Page 11: Vna Chaining Interconnection
Encoded Video/Audio/Data is sent to the VNA for IP streaming via its Chaining In connections. The encoded Video/Audio/Data can be chained out from a VETA Receiver (Figure 5) or chained in a VETA Transmitter (Figure 4) 100-M0105X1 11 of 23 www.cobham.com/gms ... -

Use individual screened cables (type RG 174 or better) for each signal and connect each screen to the corresponding ground pin as shown in Figure 6 (RX example). The lengths of the cables should be matched and they should not exceed 20cm in length for reliable system operation. Figure 6 VNA Connectors Layout 100-M0105X1 12 of 23 www.cobham.com/gms ... -
