  • Filtering and buffering of data traffic
  • Support of 11 bit and 29 bit identifiers
  • Increase of the system extension
  • Microcontroller NXP LPC2119 with two internal CAN controllers
  • Version HS/LS with one transceiver PCA82C251 and one transceiver TJA1054
  • Rail mountable

 

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 realized. 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 48 MHz 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 and is within the scope of delivery.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.

Technical Data

Layout and Connection

The connection to the CAN busses is achieved via pluggable terminals. Besides the CAN signals the clamps also carry the supply voltage for CG-ARM7.
The following table shows the pin assignment of the internally connected interfaces.

PinNameFunction

2, 3, 6GNDGround
4CAN1_HCAN1 signal line (dominant high)
5CAN1_LCAN1 signal line (dominant low)
7CAN2_HCAN2 signal line (dominant high)
8CAN2_LCAN2 signal line (dominant low)
