SKU: WU-12-20-41x-20 Categories: ,

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.

Key Product Features

    • Optional (HS/LS) build can be special ordered for interfacing between high speed and low 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
    • Code compatible supported across CG-ARM7, CG-ARM7/GTI, and CG-ARM7/D/E CAN Gateway family
    • Configuration and firmware download via RS-232 interface
    • Optional configuration and firmware download via CAN Bus (requires use of CPC PC interface)
  • 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 RS232 interface. Download software for the configuration is available for Windows and Linux PCs.

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:

  • 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

Specifications

Layout and Connection

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.

What type of RS-232 Cable is required for configuration, straight through or null modem?

Answer: The CG-ARM7 RS-232 interface is configured as a DTE port (RxD is on Pin 2 of DB9 connector). A null modem cable is required if the R-232 interface of the connected PC is also configured as a DTE port (usually the case for PCs, and also usually the case for USB based RS-232 adapters).

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.
