7.1 LED

There are two LEDs available, with D201 indicating power status of DSK and D202 indicating the

module status.

D201 is a green LED that is controlled by the supply from either the DC Adaptor or USB supply.

D202 is lit when TR-900 is powered up.

7.2 Switches

7.2.1 Power ON Once power is supplied to the DSK through an external source, the PWON will provide “Vbatt” to TR-

900 when pressed for at least 35ms (i.e. “ON”)

After a 3 seconds press, TR-900 will be switched off.

7.2.2 Reset The reset button will start a hardware reset on TR-900 when pressed.

Please note that Reset is applicable only when TR-900 is “ON”.
