Introduction
1 Introduction
1.1 Overview
Congratulations on your purchase of the IXXAT CANbridge, a high quality elec-
tronic component developed and manufactured according to the latest techno-
logical standards.
The CANbridge is a universal, intelligent CAN topology component based on the
store-modify-forward principle.
The component allows a configurable coupling of two, also different, CAN net-
works. It is configured via a configuration file and the download program in-
cluded in the delivery.
This manual is intended to familiarize you with your CANbridge. Please read this
manual before beginning with the installation.
1.2 Features
• Supply voltage 9-36 V DC (automotive version 7-16 V DC)
• CAN bus interface according to ISO 11898-2, as an option galvanically iso-
lated
• Optional CAN low speed bus interface according to ISO 11898-3 (“fault-
tolerant”) for automotive version
• Serial interface (RS232) for configuration of the CANbridge (as an option
RS485)
• Fujitsu 16-bit microcontroller
• Two housing designs available: robust aluminum housing or plastic housing
for DIN rail assembly

2.1.1 Voltage supply (X1)
The device is supplied with direct voltage of 9 V - 36 V. With the automotive ver-
sion the supply voltage is 7 V - 16 V. A pre-fabricated cable for power supply is
included in the scope of delivery. The connection allocation is shown in Table 2-1.
The CANbridge is protected against polarity reversal, under-voltage and over-
voltage. In the event of polarity reversal or under-voltage, it is switched off, with
over-voltage an internal fuse is triggered.

2.2 Ground connections
In the galvanically isolated version, the GND of CAN1 (X3) and CAN2 (X4) is iso-
lated in each case from the rest of the circuit, the GND of the serial interface (X2)
is connected to the GND of the power supply (X1).
In the version without galvanic isolation, all GND connections (X1, X2, X3, X4)
are connected with each other.
The shield connections of CAN1 (X3), CAN2 (X4), serial interface (X2) and power
supply (X1) are connected with each other both in the version with and in the
version without galvanic isolation.
