Frequently Asked Questions - DA3-24-H Kramer
How do I connect the DA3-24-H to my video source and displays?
Connect your composite video source to any of the 3 input connectors using 75-ohm BNC cables. Then connect each of the 24 output connectors to your displays or monitors. Ensure all devices are powered off before connecting.
What power supply does the DA3-24-H require?
The unit operates on a 12 V DC power supply and comes with an external 12 V DC, 1 A adapter. Plug the adapter into the rear panel power socket and the other end into a mains outlet. The unit powers on immediately.
Can the DA3-24-H be mounted in a 19-inch rack?
Yes, it has a standard 19-inch rack mount design with included mounting ears. Each ear can be attached to the sides, and then secured to the rack rails with standard screws. The unit occupies 1 U (unit) of rack space.
How should I clean and maintain the device?
Always power off the unit before cleaning. Use a soft, dry cloth to gently wipe the exterior. Avoid using liquids, sprays, or solvents, as they may damage the finish or enter the cabinet. No internal cleaning is needed.
What video resolutions are supported?
The DA3-24-H supports composite video signals with resolutions up to 1080i or 720p (depending on the source). The bandwidth of 100 MHz ensures sharp images for standard and high-definition composite formats.
Does the DA3-24-H amplify audio signals?
No, this model is designed specifically for video distribution. Audio signals are not processed or amplified. It should not be used for audio transmission.
Why do some outputs not show a signal?
Check that the input cable is firmly connected to one of the input connectors. Confirm that the source device is outputting a valid signal. Also, verify the display's input is set to the correct channel. Try swapping outputs to check if the specific output port is faulty.
How long can the video cable be from the source to the unit?
The unit has built-in cable equalization, which compensates for signal loss on long runs. For best results, use 75-ohm coaxial cable with quality BNC connectors. Typical supported cable lengths exceed 100 meters, but the maximum depends on cable quality and signal rate.
Is there a warranty for the Kramer DA3-24-H?
Kramer products typically come with a limited warranty of at least one year. Check the invoice from your dealer for exact warranty terms. Keep your receipt as proof of purchase for service claims.
What should I do if the device is not working?
First, ensure the power adapter is connected properly and the power LED is lit. If there is no LED, try a different adapter with the same specifications. If it still fails, do not open the unit; contact Kramer technical support for further assistance.
