• Standby Video Generator that allows audio to be delivered in an SDI grey eld when input video is
lost
• Selectable non-video keep-alive signal that maintains link operation while allowing downstream
equipment to detect loss of signal when input video is lost
The DLC150E can be cascaded using the backplane inputs and outputs for multi-group embedding.
The DLC150E uses industry standard 1310nm, 1550nm, and CWDM Small Form Factor Pluggable (SFP) optics.
You provision and monitor the DLC150E using onboard switches, status indicators, front panel monitor jack, or
Artel’s DL Manager, which is an element management system (for more information, see the
DL Manager Setup and Operations Manual).
DLC150E Laser Warnings
The SFP module used in the DLC150E has a transmitter that contains a Class 1 laser. You must adhere to the
standard safety practices for handling a Class 1 laser product, including the following warning.
Warning
Never stare directly into a ber optic connector.
Although the light used in most ber optic transmissions is not visible to the naked eye, potentially
harmful levels of radiation may be present at the optical output ports and unconnected transmit ber
ends.
Failure to observe this warning could result in personal injury.

DLC150E Module Functional Description
DLC150E Module Functional Description
This section provides a functional description of the DLC150E. Figure 1 shows the functional block diagram for
the DLC150E.
Figure 1. DLC150E Module Functional Block Diagram
This section contains the following topics:
• Video Signal Paths (page 3)
• Audio Signal Paths (page 4)
• Electrical Outputs (page 4)
• Optical Inputs and Outputs (page 4)
Video Signal Paths
The DLC150E accepts digital video signals from the following sources:
• 75Ohm BNC connector—Located on the rear panel of the module, this is the most commonly used
input.
• Another function module in the host chassis—Signals from other modules in the chassis can be
received through the backplane.
• Optical input—The optical input of the DLC150E.

4DLC150E Function Module Installation and Operations Manual
DLC150E Function Module
You select the digital video source using either the module switches or the management card software. When
no video is available on the selected input, the DLC150E enables the standby video generator, which you can
congure for one of the following signal types:
• Grey screen into which audio can be embedded
• 525 lines (NTSC)
• 625 lines (PAL)
• Non-video keepalive
Use the non-video keepalive signal to keep the optical link alive when an application requires that the standby
video generator not produce a detectable video signal.You cannot embed audio into the non-video keepalive
signal.This signal is detected by other host chassis modules, such as the DLC103A, so that they can signal that
a keepalive signal is intentionally being sent across the optical link. Whenever the DLC150E is transmitting the
grey screen or the non-video keepalive signal, the TX LED on the front panel illuminates amber.
When the DLC150E detects that the selected digital video signal is SDI or SDTI, it passes the signal through the
Embed and EDH logic. Otherwise, the DLC150E passes the digital video signal directly to the electrical-to-
optical circuits.
Audio Signal Paths
The DLC150E accepts audio signals through a quad three-pin terminal block consisting of 12 pins. This
terminal accepts up to four balanced audio signals inputs, each with a +, -, and ground. The DLC150E samples
each of the four analog audio signals and converts them to digital.The digitized signals are then paired and
encoded into an AES-3 stream that the DLC150E embeds into the digital video.
AES-3 digital audio is supplied to the DLC150E using only two of the four balanced inputs (channels A and C). If
the digital audio is asynchronous, the DLC150E matches its rate to the digital video stream and then embeds
the audio into the digital video.
Electrical Outputs
The DLC150E makes the electrical signal available through the backplane for possible use by other modules in
the host chassis.
The front-panel monitor jack is a mini 75Ohm SMB connector that allows you to monitor either the DLC150E
output or the selected digital video input.
Optical Inputs and Outputs
The optical interface is provided by a single SFP socket.The SFP modules use LC/PC connectors. Optical
performance is dependant the quality of your optical ber and ber interconnects, and on the selected SFP
module, which must be specically qualied by Artel to pass video signals. Consult Artel for available SFP
options.

Conguring the DLC150E Module
Conguring the DLC150E Module
This section describes how to congure the operation of the DLC150E. You must congure the module while it
is out of the host chassis because the conguration switches are mounted to the top of the module PCB.
The following set of switches control the operating conguration of the DLC150E:
• DIP switch SW2—Controls the termination of the analog audio inputs.
• DIP switch SW4—Controls the signal source selection for the digital video, type of audio, and
destination group for the embedding.
• DIP switch SW5—Controls multiple module operating states, including conditional embedding,
non-video keepalive signal, line rate for the standby video pattern, digital audio rate converter
operation, optional alarm suppression for an uninstalled SFP, and EMS control mode
• Rotary switch SW3—Controls the peak analog audio level that can be handled without clipping.
See Figure 2 for switch locations.
Artel ships the DLC150E congured as follows:
• Analog audio mode set to 24 bits.
• Analog audio source with 600 Ohm termination
• +20dB peak audio level without clipping
• Asynchronous audio embed into destination group #1
• Digital video enabled through the BNC connector
• SDI grey eld enabled if no video is present at the NTSC rate
• Alarm enabled if no SFP is present
• EMS override enabled (DL Manager can change the DLC150E conguration)
Note: In addition to the conguration information contained in the section, the DLC150E has a switch
legend located on the bottom of the module that can be used to congure the switches.

Conguring DIP Switch SW5
Switch SW5 (see Figure 5) controls several module modes including conditional embedding, standby video
pattern or the non-video keep-alive signal, line rate for the standby video pattern, digital audio rate converter
operation, optional alarm suppression for an uninstalled SFP, and EMS control mode.
Figure 5. DLC150E Conguration Switch SW5
This section contains the following topics:
• Understanding Conditional and Unconditional Audio Embedding (page 10)
• Understanding DIP Switch SW5 Conguration Options (page 10)
Understanding Conditional and Unconditional Audio Embedding
If the incoming SDI has audio embedded in it already, the DLC150E provides the option of over-writing the
embedded audio. Switches S1 and S2 of DIP switch SW5 control this feature.
The default setting with S1 and S2 both set to ON selects conditional embedding. The DLC150E embeds audio
into the group selected by SW4 only if there is no audio already present in the group. If the SDI contains
embedded audio when it is applied to the DLC150E, it passes through for transmission unaltered. If there is no
embedded audio present, the DLC150E embeds the local audio as congured.
Setting S1 to ON and S2 to OFF selects unconditional embedding. The DLC150E always embeds audio into the
group selected by SW4 even if audio is already embedded in the group. If there is audio in the selected group,
it is over written. Audio in other groups are not aected.
When the audio applied to the DLC150E must always be embedded, then use unconditional embedding with
S1 set to ON and S2 set to OFF to insure that the program audio is not replaced by previously embedded
audio. However, when it is unknown if the incoming video might contain embedded audio or not, you can use
the conditional mode to allow the DLC150E to automatically embed or not embed depending on the video
content.
Understanding DIP Switch SW5 Conguration Options
Table 4 describes the DIP switch SW5 conguration options. The factory-set conguration settings are shown
