FAQ |
| 8/27/2008 | What are the functionalities of orange/black, yellow/black, and blue/black cables? + Show Answer Orange/black cable is total PFD signal (TTL signal, Power Failure Detection). It indicates total power condition.
Yellow/black cable is PW1 (power module 1) PFD signal (TTL), normal High and failure Low.
Blue/black cable is PW2 (power module 2) PFD signal (TTL), normal High and failure Low. |
