DPS 8-Bit MicroSYNC Connectors
FIGURE 4-5: DPS MicroSYNC I/0 Connectors
SERIAL DATA INPUT (RJ-14)
This connector is not used when the MicroSYNC is installed in an ES-2200 Expansion System.
NTSC VIDEO INPUT
NTSC video can be connected to the MicroSYNC card in two ways: through the BNC connector as shown in Figure 4-
5 or from the card edge connector as shown in Figure 4-6. The two position jumper CHE2 is used to select the video
input to the MicroSYNC card. Jumper CHE2 is labeled BNC and BUS and is factory set to BNC. The BUS video input
can only be used when both a MicroSYNC and a DPS RS-2800 Personal Video Routing Switcher are installed in an
ES-2000 expansion chassis.
The input to the MicroSYNC card should be 1 V p-p NTSC video signal. It is terminated with 75O at the card. This
signal may be direct color or monochrome. The MicroSYNC cannot be used directly with non-timebase corrected
heterodyne VCRs such as U-Matic and VHS recorders, since it is not a TBC. Typical input sources include satellite,
network, mobile and other remote video feeds. This MicroSYNCs video input is automatically looped to the output
BNC whenever power is off or BYPASS mode is selected.
NTSC VIDEO OUTPUT
This connector, as shown in Figure2-5, supplies a nominal 1 V p-p, 75O composite NTSC output. The video output
contains a synchronized version of the video input signal except when the MicroSYNC is in Bypass or Black mode.
