is rail mountable CAN/CAN gateway, which transmits CAN signals between subsystems.

Special Features


  • 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
  • Powerful Cortex M3 microcontroller with internal CAN controller
  • Galvanic separation between the CAN channels
  • Rail mountable



The rail mountable CAN/CAN gateway CG-ARM7/GT transmits CAN signals between subsystems. CG-ARM7/GT 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/GT. The galvanic separation between the CAN channels allows the use with diverging ground potentials.CG-ARM7/GT obtains its potential through the use of a 32 bit microcontroller with 96 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/GT.The configuration of the device functions can take place either through CAN or through the built-in RS232 interface. CG-ARM7/GT can be deliverd with a customer specific baudrate configuration. Download software for the configuration is available for Windows PCs as well as Linux PCs.

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.

1+24 VSupply voltage
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)

Limiting Values

Storage temperature-40+85°C
Operating temperature-20+85°C
Supply voltage-100+35V
