9) LPT_GPIO (LPT/GPIO Header)
Use this header to connect a LPT or GPIO device. Refer to the descriptions of the LPT_SEL, GPIO_PWRSEL,
and GPIO_SET jumpers for further configuration.

GPIO:
11) GPIO_PWRSEL (GPIO Power Selection Jumper)
Move the jumper cap from the LPT_SEL jumper to this jumper to configure the LPT_GPIO header to support
GPIO device and also to specify the GPIO voltage.
1-2 Close: Set GPIO voltage to +12V.
2-3 Close: Set GPIO voltage to 5V.

10) LPT_SEL (LPT Configuration Jumper)
Place the jumper cap on the two pins to configure the LPT_GPIO header to support LPT device. Note: If
the jumper cap is removed from this jumper, be sure to place it on the GPIO_PWRSEL pins.
Short: Configure the LPT_GPIO header to support LPT device. (Default)
