Description
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.Ordering information

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.
Pin | Name | Function |
1 | +24 V | Supply voltage |
2, 3, 6 | GND | Ground |
4 | CAN1_H | CAN1 signal line (dominant high) |
5 | CAN1_L | CAN1 signal line (dominant low) |
7 | CAN2_H | CAN2 signal line (dominant high) |
8 | CAN2_L | CAN2 signal line (dominant low) |
Limiting Values
Parameter | Minimum | Maximum | Unit |
Storage temperature | -40 | +85 | °C |
Operating temperature | -20 | +85 | °C |
Supply voltage | -100 | +35 | V |
Voltage on bus connections | -30 | +30 | V |
Admissible power consumption (at 60 °C) | n.s. | 2000 | mW |
Any (also temporary) stress in excess of the limiting values may cause permanent damage on CG-ARM7 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
Parameter | Minimum | Typical | Maximum | Unit |
Current consumption (running idle) | n.s. | 40 | n.s. | mA |
Supply voltage | 10 | 24 | 30 | V |
All values, unless otherwise specified, refer to a supply voltage of 24 V and an environmental temperature of 20 °C.
