The CAN/CAN gateway CG-ARM7/GTI transmits CAN signals between subsystems. CG-ARM7/GTI allows a flexible design of the wiring topology. Star and tree structures as well as extensive line structures can be realized. The galvanic separation between the CAN channels allows the use with diverging ground potentials.
The CG-ARM7/GTI obtains its potential through the use of a 32 bit microcontroller with 48MHz clock. Among the available functions are data rate adaption, 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/GTI.
Device configuration is conducted using a PC, via CAN if also using any of the CPC Series PC Interfaces (PCI Express, USB, or Ethernet are supported) or through the built-in RS232 interface. Download software for the configuration is available for Windows and Linux PCs. The CG-ARM7 is also available in version HS/LS, allowing for the conversion of high speed to low speed CAN.
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:
Both CAN busses are connected by a D-Sub 9 male connector. Also the power supply and the RS232 interface have D-Sub 9 male connectors.
|Voltage on bus connectors||-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 onCG-ARM7/GTI 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)||n.s.||40||n.s.||mA|
All values, unless otherwise specified, refer to a supply voltage of 24V and an environmental temperature of 20°C.
