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.
