hard coded, the API re-programs the video source register (0x02) after loading the

ENC*.INI file.

NOTE: Since the 2246 API uses the xx.INI files for programming the 2246, changes

made to DEC_NC.INI and ENC_NC.INI must be restored before running the

application (calling the API).

2246 Power On Sequence

The 2246 contains on board LED’s that indicate power and status.

LED’s D11, D12, D15, D17, and D18 indicate the presence of board voltages 5v,

3.3v, 1.2v, 2.5v, and 1.8v respectively.

After Power on, LED D16 will light up indicating that all power lines are OK.

Following power on, the 2246’s USB controller will start looking for a connection

to the host computer. LED’s D1, D2, D3, D4, D5, D19, D20 on the 2246 indicate

the status of the USB and the status of the Host computer’s Windows driver’s.

Table-1 describes the LED sequence seen when Windows loads the 2246 USB

drivers.
