PCAN-Ethernet Gateway DR

The PCAN-Ethernet Gateway DR allows the connection of different CAN busses over IP networks. CAN frames are wrapped in TCP or UDP message packets and then forwarded via the IP network from one device to another. The PCAN-Ethernet Gateway DR provides one LAN connection and two High-speed CAN interfaces. With its DIN rail casing and the support of the extended temperature range, the module is suitable for use in an industrial environment.

The PCAN-Gateway product family is configured via a convenient web interface. Alternatively, the JSON interface allows access via software. Both options provide status information and settings of the devices, the various communication interfaces, message forwarding, and filters.

• 10/100 Mbit/s bit rate
• RJ-45 connector with status LEDs
  
  

CAN properties

• Two High-speed CAN channels (ISO 11898-2)
• Bit rates from 5 kbit/s up to 1 Mbit/s
• NXP PCA82C251 CAN transceiver
• Galvanic isolation of the CAN channels up to 500 V against each other, against RS-232 and the power supply
• Compliant with CAN specifications 2.0A and 2.0B

With the PCAN-Gateways, CAN busses can be connected via LAN or WLAN. CAN frames are wrapped into TCP or UDP message packets and then forwarded from one device to another. Based on this technology, it is possible to connect CAN networks over a great distance.

The configuration of the PCAN-Gateway product family is done via a convenient web interface. For this, the device must be connected to the PC via LAN or WLAN, depending on the used model. The web interface can be opened with a common browser. After a successful login you get access to all information and the configuration of the device settings, communication interfaces, message forwarding, and filters.

Alternatively, the JSON interface is available for access. This allows the development of software to automatically monitor and configure all devices connected to the IP network.

Functions of the web interface:

• Clear presentation of information about device settings, communication interfaces, message forwarding, and filters
• Definition of the public visibility of status information
• Import and export of device configurations
• Reset of the device configuration to factory defaults
• Comfortable software updates
• Scan of the IP network for further available PCAN-Gateways for an easier establishment of routes
• Layout automatically adjusts for mobile devices
• Rebooting the device via the website
• Enabling, disabling, and configuration of the JSON interface
• Integrated help pages
  
  

CAN channels settings:

• Selection of bit rates up to 1 Mbit/s from a preset list
• Setup of user defined bit rates via register values
• Status switching of the listen-only mode
  
  

LAN interface settings (if available):

• Automatic or manual setup of the device‘s IP address (IPv4) and the subnet mask
  
  

WLAN interface settings (if available):

• Set the WLAN operating mode to Infrastructure (Client), Ad-Hoc, or Access Point
• Automatic or manual setup of the device‘s IP address (IPv4) and the subnet mask
• Connection to the wireless network
• Configuration of the network encryption
  
  

Setup and management of the message forwarding:

• Setup of the message forwarding between a CAN channel and LAN/WLAN (or vice versa)
• Selection of the participating CAN channel
• Definition of the LAN/WLAN station according to the IP address and the port
• Selection of the transfer protocol TCP or UDP
• Enabling, disabling, and editing of existing routes
• Disabling the PCAN-Gateway Handshake to allow the connection to other devices
  
  

Properties of the message filtering:

• Creating and managing filters via a new section of the web interface
• Creating Filters with different options:
• Filtering messages with 11-bit or 29-bit IDs
• Support of range and mask filters
• Optional inversion of the filter range
• Assigning a filter to multiple routes
  
  

Functions of the JSON interface:

• Receiving of a request as a JSON-formatted GET parameter of an HTTP request
• Returning of the response in JSON format
• Reading out authorized information about device settings, communication interfaces, message forwarding, and filters
• Configuration of settings as well as adding and deleting message forwarding and filters (function is deactivated at delivery)
• Alternative access to the JSON interface via an emulated shell view with integrated documentation for an easy start

• PCAN-Ethernet Gateway DR in DIN rail plastic casing
• Mating connectors for both CAN channels, RS-232, and power supply
• RJ-45 network patch cord (2 m)
• Manual in PDF format
• Printed quick start guide
