LED

Channel Status Indicators: D1 ~ D4

The LED D1, D2, D3, and D4 can be used for indicating the channel status.

LED Signal

D1 Status for Channel-1, the driving signal is connected to

the Channel-1 capturing chipset SAA713xHL’s GPIO15.

A logic low turns the LED on, and a high turns it off

D2 Status for Channel-2, the driving signal is connected to

the Channel-2 capturing chipset SAA713xHL’s GPIO15.

A logic low turns the LED on, and a high turns it off

D3 Status for Channel-3, the driving signal is connected to

the Channel-3 capturing chipset SAA713xHL’s GPIO15.

A logic low turns the LED on, and a high turns it off

D4 Status for Channel-4, the driving signal is connected to

the Channel-4 capturing chipset SAA713xHL’s GPIO15.

A logic low turns the LED on, and a high turns it off

GPIO Status Indicators: D5 ~ D8:

The LED D5, D6, D7, & D8 are used for indicating the status of the digital input/output

signals (pins), labeled as GPIO1 ~ GPIO4 on the board, and directly connected to the

J3. A logic 0 (low) turns the LED on and a logic 1 (high) turns it off.

LED Signal

D5 Status of GPIO1 (associated with Channel-1)

D6 Status of GPIO2 (associated with Channel-2)

D7 Status of GPIO3 (associated with Channel-3)

D8 Status of GPIO4 (associated with Channel-4)

Power-OK indicators: D11 ~ D15

The LED D11, D12, D13, D14, and D15 are used for indicating on-board Power-OK

status.

LED Signal

D15 3.3V Power-OK Status

D14 1.8V Power-OK Status

D13 1.5V Power-OK Status

D12 Power-OK Status for 1

PLX PEX8112 (PCI-Express to PCI Bridge)

D11 Power-OK Status for 2

PLX PEX8112 (PCI-Express to PCI Bridge)

1 2 ... 10 11 12 13 14 15 16 17
