Introduction
This document describes the features and objectives of the CAN-Ethernet gateway AnaGate CAN quattro.
This device is part of a product line, whose single devices only differ in the number of CAN interfaces
and/or the device case.
In this manual the term AnaGate CAN Gateway is uniformly used, if no specific modell is addressed or it
is not necessary to differentiate. Otherwise the full product name is used, like AnaGate CAN uno, AnaGate
CAN duo or AnaGate CAN quattro.

Chapter 1. Description
The AnaGate CAN Gateway connects a PC, an embedded PC or other general device one or more CAN
busses via the TCP/IP network protocol. It basically works as a CAN master with no own CAN identifier
on the bus.
Controlling and configuration of an AnaGate CAN Gateway is made through TCP/IP. The application
protocol itself is described in detail (see [TCP-2010]). Thus the access to the device can be programmed
via native calls to the TCP/IP socket interface. This means that any communication partner with a LAN
interface is able to communicate to the device. Accessing the AnaGate CAN Gateway with the supplied
application libraries for Windows and Linux are much comfortable and can be used with conventional
programming languages.
In bridge mode the AnaGate CAN Gateway can interconnect two physically independent CAN networks
via LAN/Ethernet (LAN bridge mode). With the coupling over LAN/Ethernet it is possible to connect
separate CAN buses with different baud rates over long distances.
Note
The AnaGate CAN duo and AnaGate CAN quattro can additionally interconnect two internal
CAN interfaces (internal bridge mode).
1.1. Features
• The AnaGate CAN quattro can send and receive CAN messages via its four existing CAN interfaces
independantly. This can be done using a device that supports TCP sockets (like a personal computer
or a PLC).
• Variable CAN bus speed per interface (10, 20, 50, 62.5, 100, 125, 250, 500, 800 or 1000 kbps).
• Software configurable bus termination for each CAN interface.
• Two different plugs for voltage supply.
• System is addressed using a proprietary network protocol.
• Static or dynamic assignment (DHCP) of IP address.
• 4 digital inputs and outputs, which can be accessed via LAN/Ethernet (except AnaGate CAN USB and
AnaGate CAN uno (DIN rail)).
• Several simultaneous network connections (4x TCP and 1x UPD) are supported on each existing CAN
interface.
• Coupling of two independent CAN networks via the LAN/internet via a LAN bridge over two seperate
devices. All devices of the AnaGate product line except the AnaGate CAN USB support this feature.
• Coupling of two independent CAN networks via the internal CAN/CAN bridge (only AnaGate CAN
duo and AnaGate CAN quattro).

Chapter 2. Configuration
2.1. Initial installation
First the AnaGate CAN Gateway must be supplied via the power plug with a tension from 9 to 24 V.
Insert the included LAN cable into the plug labelled LAN and connect it either to a hub or switch. If
connecting to a PC use a crossover LAN cable (not in scope of delivery) instead of the included LAN cable.
The AnaGate CAN Gateway is delivered with the following initial network settings:
IP address 192.168.1.254
Address type static
Network mask 255.255.255.0
Gateway 192.168.1.1
The device can now be configured using a standard browser (Internet Explorer, Firefox, etc.) by using
http://192.168.1.254.
Figure 2.1. HTTP interface, AnaGate CAN uno
Note
The PC used for the configuration must be in the 192.168.1.x network. The static
IP address 192.168.1.2 with the subnet mask 255.255.255.0 can be e.g. used. If
neccessary the settings of the network interface on the configuration pc has to be changed
temporarily.

Configuration

2.2. Network settings
On the page IP Settings the following settings can be changed.
DHCP Here you can switch between static IP and dynamic (via DHCP) addresses. If DHCP
is being used, the remaining fields are ignored, because this information is retrieved
from the DHCP server.
In this case, a DHCP server must be available and accessible in the network.
IP address The IP address of the AnaGate CAN Gateway is entered in a.b.c.d format (e.g.
192.168.1.200).
Subnet mask The subnet mask is entered in a.b.c.d format (e.g. 255.255.255.0).
Gateway The default gateway is entered in a.b.c.d format (e.g. 192.168.1.1). Leave blank or
enter 0.0.0.0 if a default gateway is not required.
Figure 2.2. HTTP interface, network settings
The inputs will be taken over immediately after clicking the button Save settings and saved
permanently on the AnaGate CAN Gateway. A restart of the device is not necessary for activation of the
settings.
Note
Maybe the ARP cache of the PC has to be deleted to find the device with the changed IP
address.
2.3. CAN settings
On the page CAN Settings the global settings for all existing CAN interfaces are displayed and can be
changed individually.

2.4. Functional extensions based on LUA
On a AnaGate CAN quattro it is possible to execute self-created applications with an installed LUA script
interpreter (see [Prog-2010] for a detailed description of all programming features).
On the page LUA LUA script files can be downloaded to the device and executed locally.

execution can be cancelled.
Available scripts Displays all scripts which are currently available on the device.
To start the execution of a script click on the button Start. Via button
Delete a script can be deleted on the device and via Boot a script can be
defined as boot script.
script output area In this text area the standard output (stdout) of the currently executing script
is displayed. Via the button Clear this text area can be cleared.
error output area In this text area the standard error output (stderr) of the currently executing
script is displayed. Via the button Clear this text area can be cleared.
Tip
The text areas for script and error output are not refreshed automatically. A manual page
reload of the current page refreshes both text areas.
2.5. Digital IO
Over the 10-pole pin row on the back of the AnaGate CAN Gateway four digital inputs and four digital
outputs are led out, which can be used freely. Since the IO's are electrically isolated from the AnaGate
CAN Gateway, they must be separately supplied via the pins 1 us 2 with a voltage by 3,3V - 24V DC.
Figure 2.5. Pin layout, digital IO plug
2.5.1. Connecting the digital inputs
At the inputs IN1 to IN4 any external voltage between VCC and GND can be applied. As soon as the
voltage difference between INx and GND is more than 1.0 V, the AnaGate CAN Gateway interprets the
input as logically HI otherwise LOW.

