EtherCAN MC is designed for mobile analysis of CAN systems. It is suited for use in systems where more than one CAN has to be tracked (i.e. automotive applications).
Further features of EtherCAN MC are the integrated power management, an ethernet and a serial interface.
The power management allows low power consumption, when all peripherals of the CPU are in sleep mode or are powered down. Nevertheless a wake up CAN message will not be lost.
A WLAN adapter may be connected to the ethernet interface and a GSM modem to the serial interface (RS232). The device has a 32bit microcontroller (ARM7 core), embedded Linux operating system and 6 CAN channels (4 high speed, 2 low speed), all equipped with NXP SJA1000 CAN controller.
An application development kit for creation of custom applications is included.
The 6 CAN channels, the I/O pins and the power supply are all on a male DSUB-25 connector. The following table shows the connection schema.
| Pin | Name | Function |
|---|---|---|
| 1, 13, 22 | GND | Ground line |
| 2, 14 | CAN_L 0, CAN_H 0 | CAN Channel 0 (high speed CAN) |
| 3, 15 | CAN_L 1, CAN_H 1 | CAN Channel 1 (high speed CAN) |
| 4, 16 | CAN_L 2, CAN_H 2 | CAN Channel 2 (high speed CAN) |
| 5, 17 | CAN_L 3, CAN_H 3 | CAN Channel 3 (high speed CAN) |
| 6, 7, 18, 19 | CAN_L 4, CAN_H 4, RTL_4, RTH_4 | CAN Channel 4 (low speed CAN) |
| 8, 9, 20, 21 | CAN_L 5, CAN_H 5, RTL_5, RTH_5 | CAN Channel 5 (low speed CAN) |
| 10 | +5V_EXTERN | Power output +5V/600mA (switchable) |
| 12 | WAKE_EXTERN | Input (+12V DC) for external wake up signal |
| 24 | DO_HS | Digital output, high side switch |
The RS232 male plug is connected as shown in the following table.
| Pin | Name | Function |
|---|---|---|
| 2 | RxD | Data line receive |
| 3 | TxD | Data line send |
| 5 | GND | Ground line |
| Parameter | Minimum | Typical | Maximum | Unit |
|---|---|---|---|---|
| Current consumption ( +12V) | – | 170 | – | mA |
| Current consumption stand by ( +12V) | – | 15 | – | mA |
| Supply voltage | 8 | 12 | 30 | V |
| All values, unless otherwise specified, refer to an environmental temperature of 20°C. | ||||
