Configuring the DLC170AD
This section describes how to configure the operation of the DLC170AD. You must configure the module while
it is out of the host chassis because the configuration DIP switches are mounted to the top of the module PCB.
DIP switches SW1, SW2, and SW4, slide switch SW5, and rotary switch SW6 are located on top of the DLC170AD
PCB (see Figure 15 ) and determine the operating configuration of the DLC170AD as follows.
• Switch SW1—Controls various video functions, such as the video characteristics (AGC, pedestal,
standby signal type, and line rate) and the loss of video alarm.
