5.12.6 Ethernet 100/1000 Base-T Interface
The PIIC Ethernet Data Interface (Figure 5-1e) is a full duplex 100/1000 BaseT supported by an
RJ45 connector . The EDI supports the input of generic UDP packets or Pro–MPEG COP3
formatted packets. With the Pro-MPEG input, a powerful video-specific packet-based forward
error correction (FEC) algorithm is also available providing a cost-effective solution for error
recovery in video streams transported over public or private IP networks.
5.12.7 EIA-530 /RS-422 Serial Interface
The EIA-530 Port is an RS-422 Connection. It is a 25-Pin Female “D” Connector. Refer to
Figure 5-1i and Table 5-10 for pinouts.
