The ZULU range of GPRS modems are amongst the most advanced and capable modems available today. The range is available as two main versions - with or without GPS. Further options include an upgrade of flash memory to a total of 128Mbit. The ZULU range can be used as a simple modems, or with application software within the GPRS module. But its real strength, for the user, is as a comprehensive computing platform using its ARM Cortex M4 32bit processor connected to the GPRS engine - all in one package. The ZULU design has been extensively tested and represents amazing value as a GPRS connected powerful 32bit computing engine.
The ZULU modems have an ARM Cortex M4 32bit processor as standard, independent of the wireless module, for customers to develop their software on. The ZULU has both USB and RS232 serial ports with 10 GPIO lines as standard. The ZULU is housed in a tough plastic enclosure that is either screw or DIN rail mountable.
The ZULU-G-GPRS is the GPRS version with GPS capability.
The ARM Cortex M4 32bit processor manages the Telit module and is available for the user to program to their custom application. The features of the standard ZULU are as below:
All connections to all interfaces of the modems can be made through the 36 way connector with the exception of the antenna(s) and USB. The ZULU also has a separate Mini USB and RS232 socket, and an RJ12 power socket. The status of the ZULU is shown by three easily viewable LEDs all of which are ultimately programmable to the user's needs.
ARM Cortex M4 32bit Processor
The ZULU is driven by the ARM Cortex M4 32bit processor which has 192KB of RAM and 16Mbit of flash memory for customer use, which is expandable to 128Mbit. The ARM Cortex M4 32bit processor is a popular and well known microcontroller with a considerable amount of code already written for it. The ARM Cortex M4 32bit processor ‘Discovery Board’ is also a popular development platform and has considerable documentation to help with code development.
The ZULU itself can emulate the ‘Discovery Board’ and therefore be used in this mode for easy code development by the customer, similar to a standalone Discovery Board. The ARM Cortex M4 32bit processor is a very low power micro and within the ZULU consumes around 50mA when fully loaded and running. Conversely it can be put into deep sleep thereby taking a few microamps. The processor itself is capable of considerable multithreading with a number of layers of software. Most of the above interface attributes of the ZULU are native to the ARM Cortex M4 32bit processor and will be a known quantity to anyone familiar with the STM32 processor family.
Additionally the ZULU has an integral accelerometer and features an ignition line, modem control and reset lines on the RJ12 connector making it very suitable for a vehicle tracking and control unit, with a small amount of microcontroller software design. The 600mA solid state relay is also a standard feature of the ZULU range and is accessible via the 36 way connector. The ZULU series is packaged in a tough blue ABS plastic box that is DIN rail or screw mountable and has dimensions of 134 x 74 x 33mm. In all the ZULU is designed to be your M2M modem and main computing engine in one package using a well understood and very capable microcontroller range that is easy to program with.
The ZULU modem range has been designed for long life and is available in UMTS and GPRS form with LTE coming very shortly - all with the same design and features making it easy for the user to design once, and use the many versions with very little effort.
The ZULU range has a number of accessories available:- JTAG programming cable, OEM power cable, 0.5M and 1M 36way cable and connector with unterminated ends, and 12V wallblock power supply with RJ12 connector.
See ZULU Accessories for the full range of accessory products for the ZULU-G-GPRS including power supply, power cable and interface cables.
Evaluation and Development Board
The ZULU-EVK evaluation and development board is the perfect way of working with the ZULU modems, and developing an application within the ARM Cortex processor. The EVK provides simple and convenient access to the ZULU interfaces through standard D-Sub and modem block connectors.
The ZULU-EVK board also comes complete with a multi region power supply, 36way interface cable, RS232/USB cables, a JTAG programming cable, our Delta 2A GSM antenna and the Mike 3A GPS antenna, providing all the components for a working system - just add your choice of ZULU modem.
