Configuring the DLC170DA
This section describes how to configure the operation of the DLC170DA. 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 rotary switch SW4 located on top of the DLC170DA PCB (see
Figure 15 for switch
locations), determine the operating configuration of the DLC170DA as follows:
• Switch SW1—Controls various video functions of the DLC170DA, such as source selection (SFP,
backplane), video characteristics (pedestal) and the loss of video alarm.
• Switch SW2—Controls various audio characteristics of the DLC170DA (enable, format, and source
group), determines if the DLC170DA acts as a repeater, and enables the EMS override function.
• Switch SW4—Controls the peak analog audio level that the DLC170DA produces.
Artel ships the DLC170DA configured as follows:
• Video source is optical SDI from the SFP
• Analog video pedestal enabled
• Analog video enabled through the BNC connector
• Alarm disabled for no video present
• Analog audio output
• +20 dBm (600 Ohms) peak audio level
• Audio de-embed enabled from group #1
• Optical repeating disabled
• EMS override enabled (DL Manager can change the DLC170DA configuration)
Note: In addition to the configuration information contained in the section, the DLC170DA has a
switch legend located on the bottom of the module that you use to configure the switches.
This section contains the following topics:
• Configuring Video Functions with DIP Switch SW1 (page 26)
• Configuring Audio Characteristics with DIP Switch SW2 (page 28)
• Configuring Peak Analog Audio Level with Rotary Switch SW4 (page 29)
Configuring Video Functions with DIP Switch SW1
Switch SW1 controls various video functions of the DLC170DA, such as the source selection and video
characteristics, including pedestal and the analog/digital video output. This switch also enables the loss of
video alarm function.
Figure 16 shows the DLC170DA configuration switch SW1 located on top of the PCB.
