Connectors and LEDs

The status LED (labeled RUN/PAUSE) indicates the state of the target as follows:

• The LED is green when the target is in run mode.
• The LED is red when the target is in pause mode.
• The LED is orange when the target is in mixed mode.
• The LED is initially unlit and remains so until the debugger is connected to the Ethernet TAP probe.

For the definition of run and pause modes, see Run/Pause/Mixed mode states topic.

The target power LED (labeled TGT/PWR) indicates whether the Ethernet TAP probe detects target power.

• The LED is green when target power is detected.
• The LED is unlit when no target power is detected, or if the debugger has not connected to the Ethernet TAP probe.

The Heartbeat LED (labeled HEARTBEAT) indicates the status of communications between the Ethernet TAP probe and the network as follows:

• The LED is red until the Ethernet TAP probe boot code starts running.
• The LED flashes orange during configuration of the network interface.
• The LED flashes green after network interface has been successfully configured.
• The LED is unlit if the Ethernet TAP probe is not powered on.

Not used.

The external power connector is located on the back of the Ethernet TAP probe. The Ethernet TAP probe cannot operate without external power.

The Ethernet TAP probe interface consists of an RJ-45 connector and a built-in twisted pair MAU that connects directly to 10/100BaseT twisted pair networks. Adapters are also available to connect to networks that use thinwire (10Base2) and thickwire (10Base5) cables. See Connecting to network or Setting up standalone PC Ethernet topic for more information on connecting to an network.

The Ethernet TAP probe RX and TX indicators are integrated into the RJ-45 Ethernet TAP probe connector. The RX indicator is green and flashes when data is being received from the network. The TX indicator is yellow and flashes when the Ethernet TAP probe is transmitting data to the network.

The Config Serial communications port on the Ethernet TAP probe supports RS-232 communications protocol at 9600 baud. The serial port uses an RJ-11 six-conductor phone jack. The Config Serial port is used for configuring network communications, entering routing tables, and for diagnostics.

Pin 1 is on the right side as you look at the RJ-11 socket (locking tab on the bottom.)

The Ethernet TAP probe provides a target serial port which can be configured to access your target's serial port. This is particularly useful if your host computer is not near your target and you need to access your target's serial port remotely over your network. For pinout definition, see Pinout definition of the config serial port topic.

The probe tip cable is connected to the 50-pin D-style connector on the Ethernet TAP probe.

The debug port socket is on the end of the probe tip and is used to connect the Ethernet TAP probe to a debug port header on your target system.
