Connector J27
Connector J27 is for interfacing with the backplane PXI_CLK10 circuitry.
Figure 9 shows the J27 location, and Figure 10 shows the pin descriptions.
Positronic manufactures the J27 mating connector, which you can order
with part number CBD7W2M2000Z-759.1.
Figure 10.
J27 Connector
Connector J26
Use connector J26 in conjunction with J29 for interfacing with an inhibit
switch and LED. You do not need to connect anything to J26 for basic
backplane power up. The power button (PWRBTN#) signal is a momentary
pushbutton signal that tells the system controller to enable or inhibit the
power supply. You can use signals LED1 and LED2 to drive a bicolor LED
in the power switch, but you also can use these signals to carry another
digital signal.
Figure 8 shows the J26 connector location. Refer to Table 3 for the pin
descriptions.
