Connector
Connector front
The CANmod.gps uses a DB9 (D-sub9) connector for supply and CAN-bus (CAN-P). It uses a mini-USB connector for configuration, streaming, 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
Warning
The Supply (5 V) pin tolerates 5 V only
Note
The CANmod.gps can be directly powered from the CANedge 2nd port 5 V output.
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. For more information see USB.
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.
