Since the WINC 900A alternatively transmits and receives when on-line, the TXD and RXD
indicators cycle between green and red at the configured data rate.
When the default reset button is pressed, the WINC 900A either defaults to the factory preset
configuration of 9600 bps, 8 bits per character, no parity, 1 stop bit, hardware flow control, and auto
answer or resets to the previously configured state. To ensure that the device resets to the default
conditions, first power down the unit and then power it on while depressing the reset button.
To the right of the serial line LEDs are two small rectangular LED indicators. The upper red
indicator lights when the power is on, while the lower green LED indicates the receive signal level.
Solid ON indicates sufficient signal strength, while solid OFF indicates either no received signal or a
signal too weak to sustain communications. A blinking signal indicates a marginal signal level.
If you experience difficulty in making connections between a local and remote WINC 900A, first
reset both units to the factory default conditions and retry before calling for technical assistance.
