Connecting the Device

For connecting the device with a PC, see the CANlink wireless 4000 User Guide.

Warning

Overload damage due to malfunction.
Risk of severe or fatal injury.

To limit power in the event of malfunction, secure the DC power supply circuit during installation with an external 1A fuse.

Note

Risk of property damage.

  • The device must be installed, connected, and commissioned by a qualified technician.
  • Ensure the power supply is disconnected before connecting the device.
  • Only use components from the starter kit or the available accessories.
    Refer to chapters Launch Kit and Software and Accessories.

If you have any questions or anything is unclear, please contact our support before getting started. See chapter Service and Support.

Connecting an external antenna

The Type 4003 features an FAKRA antenna connector for connection of the RF antenna Bluetooth/Wi-Fi® antenna (part number 157000126).

Tip

You can request more information about other permitted RF antennas using the Proemion support form at Support.

Danger

Danger of explosion due to the operation of electrical equipment in potentially explosive atmospheres.
Severe injury or death.
- Observe the applicable regulations and precautions for potentially explosive areas. - Do not mount the antenna in the close proximity of easily ignited substances (e.g. fuel tanks) and insufficiently shielded electronic devices.

Warning

Health hazards of radio-frequency energy
Slight or medium injury.
- Make sure the device is switched off during installation.

Note

Property damage
The device or antenna can be damaged.
- Do not shorten or lengthen antenna cables.

Note

Reduced antenna gain
Problems with the wireless connectivity can be caused by an insufficient antenna setup.

  • Only use the antennas which are supplied as Proemion accessories.
  • Change the mounting position of the CANlink® wireless 4000 to reduce the distance between antenna and the device.
  • Do not extend the antenna cable. Order an alternative antenna with longer antenna cable.
  • Keep the length of the antenna cable as short as possible.
  • In case of using the antennas which are supplied with the hardware kit or as Proemion accessories: Ensure that the minimum bending radius of the antenna cables is 8 times the outer diameter.

Note

Loss of FCC certification possible.

  • Only use antennas which are approved for the frequency range used.
  • Only use antennas which do not cancel the Wi-Fi® or the Bluetooth qualification.
  • Keep the end of the antenna away from metal components to avoid detuning.

CAN

Connect the device interfaces to the CAN bus whose data you want to log or send. For test purposes, connect the device to a PC using a communication gateway (e.g. PCAN-USB - CAN/USB Interface).

The CAN connection terminal CAN-High and CAN-Low signals must match the signals of the connector on the device. You can connect Ground of the supply connector with CAN-GND because there is no galvanic isolation.

The following table provides an overview of the CAN bit rates in relation to the bus length:

CAN baudrate Maximum bus length
1 Mbit/s 25 m
800 kbit/s 50 m
500 kbit/s 100 m
250 kbit/s 250 m
125 kbit/s 500 m
50 kbit/s 1000 m

CAN bus termination

In any bus system, signal reflections at the end of a wire or cable can cause interference which can in turn cause transmission errors. To minimize these reflections, place a terminator at each end of transmission lines.
The terminating resistance between CAN-High and CAN-Low must match the characteristic impedance of the transmission cables. In CAN bus networks, normally unshielded, twisted cable pairs are used for signal transmission.
The characteristic impedance of the transmission lines is roughly 120 Ohm.
The terminator between CAN-High and CAN-Low must be 120 Ohm.

Power supply

The device is supplied with power via the CAN connector.

Note

When switching on, terminal 30 must always be connected to the power supply before terminal 15 changes to status high.
Otherwise the device may not initialize correctly.

Note

For tests, firmware and configuration updates in the laboratory setup, the power supply and cables from the launch kit must be used.
