Table 1: XMC-A825-16 Front Panel Elements
The CAN activity LEDs located on the front panel (TX, RX) indicate if a CAN channel transmits and/or receives
CAN messages. Every CAN channels has a dedicated RX/TX activity LED which flashes once for every
transmitted/received message or continuously at a rate of 2Hz in case of a steady message flow.
If the RX activity LED of a particular CAN channel stays dark in an active network, the physical interface
correctness of all network nodes including the used baud rates, sample points and termination resistors should
be verified.

Description
ETHERNET Connector
Standard RJ-45 connector used for the interface between XMC-
A825-16 and other computer systems using 10/100/1000 BaseT
Ethernet. The XMC-A825-16 Ethernet supports auto-negotiating of
the bus speed as well as support for ICMP echo requests so that
XMC-A825-16 systems respond to “ping” commands over the
network.
This connector is only used when the on-board Intel Gigabit
Ethernet Controller is not enabled. To use this interface, the option
PCI=0 must be set in the configuration file “XMC_A825.CFG” on the
micro SD card installed. See the Section entitled XMC-A825-16
Configuration
Status LED S1
Bicolor LED which is illuminated in red during the start of the XMC-
A825-16 firmware or in case of an internal system failure. This LED
flashes green during normal operation (with 90% on-time versus 10%
off-time).
Status LED S2
Bicolor LED which is illuminated in red during the start of the XMC-
A825-16 firmware or in case of an internal system failure. This LED
flashes green during normal operation (with 90% on-time versus 10%
off-time).
