CP3010-SA
Note:
The pins for the interfaces COMA and COMB (pins A18, A17, A16, B18, B17, B16, B10, B7,
C18, C14, C13, C11, D18, D10, E18, and E16) tolerate only 3.3V signaling and their inputs
(driven by the rear I/O module) have internal pull-up resistors.
General Purpose Inputs/Outputs
Alternatively, the following GPIO signals are available instead of the COMB signals if pin D4 on the rear
I/O connector J2 (GPIO_CFG0) is set to 0.
Note:
The pins for the GPIO interface (pins B17, B10, B7, C14, C13, C11, D18, and D10) tolerate
only 3.3 V signaling and their inputs (driven by the rear I/O module) have internal pull-up
resistors.
VGA Interface
VGA signals are available either on the front VGA connector, J6, or on the rear I/O interface due to the
implemented switch on the CP3010-SA. Switching over from front to rear I/O or vice versa is effected
using the uEFI BIOS.
Note:
On the rear I/O, the CP3010-SA provides 150
termination resistors for the red, green
and blue VGA signals. Thus, further 150
termination resistors are necessary on the rear
I/O module to reach the required 75
termination for the VGA connection.
