6. Using the Debug Adapter (ISA3)
6.1 Overview
The Debug Adapter (ISA3) provides an Ethernet connection to EM35x devices. You can use the Debug Adapter (ISA3) to perform the
following tasks:
• Program and debug using Serial Wire or JTAG.
• Monitor packets sent and received by the radio.
• Send and receive serial port data.
• Send and receive debugging data.
• Turn power on and off.
• Control reset, bootloader and GPIO signals.
6.2 Connectivity and Power
All the features of the Debug Adapter (ISA3) are available via the Ethernet connection. The Debug Adapter (ISA3) can also be connec-
ted to a PC via USB to change the Ethernet settings.
When connected via USB, the Debug Adapter (ISA3) will also be powered via USB. It should be connected to a powered USB hub, or
port on your PC that is capable of supplying full power to connected devices.
When connected via Ethernet, the Debug Adapter (ISA3) may be powered in one of two ways:
1. Using an Ethernet switch that supplies Power Over Ethernet (PoE).
2. Using a USB power supply.
The Debug Adapter (ISA3) will also supply power to the connected EM35x device when the power switch is in the INT (Internal) posi-
tion. If the connected EM35x device has its own power supply, ensure the power switch is kept in the EXT (External) position.
You can connect via Ethernet to the ports listed in the following table using either the Silicon Labs development environment or a termi-
nal application (for example, Microsoft Telnet Client, HyperTerminal, or PuTTY).
