Intelimax+ Setup

Maxon Intelimax+ serial modem supports a Windows GUI, where by you can configure

the modem via serial connection or remotely via the WAN IP.

Maxon recommends using the GUI connected via a TCP/IP connection in order to

utilise all the configuration settings. When connecting to the Intelimax+ using the GUI

when the modem is in serial modem mode, there will be very limited functionality.

After connecting to the modem using the GUI, users can configure; WAN settings,

Scheduler, IP Stack, SNMP Dynamic DNS and Admin settings.

Intelimax+ User Manual

- 15 -

Connecting to the Intelimax+

TCP/IP Connection - Recommended

Using the TCP/IP connection option allows users to connect to the modem via an IP

connection. Firmware upgrades can ONLY be done when connected via TCP/IP.

Local Connection

To use this feature locally you must follow the following steps:

1. Plug in modem RJ45 power/serial cable then mini USB cable in this order

2. Install USB/LAN drivers which can be downloaded from:

http://www.maxon.com.au/product-supports/drivers-and-manuals.html

3. Set a static IP address to the modem:

Once the drivers are installed you will have to set a static IP on the Intelimax+

network connection (as the Intelimax+ does not support DHCP)

4. The default IP for the Intelimax+ is 192.168.10.1, set your IP within this range

Eg.192.168.10.50

5. Open the GUI to the modem (after modem has booted ~ 1-2 minutes)

The default settings are: Address: 192.168.10.1 (Intelimax+ LAN IP address), Port:

10918, ID: admin, Password: admin. The password has to be reentered when

opening the GUI each time.

Note: If all modem settings are not loaded into the GUI after connection, click the

‘Load from Modem’ button at the bottom to refresh the settings.

Intelimax+ User Manual

- 16 -

Remote Connection

Users can also access the Intelimax+ remotely via a static IP address (e.g. maXwan) or

via a url (e.g. DynDNS)

Serial Port Connection

Use this section to connect to the modem using the provided RJ45 power/serial cable,

the default connection settings are:

Baud Rate: 115200

Data Bits: 8 bit

Parity: None

Stop bit: 1 bit

Flow control: None

Make sure to select the correct COM port and click the open button, the Intelimax+

GUI will connect to the modem via the selected COM port. The GUI can also perform a

search for the correct baud rate if it is not known.

The configuration operations available over a serial connection to the modem are

limited when compared to a TCP/IP connection.

Intelimax+ User Manual

- 17 -

GUI Connection Debugging

1. What if I don’t know the serial interface to the modem?

The modem has a default baud rate of 115200, if you are not able to connect via the

serial interface at any baud rate, then restore the modem to factory defaults by

holding down the reset button for more than 20 seconds (5 second hold is for profile

reset).

2. Why does the Intelimax GUI not connect and reports “The attempt to connect was

forcefully rejected”?

If the Intelimax GUI connection to the modem is not closed with a TCP disconnect the

modem may reject connections and report with a message “The attempt to connect

was forcefully rejected”. This occurs until the modem TCP timeout occurs which will be

either via a modem reboot or after at least 10 minutes. If the connection is local you

can shorten this time by reconnecting the USB interface or under network connections,

selecting the LAN interface to the modem, disabling, then enabling this interface.

3. Why does the Intelimax GUI show that the device is discovered but not connect?

The LAN interface to the modem needs to be configured correctly. This may involve

setting a static IP address to the modem, such as 192.168.10.50 or removing an

incorrect address. The GUI will continue to try to connect to the modem 3 times after

the ‘Open’ button is pressed.

4. Why is the GUI not detecting the Intelimax?

The Intelimax must be powered via the RJ45 connector, then the USB plugged in, after

approximately 1 minute, the PC will prompt for drivers to be installed. The Intelimax

requires the USB/LAN interface drivers installed to be able to talk via a TCP IP

connection to the modem, which can be downloaded from the Maxon website.

