Overview
1. Overview
This document describes the hardware of the following CAN-USB/400-Modules:
- CAN-USB/400
- CAN-USB/400- R G-B
- CAN-USB/400-FD
The CAN-USB modules have an identical structure, except of the additional R G-B and /O
interfaces at the CAN-USB/400- R G-B and the CAN FD interfaces at the CAN-USB/400-FD.
f identical features or procedures are described in this manual, the term CAN-USB/400-Module is
used for the three modules. Differences are noted explicitly.
1.1 CAN-USB/400
Figure 1: Block circuit diagram of CAN-USB/400
The basic version CAN-USB/400 offers two high-speed CAN interfaces, according to SO 11898-2,
for USB. The CAN interfaces are electrically isolated and support bit rates up to 1 Mbit/s.
The independent CAN nets, according to SO 11898-1, are driven by the SO 16845:2004 certified
esdACC (esd Advanced CAN Core), implemented in the Altera® FPGA .
Attached to USB via F FO's and driven by the esdACC, the CAN-USB/400 is designed for
minimum latency CAN communication via USB.
Advanced diagnostics and high resolution hardware timestamping are supported.
A feature pretty unique on standard CAN interfaces is the Error njection. t provides means to
simulate error conditions on CAN bus. Bit patterns can be injected into any living CAN bus. Several
trigger conditions and modes are provided.
Power is supplied via USB.

Overview
1.2 CAN-USB/400-IRIG-B
Figure 2: Block circuit diagram of CAN-USB/400- R G-B
n addition to the standard features of the CAN-USB/400, the CAN-USB/400- R G-B offers analog
and digital R G-B inputs, synchronized timestamps (even without R G-B signal) over several
CAN-USB/400- R G-B via additional RS-485 interface, external trigger /Os for Error njection and
miscellaneous /Os for customized functionality.
1.3 CAN-USB/400-FD
Figure 3: Block circuit diagram of CAN-USB/400- R G-B
The CAN-USB/400-FD comes with two independent CAN FD interfaces according to SO 11898-
1:2015, instead of the Classical CAN interfaces of the CAN-USB/400.
The CAN FD interfaces are driven by the SO 16845:2004 certified esdACC (esd advanced CAN
Core) implemented in an Altera® FPGA. The interfaces are able to send and receive SO conform
CAN FD (up to 5 Mbit) or CAN 2.0 A/B messages. The CAN FD bit rate range is validated for the
esdACC CAN FD core from 10 kbit/s up to 5 Mbit/s.
The CAN-USB/400-FD can also be used in Classical CAN Applications, because CAN FD is fully
backwards-compatible with CAN.
As customized option, the analog and digital R G-B inputs are available on request
Customized options are available for customized series production in reasonable quantities.
