Questions & Answers

What is the correct way to convert and extend a video signal?
Convert the video signal as close to the source as possible, then extend the converted signal using a compatible video extender. Explanation: When both signal conversion and extension are required, the conversion should occur before the signal is extended. Placing the video converter near the source device ensures the signal is converted to the desired format early, which improves compatibility and signal stability over long distances. After conversion, a video extender should be used to transmit the signal over the required distance while maintaining the same video standard end-to-end. For example, to send a VGA signal to a distant HDMI display, first convert VGA to HDMI at the source, then use an HDMI extender to carry the signal to the display. This approach minimizes signal degradation and ensures the extender operates with a consistent signal type throughout the transmission.

What DC barrel connector power plug types do StarTech.com products use, and what are their dimensions?
StarTech.com DC barrel connector plug types are defined in the “Plug Type” field of the technical specifications, using a letter code that specifies the connector’s outer diameter (OD) and inner diameter (ID) in millimeters for power adapter compatibility. Explanation: In StarTech.com technical specifications, the “Plug Type” field is a standardized identifier for the exact DC barrel connector size required to power a product. Each plug type is assigned a letter code that corresponds to a specific combination of outer diameter (OD) and inner diameter (ID), measured in millimeters. Common DC barrel plug type dimensions Plug Type OD ID A 2.35 mm 0.7 mm B 4.0 mm 1.7 mm C 4.75 mm 1.7 mm H 3.4 mm 1.3 mm L 5.0 mm 2.5 mm M 5.5 mm 2.1 mm N 5.5 mm 2.5 mm The DC barrel connector plug type must match both the outer diameter and inner diameter exactly. A mismatch between the StarTech.com product requirement and the power adapter connector can prevent proper fit or stable power delivery, which may result in device startup failure or intermittent operation. The plug type defines only the physical connector size. The plug type does not define electrical power requirements such as voltage, current, or polarity. The power adapter used with a StarTech.com product must match the product’s specified electrical requirements. Using an incompatible power adapter can cause device malfunction or permanent damage. This standardized DC barrel connector plug type system enables IT professionals and procurement teams to verify connector dimensions, ensure power adapter compatibility, standardize hardware deployments, and identify the correct replacement power supply for StarTech.com products.
