The RabbitCore® RCM3900 module series delivers 10/100Base-T Ethernet and -20°C to +85°C extended temperature range. The RCM3900 series offers two variations, one with on-board 32MB of flash memory mass storage, and the other version without it. Both variations deliver the capability to use up to 1 GB of hot-swappable mass storage with miniSD™ memory cards, ideal for embedded applications using data archiving for later uplink to a computer.
Device Manager is a feature of all Digi cellular gateways, routers, devices and components. Device Manager provides a robust suite of network management tools including authentication, configuration management, account management, asynchronous updates and alerts, group and individual software updating, network data storage and gateway programming.
Device Manager empowers IT, network operations and customer support organizations to conquer the challenges of managing the vast array of cellular equipment in their device networks. Network managers can remotely configure, upgrade, monitor and troubleshoot remote devices, and create applications that improve productivity, speed and efficiency.
Applications that can use the mass storage and Ethernet capability of the RabbitCore RCM3900 module are:
The RCM3900’s mass-storage can use the Dynamic C software FAT file system module to store data and use the same directory file structure commonly used on PCs.
RabbitCores mount directly onto a user-designed motherboard and act as the controlling microprocessor for the system. Its compact size - 1.85" x 2.73" x 0.86" (47 mm x 69 mm x 22 mm) – makes it easy to integrate the RCM3900 module onto a motherboard. The RCM3900 has fast program execution SRAM and data SRAM, flash memory, and the circuitry necessary for reset and management of battery backup of the Rabbit 3000’s internal real-time clock and the data SRAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports, and serial ports.
The RabbitCore family of microprocessor core modules is designed to facilitate rapid development and implementation of embedded systems. Develop programs with our industry-proven Dynamic C® development system, a C-language environment that includes an editor, compiler, and in-circuit debugger.
Download the program from your PC via USB or serial port, and debug right on the target hardware – no in-circuit emulation is required. This environment reduces effort and speeds hardware and software integration. Rabbit provides an extensive library of drivers and sample programs, along with royalty-free TCP/IP stack with source.
A Development Kit provides the essentials that you need to design your own microprocessor-based system, and includes a complete Dynamic C software development system. The Development Kits also contains a Prototyping Board that will allow you to evaluate the RCM3900 module and to prototype circuits that interface to the module. You will also be able to write and test software for the RCM3900 modules.
