The CG-ARM7/D/E is a CAN Bus to 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.

  • The 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.
  • A benefit of using a CG-ARM7 CAN Gateway is that the restriction of the maximum data rate depending on cable length for single CAN segments can be abolished for the over-all CAN system.

The CG-ARM7/D/E is delivered with standard firmware that supports a variety of ready to use functions, including: data rate adaption, message filtering and message identifier conversion between the coupled busses.

Key Product Features

  • CAN Gateway for Commercial, Business, and Industrial applications
  • Connection of CAN subnetworks with differing data rates
    • Default (HS/HS) build connects two high speed subnetworks with support for differing data rates
    • Optional (HS/LS) build can be special ordered for interfacing between high speed and low speed CAN subnetworks
    • Optional (LS/LS) build can be special ordered for interfacing between ow speed CAN subnetworks
  • Filtering and buffering of data traffic
    • Ready to use firmware allows configuration to filter and/or map messages by identifier
  • Protocol Infrastructure:
    • Supports CAN protocols 2.0A (11-bit identifiers) and 2.0B (29-bit identifiers)
    • Suitable for use with CANopen, DeviceNet, and J1939 Higher Layer Protocols
  • Microcontroller NXP LPC2119 with 2 internal CAN controllers
  • Extended supply voltage range
  • Extended temperature range
  • FCC Class A Verified: Use is restricted to commercial, business, and industrial environments

Supporting Software

The configuration of the device functions can take place either through CAN or through the built-in USB interface. Download software for the configuration is available for Windows and Linux PCs.

A range of code compatible CPC-ARM7 design variants are available, with the following differentiating features:

  • CG-ARM7/RMD (rail mountable; non-isolated; HS/HS, HS/LS speed options; RS-232 configuration port)
  • CG-ARM7/GTI (rail mountable; galvanic isolation; HS/HS, HS/LS speed options; RS-232 configuration port)
  • CG-ARM7/D/E (firmware re-programmable / recommended for development; included with development kit; HS/HS, HS/LS, LS/LS speed options; USB configuration port; extended temperature operation)

HS = High speed; LS = Low speed


Layout and Connection

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.

Limiting Values

Storage temperature-40+80°C
Operating temperature-40+70°C
Supply voltage-40+35V
Voltage on bus connections-30+30V
Admissible power consumption (at 60°C)n.s.2000mW

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.

Nominal Values

Current consumption (running idle)tbdmA
Supply Voltage62430V

All values, unless otherwise specified, refer to a supply voltage of 24V and an environmental temperature of 20°C.

The CG-ARM7 Control Center is a windows-based software utility for configuring CG-ARM7 CAN Bus Gateways with parameters used to specify the baud rates, filtering and identifier conversion rules to be used. It is included in the scope of delivery for all CG-ARM7 gateways.

Depending on the CG-ARM7 being used, the CG-ARM7 Control Center will configure the gateway via USB, RS-232 or CAN Bus. Configuration via CAN requires the gateway to be pre-configured via RS232 to assign specific CAN message identifiers for configuration via CAN, and also requires the use of a CPC-USB/ARM7, CPC-USB/embedded, or CPC-PCIe.
