Using Ethernet
CarDAQ-Plus’s default “Client then Server“ mode is strongly
recommended. No configuration changes are required when moving
the CarDAQ-Plus between LAN and in-vehicle use.
To a Laptop Directly
Connect the direct-connect Ethernet cable (blue with red ends) between
a PC and the CarDAQ-Plus. This is a crossover type, intended to connect
directly to a computer.
To an Existing LAN
Connect a standard Ethernet cable. On most LANs, CarDAQ-Plus can
obtain its IP address automatically using DHCP. Ask your network
administrator if this service is available on your network.
Vehicle Connector
The mating connector is a standard
MVCI, High Density DB-26.
