1 Introduction
The PCAN-Optoadapter is a universal plug-on adapter to allow galvanic isolation of
High-speed CAN bus systems.
Its integrated logic means that decoupling can be installed at any point in the
CANnetwork.
The PCAN-Optoadapter can be used in CAN FD buses with data bit rates up to
2Mbit/s and nominal bit rates up to 1 Mbit/s.
1.1 Properties at a Glance
Plug-on adapter for decoupling a CAN bus for PEAK CAN interfaces
Galvanic isolation by DC/DC converters up to 500 V
Bit rates from 5 kbit/s up to 1 Mbit/s
High-speed CAN transceiver NXP PCA82C251
Suitable for the use in CAN FD buses with data bit rates up to 2 Mbit/s and
nominal bit rates up to 1 Mbit/s
CAN bus connection via D-Sub, 9-pin (in accordance with CiA® 106)
Status LED for supply voltage indication
120-Ohm bus termination at the female D-Sub connector
Power supply (5 V) through pin 1 of the High-speed CAN connection. Nearly all
CAN interfaces by PEAK-System can provide the required supply
Extended operating temperature range from -40 to +85 °C (-40 to +185 °F)

1.2 System Requirements
The power supply is done via pin 1 of the 9-pin female D-Sub connector (primary
side). Therefore the attached CAN interface must provide 5 Volts.
Since the PCAN-Optoadapter already contains a CAN bus termination on the
primary side, the connected CAN adapter doesn’t need to be terminated
separately on this side.

2.1 Connection Primary Side
The PCAN-Optoadapter is connected to the CAN interface on the primary side.
Pin assignment at the primary side (D-Sub female)
The lines for the differential CAN signal CAN_H and CAN_L are terminated on the
adapter with a 120-Ohms resistor (fixed). An additional termination at the
CANinterface is not needed.

2.2 Connection Secondary Side
A High-speed CAN bus (ISO 11898-2) is connected to the 9-pin D-Sub connector. The
pin assignment for CAN corresponds to the specification CiA® 106.

3 Operation
3.1 Operation
A configuration of the PCAN-Optoadapter is not needed. You can use it instantly.
For general supply the adapter uses a direct voltage of +5 V. This must be applied to
pin 1 of the CAN connector. The CAN interfaces of the PCAN series are able to provide
5 Volts on pin 1.
When the 5-Volt supply is active, the LED on the PCAN-Optoadapter is green.
Risk of short circuit! When you connect the PCAN-Optoadapter to or
remove it from a CAN interface, latter must be turned off (without
power supply). Otherwise the PCAN-Optoadapter or other electronic
components may be damaged.

3.2 Signal Delay
The PCAN-Optoadapter has a transit time delay of approx. 80 ns. This corresponds
to a cable length of 16 m. Therefore, you should consider the dependence of the
maximum length of a CAN bus on the bit rate at the installation of the
PCAN-Optoadapter. The following table shows the maximum possible CAN bus length
at different bit rates:
Bit rate Bus length Bus length with Optoadapter
1 Mbit/s 40 m 24 m
500 kbit/s 110 m 94 m
250 kbit/s 240 m 224 m
125 kbit/s 500 m 484 m
50 kbit/s 1.3 km
For small bit rates,
the delay of the adapter
can be neglected
20 kbit/s 3.3 km
10 kbit/s 6.6 km
5 kbit/s 13.0 km
The listed values have been calculated on the basis of an idealized system and can
differ from reality.
3.3 Status LED
The LED on the top of the PCAN-Optoadapter indicates, whether it is correctly
supplied. In this case, the LED is continuously green.
