RFI will be releasing our new 4G CAT1 version of Maxon’s Intelimax Lite serial modem in April. This will be the first LTE CAT1 modem (with 700 MHz band 28 support) in Australia with a cellular engine that will have approvals from all major carriers in the country.
The Intelimax Lite 4G is designed specifically as a cost-effective serial modem where standard features of data communications are required. This device is ideally suited for low power and low data rate applications in 4G. It is designed to meet the requirements of the cutting-edge LTE market.
The Intelimax Lite 4G has all the essential functionality for today’s M2M environment including Packet Switch Data, 2-way SMS, Circuit Switch Data and IP Stack. This compact and economical device is the ideal solution for high volume applications. The device is easy to configure via AT Commands or Windows GUI and its plug-and-play capability makes the Intelimax Lite 4G the perfect choice for your entry level M2M telemetry requirements.
The Intelimax Family
The Intelimax family of cellular modems already has an excellent reputation as a reliable industrial modem in the 3G range. This Maxon range includes Intelimax, Intelimax+ and Intelimax Lite - widely used in different industries in applications such as remote meter reading, SCADA telemetry, tracking and fleet management.
Intelimax+ and Intelimax Lite have arrived...... Packed with features - The Intelimax has been refreshed to offer you new enhancements to improve the security, reliability and performance of your industrial M2M communications.
The Intelimax+ is a 3G serial modem designed in Australia for industrial M2M remote monitoring applications as well as data collection and controlling the flow of data between devices and control equipment.
The Intelimax+ is engineered especially to withstand Australia’s vast climate and extreme environmental conditions with operating temperatures between -30° to 85°c. The Intelimax+ has an impressive full feature set including extensive event recording, connection management, fault recovery, security features, and remote firmware upgradability. Carried over from it’s predecessor, it also boasts enhanced capabilities such as CSD to IP, remote AT commands, SSH, Telnet, remote management, onboard IP stack, FTP and a variety of security features including; secure AT commands, SSLv3 socket, SNMPv3 and secure syslog content.
The Intelimax Lite is designed specifically as a cost effective serial modem where standard features of data communications are required. This device is ideally suited for low power (20-30mA at idle) applications and would be the ideal solution when upgrading from 2G to 3G.
The Intelimax Lite has all the essential functionality for todays M2M environment including RS-485 hardware option, extreme operating temperatures (-30° to 85°c) and an SMA antenna for improved signal strength. This compact and economical device is the ideal solution for high volume applications.
MODEM EMULATION WITH INTELIMAX
Modem emulation assists in the transition from Circuit Switched Data (CSD) to Packet Switched Data/IP (PSD). If the control center management system supports IP but the field devices only support dialing back to the control center using CSD, then you can use the Intelimax to emulate the CSD modem interface. The Intelimax can also be configured to act as an IP stack server for incoming connections if necessary.
From the perspective of the field device it will dial out a CSD data call like it always has, except the Intelimax will instead establish an IP stack client connection to the server. For example the field equipment may dial the following string: ‘ATDT0412123456’, then wait for the connection to be established by receiving a ‘CONNECT’ message. The Intelimax can be configured to establish an IP stack client connection to one of several different server IP addresses depending on the number dialed.
The Intelimax must be configured in IP stack auto server or IP stack manual server mode. This configuration can be made using the Intelimax GUI or via AT commands. If the Intelimax is in IP stack manual mode then it will only connect to the network when it receives the ATDT command via serial and will drop the connection when the call is hung up (+++, ATH). If the Intelimax is in IP stack auto mode (server) then it will act as an IP stack server (and therefore could be addressed remotely) until it receives the dial out commands.
The Intelimax modem emulation can be configured using the following AT commands:
To enable modem emulation and add a data number to IP address and port number emulation to the list
To check current emulation list (must have already enabled emulation)
To Enable/Disable Modem Emulation – this must be enabled on the server Intelimax for CONNECT message
To delete a rule from the list
