dSPACE DS1103, Hardware Installation And Configuration Manual

Page: 241 / 302

The DS821 contains the following element:
n
Status LEDs display the current status of the connection. These
LEDs can be used for troubleshooting purposes:
n
A lit yellow LED indicates that the connection between the host
PC and a dSPACE box (or DS830) is ready for communication.
n
A lit green LED indicates that data is being sent or received.
n
Patch cable connector is an RJ45 connector. It is used for the link
via crossed
‑
over patch cable to the DS814 Link Board (Box), DS830
or MicroAutoBox.
