I'm not sure because of the list delays if you saw my reply to your ticket from a few days back.
In relation to the power: There are three power buses on this product, each can handle any voltage from -60 to +60 or thereabouts. The only condition is that they all have to be able to share a common return. Each card in the rackinjector has different rules about how they pull from the busses. Currently the logic power supply in the rackinjector/control board needs at least one of the busses to be positive in respect to return. But the other two busses can be positive or negative or not connected. We're working on removing the positive ppwer requirement in a future hardware revision. Separate from the logic power supply is the power which is supplied to the radios. Each port on each card can be individually set to a given power bus. This isn't per card, it's per port. Whether a given port is able to use a given polarity depends on the card and the radio. The powerinjector plus sync card only supports providing positive voltages to the radios. The other two types can support either polarity assuming the radio can also use that polarity.
