Communication gateway CG-ARM7

RS232CAN

Description The rail mountable CAN/CAN gateway CG-ARM7 transmits CAN signals between subsystems. CG-ARM7 allows a flexible design of the wiring topology. Star and tree structures as well as extensive line structures can be realised. 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. CG-ARM7 obtains its potential through the use of a 32 bit microcontroller with 48MHz clock. High speed processing and low latencies allow the use with high data rates and busloads. Cost efficient series applications are particularly promoted by use of CG-ARM7. The configuration of the device functions can take place either through CAN or through the built-in RS232 interface. Download software for the configuration is available for Windows PCs as well as Linux PCs. CG-ARM7 is available in version HS/LS allowing the conversion of high speed to low speed CAN. For special tasks, like modification of the data content of the CAN messages, we over a development kit to write custom specific firmware for CG-ARM7. Special Features CAN/CAN-Gateway CG-ARM7 Connection of CAN subnetworks with differing data rates Filtering and buffering of data traffic Support of 11 bit and 29 bit identifiers Increase of the system extension Microcontroller NXP LPC2119 with 2 internal CAN controllers
