USB2ANY Interface Adapter

Figure 3. USB2ANY PCB

The Status LED indicates the status of the electronics and firmware, as follows:

Table 1. Status LEDs

LED State

Meaning

OFF

No power to the board. USB cable may be unplugged.

ON

Power is applied and the board is operating normally.

Blinking

A hardware, firmware, or USB error occurred. Board must be power-cycled.

NOTE:

The LED may also be programmed using the software API to be ON, OFF, or blinking. In

that case, the LED may not indicate the actual status of the electronics or firmware.

Switch S1 is used to put the firmware into bootstrap loader (BSL) mode. The BSL mode is used to load or

update the USB2ANY firmware and is entered whenever the board is powered-up while Switch S1 is

depressed.

The USB Mini-B (J2) connector is used to connect the USB2ANY to the host computer. A cable with a

USB Mini-B connector on one end and a USB A connector on the other end is provided with the

USB2ANY.

The JTAG connector (J1) is used only for firmware development and is normally not populated with a

physical connector.
