Configuring the DLC300 Module Operation
Setting the SW4 Mode Select Switch
The SW4 mode select switch (see
Figure 3)
determines the operating mode for your DLC300.

1. Subject to EG-34 dithering as configured by the EG-34 dithering DIP switch (see
“Setting the SW3 Configuration
DIP Switch” section on page 11
).
2. When ATSC-to-ASI conversion is enabled, the monitor output is the ASI version of the signal (see
“Setting the SW3
Configuration DIP Switch” section on page 11
).
Setting the Configuration DIP Switches
The SW1, SW2, and SW3 configuration DIP switches (see
Figure 4
) determine the functionality of the DLC300
as follows:
•
SW1—Controls the video rate and forced bypass function settings.
•
SW2—Controls the input source (BNC IN or backplane connector) for transmitter mode and
operation of the standby video pattern generator.
•
SW3—Controls the following functions: SDI dithering, ATSC to ASI video conversion, SFP alarms,
optical reversion, video loss alarm, and EMS enable setting.
