MODE M S E T U P
Intelimax+ serial modem supports a Windows GUI software, where by you can configure
the modem via serial/USB 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+4G User Manual

Connecting to the Intelimax+4G
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. Connect the GUI to the modem after modem has booted (1-2 minutes after
powered)
The default settings are: Address: 192.168.10.1 (Intelimax+ LAN IP address), Port:
10918, ID: admin, Password: admin. The password has to be re-entered 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.
Remote Connection
Users can also access the Intelimax+ remotely via a static IP address (e.g. maXwan) or
via a url (e.g. DynDNS):
Intelimax+4G User Manual

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
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+4G User Manual

GUI Connection Troubleshooting
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/4G 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+4G User Manual
- 20 -
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/4G 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 cellular 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 Packet
Switched Date (PPP Pass-through) or Circuit Switched Data (CSD).
Circuit Switch Data Call
Circuit switch is a legacy style of communication where the user dials in to the modem
data terminating number. Circuit Switched Data call only operates under 3G network.
Standard set of AT commands used with Circuit Switch Call:
ATD Dial the Data number
Intelimax+4G User Manual
- 21 -
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 Switched 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
When using a PPP dial up connection from the modem, the following commands have
to be issued before starting the connection:
AT+CGDCONT=1,"IP","apn" Set the access point name (APN).
AT^SGAUTH=1,auth_type,"userid","password”
Set the Authentication. auth_type can be: 0 - NONE, 1 - PAP, 2 – CHAP.
PPP Server Options
The Intelimax+ can be configured to act as a local PPP Server over the serial interface
with an independent WAN connection. There are three different PPP modes the modem
can operate in, which are all outlined further in the PPP Server section:
1. PPP WAN Auto mode: Modem is a PPP server over serial with the WAN IP
connection automatically connected.
Intelimax+4G User Manual
- 22 -
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.
WAN Connection Retries
The modem will reboot itself if it fails to get WAN IP after a pre-defined numbers of retries.
This can be configured in Retry times field. The default times is 10 and can be set from 2
to 100. The retry times can also be set via AT command us AT$$RETRYTO.
Band Change
When band changing two reboots may be 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.

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-
Win32\bin>openssl req -new -x509 -days 365 -nodes -config openssl.cfg -out cert.pem -
keyout key.pem.
The resultant 2 certificate files contained in the /bin folder and are named: cert.pem and
key.pem.
IP Stack Modes
Intelimax+ supports operation of the IP Stack in either client or server modes:
