Connector

Connector front

The CANmod.gps uses a DB9 (D-sub9) connector for supply and CAN-bus. It uses a mini-USB connector for configuration and firmware update.

Supply

The supplies are internally protected against reverse polarity and low-energy voltage spikes. Refer to the Electrical Specification for more details on the device supply.

The device can be powered through the DB9 connector using one of the below supply lines:

  • Supply (5-24 V), pin 9

  • Supply (5 V), pin 1

If the module is used with a CANedge device, it can be directly powered using the Supply (5 V) pin (requires that the 5V output is enabled in the CANedge configuration).

Warning

The Supply (5 V) pin tolerates 5 V only

GND

All GND (ground) pins are connected internally.

CAN L/H

The CAN L/H should be connected to the CAN-bus.

Warning

CAN-bus requires no common reference (ground). However, it is recommended that GND (ground) is carried along with CAN-L/H to prevent that the common-mode voltage is exceeded (resulting in transceiver damage)

USB

The USB can be connected to a PC via a mini-USB cable. This allows access to the device configuration etc. For more information, refer to the USB Section.

Connector back

The GNSS antenna is connected to the SMA connector.

Antenna

The CANmod.gps is tested with the ANN-MS-0 antenna from u-blox (active 50 Ohms antenna with integrated Low-Noise-Amplifier).

Warning

The antenna which is shipped with the CANmod.gps uses a magnet for mounting. Make sure to keep the magnet away from sensitive devices.
