1. I looked at the document in the knowledgebase and it doesn't make sense. According to the manual there is no (Vcc) connection at all, instead it refers to a ground reference terminal (GND).
2. I agree, the jumpers were the first thing I checked.
3. The manual states that it has current limiting built into the inputs.
4. In this rack I'm using the 1162 in parallel mode cabled directly to a PCI-DIO-32HS card, and yes there are some scxi-1100 cards in multiplexed mode.
5. My signals are terminated on a TBX-1326 block that is cabled to the 1162
6. No, when it stops working, this is permenant. Unless you replace the card.
7. I have looked at that document before, but these aren't flickering.
