Introduction
This document describes the functionality and features of the CAN FD-Ethernet
gateway AnaGate CAN FZ16C4.
This device is part of a product line, whose single device types mostly differ in the
number of CAN interfaces and/or the device case. The differences are described by
referring to a specific device in the series.
In this manual the term AnaGate CAN Gateway is uniformly used, if no specific model
is addressed or it is not necessary to differentiate. Otherwise the full product name
is used, such as AnaGate CAN USB, AnaGate CAN uno, AnaGate CAN duo, AnaGate
CAN quattro, AnaGate CAN X2, AnaGate CAN X4, AnaGate CAN X8, AnaGate CAN
FX2, AnaGate CAN FX4, AnaGate CAN FZ8, AnaGate CAN FX8, AnaGate CAN FZ16,
AnaGate CAN FZ16C4, AnaGate CAN F2, AnaGate CAN F4 or AnaGate CAN F8.

Chapter 1. Description
The AnaGate CAN Gateway connects a PC, an embedded device or other general
devices to one or more CAN buses via the TCP/IP network protocol. It can function
both as an active CAN bus participant and as a passive receiver.
For this purpose, the AnaGate CAN FZ16C4 provides four Ethernet interfaces with
four electrically isolated CAN FD interfaces for each Ethernet interface. Each Ethernet
interface with its four CAN FD interfaces is referred to as a core unit. Each core unit
has its own independant power supply.
The AnaGate CAN Gateway is controlled and configured via a proprietary protocol
based on TCP/IP. This protocol is described in detail (see [TCP-2010]). Free
application libraries are available for devices with Windows or Linux operating
systems. The entire range of functions of the individual devices can be integrated
into application programs with these libraries.
In the bridge mode, the AnaGate CAN Gateway can connect two physically
independent CAN networks via LAN/Ethernet (LAN bridge mode). This coupling
allows the connection of separate CAN buses with different baud rates.
Note
The AnaGate CAN duo, AnaGate CAN quattro, AnaGate CAN X2, AnaGate
CAN X4, AnaGate CAN X8, AnaGate CAN FX2, AnaGate CAN FX4, AnaGate
CAN FX8, AnaGate CAN F2, AnaGate CAN F4, AnaGate CAN F8, AnaGate
CAN FZ8, AnaGate CAN FZ16 and AnaGate CAN FZ16C4(within a core
unit) can also connect two internal CAN interfaces. The AnaGate CAN uno
does not support this internal bridge mode.
Important
It is also possible to bridge a CAN FD network to a CAN network. However,
it is important to note that CAN telegram data sent from CAN FD networks
to CAN networks may be lost, since standard CAN supports only telegrams
with a maximum of 8 data bytes.
1.1. Features
• The AnaGate CAN FZ16C4 can send and receive CAN/CAN FD messages via sixteen
independent CAN FD interfaces. The device can be controlled with a socket-
compatible device (e.g. a PC or PLC).
• The AnaGate CAN FZ16C4 consists of four core units, which are functionally
equivalent to a AnaGate CAN F4. Each core unit has an Ethernet interface with its
four CAN FD interfaces.
• Each CAN FD interface can be operated individually with CAN 2.0 baud rates 20,
50, 62.5, 100, 125, 250, 500, 800 or 1000kbit/s and with CAN FD data baud rates
0.5, 1, 2, 4, 5 or 8Mbit/s. User defined baud rates are also possible.
• Each CAN FD interface has a software switchable bus termination.

Description

• Two different plugs for power supply. Each core unit has its own independant power
supply.
• The Power over Ethernet variant can alternatively be supplied via PoE/PoE+.
• Communication via a proprietary network protocol.
• Static or dynamic (DHCP) assignment of the IP address.
• Four analog inputs and four analog outputs are available for each core unit, which
can be accessed via Ethernet.
• Several simultaneous network connections (5x TCP and 1x UPD) are supported to
each CAN FD interface.
• Coupling of two independent CAN networks via LAN bridge with two separate
AnaGate CAN Gateways. All devices of the AnaGate product line, except for the
AnaGate CAN USB, support this feature. CAN FD is only supported by the AnaGate
CAN F-series.
• The internal bridge mode allows each CAN FD interface to be logically connected
to one of the other CAN FD interfaces within one core unit.