Configuration
10 © 2007-2010 Analytica GmbH
2.5.2. Connecting the digital outputs
The outputs are implemented as open collector drivers. If a output is active, it is pulled down to GND. In
the inactive condition the output is floating.
In principle the maximum current of each individual output is 400mA. For thermal reasons is the sum
of all output currents is limited to 500mA. The outputs not short-circuit proofed, and must be protected
with a pre-resistor.
2.6. Firmware update
Use the Firmware page to load a new firmware to the AnaGate CAN Gateway.
Please visit our Web site http://www.anagate.de for further information.
2.7. Factory reset
In order to restore the default factory settings, hold the RESET for approx. 10 seconds. If the device is
reset successfully, the yellow LED blinks until the RESET is released.
The default factory settings are activated immediately without a restart of the device:
IP address 192.168.1.254
Address type static
Network mask 255.255.255.0
Gateway 192.168.1.1
Important
If the RESET push-button is pressed too briefly, the actual IP address and network mask
is pulsed via the yellow LED (Morse code). A second push of the RESET, terminates the
pulsing, the device is not reset.
Note
The factory reset is not possible directly after power on until complete loading of operating
system and firmware of the device. This initialization period is signalled via the yellow
activity LED. On power on the LED is switched on and after initialization the LED is
switched off.
Note
Maybe the ARP cache of the PC has to be deleted to find the device with the changed IP
address.
2.7.1. Examining the network settings
It is possible to check the current network settings directly on the device.
After pressing shortly the RESET button the device starts to pulse out the current n settings via the yellow
activity LED. Pressing again the buttons stops the pulsing immediately.
The IP address and subnet mask are pulsed out, one after the other. Following pulse codes are used:

Configuration
11 © 2007-2010 Analytica GmbH
• Digits 1, 2, 3, ...., 9: 1x, 2x, ...9x Flashing (200ms delay between each flash)
• Digit 0: 10x flashing (200ms delay between each flash)
• Dot: 1x very fast flash
Between two single digits a delay of 1 seconds is made, and between the IP address and subnet mask two
fast flashes are pulsed out.

Chapter 3. Fields of application
If the AnaGate CAN Gateway is connected to the CAN bus, mind the following facts:
•CAN_L: This line has to be connected to the CAN_Low line of the CAN bus.
•CAN_H: This line has to be connected to the CAN_High line of the CAN bus.
•GND: This line can be connected optionally to GND of the other bus devices.
3.1. Gateway mode
In gateway mode the CAN messages are transferred transparently over TCP/IP between the CAN network
and the host platform (e.g. PC) in both directions. The AnaGate CAN Gateway uses no unique CAN ID
when sending telegrams, this ID has to be set explicitly for each transmitted message.
All CAN messages received by the device are transmitted to all active LAN-connected host systems. It
is possible to discard all incoming messages in general or to set individual software filters to reduce the
message traffic to the host systems.
Figure 3.1. AnaGate CAN Gateway in gateway mode
• The software program CAN Monitor, which is included on the documentation CD, can be used to
monitor a CAN bus or to create single CAN telegrams.
• Application programs, which are using the included software API inteface.
• Self-created batch files which are executed via the included LUA interpreter with integrated AnaGate
software API.

Fields of application

3.2. Bridge mode
In the bridge mode two arbitrary CAN networks can be interconnected by two AnaGate CAN Gateways.
The CAN messages are exchanged transparently over TCP/IP between the two devices.
It is possible to mix the different AnaGate CAN Gateway models in bridge mode.
Important
It is recommended to use unique CAN identifiers in the interconnected CAN networks.
Via HTTP interface both AnaGate CAN Gateway are configured as usual.
Subsequently one of the two devices has to be configured for the bridge mode. This can be done by the
page CAN Settings of the web interface (see Section 2.3, “ CAN settings”). This device acts in a manner of
speaking as master and establishes the network connection to the second device and manages connection
control. Basically a bridge can be created for each existing CAN interface of the device.
Figure 3.2. AnaGate CAN Gateway in bridge mode
The following additional parameters can be set for the device:
• IP address of the partner device, which is to be connected.
• CAN port of the partner device, which is to be connected.
• Thebaudrate of thepartner device. Thebaudrate of theparter device isindependant of theown baud rate.
• The internal termination resistor is to be set on/off for the CAN port of the parter device.
WhentheAnaGateCANGatewayestablishestheconnectiontothepartnerdevicesuccesfully,thespecified
baud rate and integrated termination option is automatically set on the partner device.

Fields of application
14 © 2007-2010 Analytica GmbH
Note
On the models with more than one CAN interface, it is possible to interconnect one CAN
interface to another interface of the same device (this is called internal bridge).
To interconnect the two CAN interface on a single device, the own IP address or
127.0.0.1 has to be used. In this case the specified remote baud rate and termination is
used on the interconnected interface.
