LEDs
There are two sets of LED on the board, green and red. Each LED has a label which Voltage it represents. The green LED,
when lit, indicates presence of the corresponding voltage. The red LED, when lit, represent a short on the corresponding
voltage at the output. Please note that the green LEDs indicate presence of some voltage and do not necessarily indicate if
the exact voltage is at the expected level.
LED Purpose of LED
D10 -12V is present
D11 +12V is present
D12 +5V is present
D13 +3.3V is present
D18 +VIO is present
D9 -12V has a short or low voltage condition
D15 +12V has a short or low voltage condition
D14 +3.3V has a short or low voltage condition
D16 +5V has a short or low voltage condition
5V
ó 3.3 V Translation
PCIBX is capable of allowing 5V UUT to work with 3.3V system and vice versa, without any timing degridation. Therefore
cards or components needing 3.3 V signaling can be tested or operated on a 5-volt system using these extender cards.
+5V cards can operate in +3.3V systems provided that +5V is provided to the UUT cards.
If JP3 is installed the UUT signals will be the same as the bus signals, most likely +5V.
If JP3 is not installed the signals between the bus and the UUT will be translated.