There are times where the RNDIS network interface is present under network

connections but not when checked via a command line (ipconfig). If this is the case

then the PC must be restarted as the Microsoft Windows RNDIS driver is not functioning

correctly.

WAN Configuration TAB

WAN configuration page is used to configure how the modem will connect to the 3G

network. Please select the correct operation mode as this will decide if the modem will

automatically connect to the network on power up or work in pass through mode.

The Intelimax supports 6 operation modes:

1. IP Stack Auto mode

2. IP Stack Manual mode

3. Serial mode (Pass-through/Transparent)

4. PPP WAN Auto mode

5. PPP WAN Conditional mode

6. PPP WAN Manual mode

Intelimax+ User Manual

- 21 -

IP Stack Auto Mode

When using IP STACK Auto the modem will behave as an IP Serial modem. When using

this mode the modem will transfer all incoming packets via the serial port to the host

and vice versa. The modem connects to the 3G networks and acquires an IP address

and then runs the IP STACK server or client mode.

Intelimax+ IP Stack can be configured as a Server or Client mode. In Server mode the

Intelimax+ will act as a socket server. The modem will listen on a specific TCP/UDP port

waiting for an incoming client socket connection. As soon as the client drops the socket

connection, the Intelimax+ will go back to socket listening mode as per IP stack

configuration. On the other hand with client mode the Intelimax+ will try to establish a

socket connection to a preconfigured server IP address or DNS name and port number.

The client mode also supports a secondary server IP address just in case the primary

server cannot be reached. The in-built IP stack feature supports smarts such as PPP link

check, TCP link check, PPP link timeout, TCP link timeout and MTU settings.

Secure socket using SSLv3 can be used in both these modes as well as IP Stack Manual

Mode. Further detail on how to configure secure socket is in the IP Stack tab section.

IP Stack Manual Mode

With IPStack manual mode, the modem doesn’t initiate the PPP connection. The

modem will rely on the host on serial port to send the PPP initiation commands and

acquire a WAN IP connection.

The AT command to start the PPP session and open a socket is AT$$IPCTOS.

The AT command to close the socket and PPP session is AT$$IPCTCS.

Further AT command detail is included at the end of this manual.

Serial Modem Mode (Transparent / Pass-through)

This mode allows for the serial interface to connect through to the 3G module in the

modem. In this mode the Intelimax+ processor still has some control and processing

abilities over the serial AT commands and connection processes. Used for PPP pass-

through or Circuit Switched Data (CSD).

Intelimax+ User Manual

- 22 -

Circuit Switch Data Call

Circuit switch is a legacy style of communication where the user dials in to the modem

data terminating number.

Standard set of AT commands used with Circuit Switch Call:

ATD Dial the Data number

ATA Answer the Data Call

ATS0=n Set auto answer where n=number of rings

+++ Escape command to enter AT command mode (1 second gap both

before and after command required to distinguish from data)

ATH Drops the data call

ATO Can return to call if still active

To use this feature please ensure the following has been setup on the SIM:

1. Contact SIM service provider and make sure that CSD is activated on the Sim

card. Generally this requires a second number (data terminating number)

attached to the same service.

2. Configure the modem to auto answer the call or make sure that the equipment

connect to the modem has auto answer activated to detect an incoming call

and sends ATA to answer the data call.

Packet Switch Data Call

The Intelimax+ supports PPP over serial connections through the modem and utilizes

standard AT commands for this purpose. It is recommended that user dial out control

code executes a hang up process command before each reconnection attempt by

issuing a +++ command followed by and ATH command.

Standard set of AT commands used with PPP call:

ATD Dial the PPP number (e.g. *99#)

+++ Escape command to enter AT command mode (1 second gap both

before and after command required to distinguish from data)

ATH Drops the data call

ATO Can return to call if still active

PPP Server Options

The Intelimax+ can be configured to act as a PPP Server over the serial interface with

an independent PPP WAN connection. There are three different PPP modes the

modem can operate in, these are all outlined further in the PPP Server section:

Intelimax+ User Manual

- 23 -

1. PPP WAN Auto mode: Modem is a PPP server over serial with the WAN IP

connection automatically connected.

