Introduction
The Virtual PCAN-Gateway software package provides access for
Windows computers to devices of the PCAN-Gateway product line
over IP-based networks. Various LAN and WLAN network adapters
can be used.
Analog to the bidirectional connection of two PCAN-Gateways,
message forwarding with so-called routes must be set up between
the hardware and the software. At first, two routes have to be
created on the configuration website of the hardware, one for
sending and another for receiving. Then, the appropriate counterparts of these routes must be established within the configuration
software.
Due to this connection, the PCAN-Gateways are being integrated in
the established PCAN environment and can be used like a
customary PEAK CAN interface. For example, the traffic on the CAN
channels can be displayed and traced by the PCAN-View CAN
monitor.
The Virtual PCAN-Gateway supports only Windows 8.1, 7, and Vista
(32/64-bit).

Manage Routes
On the page Routing > Manage Routes the message forwarding
instances are listed with basic information and control options. For
each of these, the status, used transmission protocol, as well as the
source and destination are specified.
Status LEDs: The LED indicates the status of a route.
Status-LEDs
Meaning
The route is inactive.
The route is active and connected with the remote site.
Warning! The route is active but not connected with the remote
site.
The selected network adapter is initializing. Afterwards the route
is automatically started.
The selected network adapter may not be available.
Source / Destination: The source and the destination depend on the
direction of the message forwarding.
Note: At the Virtual PCAN-Gateway "Local PCAN-LAN"
represents a CAN channel of the connected PCAN-Gateway.
Protocol: Routes can use TCP or UDP as the transmission protocol
in the IP network.
TCP (Transmission Control Protocol) establishes a connection
between two subscribers and monitors their communication. If data
packets are lost for example, they are retransmitted.
7
Virtual PCAN-Gateway – User Manual
UDP (User Datagram Protocol) sends the data packets directly into
the network without establishing a connection. With this protocol,
error free transmission is not guaranteed. The advantage UDP has
over TCP is the lower demand on performance.
Control Elements:
The control elements are always related to the currently selected
route. Click on the row of the corresponding route to select it.

On the Routing > Add Route page you can set up a new route.
Editing a route is done via the page Routing > Manage Routes.
Regardless of their status up to 8 routes can be created. Then the
Add Route function is no longer available.
Route Direction:
When you create a route, you should start with the selection of
direction since the following input and output fields are determined
by this.
Receive IP > PCAN-LAN: In a Receive-Route the Virtual PCANGateway receives the message of a CAN channel from a PCANGateway hardware via the IP interface.
Send PCAN-LAN > IP: In a Send route CAN messages are forwarded
over the IP interface to a CAN channel on a PCAN-Gateway
hardware.
Note: At the Virtual PCAN-Gateway "Local PCAN-LAN"
represents a CAN channel of the connected PCAN-Gateway.
Status:
Use this setting to determine the state of the route after it is created.
Ticking the checkbox will have the effect of immediately activating
the route after the completed form is saved.

Virtual PCAN-Gateway – User Manual
Network Adapter: Select from the drop-down list one of the
available network adapters. The adapter is used for the IP
communication of this route.
IP Interface:
IP Address: Enter the IP address (IPv4) of the destination device. It
should be noted that only values from 0 to 255 may be used and
certain address ranges are reserved.
In the first field, enter a value less than 224, since addresses
starting from this value are reserved for Multicast messages
Depending on the Subnet mask, the highest device address is
reserved for broadcast messages. For the Subnet mask
255.255.255.0 and the network address 192.168.1.xxx, the
reserved address would be: 192.168.1.255
Depending on the Subnet mask the lowest device address is
reserved for messages that are addressed to the entire network.
For the Subnet mask 255.255.255.0 and the network address
192.168.1.xxx, the reserved address would be: 192.168.1.0
Note: For Receive routes the IP address is automatically set to
the selected network adapter.
Port: Enter a port between 1024 and 65535. Values below 1024 are
reserved for various system services and must therefore not be
used.
Protocol: Select which transmission protocol should be used by the
route in the IP network.
TCP (Transmission Control Protocol) establishes a connection
between two subscribers and monitors their communication. If data
packets are lost for example, they are retransmitted.
10
Virtual PCAN-Gateway – User Manual
UDP (User Datagram Protocol) sends the data packets directly into
the network without establishing a connection. With this protocol,
error free transmission is not guaranteed. The advantage UDP has
over TCP is the lower demand on performance.
Note: Any combination of the IP address, port, and protocol can
only be used once.
Finally you can create a new route with the Add Route button.
Note: Transferring data between a Virtual PCAN-Gateway and a
PCAN-Gateway always consists of a Send and a Receive route
per CAN channel to be connected. Note that the Send and
Receive route, which belong together, should use the same
transmission protocol (TCP or UDP) and the same port.

Export: With the Export button you can download the
current device configuration of the device and the defined
routes in form of a (*.ini) file.
To create the corresponding mating routes automatically with the
software, proceed as follows:
1.
Open the software Virtual PCAN-Gateway and go to the
page Device > Configuration. At this page different import
and export options of the software configuration are
available. There is also an option for importing a configuration file of a PCAN-Gateway.
2.
Importing a device configuration: With the Join button
you can import the configuration file (*.ini). For each Send
route stored in this file a appropriate Receive route will be
created and vice versa.
After importing, the routes will be displayed in the overview on the
page Routing > Manage Route of the Virtual PCAN-Gateway.
If all routes are created and active, you can access and use the
connected CAN channel like a normal CAN interface from PEAKSystem with your PC. In the following chapter, this is illustrated
with the monitor software PCAN-View.
