into the iCE
application software. In order to avoid the common AT prefixes such as AT+ and AT&, all the special
commands begin with ^I, followed by three additional characters which describe the command.

NOTE: Whenever a change to a parameter is made, the new setting is stored in non-volatile memory and
takes effect immediately. This may cause an apparent loss of communication if the host (RS232) port speed
is changed using the AT^IHPS setting. In this case, the terminal program will need to be reconfigured to
resume the session.

The following sub-sections describe the special AT commands and these are listed in alphabetical order.

10 Firmware Upgrade Procedure

IMPORTANT NOTE: There have been different versions of the Wavecom GSM module used during
the production of the iCE

3.

To match the internal operating system in these, iQuest provides multiple
iCE3 firmware variants. The major version number defines the internal module used. Therefore it is
very important that the version be checked (using the AT^IVER command) prior to upgrading the
firmware. For example, if the AT^IVER command returned a version of 2.01, then the latest version
firmware V2.xx would be used.

Firmware upgrades are issued as a single file for downloading and flash upgrading via HyperTerminal®.
The file is available from the iQuest web site and is in the format:

iCE3_GPRS_V120.dwl iCE3 GPRS Firmware, Version 1.30 (Major version 1)

In the upgrade example below, we are upgrading an earlier iCE3 that has version V1.14 installed. The latest
firmware version for this particular model is V1.30.

NOTE: This procedure assumes familiarity with HyperTerminal®, the default serial terminal program that is
supplied with Windows®.

1) Connect to the iCE3 with HyperTerminal. Settings should be 9600bps, no parity, eight data bits and
one stop bit. (9600 n 8 1).

2) Ensure the iCE3 is in command mode by typing AT [Enter]. It should respond with OK. If there is no
response, take the iCE3 off line by typing +++ quickly.

3) Type AT^IVER?[Enter] to display the device version. Check the version to determine if the iCE3
actually requires an update.

OK

4) If so, put the iCE3 into programming mode by entering the command AT+WDWL[Enter]. It will start
transmitting a special prompt character at regular intervals.

5) On the HyperTerminal® menu, select Transfer-> Send File.

iQuest (NZ) Ltd - PO Box 15169, Hamilton, New Zealand Tel: [phone] Fax: [phone] Email: [e-mail] 23

GPRS iCE3, V1.30 User Guide

6) Set the protocol to X-Modem and select the iCE3 firmware file that has been obtained from the
iQuest website. This file is in the format iCE3_GPRS.V115.dwl.

7) Click ‘Send’ and the file should download to the device. IMPORTANT: DO NOT DISCONNECT OR
CANCEL THIS STEP. There is a possibility that interruption of this part of the operation may result
in the inability to reprogram the device. If this occurs, the unit will need to be returned to the factory
to be restored.

8) When download is complete, the iCE3 will resume outputting the prompt character.

9) Type the command AT+CFUN=1[Enter] to reinitialise it.

10) When it has rebooted, recheck the version using the AT^IVER? command once again.