Figure 1.2. Rear view AnaGate CAN FZ16C4
The rear panel of the AnaGate CAN FZ16C4 features the following connectors and
LEDs for each core unit (from left to right):
Analog IO The AnaGate CAN Gateway has 4 analog inputs and 4
analog outputs1. The IOs are not electrically isolated from the
device and are supplied by the external power supply (see
Section 2.10, “Analog IO”).
LAN Via the RJ45 socket the AnaGate CAN Gateway is connected
with the Ethernet. The device can be connected to a network
component like a hub or a switch. For a direct connection to a
PC, a crossover network cable has to be used. Devices with the
optional PoE/PoE+ feature can use this socket for the power
supply, if they are connected to a PoE/PoE+ capable network
component.
USB OTG (top),
USB Host (bottom)
Two USB 2.0 interfaces(1x OTG, 1x Host) are available for
future extensions or customer specific solutions.
Power supply Besides the optional PoE/PoE+, there are two options for the
power supply.
The device can be connected to an external power supply unit
(e.g. in a control cabinet) via the two-pole pin strip.
When used as a desktop device, the barrel connector (2.1mm /
5.5mm) should be used to connect the device to a plug-in
power supply unit.
The integrated resettable fuse resets at 1250mA (25°C)
(see Section 2.1, “Initial installation”). If high ambient
temperatures are expected, a sufficiently high VSupply must be
provided. The power consumption is about 5W (without USB
or I/O devices).
Warning
Make sure to use only one power supply.
The 'Act'ive LED lights up constantly green, when the power
supply is stable. During an IP output or a factory reset, the
LED flashes yellow (see Section 2.11, “Factory reset”).

Chapter 2. Configuration
2.1. Initial installation
First, the AnaGate CAN Gateway must be supplied with a voltage between 9V and
24V.
Important
The AnaGate CAN F series products have a resettable fuse installed, which
resets at 1250mA (25°C). If high ambient temperatures are expected, a
sufficiently high VSupply must be provided, since the fuse triggers earlier
at higher temperatures. A supply voltage of 24V is recommended in such
cases.
Insert a LAN cable into the plug labeled LAN and connect it either to a hub or switch.
If connecting directly to a PC, use a crossover LAN cable instead.
2.1.1. Factory settings
The AnaGate CAN Gateway has the following initial settings:
IP address 192.168.1.254
Address type static
Network mask 255.255.255.0
Gateway 192.168.1.1
Web login password password
The device can now be configured with a browser (Firefox, Chrome, etc.) by going
to http://192.168.1.254 .
The web interface is protected with a password (factory setting: "password"), which
should be changed on the "Save/Reset Settings" page (see Section 2.6, “Save/Reset
settings”). The local access can be locked again by clicking the menu item "Logout"
or by closing the browser completely.

Configuration

Note
The PC used for the configuration must be in the 192.168.1.x network.
For example, the static IP address 192.168.1.2 with the subnet mask
255.255.255.0 can be used. If necessary, the settings of the network
interface on the connected PC have to be changed temporarily.
2.2. Network settings
On the page IP Settings the following settings can be changed:

Configuration
8 © 2007-2022 Analytica GmbH
Figure 2.2. Web interface, Network settings
DHCP Here you can switch between static IP and dynamic (DHCP)
addresses. If DHCP is being used, the remaining fields are ignored,
because their values are retrieved from the DHCP server. In this
case, a DHCP server must be available and accessible on the
network.
IP address The IP address of the AnaGate CAN Gateway is entered in dot format
(e.g. 192.168.1.200).
Subnet mask The subnet mask is entered in dot format (e.g. 255.255.255.0).
Gateway The default gateway is entered in dot format (e.g. 192.168.1.1).
Leave blank or enter 0.0.0.0, if a default gateway is not required.
Name server The IP address of a name server, which resolves domain names (in
dot format). If a name server is set, the end point of an IP bridge
can be entered as a domain name (see Section 2.4, “CAN settings”).
Local domain Most queries for names within this domain can use short names
relative to the local domain in the end point field of a CAN/IP bridge.
The domain part begins after the first '.'. For example, if xyz.local
is the local domain name, the short name dest is extended to
dest.xyz.local.
The inputs are applied immediately after clicking the button Save all changes and
saved permanently to the AnaGate CAN Gateway. A restart of the device is not
necessary.
Note
After changing the IP address, it may be necessary to clear the ARP cache
of the PC to access the device.

Configuration

2.3. WLAN settings
Devices of the AnaGate CAN F series can use a WLAN ("Wireless Local Area Network")
connection in addition to or instead of a wired Ethernet connection.
Note
Using WLAN on the AnaGate CAN Gateway requires a compatible WLAN-
USB adapter. The WLAN settings are only displayed, if a compatible
adapter has been detected. The adapter should be plugged in, before the
AnaGate CAN Gateway is powered up. The following adapters are currently
supported:
• TP-Link TL-WN721N
• TP-Link TL-WN721NC
• TP-Link TL-WN722N
• TP-Link TL-WN722NC
If a compatible WLAN adapter was detected, the following settings can be changed
on the page WLAN Settings:
Figure 2.3. Web interface, WLAN settings
WLAN enabled Here you can enable the wireless local area network.
SSID The network name ("Service Set Identifier") can contain up to
32 ASCII characters or 34 to 64 hexadecimal characters.
Operation mode This option allows the selection of the WLAN operation mode.
When using the infrastructure mode, a connection to a central
wireless access point is established. The wireless access point
serves as a bridge or router to other networks.

Configuration
10 © 2007-2022 Analytica GmbH
When using the ad-hoc mode, there is no central access point.
Instead, all connected devices communicate directly with each
other. Just like in infrastructure mode, all devices need to use
the same SSID and encryption settings.
Channel This option is only relevant in ad-hoc mode. It controls which
channel and frequency range should be used. In infrastructure
mode, the channel is selected by the central wireless access point
instead.
Encryption mode WPA ("Wi-Fi Protected Access") encryption offers the best
security, but is only available in infrastructure mode. WEP
encryption ("Wired Equivalent Privacy") is considered insecure
and should only be enabled, if WPA cannot be used. WEP only
offers slightly more protection than no encryption.
WPA mode If WPA encryption is enabled, this option allows the selection of
WPA, its successor WPA2 or both.
Cipher mode If WPA encryption is enabled, this option allows the selection
of the cipher mode. The encryption mode TKIP is deprecated.
However, some older devices do not support the encryption
algorithm AES.
Pre-shared key If WPA encryption is enabled, the network key can have a length
of 8 to 63 ASCII or exactly 64 hexadecimal characters.
If WEP encryption is enabled, the network key must have a
length of exactly 13 ASCII or 26 hexadecimal characters.
DHCP Here you can switch between a static IP and dynamic allocation
via DHCP.
IP address Here you can enter the WLAN IP address of the AnaGate CAN
Gateway, if DHCP is disabled.
Subnet mask Here you can enter the WLAN subnet mask of the AnaGate CAN
Gateway, if DHCP is disabled.
Gateway Here you can enter the WLAN default gateway of the AnaGate
CAN Gateway, if DHCP is disabled.
Note
If a gateway is configured for the WLAN interface, a gateway that was
configured for the wired Ethernet interface will be disabled automatically.
The inputs are applied immediately after clicking the button Save all changes and
saved permanently to the AnaGate CAN Gateway. A restart of the device is not
necessary.
Note
After changing the IP address, it may be necessary to clear the ARP cache
of the PC to access the device.
