❓ Frequently Asked Questions (FAQ)
Q1: How does the automatic switching of the Kramer VP-211DS work?
The VP-211DS automatically detects the presence of an active VGA signal on its two inputs. You configure the priority input (IN 1 or IN 2) via the DEFAULT SELECT switch located under the device. As long as a signal is present on the priority input, it remains routed to the output. If the signal on the priority input disappears, the switch automatically switches to the secondary input. As soon as the priority signal returns, the switcher automatically switches back to it. Stereo audio always follows the video during switching (audio-follow-video).
Q2: What video resolutions are supported by this VGA switch?
The Kramer VP-211DS supports all standard resolutions VGA, SVGA, XGA, SXGA, and UXGA, as well as higher resolutions thanks to its 300 MHz bandwidth. This includes: 640x480 (VGA), 800x600 (SVGA), 1024x768 (XGA), 1280x1024 (SXGA), 1600x1200 (UXGA), and even widescreen resolutions like 1920x1200 (WUXGA). The 300 MHz bandwidth ensures perfect image quality even at the highest resolutions without signal degradation.
Q3: What is the purpose of the loop output?
The loop output is an additional VGA output that is permanently connected to input 1. It allows you to connect an additional screen or projector that will always display the content from the source connected to IN 1, regardless of the input selected on the main output. This feature is useful in presentation rooms where you want a control screen to always display a specific source while the main output switches between different sources.
Q4: Are the power supplies provided with the 3 units?
No, this lot includes the 3 VP-211DS switches in their original boxes but without their power adapters. Each unit requires an external 12V DC power supply delivering at least 100-105 mA. You will need to obtain 3 separate 12V DC power adapters (with a compatible connector) to power the three units. These power supplies are readily available commercially. Make sure the polarity is correct when connecting.
Q5: Can we manually force the switching between inputs?
Yes, the VP-211DS has a REMOTE connector that accepts dry contacts allowing for manual switching between inputs, thus overriding the automatic mode. You can connect an external push button, a wall control panel, or an automation system to manually trigger the switching between sources. This function is ideal for presentations where you want to precisely control the timing of the switch without relying on automatic signal detection.
Q6: What is KR-ISP technology and what is it used for?
KR-ISP (Kramer Integrated Sync Processing) is a proprietary synchronization signal processing technology developed by Kramer. It automatically restores and reconstructs the sync signal (horizontal sync Hs and vertical sync Vs) when it is too weak or degraded. The Hs and Vs switches located under the device allow switching between NORMAL mode and KR-ISP mode. This technology ensures a stable and clear image even when the VGA source delivers a poor quality sync signal, avoiding unstable images, flickering, or loss of synchronization.
Q7: Is this Kramer equipment compatible with modern screens and projectors?
Yes, the VP-211DS is fully compatible with all screens, projectors, and monitors equipped with a standard VGA input (HD-15 15-pin connector). Although VGA connectivity is considered legacy, it remains very prevalent in many professional, educational, and industrial environments. If you wish to connect the output to a modern screen equipped only with HDMI or DisplayPort inputs, you can use a VGA to HDMI converter (not included) downstream of the switch. The analog VGA quality of the VP-211DS with its 300 MHz bandwidth provides excellent results even at high resolutions.
Q8: Are the 3 units in the lot in good working condition?
Yes, the 3 Kramer VP-211DS switches in this lot are in very good condition and have been carefully stored in their original boxes. The equipment has been tested and is guaranteed to be functional. We offer a 30-day seller warranty covering operational defects and hardware failures. If you encounter a problem with any of the units during this period, contact us for an exchange or refund according to eBay's terms. The presence of the original boxes reflects the care taken in preserving this professional equipment.
