WAGO connector for CAN interface

The Avisaro 2x CAN Box comes with two CAN ports connected using a WAGO connector. The first port (Port 1) is the primary one (able to receive commands). The second port (Port 2) is the auxiliary one.

WAGO Connector

1) Signal Ground (GND)

2) CAN-L

3) CAN-H

4) Single Wire CAN

5) Supply voltage (6 - 32 V)

6) Supply and Signal Ground (GND)

CAN D-Sub to WAGO adapter

Using the Avisaro D-Sub to WAGO adapter, one can connect a standard CAN cable to the Avisaro Box.

Standard SubD-9 connector (male)

1) VCC

2) CAN-L (Dominant Low)

3) GND

4) not connected

5) not connected

6) GND

7) CAN-H (Dominant High) / Single Wire CAN

8) not connected

9) VCC

The SubD connector is realised using a WAGO to SubD adapter. This adapter is usually shipped with the box - check 'scrope of delivery'. Details on the adapter can be found here.

The barrel connector on the WAGO-SubD adapter is layouted as follows. Supply voltage is 6 - 32 V. '
Diameter of the connector is 2.1mm.

DIP switch

The Dual CAN Datalogger can be configured using a DIP switch. This switch is located inside the box at the bottom side of the PCB. When opening the box, make sure power supply is unplugged.

If the logger is equipped with WLAN, the DIP switch is covered by the Avisaro Base board. Use a screwdriver to lever the base board of its socket. Do not bend the connector stripes.

The assignment of the DIP switch is:

1) Terminating resistor CAN port 1 (^*1)

2) Terminating resistor CAN port 2 (^*1). Load resistor when implemented as single wire can (^*2).

3) Power enable on wakeup for port 1. Currently not used. Should be OFF

4) Reference voltage input. ON = MC33897 transceiver, OFF = SN65HVD transceiver

5) not used

6) not used

7) not used

8) not used

^(*1): ON = resistor is active, OFF = resistor is not active

^(*2): Should be ON when used in single wire
