9. If an extension cord must be used with this unit, make sure that the total of the
ampere ratings on the products plugged into the extension cord do not exceed the
extension cord’s rating.
10. Make sure that the total amperes of all the units that are plugged into a single wall
outlet do not exceed 15 amperes.
11. Never push objects of any kind into this unit through the cabinet ventilation slots,
as they may touch dangerous voltage points or short out parts that could result in
risk of fire or electric shock. Never spill liquid of any kind onto or into this unit.

Disposal
For EU Customers only - WEEE Marking
This symbol on the product or on its packaging indicates that this
product must not be disposed of with your other household
waste. Instead, it is your responsibility to dispose of your waste
equipment by handing it over to a designated collection point for
the recycling of waste electrical and electronic equipment. The
separate collection and recycling of your waste equipment at the
time of disposal will help to conserve natural resources and
ensure that it is recycled in a manner that protects human health and the environment.
For more information about where you can drop off your waste equipment for recycling,
please contact your local city office, your household waste disposal service or the shop
where you purchased the product.
CE Marking is the symbol as shown on the left of this page. The
letters "CE" are the abbreviation of French phrase "Conformité
Européene" which literally means "European Conformity". The
term initially used was "EC Mark" and it was officially replaced by
"CE Marking" in the Directive 93/68/EEC in 1993. "CE Marking" is
now used in all EU official documents.

1. Introduction
The DAC-50S converts the digital HD/SD-SDI video input to one of the
following analog output combinations:
•one component (YUV) output + one composite (CV) output;
•one S-Video (Y/C) output + two composite (CV) outputs,
with both of which paired with two analog audio outputs (R and L). The
outputs can be easily connected to analog video monitor or deck devices
such as BataCAM and VHS. The DAC-50S is also able to scale down the signal
to connect analog output ports to SD analog equipment.
The DAC-50S provides an SDI Loop-thru output, which makes it suitable for
more different applications. It further outputs one pair of analog audio
channels selected from 16 de-embedded SDI audio channels (Selection is
determined by DIP switch settings).
The DAC-50S is housed in a rugged aluminum frame, making it durable
enough to endure even in the roughest conditions. It is also suitable for 2U
rack mount kit of RMK-2 on standard rack, and fits the battery holder of MB-
4.
Features
•Converts 3G/HD/SD-SDI input to analog video and 2 unbalanced analog
audio channels.
•Two available output combinations:
-one analog component (YUV) output + one composite (CV) output
-one analog S-Video (Y/C) output + two composite (CV) outputs
•Supports NTSC / PAL output.
•Define de-embedded audio channels sent to analog audio outputs via a
DIP switch.
•Solid aluminum housing that fits the 2U rack mount kit of RMK-2 and
battery holder of MB-4.

NOTE: Given a 16:9 HD video input, if DIP SW5 is set to 16:9, the image displayed on a
4:3 TV monitor will be anamorphic, i.e. the image will be compressed laterally.
However, if DIP SW5 is set to 4:3, the image displayed on a 4:3 TV monitor will
become edge-cropped, i.e. the left and right of the image will be partially cut off. The
diagram below provides an illustration of the above.
For an SD video input, if the input resolution is 16:9, set DIP SW5 to 16:9; if the input
resolution is 4:3, set DIP SW5 to 4:3.

3. Firmware Update
From time to time, Datavideo may release new firmware to either add new features or
to fix reported bugs in the current DAC-50S firmware. Customers can update the
firmware themselves if they wish or they can contact their local dealer or reseller for
assistance should they prefer this method.
This section describes the firmware update process. Once started, the update process
should not be interrupted in any way as this could result in a non-responsive unit.
Host Update
1. Set DIP SW8 to ON
2. Connect DAC-50S to the PC using a USB cable (DAC-50S is powered by the USB port
so external power source is not required)
3. A USB device connection prompt window will appear on the PC screen (DAC-50S
USB) and click “Open device to view files” to open the device.
4. Copy the new firmware file and paste it into the USB device to replace the existing
firmware file on the device.

12
5. After the new firmware file has been saved in the device, safely remove the USB
device VP733 Datavideo Tech USB Device as shown in the diagram below.
6. Update is complete after the device is safely removed, unplug the USB cable and set
DIP SW8 to OFF.
FPGA Update
1. Set DIP SW7 / SW8 to ON.
2. Connect the power to the device.
3. Use the mini-USB cable to connect the device to the computer, which will
automatically detect the device.
4. Open the device drive.

13
5. Delete the existing file and copy the latest FPGA firmware file into the device.
6. The firmware update will now start, which takes approximately 2 minutes.
7. After the firmware file is successfully copied into the device, safely remove the USB
device.
8. Set DIP SW7 / SW8 to OFF to complete the update.

4. Frequently-Asked Questions
This section describes problems that you may encounter while using DAC-50S. If you
have questions, please refer to related sections and follow all the suggested solutions. If
problem still exists, please contact your distributor or the service center.
No.
Problems
Solutions
1.
Severe color bar noise is seen on
the DAC-50S output terminal if
the SDI-IN source is a 100% color
bar.
DAC-50S does not support 100% color
bar and downgrading it to 75% will
solve this issue.
