This is odd, because the data sheet for the sensor itself says that the signal should be the expected [0V,5V]. I can build a translating circuit, but I should not have to, though finding transistors that can switch at ~8.1MHz may be (ahem) interesting. Any ideas?

We spent a few hours trying to understand these signals with the US digital encoder with no luck.
We promptly switched to Grayhill 61R and another encoder module with latex tubing. We are not going to use the US digital modules.
