1.10.2 Output Supply Volta ge
The regulated output voltage is available at socket X302 (
û
).
Figure 12 shows the socket’s pin-out.
Figure 12: Connecting the Supply Voltage Output X302
Connect the output X302 with the supply voltage input of the
CPU-card you inserted. It is important to note the pin-out of the
CPU-card.
Note:
•
The output voltage is not directly connected to the PC/104-Bus
pins. Since CPU-cards tend to require greater current, the supply
for the PC/104-System is fed over the CPU-card and from there
distributed over the bus.
•
The Framegrabber is not fed directly by the supply voltage, rather
over the bus connector of the PC/104-System.
•
It is also possible to connect peripheral devices (floppy disc drives,
hard drives etc.) to socket X302. For hard drives and similar
components it is important to be careful that the beginning start-up
current during a power up does not exceed the maximum allowed
output current. In this case the supplies surge protector takes effect
and the components won’t start correctly.
•
The presence of the operating voltage is shown by the LEDs D307
/ D308 next to the socket X302. If an LED does not illuminate, or
illuminates only slightly, then it is possible that the integrated
surge protector on the adapter was activated. When the current load
is reduced the supply will once again deliver the correct output
voltage.
