Frequently Asked Questions - DAC-50S DataVideo

How do I switch between component YUV output and S-Video output?

Set DIP SW6 to the desired position: OFF for YUV+CV OUT, ON for Y/C+2xCV OUT.

How can I select which audio channels are output?

Use DIP switches SW1, SW2, and SW3 to select the desired pair of audio channels from the 16 de-embedded SDI channels. Refer to the DIP switch table in the manual.

What should I do if I see severe color bar noise?

The DAC-50S does not support 100% color bar. Downgrade the color bar to 75% to resolve the issue.

How do I update the host firmware?

Set DIP SW8 to ON, connect the DAC-50S to a PC via USB, copy the new firmware file to the device, safely remove the device, then set DIP SW8 to OFF.

How do I update the FPGA firmware?

Set DIP SW7 and SW8 to ON, connect power and mini-USB to PC, delete existing file, copy new FPGA firmware, safely remove, then set both switches to OFF.

How do I change the aspect ratio between 16:9 and 4:3?

Use DIP SW5: set to ON for 4:3 (edge-crop), OFF for 16:9 (anamorphic). For SD input, match the input resolution.

What is the difference between IRE 7.5 and 0 IRE?

IRE 7.5 is used for NTSC with setup, while 0 IRE is used for NTSC without setup or PAL. Select via DIP SW4.

Why is my analog output blank or distorted?

Check that the input format is supported and DIP switches are set correctly for output mode and aspect ratio. Also verify that the SDI input is valid.

Can I rack mount the DAC-50S?

Yes, it fits the 2U rack mount kit RMK-2. It is also compatible with the battery holder MB-4.

What is the power consumption and how do I connect power?

The DAC-50S requires DC 12V at 0.5A (6W). Use the supplied PSU and secure the DC connector by screwing the outer ring.

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 Européenne" 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.

1. 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.

1. 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.

1. Delete the existing file and copy the latest FPGA firmware file into the device.
2. The firmware update will now start, which takes approximately 2 minutes.
3. After the firmware file is successfully copied into the device, safely remove the USB device.
4. 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.
