The **AK-PS2-R** typically refers to a specific type of **PS/2 to USB Adapter** or a specialized **PS/2 Power/Signal Cable Assembly** (often associated with Akasa or similar industrial PC hardware manufacturers). Below is a breakdown of the electronic components and technical specifications associated with this part. --- ### 1. General Technical Specifications | Feature | Description | | :--- | :--- | | **Connector A** | PS/2 6-pin Mini-DIN (Male/Female depending on variant) | | **Connector B** | USB Type-A (Male) or specialized 4-pin header | | **Wiring** | Shielded Copper Conductors | | **Voltage Rating** | 5V DC | | **Material** | PVC Outer Jacket with Nickel-plated connectors | --- ### 2. Internal Electronic Structure The AK-PS2-R is not just a physical wire bridge; it often contains a small integrated circuit (IC) or specific pin-to-pin mapping to bridge legacy hardware with modern interfaces. #### A. The Passive vs. Active Logic * **Passive Components:** If the device being connected (like a mouse) is "Combos-capable," the cable simply maps the PS/2 pins to the USB pins. * **Active Logic (The Converter Chip):** Most AK-PS2-R units act as **Active Converters**. They contain a small microcontroller that translates the **Synchronous Serial Protocol** (PS/2) into the **USB HID (Human Interface Device) Protocol**. #### B. Pinout Configuration The 6-pin Mini-DIN connector is wired based on the following electronic standards: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | +DATA | Key/Mouse Data Signal | | **2** | Reserved | Usually N/C (No Connection) | | **3** | GND | Ground | | **4** | VCC | +5V Power Supply | | **5** | +CLK | Clock Signal | | **6** | Reserved | Usually N/C | --- ### 3. Key Electronic Features * **EMI Shielding:** The internal wires are usually wrapped in aluminum Mylar foil with a braid to prevent Electromagnetic Interference (EMI) from degrading the clock signal. * **Plug-and-Play (PnP):** The internal IC identifies itself to the Operating System as a standard HID device, requiring no external drivers. * **Hot-Plugging Support:** Unlike native PS/2 ports (which can short-circuit if plugged in while the PC is on), the electronics in the AK-PS2-R allow for safe USB hot-swapping. --- ### 4. Common Use Cases 1. **Legacy Integration:** Connecting mechanical "Model M" style keyboards to modern laptops. 2. **KVM Switches:** Used in server racks where KVM (Keyboard, Video, Mouse) switches utilize PS/2 inputs for stability. 3. **Industrial PCs:** Connecting specialized input devices to modern motherboards that lack legacy ports.