2. PPP WAN Conditional mode: Modem acts as PPP server with the WAN IP

connection conditional on the serial PPP connection.

3. PPP WAN Manual mode: Modem acts as PPP server and the WAN IP connection

can be controlled via AT over IP commands.

Band Change

When band changing two reboots are required. The first reboot will save the setting to

the module and second reboot will apply the changes to the module so that module

will register to the selected band.

Only bands which are supported by the module will be displayed in this section.

For GSM 900

The user has to tick all GSM 900 bands to be able to connect to the GSM 900 band.

Double reboot is required.

For UMTS 850

The user will be able to lock to UMTS 850 network by just ticking the UMTS 850 band in

the GUI. Double reboot is required.

Scheduler TAB

The scheduler tab allows configuring modem WAN connection schedule. The scheduler

supports two methods of selection. Days of the Week (setup to come on certain days of

the week) or Setting up a certain power up duration (setup to come certain during the

hour).

Scheduler Day of the Week:

Using this option the user can specify days of the week when the modem will connect

to the internet and would be online. The connection and disconnection time is in 24

hour format. While using the scheduler the RS232 and the 3G module can also be

configured to shutdown to save power.

To setup Scheduler by Day of the week, select the Day with connect and disconnect

times. You can also set the modem to power off itself when it disconnects, by checking

the power off check box. To delete an entry click on the entry and press the Remove

selected Item button, or if you want to remove all entered entries click the “Remove

ALL” button.

Scheduler by Duration

Using this method the modem will be powered up for a certain duration, then power

itself down for another period of time, and the cycle repeats itself.

To setup scheduler by duration enter for how long you wish the modem to stay

powered up and enter power cycle duration. The power down will be calculated by

the modem. In the below example the modem will stay powered for 5 min, power

down for 25 min and the cycle is repeated. (Range 0~60 minutes)

Serial port speed setup should be set to match host (connected via serial port)

configuration. With certain applications there may be a need to fabricate a custom

serial cable to work between the host and the Intelimax+. The custom serial cable

depends on the equipment requirements and settings.

Serial Password – Password protected AT commands

The Intelimax+ has the ability to password protect serial interface AT commands. The

serial password can be set on the serial tab. If AT commands need to be entered then

AT commands will return an ERROR message until the interface password is entered first

with the command, AT$$PWD=<password>. Once the password is entered the access

will persist for the session until the modem reboots. Further AT command detail in the AT

Command Password Protection section under the Intelimax+ specific AT Commands

section.

Boot up Message

The Intelimax+ boot up message “INTELIMAX READY” is a message that the modem

sends to the host via serial port upon boot up after a hardware power restart event.

Using this option the user can disable or enable this message.

serial data transferred is encrypted in both client and server modes.

The SSLv3 certificates can be installed using the partial upload function in the GUI using

the following process:

1. Create the certification file for upload to the Intelimax. The certificate files

should be placed into a folder along with a path.txt file.

2. The path .txt file should only contain the text “extra”.

3. Zip this folder, then upload to the Intelimax using the ‘Partial upload’ button in

the GUI, then reboot the modem.

4. Once the modem has rebooted the uploaded certificates can be seen on the

status page under the ‘Extra’ section.

Note: To remove the certificates, upload a .zip file with one file, a path.txt file with the

text “-extra”.

Note: If both SSLv3 IP Stack and secure syslog is used at the same time then the same

private key and certificate are used (the ca.pem certification file is not used by SSLv3).

How to generate SSL certificates:

A SSL certificate can be generated using an application such as OpenSSL

(http://slproweb.com/products/Win32OpenSSL.html, the lite version is fine).

To generate certificate for client and key for client (key.pem, cert.pem):

C:\OpenSSL-Win32\bin>openssl req -new -x509 -days 3650 -nodes -config openssl.cfg -

out cert.pem -keyout key.pem

This application can be run from the command line for example: C:\OpenSSL-
