4-channel digital video capture boards

LDVR-3U configurations using 4-channel digital video capture boards do not

support 25-pin connectors. Instead, these configurations use 4DV-4UP-30F

digital video capture boards, which require BNC connectors. To use the active

video splitter, an expansion board (breakout box) is also required.

Install the Active Video Splitter

8-channel digital video capture boards

1. There are two 25-pin connector ports in the back of the active video splitter.

To install this device, connect the 25-pin connector from port 1 on the back

of the active video splitter to PCI Slot A on the back on the LDVR-3U. This

active video splitter now controls camera inputs 1-8.

2. Connect cameras 1-8 to the active video splitter by plugging the coaxial

cables into the “IN” ports on the front of the splitter.

3. If you are using a CCTV Switcher or an analog monitor, connect a coaxial

cable to the “OUT” port for the channel and connect the other end of the

cable to the CCTV Switcher or analog monitor.

Notes: To connect cameras 9-32 you can connect a total of four active video

splitters to per LDVR-3U.

The signal must be maintained at a one-volt peak-to-peak rating +/- 10% and

the vertical sync at 0.3.
