Hello to all.

The old SD connect C4 (SP100-D) will stop production soon.

And you will have SD connect C4 PLUS (SP100-E) instead.

The new sdconnect is released in the year 2019, features the old c4 and DoIP communication.

What is DoIP and what’s good?

What is DoIP?

Short and simple: “DoIP is the packaging of diagnostic messages 
in Ethernet frames for communication of a diagnostic tester with a vehicle”
• DoIP is a standardized diagnostic transport protocol according to 
ISO 13400
• DoIP is used in combination with the standardized diagnostic protocol 
UDS (ISO 14229-5: UDSonIP)
• Services of UDSonIP are identical to UDSonCAN
• DoIP with Ethernet 100 Base-TX instead of CAN enables substantial 
higher bandwidth
• Vehicle access with DoIP is backwards compatible using discretionary 
pins of the existing diagnostic connector
• DoIP enables easy integration into various network structures, 
even with WLAN

What’s good of DoIP?

Performant handling of huge data volumes
Time-saving at ECU Flash Programming
Cost-efficient because no VCI is necessary
Simple integration to IT Infrastructure
Flexible use because of standardized communication
Integrated with other standards for vehicle diagnosis
Future-proof technology enables various use cases
