Frequently Asked Questions - 613RT Kramer
How do I connect the Kramer 613RT?
Connect your HDMI source (e.g., camera, computer) to the HDMI input port. Then connect a 3G-SDI cable from the SDI output port to your SDI monitor or device. Make sure both devices use the same video standard.
What resolutions does the 613RT support?
The converter supports a wide range of resolutions, including 1080p@60Hz, 720p@60Hz, and 2160p@30Hz (via 3G-SDI). It also handles standard broadcast formats such as 1080i and 720p.
Does the 613RT support 4K?
Yes, for 4K signals it supports 3840x2160 at 30Hz over SDI. For higher frame rates like 4K@60, a different converter with 12G-SDI is required. The 613RT is optimized for 3G-SDI.
How do I power the 613RT?
Connect the included 5V DC power adapter to the power input jack. The unit automatically powers on; there is no separate power switch.
Why is there no video output on my SDI monitor?
First, verify that the HDMI cable is securely connected and the source is outputting a signal. Check the SDI cable for proper BNC connections. Confirm that your monitor supports the output format. Also, try using a different SDI cable or re-seating the HDMI connection.
Can I use the 613RT with a computer?
Yes, the 613RT works with any computer with an HDMI output. Simply plug it in and it will automatically detect the signal. No additional drivers are needed.
How do I update the firmware?
The 613RT typically does not require firmware updates for basic operation. If an update is needed, you can download it from the Kramer website and use the USB port (if available) with a programming tool. Refer to the user manual for specific instructions.
Is the 613RT compatible with Mac computers?
Yes, the 613RT is operating system independent. It works with any Mac, PC, or other device that has an HDMI output, as long as the video format is supported.
What is the difference between SDI and HDMI?
SDI (Serial Digital Interface) is a professional broadcast standard using BNC cables for long-distance, reliable transmission. HDMI is a consumer standard for short distances. The 613RT converts HDMI signals to SDI for use in professional environments.
How do I clean and maintain the device?
Always disconnect the power before cleaning. Use a soft, dry cloth to wipe the exterior. Avoid using water, solvents, or abrasive cleaners. Inspect connectors regularly and keep them free from dust and debris.
