CAN Bus Gateway
The CG-ARM7/D/E is a CAN Bus Gateway designed for applications where there is a demand for higher flexibility. Both the supply voltage range and the operating temperature range are extended in a way that the use in automotive applications is possible.
With the development kit and the ability to use its USB interface to configure the device, to download new firmware and to supply power, CG-ARM7/D/E performs as a versatile development platform for CAN/CAN gateway applications.
Firmware which has been developed on this device can also be run on CG-ARM7 and CG-ARM7/GTI. Among the available functions of the standard firmware are data rate adoption, message filtering as well as identifier conversion between the coupled busses.
The restriction of the maximum data rate depending on cable length for single CAN segments can be abolished for the over-all system by use of CG-ARM7/D/E. CG-ARM7/D/E obtains its potential through the use of a 32 bit micro controller with 48MHz clock. High speed processing and low latencies allow the use with high data rates and bus loads.
For special tasks, such as modification of the data content of CAN messages, a development kit with the CG-ARM7/D/E design variant is optionally available for writing custom specific (ARM7) firmware. A range of code compatible CPC-ARM7 design variants are available, with the following differentiating features:
The connection of the CAN bus is done by a D-Sub 9 male and female plug. These are also used as default power supply connection. An USB interface is provided for configuration, firmware download and optional power supply purposes.
|Voltage on bus connections||-30||+30||V|
|Admissible power consumption (at 60°C)||n.s.||2000||mW|
Any (also temporary) stress in excess of the limiting values may cause permanent damage on CG-ARM7/D/E and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
|Current consumption (running idle)||-||tbd||-||mA|
All values, unless otherwise specified, refer to a supply voltage of 24V and an environmental temperature of 20°C.
