The model identifier DVBS-EVB-KD1100HD-V1.1 denotes a specific revision of an evaluation board (EVB) for a DVB-S (Digital Video Broadcasting – Satellite) receiver, supporting high-definition (HD) decoding. Designations like this are common in the lifecycle of set-top box (STB) chipsets, where “KD1100HD” likely refers to a main SoC (System on Chip) or tuner/demodulator combination, and “V1.1” indicates a minor revision after initial prototyping. Such boards serve as reference designs for manufacturers, allowing software development, performance validation, and certification before mass production.
Without more specific information, it's challenging to provide detailed purchasing information, technical specs, or software/firmware details for the "dvbs-evb-kd1100hd-v1.1".
DVBS-EVB-KD1100HD-V1.1 is a specific hardware revision for a Digital Video Broadcasting (DVB-S) satellite receiver motherboard. These boards are commonly found in budget HD satellite decoders and are often associated with Sunplus chipsets. Technical Overview
Based on common configurations for this board family, here are the likely technical specifications: Often utilizes the Sunplus 1506G
or similar budget processors, which are popular in the Middle East and South Asian markets for their "access control" and "patch" capabilities. Resolution: Supports Full HD 1080p output via HDMI. Connectivity: LNB IN (Satellite dish input) HDMI and AV (RCA) outputs
Dual USB ports (typically one front, one back) for Wi-Fi dongles or PVR functions.
RS232 port (often a 3-pin mini-jack) used for recovering "bricked" devices via a PC. Common Troubleshooting & Maintenance
If you are working with this board, you are likely looking for one of the following: Firmware/Dump Files: Tech enthusiasts often seek
files for this board to upgrade the UI or unlock features like IKS (Internet Key Sharing). Since the V1.1 revision is hardware-specific, ensure any firmware you flash matches the (or relevant) chipset to avoid a "No Match" error. Power Issues: dvbs-evb-kd1100hd-v1.1
If the receiver is dead, check the electrolytic capacitors on the board near the power input. These are common failure points in the KD1100HD series. Software Recovery:
If the device is stuck on "Load" or "On," you may need to flash the original dump file using a Sunplus Loader Tool via the RS232 port. Expert Tip Before flashing any new software, always backup your current "Dump" file
to a USB drive using the receiver's menu. This is your only safety net if the new firmware is incompatible with your specific V1.1 tuner or remote control configuration.
The DVBS-EVB-KD1100HD-V1.1 is a specialized evaluation board (EVB) designed for the development and testing of High Definition (HD) digital satellite receivers. These boards typically serve as a reference design for engineers to verify the performance of specific chipsets before moving to mass production of set-top boxes (STBs). Key Technical Aspects
While specific public datasheets for this exact version are often restricted to manufacturer-client portals, evaluation boards in this series generally feature the following:
