Table 162: Pinouts for UIC to Receiver Communications Connector (J102)
1
A filter module (similar to Delta FL 75L07) in series with the power cable maybe needed to pass conducted emission.
2
A tubular ferrite bead (similar to Laird Technologies 28B0375-300) maybe attached to the data cable to reduce radiated
emissions.
3All signal I/O are at LVCMOS levels (not 5V tolerant).
