Connecting the Reference Genlock
The Profile Video File Server provides a Reference Genlock board, standard on all
configurations, with two BNC connectors and a 25-pin DIN connector. The BNC
connectors form a bridging, high impedance loop-through for the analog black burst
house reference signal. This signal is used to synchronize the system video clock and
provide frame reference. The 25-pin DIN provides Longitudinal Time Code
interfaces, four in and four out. See Figure 2-8.
Figure 2-8. Reference Genlock Cable Connections
To make cable connections to the Reference Genlock board, refer to Figure 2-8 and:
1. Attach the optional Longitudinal Time Code breakout cable (Figure 2-9) to the
25-pin DIN connector.

2. Place EMI gaskets on the BNC connectors as shown in Figure 2-6, page 2-7.
3. Attach the House Reference (Black Burst) BNC cable to the lower BNC connector.
4. Attach a 75
Ω
End-line Terminator to the upper BNC connector.
