Ds80249 P Rev 12 Schematic [exclusive]

The DS-80249 P Rev 12 refers to a specific motherboard revision used in Hikvision Digital Video Recorders (DVRs), most notably within the DS-7200 series. Schematics for these boards are critical for component-level repair, particularly when addressing common hardware failures. Board Overview and Context

This motherboard is a central component in Turbo HD DVR systems. The "P Rev 12" designation signifies a specific hardware iteration, often featuring improvements in power management or signal stability over earlier revisions.

Primary Function: Integrates video processing, storage management (SATA), and network communication.

Power Requirements: Typically operates on a 12V DC supply. A common repair scenario involves diagnosing why the DVR fails to boot or displays a "No Signal" error, often traced back to power rail failures on the motherboard. Key Sections in the Schematic

A full schematic for this board revision typically includes several critical subsystems:

Power Management (PWM): Circuits that step down the 12V input to lower voltages (e.g., 5V, 3.3V, 1.2V) required by the CPU and memory chips. Faulty capacitors or regulators in this section are frequent causes of "dead" units.

Video Input/Output (BNC & HDMI): The routing for analog BNC inputs and digital outputs like HDMI and VGA.

DS80249 P Rev 12 refers to a specific printed circuit board (PCB) revision, typically associated with equipment—specifically the Generation 2 (PLTN-RB1V1) touchscreen console Schematic Availability

Finding a full, official schematic for the DS80249 P Rev 12 is difficult because these are proprietary designs not released to the public by the manufacturer. However, repair communities and board-level technicians have identified key components and common failure points for this specific revision: Processor/SoC

: Usually based on a Rockchip or similar ARM-based architecture designed for Android tablets. Power Rail Failures

: Rev 12 boards often suffer from "no power" issues caused by a shorted capacitor or a failed voltage regulator near the DC input jack. Backlight Circuit

: If the screen is dark but the console has power, the LED driver circuit (often a small 6-pin or 8-pin IC) is likely the culprit. Common Troubleshooting Steps If you are attempting a repair on this board: Check Input Voltage : Ensure 12V is reaching the board from the power adapter. Visual Inspection

: Look for charred components near the power management IC (PMIC). Diode Mode Testing

: Use a multimeter to check for shorts to ground on the main inductors (coils). If an inductor shows 0 ohms to ground, a component on that power rail is shorted. Where to Find More Detail Since the raw schematic file (

The identifier DS80249 P Rev 12 typically refers to a specific hardware revision of a motherboard or circuit board, most commonly found in Hikvision Digital Video Recorders (DVRs) or similar surveillance equipment. Identification & Context

Device Type: This part number is associated with the internal mainboard of security recording devices.

Revision History: The "Rev 12" indicates a specific version of the board's design. Schematics for these proprietary boards are generally not released to the public by the manufacturer and are often restricted to authorized service centers. Finding Schematic Information

While the full official schematic diagram is rarely hosted on public websites, technicians often look for specific board-level information for the following tasks:

Password Resets: Many users searching for this board version are attempting to perform a hardware factory reset. This usually involves shorting specific pins (often labeled J1, TP, or similar) while powering on the device.

Component Identification: Repair forums (such as IndiaFix or specialized CCTV technician groups) sometimes host hand-drawn diagrams or high-resolution photos of the board for identifying blown capacitors or voltage regulators.

Technical Support: For official documentation, you should check the Hikvision Support Portal or use tools like the SADP Tool for software-based configuration and recovery. Safety and Warranty Warning

Attempting to repair or modify the DS80249 board using unofficial schematics can permanently damage the unit and will void the manufacturer’s warranty. If you are looking for a specific pinout or voltage rail measurement, it is safer to consult with a certified electronics repair professional.

Based on the part number DS80249 and the revision P Rev 12, you are looking at the schematic and technical documentation for the NVIDIA GeForce GTX 570 graphics card.

Here is a detailed write-up regarding this specific schematic and its significance.

1.5. Auxiliary Circuitry (LEDs, Card Detection)

Practical Application: Troubleshooting with Rev 12

Assume you have the DS80249 P Rev 12 schematic open, and your physical board has no output on the 3.3V rail.

  1. On the schematic: Locate the 3.3V regulator section (likely a buck converter).
  2. Check the feedback resistors: Rev 12 might specify R15 = 10k and R17 = 2.2k. Measure these on your physical board.
  3. Check the switching node: Use an oscilloscope (with an isolation transformer for safety) to probe the gate of the MOSFET. Compare the waveform to the Rev 12 timing diagram (if available).
  4. Look for Rev 12 specific errata: Does the schematic have a note saying "For Rev 12, add 100uF capacitor across C33 to address voltage droop"? If your board lacks that cap, you have your answer.

1. Identification and Context

The designation DS80249 is the internal NVIDIA reference design schematic number for the GeForce GTX 570 graphics card. The "P" typically denotes the production or a late-stage prototype revision, and "Rev 12" indicates the specific iteration of the board layout.

In the world of GPU repair and hardware analysis, reference schematics are the "Holy Grail." While NVIDIA designs the chip and the reference board (found in "Founders Edition" cards), they license the design to partners like ASUS, EVGA, MSI, and Gigabyte. Consequently, the DS80249 schematic serves as the foundational blueprint for almost all GTX 570 cards manufactured during that generation (circa late 2010 to 2011).

Key sections to expect in Rev 12 schematic

  1. Power
    • Main input rails (e.g., VIN, 5V, 3.3V, 1.2V).
    • Voltage regulators (buck/linear), enable pins, sequencing.
    • Power-good (PG) signals, bulk and local decoupling capacitors, ferrite beads.
  2. Grounding and return strategy
    • Single-plane vs split analog/digital GND.
    • Ground vias and star points near major ICs.
  3. Clocking and reset
    • Crystal/oscillator circuits, load capacitors.
    • Reset circuitry, supervisors (POR), manual reset header.
  4. Major ICs and interfaces
    • Processor / MCU / FPGA pinouts and power domains.
    • Memory devices (DDR/Flash) with termination and routing notes.
    • Peripheral controllers (Ethernet PHY, USB transceivers, PMICs).
  5. I/O and connectors
    • External connectors (JTAG, UART, GPIO headers, power input).
    • Pin mappings and protection (TVS diodes, series resistors).
  6. Signal integrity and protection
    • Controlled-impedance nets, differential pair routing callouts.
    • ESD protection, current-limiting, polyfuses for power inputs.
  7. Passive components and BOM references
    • Standard reference designators, footprints, and key component values.
  8. Test, programming, and debug
    • Test points for rails and critical nets.
    • Programming headers and mode-straps.
  9. Revision notes (what typically changes in a Rev 12)
    • Minor fixes: net corrections, component value updates.
    • Added silkscreen clarifications, updated footprints.
    • BOM substitutions (equivalents) and ECOs marked on schematic.

Step 4: Check the reset sequencing circuit

Rev 12 adds a dedicated supervisory circuit (U3, e.g., MAX809) on the RST_IN line. This ensures the card is properly deactivated during host brownouts. If your schematic lacks this, it is not a true Rev 12.
