CAN-to-WLAN gateways with two high-speed CAN ports

Peak (Germany) complements its gateway product family by two WLAN-enabled devices. The introduced products are based on Freescale’s iMX257 ARM9 micro-controller.

FOR THIS, CAN FRAMES ARE WRAPPED in TCP or UDP message packages and forwarded from one device to another over the IP network. The PCAN Wireless gateways are supplied in a plastic housing with a flange and are available in two versions: One with two 9-pin D-Sub connectors (compliant with the CiA pinning) and the other with a 12-pin Tyco automotive connector. Built in are two CAN channels with a bit-rate of up to 1 Mbit/s (ISO 11898-2).

The WLAN interface supports IEEE 802.11 b/g and establishes its connection via an internal chip antenna. Thanks to its extended operating temperature range of -40 °C to 85 °C the gateway is suitable for use in industrial and automotive environments. Configuration of the devices is provided through a web interface. Besides a variety of status information, settings for the device itself, for the communication interfaces, and for message routing are provided.
The gateway features a wake-up function using a CAN network or a separate input.

The Network page of the configuration software displays for each CAN channel the status, the bit-rate, and the setting of the listen-only mode. Furthermore status information can be viewed, and user defined notes can be entered and saved. With a button the user can reset the CAN channel. Of course, the WLAN interface is also configurable by means of this web-based software.
