Figure 20 on page 41 shows the location and pin orientation of the LVDS back light connector.
The next table lists the pinout of the LVDS backlight connector.
Table 13. LVDS Backlight Connector Pinout
Pin Signal Name Function
1 LVDS_BKLT_EN
LVDS backlight enable output. (5V TTL-level signal by default
but will operate at higher voltages if the LVDS_BKLT_PWR is
provided).
High = enabled, Low = disabled.
2 Signal Ground Ground
3 LVDS_BKLT_CTRL
LVDS backlight control output. (5V TTL-level signal by default
but will operate at higher voltages if the LVDS_BKLT_PWR is
provided). This is a PWM signal and the duty cycle can be
set in the BIOS Setup utility.
4 LVDS_BKLT_LOGIC_PWR
Optional backlight logic power input. (Can range from +5V to
+14V and sets the high-value on the LVDS_BKLT_EN and
LVDS_BKLT_CTRL signals.)
On-board +5V power is used when this is not connected.
Cabling
An adapter cable, part number CBR-0404, is available for powering the LVDS backlight from
the Condor board.
If your application requires a custom cable, the following information will be useful:
